Intro
e Multiwave Mega is a monophonic
wavetable-based guitar synthesizer
with an analog resonant lowpass lter
* Two oscillators with several waveshapes
* One oscillator that can be detuned
* Resonant lowpass lter with envelopes
* Sustain mode (aka “drone mode”)
* LFO’s for both the oscillators and lter
* OLED oscilloscope*
* only avaliable on the fully assembled version
KEY FEATURES
e two oscillators will be reered to here as the primary and
the secondary oscillator. When rst powering up you will only
hear the primary oscillator by default.
e secondary oscillator needs to be activated using the
Blend function - see page 6

Buttons
e Mega has four push buttons. In this manual we will
refer to them as button 1 through 4 (from le to right).
Each push button has three dierent functions
* Normal press - short press
* Long press - press and hold for at least 500ms
* Shi press - press and hold button 1 (marked “Shi”),
then press one of the other buttons
e LED will blink two times to indicate a long press,
and it will blink 3 times fast when doing a shi press.
is gives a nice visual indication of the button response.

e row under the button describe the Shi press functions.
e top row describe the normal press functions.
the second row describe the long press functions.
OVERVIEW

WAVESHAPE
normal press
is will cycle through all the waveshapes
for the primary oscillator.
1. Sawtooth
2. Square
3. Pulse
4. Narrow pulse
5. Bell *
6. Sine
7. Noise **
* e “Bell” waveshape is an FM inspired shape that blends
sinewaves at dierent frequencies, to produce a bell-like sound.
** e noise is technically still a sinewave, but it starts from a
random postition within the wavetable to produce noise.

is will save the current waveshape as the waveshape for
the secondary oscillator.
See the Blend details on button 2 (page 6)
SELECT
long press
Press and hold this button, then press one of the other
buttons to activate their respective shi functions.
Shi functions are described under the buttons
on the same row as the “Shi” marking
SHIFT

DETUNE
normal press
is will detune the primary oscillator to a higher pitch.
It will toggle through 6 dierent steps. e rst step is just
slightly detuned, followed by 5 other musical intervals.
Note that only the primary oscillator will detune, so when the
blend is activated this will create a layered sounds between
the two oscillators, almost like playing chords. e rst detune
setting is just slightly out of tune so it will create a cool
phasey modulating sound.

7.
BLEND
long press
is will activate the secondary oscillator
blended together with the primary oscillator.
e waveshape of the secondary oscillator can
be selected by doing a long press of button 1.
is way you can blend any* of the waveshapes
together using button 1 (toggle & select).
* except the noise (waveshape 7) that can only be
used with the primary oscillator.
OCTAVE
shi press
is will transpose the secondary oscillator
down one octave, so it can basically become a
"sub oscillator" to fatten up the tone.

Button 3

8.
ENVELOPE
normal press
When the VCF is activated (by doing a long press), this will
toggle through three dierent envelope shapes used to
sweep the lter cuto.
1. fast attack/slow release
2. slow attack/slow release
3. slow attack/fast release
If the VCF isn't activated, normal presses to this
button does nothing.
