Dual Mini Sequencer Operating Instructions
Playing Sequences
Push RUN to start playing a sequence. The RUN LED will light to tell you that you are in Run
mode. Push it again to pause. The sequencer steps can be programmed while paused.
Push RESET to stop the sequence, go to step 1, and enter Ready mode. The STEP LED will blink
to let you know that you are in Ready mode. This means that when you press RUN again, the
sequencer will play step 1 on the next clock pulse instead of skipping it and going to step 2.

If you want to start on a different step, you can use the STEP LEFT and STEP RIGHT buttons to
pick a different one.
While in Ready mode, you can use the note/keyboard buttons to manually play tunes without
messing up the sequence you have stored in memory. Gate timing will follow your button
presses.
Programming
Programming is done while the STEP LED is steady (not Ready mode) and the sequencer is not
running. You can enter Program mode by pressing RESET a second time, or pausing a sequence
with the RUN button. Use the STEP LEFT and STEP RIGHT buttons to pick which step you want to
program, then press the note you want that step to play. The new note is automatically stored
in non-volatile memory.
Remember about the STEP LED:
•Blinky = Ready Mode = Will start on selected step = Can play keyboard live
•Steady = Program = Any notes you push will get saved in that step
The sequencer covers 5 octaves, so you can use the OCTAVE UP and OCTAVE DOWN buttons to
transpose the keyboard up and down. The OCTAVE UP and OCTAVE DOWN LEDs will tell you
which octave the keyboard is currently set to:
•Down Steady: -2 Octaves (0V to <1V)
•Down Flickery: -1 Octave (1V to <2V)
•Both Off: Middle Octave (2V to <3V)
•Up Flickery: +1 Octave (3V to <4V)
•Up Steady: +2 Octaves (4V to <5V)
In addition to standard notes, you can also program a REST, LOOP or ACC into a step:
•REST: Instead of containing a note, a REST step holds the previous note and doesn’t fire
the gate.
•LOOP: Instead of containing a note, as soon as the running sequencer hits a LOOP step
it is immediately sent back to step 1. You can use this to create any length sequence you
want. For example, if you only want steps 1-13 in your sequence, you would make step
14 a LOOP step.
•ACC: In addition to a note, the ACC output can be programmed into any step. Use the
ACC button to toggle it on and off.

Clock
While the sequencers are much more useful when driven by an external clock, they do include
internal clocks. They are active when the sequencers are first powered on, but are disabled
when an external clock pulse is received. To reactivate the internal clock, you can press and
hold the RESET button for about 2 seconds (this soft-resets the sequencer).
To adjust the tempo, use the STEP buttons while a sequencer is running.
You can use the CLK IN jacks to provide an external clock signal to the sequencers. The top CLK
IN jack is cascaded through the bottom one, so you can run both sequencers from a single
clock. Connecting a different clock signal to the bottom CLK IN jack makes them each run from
their own separate clocks.
Expansion
The XP IN and XP OUT jacks can be used to daisy-chain sequencers together:
•XP IN: A gate pulse into this jack resets the sequencer to step 1. It also puts it in run
mode if it’s not already.
•XP OUT: Sends a gate pulse when a running sequence drops off the end (goes past 16
or hits a Loop step).
The switch contact in the XP IN jack is normalled to the XP OUT signal, so with nothing plugged
into either jack, each sequencer will loop by itself once it goes past the last step of a sequence.
This is exactly the same as running a patch cord between XP OUT and XP IN on a single
sequencer.
You can connect a cable to the XP OUT jack without breaking the internal looping. This gives
you an “end-of-sequence” gate signal that you can send to other modules, or use to start other
sequencers.
Connecting a cable to the XP IN jack breaks the internal looping, so when the sequencer gets to
the end of the sequence it goes into Ready mode rather than continuing to run.
Run 2 sequencers in series: To make a 32-step sequence, connect XP OUT of Sequencer 1 to
XP IN of Sequencer 2, and XP OUT of Sequencer 2 t0 XP IN of Sequencer 1.

