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

Of course (but that is probably obvious) being human voice monophonic you will have to do "a piece at a time" I'll give it a try (although I never used the LADSPA plugin version): A trigger is usually quite simple. It "monitors" an input signal, when the signal's amplitude goes above the threshold (which you set) it will play (trigger) the chosen sample. The hold parameter (usually measured in milliseconds) is important because it sets how long the Trigger remains inactive (holds) after it triggered this avoids re-triggering the sample too quickly especially if the input signal remains above the threshold for too long. Here is an very simple example of what you're probably thinking of: http://lorenzosu.altervista.org/temp/dump/trigger_test.ogg Hard panned left is the audio input (in this case it's not my voice but me tapping on my crap laptop mic) hard right the triggered sample. You can noticed some taps are "missed" this is because they were below threshold (too quiet). The hold was at 80 ms (excuse the horrible quality of the audio input quickly made on my laptop and it's night here..) Well I made a very simple trigger for PD [1] a while ago (to be used mainly with ardour - used for the above example). Lorenzo [1] http://lorenzosu.altervista.org/pd/trigger/
