INTRODUCTION
The SE-02's monophoni synthesizer engine features three voltage- ontrolled os illators, a voltage- ontrolled
24 dB low-pass filter, and a dual gain-stage amplifier. The os illators have six different kinds of waveforms with
the warmth and omplex hara ter asso iated with true analog VCOs. What’s more, these VCOs are
temperature stabilized with automati tuning, so you get all the benefits and none of the downsides.
The SE-02 is big and bold, with thi k, ri h lows and lear, vibrant highs—exa tly what you think of when you
imagine lassi vintage synth tone. And while the SE-02 an reate astonishingly great vintage sounds, it an do
so mu h more. It has three types of ross modulation (XMOD), a ripping filter feedba k loop, a tempo-syn ing
LFO with nine waveforms, envelope sweeping and inverting, os illator syn , a noise generator, and a tempo-
syn ing delay.
While it’s a ompa t “go-anywhere” devi e, the knobs, swit hes, and buttons are sturdy and plentiful, giving you
a vast palette of sound-shaping apabilities at your fingertips. Everything is hands-on and knob-per-fun tion,
with deep ontrol and a logi al, intuitive layout. To get started, you an hoose from 384 expertly programmed
preset sounds that over a wide range of lassi and modern tones. Tweak and modify these sounds or reate
something ompletely new, storing your own ustom reations in the 128 available user lo ations.
Modern Flexibility
The SE-02 is built solidly with a rugged metal top and quality knobs and swit hes. And despite having a ontrol
for just about everything, it’s small enough to take just about anywhere. Due to its Roland Boutique format, it fits
in our K-25m or DK-01 a essory do ks, so you an add an integrated 25-key mini keyboard or have various tilt
options for easy a ess in a variety of live and studio situations.
The SE-02 also features onvenient 1/8-in h stereo ja ks that redu e able lutter, plus full-sized, standard
MIDI ja ks for onne ting any kind of keyboard you want or ontrolling the SE-02 remotely. And as with other
Roland Boutique synths, Chain Mode lets you in rease the polyphony by onne ting two or more SE-02 units
together via MIDI.
There are CV inputs for both pit h and filter frequen y, as well as trigger in and out, so the SE-02 works great
with modular setups and other vintage gear. You an route external audio signals through the filter se tion,
and there’s even USB audio and MIDI apabilities to seamlessly integrate with omputer-based setups.
A More Mu ical Sequencer
The SE-02 in ludes a powerful 16-step sequen er to add motion and dimension to your sounds. It an syn to
external tempo via MIDI, USB, or trigger input, and per-step gate time, adjustable glide, tempo, and pat h
number are stored with ea h sequen e. Creative performan e features allow you to set shuffle, s ale, dire tion,
and first/last steps on the fly. Even synth parameters an be automated by sequen ing hanges—just press a
step and move a ontrol. And despite the SE-02s ompa t size, the sequen er is fun and intuitive, lending itself
to both studio and live usage. You an store 128 sequen e patterns and onstru t 16 songs, ea h with up to
16parts.

