"Using a synthesizer Arduino shield from Critter and Guitari (http://www.critterandguitari.com/), I constructed this enclosure so I could use this unique keyboard on my upcoming tour."

"A PocketPiano from http://www.critterandguitari.com/
and one Arduino. The first one soldered together from the kit I got it in then it's connected to the Arduino which is loaded with a small program I wrote. The program is creates a square pulse whose pulsewidth can be modulated by one of the knobs. Another of the knobs are controlling the very simple glide algorithm.

Much fun to be had!

Note the following auction does not mention Critter & Guitari, but the Pocket Piano kit below takes you to a page with the second video above.  I discovered the top video searching for more info.  I'm curious how this compares to the final released and enclosed Critter & Guitari Pocket Piano we are all familiar with.  Note the number of button keys are different.

The Arduino Pocket Piano got a mention back in May of 2008.

"This is the original Pocket Piano Kit fully assembled. This is an open source stand alone synthesizer, that you program with the Arduino software That can be obtained here..."

Here is more info:
Pocket Piano kit – This is a board for making the Arduino into a portable stand alone music synthesizer. It plugs directly into the Arduino board and provides 25 multiplexed keys (2 full octaves), 4 pots, status LED, reset switch, digital to analog converter IC, and a RCA audio jack. The Arduino board with its powerful AVR processor is more than adequate for a wide range of sound synthesis techniques. We have experimented with simple additive / wave-table synthesis, frequency modulation, ring modulation, sampling, polyphony, various arpeggiators. The whole thing can be powered over the Arduino’s USB port for convenient experimenting. Arduino Diecimila is included. The board is designed to mount easily to 1/8″ panel material, and 1/2″ round keys can be made out of wood or plastic. Features include -

· 25 keys and multiplexer circuitry
· 4 potentiometers, 1 controls output level
· Microchip MCP4921 12 bit SPI DAC
· Passive low pass output filter"