Of course, if you have more sequencers (or even other devices), you can daisy-chain as many as
you want.
Calibration
You can use the trim pot next to each CV OUT jack to calibrate the sequencers to 1 volt per
octave.
Procedure:
•Connect a voltmeter to the CV OUT jack of the sequencer you want to calibrate
•Press RESET to make sure the sequencer is in Ready or Program mode (either will work)
•Press the OCTAVE UP button a few times to set the keyboard to the highest octave
(OCTAVE UP LED on steady)
•Press the NOTE C button
•Adjust the trim pot until the meter reads as close to 4.000V as you can get it
•Check the C notes on the lower octaves by pressing the OCTAVE DOWN then NOTE C
buttons. Each one should be an even voltage. If not, adjust the trim pot until they are as
close as possible

C4 (Hi
g
hest Octave) = 4.000V
C3 (Hi
g
her Octave) = 3.000V
C2 (Middle Octave) = 2.000V
C1 (Lower Octave) = 1.000V
C0 (Lowest Octave) = 0.000V
The outputs of the sequencer are buffered, so they should maintain their voltages even when
loaded down by another module. You may find, however, that the standard calibration doesn’t
work with certain modules. In this case, you can use the trim pot to adjust the calibration so
that it is correct for your module.

Version 2
Instructions beyond this point refer to new features found in version 2 of the sequencer
firmware. You can tell if you have v2 by watching the sequencer’s boot light show; after it lights
each row of LEDs sequentially, it will light the step 2 LED then the step 10 LED (for v2.0) before
the clock LED starts blinking. If it doesn’t light any LEDs during this time then you have v1
firmware.
Song/Sequence selection mode
Press and release both the OCTAVE UP and OCTAVE DOWN buttons at the same time. This
changes the note key display to SONG/SEQUENCE SELECT mode. Pressing this button
combination again takes you back to the normal note select mode.
Selecting a Sequence
If the entire row of white keys is lit while displaying SONG/SEQUENCE SELECT, you are in
SEQUENCE mode. The selected sequence will play to the end then loop back to the beginning.
The sequencer has 7 sequence memories available for you to choose from. The steady LED
indicates the currently selected sequence. To select a different sequence, press the white note
key corresponding to the sequence you want to select. If the sequencer is running, the newly-
selected sequence LED will flash until the sequencer reaches the end of the current sequence
(or on the next clock; see CHANGE ON CLOCK mode), then it will switch to the new sequence.
Another way to select a sequence, even while the display is in another mode, is to hold down
the PROG/RESET button then press the desired sequence button. The display will automatically
change to SONG/SEQUENCE SELECT mode.

Selecting a Song
If the entire row of black keys is lit while displaying SONG/SEQUENCE SELECT, you are in SONG
mode.
The sequencer has 5 song memories available, which can be used to string together up to 16
sequences in any order. Each song step contains one sequence. When running and the current
sequence has completed, the sequencer will advance to the next song step and play the
sequence it contains.
To select a song (and switch to SONG mode), press the black not key that corresponds to the
song you want to play. If the sequencer is running, the newly-selected song LED will flash until
the sequencer reaches the end of all the sequences in the current song (or on the next clock;
see CHANGE ON CLOCK mode), then it will switch to the new song.
Another way to select a song, even while the display is in another mode, is to hold down the
PROG/RESET button then press the desired song button. The display will automatically change
to SONG/SEQUENCE SELECT mode.
Programming a Sequence
Programming a sequence hasn’t changed much since v1. Whichever sequence you have
selected is the one you are modifying when you enter PROGRAM mode (steady STEP LED) (See
above for basics). There are, however, a few additional options…
SLUR
Rests still work like in v1; when the sequencer gets to a REST step, it keeps the CV OUT the same
and doesn’t fire the gate. You can also make a step a SLUR, where it changes the CV OUT to a
new note but still doesn’t fire the gate.

