Re: Using Drum Triggers
2005-06-07 by paulhaneberg
I too have a V-Drum set. I hadn't thought about using it to trigger the modular directly, but it seems like an idea with possibilities. The biggest problem is with false triggering. I think the simplest way to address this problem is for you to have a circuit that compares every impulse on all the pads and initiates a trigger for the pad with the largest impulse. The difficulty here is that you could hit more than one pad at a time, or more than two if you use your feet. You also need to have a delay time between triggers for each pad to prevent multiple triggers from just one hit. A sensitivity control could either control the amplified gain of the signal prior to triggering, or could actually set the level required to generate a trigger with a comparator. I don't think noise is too much of a problem, but hitting anywhere on the kit, including the stand can potentially generate an unwanted impulse. Even an overenthusiastic fellow band member can generate a false trigger by jumping around. It's a difficult problem, that I've never seen solved entirely to my satisfaction. I use my kit for recording only, and I always edit the midi stream, so I'm very aware of all the false triggering that does occur. Paul Haneberg
