- Page 5 Buttons OVERVIEW 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,...
- Page 6 Button 1 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.
- Page 7 Button 1 SELECT long press is will save the current waveshape as the waveshape for the secondary oscillator. See the Blend details on button 2 (page 6) SHIFT 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 ”...
- Page 8 Button 2 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.
- Page 9 Button 2 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 &...
- Page 10 Button 3 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.
- Page 11 Button 3 VCF ON long press is will activate the VCF = Voltage Controlled Filter. e lter cuto is normally controlled by the "cuto /rate" knob. But with the VCF activated, the lter is insted controlled by an envelope that will sweep the lter cuto automatically, just like having an invisible robot turn the lter cuto knob for you, when hitting a note.
- Page 12 Button 3 VCF ON (cont.) In VCF mode, the lter is normally "closed", just like turning the cuto pot fully clockwise (full treble attenuation). When you hit a note and the threshold LED comes on, it will go through the attack portion of the envelope - the lter will open up and hold it open until the signal has dropped below the threshold (and the LED turns o again) - then it will go through the release portion of the...
- Page 13 Button 3 LFO ( lter) shi press is enables automatic repeats of the lter envelope, insted of being triggered by the guitar signal, basically turning it into an LFO = Low Frequency Oscillator. e rate is controlled by the cuto /rate knob, and the same selection of envelope shapes can still be toggled through with normal button presses.
- Page 14 Button 4 LFO SHAPE normal press When the LFO is on (by doing a long press), normal presses will toggle through 4 di erent waveshapes for the LFO. 1. Sinewave 2. Sawtooth 3. Ramp (inverted saw) 4. Pseudo random When the LFO is o , normal presses to this button does nothing.
- Page 15 Button 4 LFO ON long press is will turn on the LFO. is function is pretty quirky and wierd, but too fun to not include and can create some unexpected sounds... :) e LFO has two modes. In both modes it will respond very di erently depending on the oscillator waveshape.
- Page 16 Button 4 MODE shi press is will change the mode of the LFO to an alternative mode that does a more intense and harsher sounding frequency modulation with less amplitude modulation. One of my favourite settings is using this LFO mode together with the random wavshape, which will create what sounds like a random note sequencer.

- Page 18 Knobs THRESHOLD e threshold control sets the guitar signal trigger point. is is used for both the lter envelope and the sustain mode (see pages 10 and 17). It needs to be adjusted so that the threshold LED (next to the threshold pot) only lights up when you hit a note, and turn o as soon as the note starts to decay.
- Page 19 Sustain e Sustain footswitch e Multiwave Mega has a sample and hold feature that will sustain a note forever (aka “drone Mode”). is is enabled with the Sustain footswitch. When the sustain mode is enabled the LED (next to the toggle...

Page 20: Reshold
Sustain e SW MODE switch ere are two di erent sustain modes, depending on the position of this toggle switch. Down position - In this mode the footswitch will hold the note forever (basically bypassing the guitar input), until pressed again. Up position - In this mode the footswitch will enable guitar signal triggered sustain. -
Page 21: Tips
Tips Tracking To get the best sounds out of the Mega, keep in mind that it is a monophonic device. Strummig chords will not work. Play single notes and keep it clean. I recommend using the neck pickup on your guitar with the tone/treble rolled all the way down. -
Page 22: Quirks And Bugs
Quirks & bugs * A er doing certain shi presses, the rate pots for the VCF and LFO will sometimes become unresponsive and you will have a very slow rate. is is a known bug, but easily xed by simply pressing any button once to regain rate control. * When pressing Button 3, the lter will temporarily open. -
Page 23: Technobabble
Data TECHNOBABBLE e Multiwave Mega is a analog / digital hybrid. On the analog side with got the preamp, sample and hold and the resonant lowpass lter. On the digital side we have a microcontroller that handles the oscillators, lter control, the LFOs and the buttons. - Page 24 OLED THE TINY OSCILLOSCOPE e Fully assembled version of the Mega features a small 64x128 pixel monochrome oscilloscope that gives a nice visual feedback. e OLED and the related circuitry is not included or supported with the PCB/DIY kit, since it would make it harder to for people to build (having to make a square hole) and add an extra cost.

Page 25: Credits
Credits e Mega was created by me, Fredrik Lyxzén, during a period of 8 months, from around january to september 2019. I spent hundreds of hours of breadboarding and late night programming. Over the course of these months, the project has gone through several major changes and been redesigned from scratch twice. - Page 26 www.parasitstudio.se...
