So.... after researching plans on the internet, I have decided to build my own electronic drum kit using piezo elements wired out to 1/4" jacks and sandwiched between practice pads. The construction of the actual kit seems pretty straight forward. My question has to do with the drum module I would need to plug the pads into. I am looking for a low cost option to trigger the sounds as I am not even sure how effectively this thing will work. The obvious solution would be to get a cheap drum module off ebay or go for something like an Alesis I/O as I am planning to trigger via midi (Steven Slate) samples from my computer. However, i was thinking maybe I would be able to use my digi 002 to test the pads somehow. Anybody got any ideas of how to do this? I was thinking I could use some sort of audio to midi software like Midifier to trigger Kontakt.....or simply use drumagog. However, since the piezos aren't exactly like mics, i dont know if they would trigger such software. Like I said, it would be cool if I could test the homemade pads before investing $150 in something that might not work that great to begin with. Anybody got any ideas, thoughts, or experiences?
