Projects / Cumulus


Cumulus is a software synthesizer which implements the Asynchronous Grain Synthesis. This synthesis allows you to create very original sounds to be used in your music (mainly percussive and ambient background sounds). It features a convenient QT-based GUI where each paramter can be controlled by an envelope, the ability for all parameters to be controlled with hardware controllers (MIDI-controllerbox), an interface to use a MIDI-keyboard (polyphony adjustable, default 8 voices), internal 32-bit accuracy, an internal sampling rate that can be any multiple of the external one, and full realtime capability with parameter changes audible within around 50ms, depending on system latency.