I. GENERAL FUNCTIONS
COMMON SECTION
The Common Se tion of the SE-02 is where bank and pat h information is stored and re alled for performan e.
The first knob is the VALUE / WRITE knob.
TURNING the [VALUE] knob will s roll through data and fine tune sele tions. This knob is used for PATCH
sele tion as well as settings within the operating system.
SAVING A PATCH
CLICKING the [VALUE] knob will enter [WRITE] mode,
1. Sele t destination pat h in the USER bank
2. Confirm by li king the [VALUE] ob. A onfirmation message is displayed.
3. Can el by pressing [EXIT] on onfirm by li king [VALUE] knob.
After write, destination pat h is automati ally sele ted.
CLEARING A PATCH
1. Press the [COMP] button and [PLAY] button to make them light.
2. Press the [9] button. The display indi ates “Clear Pat h - Push VALUE.”
3. Press the [VALUE] knob. A onfirmation message appears in the display. If you de ide to an el, press
the [EXIT] button.
4. To lear the pat h, press the [VALUE] knob.
When learing is ompleted, the urrently sele ted pat h is set to the default values (available from V1.10)
Next is the MODE SELECT SWITCH where you an swit h between PATCH, SEQUENCE or SONG mode.
The buttons marked with COMP, PLAY, TRANSPOSE, OCT- and OCT+ are the FUNCTION SELECT buttons
for the ommon se tion. These perform different fun tions depending on whi h mode you are in. These are the
buttons to a ess the settings for the SE-02. In PATCH mode, use these buttons to a ess a playable, and
transposable keyboard. In SEQUENCE mode, use these buttons to hoose the type of data you wish to
sequen e - Note, Gate, Glide, Parameters, or sele t the S ale of the sequen e. In SONG mode, these buttons
edit, sele t patterns, insert and delete steps of the song’s hain.
The set of 4 buttons marked A,B, C and USER are the BANK sele tion buttons The se ond set of 16 buttons are the
PATCH sele tion buttons.
Ea h bank is 128 lo ations. There are 4 read only fa tory banks (A/B/C/D) and 1 writable user bank (USER) for saving
user sounds. To sele t a bank hoose the bank from the A, B, C or USER se tion and then sele t the pat h. Press A
twi e will all bank D. A will blink slowly to indi ate bank D is sele ted.
To sele t a pat h use the orresponding number buttons for the pat h you’d like to all up. For example: To Call up
pat h C 101 simply press BANK C, and then Button 1, Button 0 and then Button 1. You an also just s roll through
them all with the VALUE knob.

USB INTERFACE
In the past many synthesizers ame equipped with various interfa es. Conne tion methods like CV and Gate, Din
Syn , S Trig, DCB, Tape I/O allowed synthesizers to onne t to lo ks, tape ma hines, sequen ers and drum
tra ks. Thanks to the universal serial bus with whi h most personal omputers are equipped today we have a
number of interesting ways to handle these on e ompli ated and tedious operations.
The USB onne tion port an be used to:
• Pass midi as well as audio data to and from a omputer based DAW
• Mount the Synthesizer to the desktop of a omputer and ba kup and/or restore and share your pat hes.
• Mount the Synthesizer to the desktop for software updates.
NOTE: The SE-02 works differently from the other Roland Boutique modules. The USB Port will not power the
synthesizer, nor are there batteries for autonomous power. The Roland PSB 1U power supply must be used in
order to power the SE-02.
DATA BACKUP & R E S T O R E
One of the oolest things about the boutique line of modules is their ability to mount onto the desktop of any
USB enabled omputer and you an drag and drop your pat hes in order to save them.
Backup Patche from SE-02
1. Re tart the ynth holding down the [2] button.
2. Lights will dan e, this means the SE-02 is awaiting onne tion to the omputer.
3. Connect the USB cable to the omputer and a drive i on named SE-02 will appear on the desktop. It
takes a moment, so relax and trust that all is well.
4. Copy the backup files from the SE-02 drive into an appropriately named folder on your omputer
5. On e you’re done, eje t the SE-02 drive from the omputer,
6. Note that all buttons in the ommon se tion are blinking green.
7. On e noted you may power y le the SE-02 and you’re done.
Re tore patche into the SE-02:
1. Conne t the mi ro end to the SE-02 and restart the synth holding down the [3] button.
2. Copy the ba kup files, or the new pat hes you’d like to he k out into the appropriate “PATCH”,
“PATTERN” or “SONG” folder on the SE-02drive. Note only USER BANK an only be written.
3. When opying is ompleted, eject the SE-02 drive from the computer
4. Di connect USB cable
5. Buttons blink orange / red to indi ate write in progress.
6. Wait that all buttons are blinking Orange. This indi ates write is ompleted.
7. You may power y le the SE-02
Re tore the SE-02 to factory etting :
This is the pro edure for resetting your SE-02 ba k to it’s fa tory state. Remember that if you do this, all your
settings and all your sounds will be overwritten with the out of the box, fa tory fresh programming.
1. While holding down the [1] button, turn on the power.
2. The display should read “rSt”. If it doesn’t try that again. If you hange your mind and de ide not to go
through with the reset, just power off the SE-02 and then turn it ba k on.
3. To exe ute the rest press the MANUAL button
4. When the display reads “F in”, restart the SE-02 and it’ll be just the way it was the day you got it.

