pethu has announced the release of the Hahaha DS-01 Drum Synthesizer.

Hahaha DS-01 is a very 'retro' drum machine with all the sounds generated by oscillators, noise generators, and ring modulators. It has 8 drum channels with generous tweaking and mixing capabilities (volume, pan, parametric EQ).

Hahaha DS-01 is available for Windows as a VST instrument plug-in and it is free.
