This is a portable synthesizer with keypad pitch control. The 16 keys play chromatically, so you get an octave plus 3 notes. It produces sound using a simple frequency modulation oscillator pair. The four knobs control volume, tuning (shifts the base pitch of the keypad up and down), harmonicity, and modulation-depth-waveform. The modulation-depth-waveform is a combo-control that varies the modulation depth and changes the waveform of the oscillators from sine to triangle.
Powered with a 9 volt battery, it is very loud. Also has a 1/4" switched output jack bypasses the speaker and allows the synth to be plugged into an external amplifier / effects.
The synthesizer also runs open source software, and is re-programmable for people interested in extending it or creating new sounds. It is a very similar design to our Arduino Pocket Piano Kit. Download source code.
A low note with the modulation knob being slowly turned.
Harmonicity and modulation depth turned way down for virbrato effect, and then increased for a thicker sound.
Here is a little mash up of the syntheszier recorded with a microphone. In many of these there are 2 or more of the synths playing at once.
