A DIY 6-voice polyphonic synth | chorder | arp with 16-step pattern sequencer | FX’s
With 2 oscillators, 1 sub-oscillator, an 8-mode resonant filter, 3 envelopes and 3 LFOs per voice, the P6 is capable of producing a large array of classic analog-like sounds, pads, strings, brasses, organs, leads, basses, arpeggios, fx’s and even drum sounds. It’s also fun to play with is integrated chorder and arp pattern sequencer.
Thanks to the easy to use interface with 6 encoders and 9 buttons, you will find yourself creating sounds in no time.
Housed in a compact and stylish laser cut enclosure (several colors available), the P6 is a small-in-size but powerful-in-sound addition to your music rig.
NOW with enhanced V2 firmware and blue LCD screen with matching blue LEDs !!!
Thanks again for making such a fantastic and versatile instrument.
Finally completed the build today, works like a charm and sounds great.
Arrived this morning at 11:30 … 16:30 emits the first sounds! Finished at 17! Nice tool, good sound! Simple construction!
Le P6 est énorme de chez énorme, il sonne vraiment très bien c’est assez bluffant ! Au studio nous avons pas mal de diy et je suis prêt a faire le beta-testing du P12
I have just built the P6. Took me about 4 hours and 20 minutes. Very nice kit and easy to build, thanks to the very detailed instructions. Nice sounds too!
I received the P6 today and just finished the build. It was a very pleasant kit to build, also it looks really nice in the new design case, good work !
Finished my first build today! Sounds awesome
Just a quick one to say thanks for the kits. We’ve built two so far and they both look, work and sound great. You’re right about the yellow/green case – looks fantastic! The case is also a very good fit for the board/screen etc – very well designed.
Just finished mine, upgraded to 1.03 and now playing with it and having lots of fun! It sits next to my Shruti and that just fits on top of the battery compartment of the Casio PX-5s. Thanks Samuel, for the great service and the nice design.
I love this thing! keep up the excellent work!
What’s new in V2?
Check this video explaining the main differences with V1
Specs (Firmware V2)
Polyphony: 6 voices
Capable of 12 voices when polychained to a second unit
202 finely tuned presets
2 oscillators – 8 different algorithms each with a different variable shape
Sub with switchable shape (sinus, triangle, saw, square)
OSC1 and OSC2 can be ring modulated (separate input in mixer)
8 different filter types:
- 1-pole lowpass
- 2-pole lowpass
- 3-pole lowpass
- 4-pole lowpass
- 2- pole hipass
- 2-pole bandpass
The filter self resonates and can be tracked by the keyboard (Off, 25%, 50%, 75%, 100%)
Mixer inputs : osc1, osc2, sub, ring modulator, noice
Post voice mixer “VCA Drive” to adjust preset volume
Each voice can be panned independently
3 envelopes (ADSR) with optional reset at retrig
3 curves (p6 – the snappiest, exp, linear)
ENV1 routed to AMP, ENV2 to Filter cutoff, ENV3 to OSC2 shape
3 switchable shape LFO’s with delay, attack, phase control and BPM sync (sinus, triangle, sawtooth, square, s&h, random, 8-step sequence)
LFO1 routed to OSC1 shape, LFO2 to Filter cutoff
In addition to these fixed modulation options, a modulation matrix with 6 patch cords, 3 scalers and 1 lag operator is available.
ARP with Up, Triplet Up, Down, Triplet Down, Up&down, Random and As Played modes
Up to 4 octaves transposition
Can be used with a 16-step pattern sequencer to trigger different events
Adds up to 3 notes to the played note.
Allows chords to be played with one finger.
Key and scale settings
Choice of the added notes (From -1 octave to +2 octaves, in 7-note scale steps)

Mini-USB port (for firmware upgrades)
The P6 uses a 32-bit microcontroller with floating point support.
24-bit 192kHz DAC
Sample rate: 48kHz
2×24 characters LCD
ALPS stereo volume pot

I’m sold, how do I get one?
The P6 is available as a 100% thru-hole DIY kit including everything included to build it (pcb, components, cpu card, knobs, case, etc…), except the very common 9V DC adapter.
You will additionally need a soldering iron, some solder, basic soldering skills as well as the ability to follow simple but precise instructions (see the DIY soldering guide to check what’s involved).