To program a SLUR on a step, hold down the REST button, then press the desired NOTE button
for that step. Both the REST and NOTE LEDs will light.
Gate Timing
When you first program a note into a step, the gate timing is set to the default mode where the
gate follows the timing of the clock. V2 gives you 16 different gate timings to choose from:
•1- Normal/Follow
•2-1/4
•3- 1/3
•4- 1/2
•5- 2/3
•6- 3/4
•7- Full (almost- gate will still drop briefly before next step)
•8- Second 1/4
•9- Third 1/4
•10- Fourth 1/4
•11- Second 1/3
•12- Third 1/3
•13- Second 1/2
•14- Double (ratchet!)
•15- Triple (ratchet!)
•16- Quadruple (ratchet!)
All the gate timing modes besides 1 work by dividing up the incoming clock signal then
calculating the needed timings. This works best with steady clocks. If you are wanting to make
drastic rapid changes to the incoming clock rate then you will probably get the best gate timing
results from using mode 1.
To choose one of the above gate timings while programming a step, press the desired note
multiple times. Every time you press the same note, the next gate timing will be selected. The
current timing number will be shown briefly on the STEP LEDs every time a new one is
selected. The GATE OUT will also do its best to demo the current gate timing for you.
ACC
The ACC output can be programmed into each step as before, but now there are 3 on modes to
choose from:

•On (Stays on for entire duration of step and doesn’t drop before the next step)
•On w/ Drop (Stays on for most of step, but drops briefly before the next step)
•Gate Follow (Timing follows gate timing for the step)
When programming a step, each press of the ACC button cycles to the next mode. The ACC LED
will flash to let you know what mode you have set:
•On (LED stays on)
•On w/ Drop (LED flashes once then stays on)
•Gate Follow (LED flashes twice then stays on)
•Off (LED turns off)
Programming a Song
Each step in a song contains a sequence. To program sequences into song steps, first make
sure the keyboard display is in SONG/SEQUENCE SELECT mode (press OCTAVE UP and OCTAVE
DOWN at the same time if it’s not). Press one of the black keys to select the song you want to
work on.
Press PROG/RESET until the STEP LED is steady; you are now in program mode.
Press the white key that corresponds to the sequence you want to store in the current song
step. The white key LED corresponding to the selected step will light.
Press the STEP UP to advance to the next song step (or STEP DOWN to go back) and select the
desired sequence for that step. Continue to program sequences into steps until they’re all
programmed.
If you don’t want to use all 16 steps in your song, you can use the LOOP button to make the
step after the end of your song a LOOP step. For example, if you only want 4 sequences to play
in your song, program a LOOP into step 5. When running, the sequencer will bounce off of step
5 and loop back to the first step of the sequence programmed into the first step of your song.
Copying a Song or Sequence
When programming songs or sequences, sometimes you might want to copy an existing one so
you can modify it instead of starting over from scratch for each one. To do this, first make sure
the keyboard display is in SONG/SEQUENCE SELECT mode. Press and hold the song or
sequence you want to copy from, then press and hold the song or sequence you want to copy

to. Hold the two buttons for about 1 second; the note LEDs will flash to let you know when the
copy has been performed.
•The copy always goes from the FIRST -> SECOND button you press!
•You can’t copy songs to sequences or sequences to songs
Clearing a Song or Sequence
All the songs and sequences in the sequencer always exist, so generally if you want to wipe out
an existing song or sequence you can just modify them or program something new over the top
of them. If you do want to “clear” a memory, however, you can. Clearing a sequence sets all
the steps to the lowest note. Clearing a song sets all the steps to sequence 1.
To do this, first make sure the keyboard display is in SONG/SEQUENCE SELECT mode. Press
and hold the song or sequence you want to clear, then press and hold the RESET button. Hold
the buttons for about 1 second; the note LEDs will flash to let you know that the song or
sequence has been cleared.
Internal Clock
The internal clock works pretty much like before (see v1 section), but more speed choices have
been added and they have been more heavily concentrated in the “useful” range. Also, we
know what actual BPMs the speeds are now!
10 BPM 120 BPM 200 BPM 400 BPM
25 BPM 130 BPM 210 BPM 500 BPM
50 BPM 140 BPM 220 BPM 600 BPM
70 BPM 150 BPM 230 BPM 700 BPM
80 BPM 160 BPM 240 BPM 1000 BPM
90 BPM 170 BPM 250 BPM 2000 BPM
100 BPM 180 BPM 275 BPM 4000 BPM
110 BPM 190 BPM 300 BPM 8000 BPM