PRESET SECTION
Unlike the other Roland Boutique synthesizers, the SE-02 has four banks of 128 programmed presets and one
bank of 128 user presets. There’s a total of 640 pat hes (version 1.09 and up).
BANK A, B and C & D
Pre programmed pat hes are read only memory and annot be overwitten. A, B and C bank are dire t a ess
using orresponding button while D Bank is alled by pressing 2 times Bank A button. “A” button will blink. Bank
D is available with V1.10 firmware and up.
USER BANK
Ea h of these 128 pat h destinations have sounds in them, but they an be overwritten by the user to store 128
pat hes for later use, and ex hange with other SE-02 users. Only 32 first sounds are fitted when shipped from fa tory.
MANUAL MODE
In order to listen to the urrent settings of the knobs on the panel of the SE-02 simply press the MANUAL button.
This will swit h from whi hever preset is urrently sele ted to report the physi al settings of the synthesizer. To
return to the presets sele t the bank, and desired pat h number.
COMPARING PATCHES
To ompare the urrently-edited pat h with a saved pat h press the COMP button. Ea h time you press the button,
you swit h between the saved pat h (button lit) and the urrently-edited pat h (button unlit). If there are any
differen es between the urrently-edited pat h and the saved pat h, a dot appears in the display, and the entire
ontent shown in the display blinks.
USING THE COMMON BUTTONS AS A KEYBOARD
You an use the [5] – [16] buttons as a one o tave transposable keyboard to play the sound.
1.Press the PLAY button. The [5] –[16] buttons are lit.
2. Press the [5] –[16] buttons to play the keyboard
SHIFTING THE PITCH RANGE
Transpose the keyboard in +/- 1 o tave intervals with a range of +3/-3 o taves..
Press the OCT+ button or OCT– button. At one o tave, the button is lit; at two o taves, the button blinks slowly; at
three o taves, the button blinks rapidly.
TRANSPOSING THE PITCH
You an transpose the pit h in semitone units in a range of ±1 o taves.
1.Hold down the TRANSPOSE button and press the OCT+ button or OCT– button, or turning the VALUE knob. The
display indi ates the transpose value.
2.Press the [TRANSPOSE] button to turn transpose on/off.

II. FUNCTIONS FOR SOUND CREATION
CONTROL
The CONTROL se tion is where you adjust the GLIDE and MODULATION WHEEL settings for the SE-02.
GLIDE KNOB
Adjusts the timing of the portamento / glide between notes. Counter lo kwise is just about imper eptible, and
as you pro eed turning the knob to the right the effe t of the glide in reases.
GLIDE TYPE SWITCH
The type of glide is adjustable between OFF, Exponential, and Linear.
OFF - No glide effe t at all
LINEAR - A mathemati ally orre t, or linear urve is used for the glide between notes
EXPONENTIAL - A exaggerated urve whi h more a urately approximates the human ear is used for the glide.
Experiment:
Press the PLAY button to bring up the internal keyboard and play a few notes.
Sele t EXPONENTIAL GLIDE, and then rotate the knob lo kwise. Listen to the hanges between notes.
Swit h to LINEAR MODE and repeat the above exploration. Do you noti e a differen e?
Glide an make things wet, plasti , and fluid, but it is also very emotive with long, slow performan es. Spend
some time with glide, and dis over how interesting it an be.
MOD WHEEL MIX KNOB
This knob sets what the mod wheel of you r midi ontroller, or MIDI CC data for Modulation will do to the sound of
the SE-02. The knob mixes between LFO and XM. This means that at ounter lo kwise the mod wheel will only
engage the LFO. At all lo kwise the mod wheel will only engage the ross modulation. At 12 o’ lo k there will be
a mixture of 50% LFO and 50% XMOD.
Experiment:
1. Conne t the SE-02 to a ontroller keyboard with a Mod Wheel (or establish a onne tion with a DAW and
sele t MIDI CC data for sending Mod Wheel ontrollers to the SE-02.)
2. Choose a pat h you like and pay a few notes.
3. Now pend the mod wheel and listen to what’s happening.
4. Adjust the MOD WHEEL MIX KNOB and see how the results hange.

