201 Pocket Piano

$375.00 ($345 'b' stock)



At the heart of the 201 are six sound engines providing a wide range of sonic texture. Use the shift key to select an engine. There is a little bit of everything: chiptune style waveforms, analog style filters, drum samples, realistic physical instrument models, and even a human vocal synthesizer. Use the three center control knobs to further explore the sounds. Dial in the right amount of sustain, or adjust the tone. Or turn the 'surprise' knob if you are brave!


Play directly on the keyboard or turn on one of the pattern generators. From simple octave arpeggiation to randomizing polyphonic patterns you will be inspired by the notes coming out of the 201! Use the first control knob to set the pattern's tempo.
The pattern generators also work great for creating drum beats using the drum samples!


If you like the way something sounds, recording it is just a button press away! There is a handy metronome that you can play/record along with. When the sequence is playing back you can endlessly change the pattern and synth engine. When you get it just right, hit the save button. You can save 'unlimited' sequences (well... not really unlimited, but many thousands).Then recall saved sequences easily using the navigation buttons.


The 201 wants to be friends with all your other gear! It works great with guitar effects pedals and amps. With MIDI in and out you can control other synthesizers with the 201, or the other way around. A USB-C connector lets you easily move files on and off the instrument.  

Open Source

Critter & Guitari is committed to making musical electronics that are open platforms. Like our Organelle and EYESY instruments, the 201 is built entirely with Open Source software.
nside, the 201 uses a combination of Pure Data and Faust musical programming environments. Users are invited to modify or create new sound engines!
