[LAU] Voice-to-drums in general and the Trigger LADSPA in particular

Hi all, I am in search of a more or less easy way to do voice-to-drums - that is, to trigger drum samples (MIDI or otherwise) and control their volume (velocity) using my voice recorded from a microphone. Real-time is not necessary, and neither is multi-sample capability. The objective is to create more lively, groovy drum loops, which I can emulate with my voice. I tried using the Trigger LADSPA plugin but so far have not had any success with it. The output I get makes no sense to me, and the meaning of some parameters like e.g. threshold is unclear due to units chosen. Can anyone point me to any HOWTOs on using Trigger or describe the workflow in a few words? I would also like to know about possible alternatives to Trigger, including those for Windows. Thanks in advance, Artem Vakhitov