OSCILLATORS
The SE-02 is a 3 Os illator analog monophoni synthesizer and the OSCILLATOR se tion is entral to sound
reation. With three os illators mixing through a single filter/envelope se tion resulting in one synthesizer voi e
an inspiring array of sounds an be produ ed. At its root, a great bass sound an be made with a single
os illator, a se ond an be added to reate sub harmoni s. Invert this idea and raise the range of os illator 2
and find organ and other harmoni s whi h reate texture and interesting tones. The third os illator is added to
produ e a sub harmoni for the omplex waveform already reated, or an be set into LOW mode where
os illator 3 a ts as a modulation sour e for XMOD and PWM behavior. Or set them all the same, and then fine
tune ea h one into a hord.
The relationships between waveforms, range, and tuning alone an be ome fully engaging. Subtle hanges
produ e huge differen es in how the waveforms relate to one another and what inevitably omes out the
speakers. A thoughtful exploration of this se tion, taking your time, and repeating ideas an result in a superb
self-edu ation in the basi s of analog synthesis.
OSCILLATOR 1 & 2
RANGE
Sets the overall frequen y range of the Os illator’s tuning from LO, 32’, 16’, 8’, 4’ and 2’
TUNE/FINE
Tunes Os illator. Fine is the relative tuning of Os illator 2’s pit h in relation to Os illator 1. With analog
equipment tuning is important. Sometimes setting the TUNE pot to 12 o’ lo k doesn’t a tually mean that you are
in tune.
While there is an auto tuning feature on the SE-02 and the nature of modern ele troni s is more stable than
vintage analog, remember that the SE-02 is still an analog synthesizer and it’s always a good idea to allow them
to warm up before tuning, and needing to at least verify the tuning before beginning to play.
WAVEFORM
This is the waveform sele tor for Os illator 1 & 2 (respe tively.)
Choose between TRIANGLE, NARROW TRIANGLE ( omewhere between a triangle wave and a aw wave,
OSC 1 & 2 only), SAWTOOTH, SQUARE WAVE, PULSE WAVE 1 (wide,) and PULSE WAVE 2 (narrow.)
Experiment: With only OSCILLATOR 1 turned up in the mixer, and the filter open enough to hear what you’re
doing, swit h between the waves and listen to what they sound like. TRIANGLE is deep and pretty, SAW is sharp
and a little gritty, SQUARE is big and beautiful. Now swit h the range around - listen to a very high SAW, and
he k out a very low PULSE. These are the building blo ks of all sounds. Get a feel for how to reate them, and
what they’re alled.
SYNC SWITCH
This swit h engages and disengages os illator syn . In an analog synth, waveforms an report in and out of
phase. This means that waveforms start, and unfold over time differently. Syn is how we for e these waveforms
to play together at the same time. The syn swit h will for e Os illator 2 to return to the beginning of it’s y le
(start again) whenever the master waveform starts again. This puts the waveform into a mandatory
syn hronization with the wave y le of os illator 1.
Page 10 of 35 Manual V1.03 for firmware V1.11

