Image-Line has released the VSTi version of DrumSynth Live for Windows.
DrumSynth Live is the VSTi plugin (and FL Studio) version of the popular DrumSynth standalone originally created by Maxim Digital Audio. It features simultaneous support for 120 real-time programmable drum patches, each assigned to a separate key (C0 to B9). You can morph dynamically from one drum patch to another. The sound is created by two noise generators, filtered by bandpass filters with an incredible range - you can set anything from single frequency (sine wave) to full white noise.
DrumSynth Live, priced at $35, is available for Windows. A demo version is available.