The internal clock uses the PIC microcontroller’s built-in oscillator for timing, so it may not be
super-accurate. We still recommend using an external clock if you’re doing something that is
timing-critical.
PROG/RESET Button
The RESET button now has an additional function (or rather a bunch of them). It is used in
conjunction with some of the other buttons on the sequencer to enable and disable various
modes (as indicated by the text in the white rectangles for more common functions).
AUTO ADVANCE
When this mode is enabled and you are programming a sequence, once you enter a NOTE or
REST or LOOP into a step, the sequencer will automatically advance to the next step. This lets
you just play your sequence into the sequencer without having to press STEP UP in between
each step, making initial programming of a sequence easier.
Note: Gate timing selection, SLURs, and ACC mode selection are not available in AUTO
ADVANCE mode. You can enter in the basic structure of your sequence then go back in normal
PROGRAM mode and tweak the timings, etc.
To enable or disable AUTO ADVANCE mode, hold down the PROG/RESET button and tap the
STEP DOWN/AUTO ADV button. The STEP 16 LED will blink twice when enabled and flicker
dimly when disabled.
Once enabled, AUTO ADVANCE mode stays on until the next time you put the sequencer in RUN
mode, at which time it will disable itself. That is unless you enable…
PERSISTENT AUTO ADVANCE MODE
To ensure that AUTO ADVANCE mode stays turned on until you manually turn it off (even if you
press RUN), enable PERSISTENT AUTO ADVANCE MODE by pressing and holding PROG/RESET,
pressing STEP DOWN/AUTO ADV, and holding both buttons for 1 second. The STEP 16 LED will
blink twice dimly when enabled and flicker once dimly when disabled.
LIVE TRANSPOSE

When this mode is enabled and the sequencer is running (and not displaying SONG/SEQUENCE
SELECT), You can use the note keys to temporarily transpose your entire sequence up or down.
Hold down the PROG/RESET button, then tap the LOOP/LIVE XPOSE button to cycle through the
different LIVE TRANSPOSE modes:
•On, root key at top of keyboard
•On, root key in center of keyboard
•On, root key at bottom of keyboard
•Off
The LOOP LED will flash twice for each ON mode, along with the selected root key. The LOOP
LED will flicker dimly when LIVE TRANSPOSE mode has been turned off.
While running in this mode, instead of the usual current-note display, the NOTE and OCTAVE
LEDs will display the status of your transposing:
•Steady NOTE LED = root key
•Blinking NOTE LED = currently selected transpose amount
•Dim/flickering NOTE LED = all the notes in between
If you press the root key (indicated by a steady NOTE LED), the transpose amount will be set to
0 and your sequence will play just as it’s programmed.
If you press a NOTE key above the root key, then the CV OUT will be transposed up by however
many steps the key you pressed is above the root key. For example, if the root key is the F in
the middle of the keyboard and you press the G key, then your sequence will be temporarily
transposed up 1 step (2 semitones). The LED corresponding to the key you selected will blink to
let you know at a glance how much you are transposing and in which direction. All the LEDs in
between the root key and your selected key will flicker dimly.
If you press a NOTE key that is below the root key, then the CV OUT will be transposed down by
however many steps the key you pressed is below the root key.
If you want to transpose farther than what is currently displayed on the keyboard, you can use
the OCTAVE UP and OCTAVE DOWN buttons to shift the keyboard octave. Select the octave you
want, then press the key for the amount you want to transpose. You can also instantly jump to
a transpose key in another octave (one up or one down) by holding one of the OCTAVE buttons
and pressing the desired key.
Note: You can’t transpose past the range of the CV output. For example, if you have a note in
your sequence that is the lowest C, then you try to transpose down from there, the output isn’t
going to get any lower. For maximum transposeability we recommend programming your
sequences in the middle octaves.