Experiment: Set Os illator 1 and 2 to playba k sawtooth waveforms. Adjust the tuning of OSC 2 until it feels
interesting to you. Now engage syn . What’s happened to the sound? Disengage syn . Listen again. Sometimes
you want syn for effe t, other times you need syn for stability. Sometimes you really don’t want syn at all.
OSCILLATOR 3
RANGE
Sets the overall frequen y range of the Os illator’s tuning from LO, 32’, 16’, 8’, 4’ and 2’
FINE
Tunes Os illator 3’s pit h relative to the tuning of Os illator 1.
WAVEFORM
This is the waveform sele tor for Os illator 3.
Choose between TRIANGLE, REVERSE SAWTOOTH (OSC 3 only), SAWTOOTH, SQUARE WAVE, PULSE WAVE
1 (wide,) and PULSE WAVE 2 (narrow.)
ENV-1 KNOB
This knob adjusts the amount of modulation is applied from the filter envelope to the frequency of O cillator 2.
At 12 o’ lo k the result is nil. Rotating lo kwise results in a positive modulation, and ounter lo kwise results in
a negative modulation. Using frequen y modulation with the Os illators an seem ounter intuitive to those just
learning about analog synthesizers. Why would we want the sound to go in and out of tune? Try turning this up a
bit, and then adjusting the filter envelope. Turn things up pretty far. Sometimes the effe t is a gentle wave of
vibrato, and other times it’s just madness. Explore. Don’t be afraid to make some noise.
KEYBOARD SWITCH
This swit h tuns on and off keyboard tracking for O cillator 3. When keyboard tra king is disengaged, OSC3
works as an independent os illator. This is interesting when using OSC 3 as a modulation sour e, so the
modulation an do it’s own thing. It’s also interesting to drone out OSC 3 without key tra king as a juxtaposition
with tra ked notes from OSC 1 & 2.
XMOD SWITCH
This is the sele tor swit h for assigning whi h XMOD setting ( ross modulation) will be effe ted by the mod wheel.
A- OSC 2 Modulates the FILTER cutoff frequency
B- OSC 3 Modulates the waveform of OSC 2
C- OSC 3 Modulate the pul e width of OSC 1 & 2 (whi h only works if you’ve sele ted a square or pulse wave
for OSC 1 and 2 - otherwise it won’t do anything.)
IMPORTANT NOTES FOR VERSION 1.11
When LO range mode is sele ted for OSC 2, no CV is applied to the os illator; think OSC 3 KYBD swit h (and
the Minimoog). OSC 2 FINE now be omes a very aggressive oarse tune—makes for feral XMOD
experimentation. No fa tory pat hes were to harmed in the swit h to the new stati OSC 2 LO mode/FINE tune
reversal, so we opted for the opening up of CV fun tionality. However, if LO is a OSC 2 setting on any of your
USER pat hes, tuning adjustments will have to be made. Thanks for understanding in advan e.
Page 11 of 35 Manual V1.03 for firmware V1.11

XMOD
The XMOD se tion is were you sele t how ross modulation will be applied. Cross Modulation is des ribed as
XMOD (the X is a ross, and MOD is short for modulation) and also frequen y modulation. Frequen y
modulation is a vital omponent to analog sound design, and voltage ontrol. It’s easy to turn any ross
modulation knob and on lude that it’s a sort of razy freak-out. But in measured and intentional amounts,
XMOD an turn a simple pulse wave into a metalli ping, or a taught drum skin.
O2-FILTER
The O2-FILTER knob allows OSC 2 to modulate the cutoff frequency of the filter. This means that when you
rotate the O2-FILTER knob, the frequen y of the filter for the SE-02 will begin to modulate to the wave shape of
OSC 2.
Experiment: Turn down the volume of OSC 2 and 3. Lower the filter to reate a deep, moody sound. Set the
Waveform of OSC 2 to sine, and set the range to LO. Turn the O2-FILTER knob and listen to the wave shape of
OSC 2 begin to modulate the filter frequen y.
O3-O2
The O3-FILTER knob allows OSC 3 to modulate the waveform of OSC 2. This means that the waveform of
OSC 2 is hanged by the waveform of OSC 3 and this makes for some razy audio hooliganism. If the filter an
be modulated by OSC 2, and the shape of OSC 2 an modulate the waveform of OSC 2 then the ramifi ations
of this, and the impa t on the sound an be very ex iting.
O3-PW1,2
The O3-PW 1 and 2 knob allows OSC 3 to modulate the pul e width of OSC 1 and OSC 2. In essen e this is
how PWM (pulse width modulation) is a hieved in the SE-02. PWM is a wonderful way to animate the width of
the pulse waveform. If you haven’t et the waveform of o cillator 1 or 2 to PULSE/SQUARE then thi won’t
have any effect on the output.
Experiment: Set OSC 1 to make a SQUARE wave. Turn off the other sounds. Play a few notes and adjust the
filter and envelope to make a sound you really like. Set OSC 3 to LO range, and a rising SAW waveform. Now
slowly in rease the level of O3-PW knob and listen to what happens to the texture of the sound. Do you hear a
differen e? Go further and turn up OSC 2 and set it to a SQUARE waveform, and tune it to very lose to unison
with OSC 1, but not quite. Now rotate the O3-PW knob again and listen to the pulse width begin to modulate to
the wave shape of OSC 3. Pretty ool, right?

