shapesynth

Shape is a polyphonic synthesiser allowing the user to draw the shape of the oscillator waveform. The positive side of the oscillator is represented by 32 blocks and the negative side is its mirror, generating all sorts of possible raw retroish sounds. Add effects like arpeggio, stereo delay and a resonant filter and record your sounds on a classic tape. Connect to other apps with audiobus, inter app audio and midi.
