About

Cumulus is a software-synthesizer with following features:

• Implements the Asynchronous Grain Synthesis which is very multifaceted.
• Fully realtime capable.
• MIDI-Port to Controllerboxes (all parameters can be controlled via MIDI!), Keyboards (Polyphony, 8 voices) and Sequencers.
• Convenient GUI with drawable envelopes for each parameter.
• Internal 32 bit sampling resolution and a multiple of the external samplingrate.

Cumulus was originally developed as a parallel application on a cluster of LINUX-workstations. I used a cluster of 7 Pentium-233 nodes, connected by the very fast "Easynet" network which was developed by the Institute of Electronics at the ETH Zuerich (Switzerland). I hacked the code to run on a single PC and I achieve about the same performance on a single modern PC (Thunderbird-800). The code runs on any GLIBC LINUX distribution with QT Devel >= 2.0 (GUI) and AFsp (a library to load and store .wav-files) installed. Note that the code is published under the GNU GPL.