MIXER
This is the se tion where the outputs of OSCILLATOR 1, 2, 3 and NOISE are established and mixed in relation to one
another. There is also a FEEDBACK knob whi h adjusts how mu h of the SE-02 output is returned to the input of the
FILTER se tion.
OSC-1, OSC-2, & OSC-3
Adjust the output level of ea h os illator, and mix them together. For a pure noise output first turn up the noise
level, and then turn down the knobs for OSC 1, 2 and 3. Level mixing an help to shape and reate interesting
sounds as a pra ti e on its own. Blending a SQUARE wave into two SAWTOOTH waves an have an interesting
result in and of itself with and without additional modulation.
FEEDBACK
Adjusts the amount of the SE-02’s output ent back to filter input (ex ept for the DELAY) This hange the nature
of the sound radi ally.
Experiment: For a lose look at how FEEDBACK shapes sound, try turning off the volume of OSC 2 and OSC 3
and listen only to OSC 1. Now in rease the FEEDBACK level and listen to what happens to the sound.
NOISE
Adjust the volume of the noise os illator. Noise is a wonderful addition to the texture of a sound.
Experiment: Turn off OSC 1, 2 and 3. Listen to the NOISE. Shape the NOISE with the envelope and filter. Open
the release and listen to the slow de ay. Rotate the ATTACK knobs and listen to the slow rise of the NOISE.
Shape this into o ean waves, or the distant sound of some sand storm. Get into it. Add this texture to an
os illator’s wave.

FILTER/ENVELOPES
FILTER
These settings determine the brightness and thi kness of the sound. Here you an also spe ify the time- varying
hange (filter envelope) for the filter and the time-varying hange (amp envelope) for the volume. The filter is a
24dB/ o tave ladder design and again has a very similar layout when ompared to a lassi analog mono synth
filter se tion, though there are some additional ontrols like a ontour inverting swit h, restart on note press and
an option to trigger the amp with a gate or the LFO. The envelopes are really snappy and just like on the lassi
analog synths, you get an ADS envelope with swit hes to enable release ontrol with the de ay knob.
CUTOFF
Adju t the filter cutoff frequency. Clo kwise lowers the frequen y down to nominal, and ounter lo kwise
opens the filter ompletely.
EMPHASIS
Boo t the region near the filter cutoff frequency. Higher values produ e greater boost, reating a
distin tively “synthesizer-like” hara ter. This is essentially the re onance fun tion found on most filters, where
the moving edge of the utoff frequen y is exaggerated as EMPHASIS is in reased until self os illation is
a omplished.
KEY TRACK [1/3] [2/3]
Spe ify how the filter cutoff frequency change in re pon e to the pitch that is played on the keyboard.
[1/3]:The filter utoff frequen y hanges by 1/3 of the pit h hange.
[2/3]:The filter utoff frequen y hanges by 2/3 of the pit h hange.
If both swit hes are on, the filter utoff frequen y hanges by the same amount as the hange in keyboard pit h.
CONTOUR
Adju t the depth of change produced by the pecified envelope etting . This is an effe t similar to adding
a gate pulse to the filter, and the CONTOUR attenuator ontrols the amount that the filter envelope will impa t the
frequen y of the filter.
Experiment:A great way to understand this knob is to set the filter frequen y nearly to off, and play a series of
notes, or a sequen e. Now rotate the CONTOUR knob lo kwise slowly, and listen to the introdu tion of the
envelope and understand how an envelope effe ts filter frequen y.
MTRIG
If thi i on, the filter envelope re tart each time you pre a key. That means that if you swit h MTRIG on
then with ea h key played, the filter envelope will re trigger. With the MTRIG swit hed off, the filter envelope will
not be re triggered, but the envelope shape will be ompleted before the next key will trigger it again from the
beginning.

