Erik Sigth has released version 2.6 of ShapeSynth. The update adds new sphero/accelerometer controls and arpeggio delay filter (adf).
Shape is a polyphonic synthesiser allowing the user to draw the shape of the oscillator waveform. The positive side of the oscillation is represented by 32 blocks and the negative side is its mirror, generating all sorts of possible raw retro sounds.
