I have built a device that i call the MIDI Wing Chun Dummy whose trigger design involves having the piezo's in such close proximity to one another that I am having major problems with the isolation of triggering.
Is there a button or similar type of device out there that behaves the same way as a piezo so that it functions properly with megadrum?