If you use the RUN button to pause the sequencer then start it again, whatever transpose
amount you set will be retained. If you press RESET to go back to the beginning of the
sequence then the transpose amount will be cleared.
There are a few other buttons that work in LIVE TRANSPOSE mode that might come in handy
during a live performance:
•REST: Makes the next step a REST (one time only)
•LOOP: Loops back to the beginning of the song or sequence on the next step (one time
only)
•ACC: Turns on ACC OUT on the next step (one time only)
LIVE EDIT
Normally when a sequence is running, the NOTE buttons don’t do anything. With LIVE EDIT
mode enabled, you can use the NOTE buttons to program your sequence on the fly.
To enable or disable LIVE EDIT mode, hold PROG/RESET down and tap the ACC button. The ACC
LED will blink twice for enabled and flicker dimly for disabled.
When the sequencer is running, pressing a NOTE button will program that note into the current
step. You can also program a REST or a LOOP during live editing.
Note: the changes you make using LIVE EDIT don’t actually get written to the sequencer’s non-
volatile memory until you pause/stop the sequencer. Don’t disconnect power while it’s running
or you’ll lose your changes! (This does not apply to using the normal PROGRAM mode; changes
are saved immediately.)
1X
1X mode is enabled by default, and is the way the v1 firmware worked.
Normally the sequencer sends a pulse from XP OUT to XP IN (the jacks are normalled) when it
falls off the end of a sequence and it’s time to loop. This is so you can daisy-chain to/from other
sequencers. If you plug something into XP IN that interrupts this signal, then the sequencer will
just pause when it gets to the end of a sequence.
In order for you to be able to use XP IN as a reset input without the need for an external gate
mixer, you can disable 1X mode. Hold PROG/RESET down and tap the RUN button. The RUN
LED will flicker dimly for disabled and blink twice for enabled.

With 1X disabled, the sequencer will loop internally at the end of a sequence (or song) without
needing to receive a gate pulse in XP IN. It will still respond to incoming pulses, however.
RUN/RESET
This is another mode you can enable for XP IN. In this mode, the sequencer starts when XP IN
goes high and resets when it goes low. You can use this mode to both start and stop the
sequencer, or start it from a step other than 1 (select your starting step with the buttons, then
send a gate pulse to XP IN).
To toggle this mode, press and hold PROG/RESET then RUN (just like for 1X mode), then hold
them for about 1 second. The clock LED will blink twice for enabled and flicker dimly for
disabled.
Note: If you enable this mode but don’t have anything plugged into the XP IN jack, the
sequencer won’t loop properly when it reaches the end of a sequence since XP OUT is cascaded
to XP IN (the XP pulse will just trigger a reset).
CLOCK OUT
You can set the sequencer to send the internal clock out the ACC jack. Press and hold
PROG/RESET, then ACC, then hold the button combination for 1 second. The ACC LED will blink
twice to let you know that CLOCK OUT is enabled and will flicker dimly when it has been
disabled.
ACC will no longer be sent out this jack, but it can still be programmed into sequences. The ACC
jack will still operate normally when using an external clock.
CHANGE ON CLOCK mode
Normally if the sequencer is running and you select a new song or sequence to play, it waits
until the current one has completed before switching to the new one. You can change this so
that the song or sequence is switched on the next clock by enabling CHANGE ON CLOCK mode.
To enable this mode, press and hold PROG/RESET, then STEP UP, then hold both buttons for 1
second. The STEP 15 LED will blink twice for enabled and flicker dimly for disabled.
