DrumSynth Live features simultaneous support for 24 programmable real-time drum patches, each assigned to a separate key (C4 to B5).
You can morph dynamically from one drum patch to another - just select the patch to morph to and tweak the morph amount wheel.
In DrumSynth Live, sound is created by two noise generators and filtered by bandpass filters with incredible range - you can set anything from a single frequency (sine wave) to full white noise.
FL Studio comes with the demo of DrumSynth Live pre-installed. The demo version has all the functionality of the 'real' generator, although all channels using it are deleted when saving.