NORM/INVERT
Specifie the polarity of the envelope that i controlled by the CONTOUR knob. If this is set to “INVERT,”
the polarity is inverted. This is a very handy way of immediately transforming a sound just by effe tively “flipping”
the envelope.
Experiment:Create a slow atta k sound that you like. Now invert the envelope with the swit h. Listen to
what happens to the sound. Pretty ool, right?
ENVELOPES
An envelope is a entral method of shaping the sound of a synthesizer. Atta k, de ay, sustain and release are
the 4 main attributes of an envelope. Envelopes an ontrol volume, filter, and other aspe ts of audio, and
voltage.
Triggered by a gate pulse/key/note on the envelope is then fired and will move through its stages until it is
either done, or re triggered by another gate or key.
Atta k is the time the envelope takes to rise from silen e to full volume.
De ay is the time the envelope takes to fall from full volume to the sustain level.
Sustain is the time the envelope takes to drop from the sustain level to the release
level. Release is the time the envelope takes to fall from the release level to silen e.
FILTER ENVELOPE
ATTACK
Spe ifies the time (atta k time) from when the key is pressed until the utoff frequen y rea hes the maximum level.
DECAY
Spe ifies the time (de ay time) from when the utoff frequen y rea hes the maximum level until it de reases to
the sustain level.
SUSTAIN
Spe ifies the level (sustain level) that is held after the atta k time and de ay time have elapsed until the
key is released.

AMPLIFIER ENVELOPE
ATTACK
Spe ifies the time (atta k time) from when the key is pressed until the utoff frequen y rea hes the maximum level.
DECAY
Spe ifies the time (de ay time) from when the utoff frequen y rea hes the maximum level until it de reases to
the sustain level.
SUSTAIN
Spe ifies the level (sustain level) that is held after the atta k time and de ay time have elapsed until the key is
released.
GATE LED
Lit while a note is sounding, or gate is present.
RELEASE
Spe ifies whether the setting of the amp envelope [DECAY] knob is applied to the release time (the time from
when the key is released until the volume de ays to zero).
1, 2: Applied to both the filter and amp envelope.
2: Applied only to the amp envelope.
Off: No release, sound ut immediately.
LFO/GATE
Spe ifies the signal that ontrols the amp envelope.
LFO: The LFO ontrols the amp envelope.
GATE: The Note or Gate ontrols the amp envelope.

