Introducing the P6

A DIY virtual analog polyphonic synthesizer | chorder | arp


With 2 oscillators, 1 sub-oscillator, a switchable 4-pole lowpass and multimode 2-pole 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.

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 matte black (think fingerprint resistant) laser cut enclosure, the P6 is a small-in-size but powerful-in-sound addition to your music rig.

UPDATE July, 8th 2014

A new firmware will be available shortly, mainly featuring FXs and other improvements in the matrix (more patchcords/sources/destinations). This new firmware will be FREE (like all our firmware upgrades) and can be installed without opening the case thanks to the mini USB port. Preview:

See below for other sounds recorded with the current firmware.

New case design will be in stock in a few days is now in stock in the store.

Sounds demos

Here are some sound samples recorded during the development of the P6′s firmware.

Samples are added on a regular basis.



Polyphony: 6 voices
Multitimbrality: 1


OSC1 with continuously variable shape
Sub with switchable shape (sinus, triangle, saw, square, pulse 25%, pulse 10%)
OSC2 (like Osc1), syncable to OSC1
OSC1 and OSC2 can be ring modulated (separate input in mixer)
Pink noise


The filter is switchable between a classic 4-pole ladder filter and 2-pole state variable filter (that offers LP, BP and HP).
The filter self resonates and can be tracked by the keyboard (Off, 25%, 50%, 75%, 100%)


3 analog-shaped envelopes (ADSR)
ENV1 routed to AMP, ENV2 to Filter cutoff

3 switchable shape LFO’s with delay and BPM sync (sinus, triangle, square, s&h, random)
LFO1 routed to OSC1 shape, LFO2 to Filter cutoff

In addition to these fixed modulation options, a modulation matrix with 4 patch cords is available.


ARP with Up, Down, Up&down and Random modes
Up to 4 octaves transposition
Speed, Gate settings and Latch mode


Adds up to 3 note 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)


Stereoizer FX with level control


Audio outs (L/R) on 1/4″ jacks
9V DC input (center positive, 300mA min.)
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
Bourns encoders
ALPS stereo volume pot

I’m sold, how do I get one?

The P6 is available as a 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).
UPDATE: the kit is now available as standard with the CMS DAC already soldered and ready to use, making the P6 kit 100% thru-hole.
