Soundgrain is a graphical interface where users can draw and edit trajectories to control granular sound synthesis. Soundgrain is written with Python/WxPython and uses Pyo as its audio engine.

thinksynth builds sounds out of a graph of DSP nodes — oscillators, filters, envelopes, delays and arithmetic — described in a small language and rendered in real time. Patches assign those graphs to MIDI channels, so one instrument can layer several voices.
Every node is a plugin, and the set that ships covers subtractive and FM synthesis, resonators, waveshaping and a range of filters. New ones are ordinary shared libraries dropped into the plugin directory.