LFO
LFO is an a ronym for Low Frequen y Os illator. The frequen y of the modulation sour e hanges so slowly
that if fun tions as an influen e over volume, filter frequen y, and other non audio rate aspe ts of voltage
ontrol. The SE-02 offers LFO ontrol over the filter, the pit h and the volume of its output. Here you an
reate y li hange (modulation) in the sound by applying vibrato (pit h modulation) or tremolo (volume
modulation).
RATE
Adju t the LFO frequency. This is how slow or how fast the LFO hanges.
Experiment: Choose a sound you like. Now turn the FILTER knob of the LFO se tion up to 12 o’ lo k. Adjust the
RATE of the LFO and listen to the hanges. Adjust the main FILTER frequen y and see how the LFO effe ts the
relationship between the filter and low frequen y os illator.
WAVE
These are the wave hape whi h the LFO is able to take.
SAMPLE & HOLD
SINE
TRIANGLE
SAWTOOTH
REVERSE SAWTOOTH
SQUARE 1
SQUARE 2 (pulse Wide)
SQUARE 3 (pulse Narrow)
RANDOM
OSC
Adju t the depth to which the LFO affect the o cillator. This will apply an LFO to the pit h of the Os illator
se tion. Full ounter lo kwise will turn this effe t ompletely off. As you rotate the knob lo kwise the effe t of the
LFO on the os illator se tion in reases.
FILTER
Adju t the depth to which the LFO affect the filter. As demonstrated in the RATE experiment, this is where you
set the amount whi h the LFO will apply to the filter frequen y. Counter lo kwise will turn the LFO filter relationship off
ompletely. Rotating the LFO FILTER knob lo kwise will in rease the effe t.

MWHL
Select the modulator that i a igned to the LFO of the WHL MIX knob, and spe ifies the depth of the effe t.
F: The effe t is applied strongly.
H: The effe t is applied weakly.
OFF: No effe t is applied.
MODE
Spe ifies the LFO’s operating mode.
1X: The LFO applies only on e.
KEY: The LFO starts at note-on.
FREE: The LFO applies always.
SYNC
Sele ts whether LFO and DELAY are syn hronized with MIDI lo k.
Ø: Not syn hronized.
L: Only the LFO is syn hronized to MIDI lo k.
D: Only the DELAY is syn hronized to MIDI lo k.
LD: Both LFO and DELAY are syn hronized to MIDI lo k.
PWM LFO
Sin e version 1.10, an other LFO have been added to SE-02. It allows to modulates pulse width of the 3 os illators,
using a triangle Wave This LFO applies only on os illator whose sele ted waveform is SQUARE WAVE, PULSE
WAVE 1 (wide,) or PULSE WAVE 2 (narrow).
There a 2 parameters to ajust this LFO, a essible from pat h Setup menu ( [COMP] + [PLAY] )
[7] LFO PWM RANGE 0-127
[8] LFO PWM DEPTH 0-127
Those parameters are save with other pat h settings while write a pat h to user memory.

DELAY
This se tion is where the settings for the delay are made.
TIME
Adjusts the delay time.
NOTE:the timing of the delay will hange depending on the syn settings in the LFO se tion.
REGEN
Sets the number of repeats the delay reports. Setting this to full ounter lo kwise will produ e minimal
repeats. Clo kwise rotation will in rease the number of repeats until a ontinuous report.
AMOUNT
This is the volume ontrol for the DELAY. Full ounter lo kwise is essentially turning off the delay. As the
knob rotates lo kwise, the volume of the DELAY in reases to full volume.

[8] PWM LFO DEPTH 0-127 Adjusts the depth of the PWM LFO.(Added in V1.10)
[9] PATCH CLEAR Allow to lear a pat h
[15] CV FINE TUNE 0-255 Finely adjusts the pit h relative to the voltage that is input to the
CV INPUT ja k. (Added in V1.04)
[16] CV KEY FOLLOW 0-255 Adjusts the width of pit h hange relative to the voltage that is
input to the CV INPUT ja k. (Added in V1.04)
IMPORTANT NOTES:
PWM LFO: This dedi ated LFO is a triangle wave that modulates the pulse width of all 3
os illators (OSC 1–3). If a waveform other than pulse wave is sele ted, modulation is not applied.
Adjusting the CV INPUT ja k’s key follow setting will ause the tuning to hange slightly. For this
reason, you should adjust key follow first, and then use fine tune to spe ify the overall pit h. There
is no need to exe ute the Write operation. CV Fine Tune and CV Key Follow are saved as settings
for the entire system.
