Particle Fountain is a free software synthesizer developed by ndc Plugs. Available format(s): VST for Windows, macOS.
Particle Fountain is a monophonic synth that attaches a sound (either a sawtooth or a square wave) to a bunch of particles, which move in a 2d space like a fountain. The particles’ position in the space then determines certain aspects of the sound (frequency, amplitude, panning). There can be up to 200 particles in use at any one time.
