XORbot (synth)

XORbot is another fairly simple noisebox synth, and similar to NANDroid in that it uses logical operations to generate sounds, and features a similar modulation setup and synth engine. However, the sound generation method itself is different enough that the range of sounds XORbot can make is quite different– though still quite crude and noisy.

Like NANDroid, there is no MIDI key tracking by default, though it is available as a mod source and there is a gate and volume envelope that can be enabled and triggered by MIDI notes.
