I'm building 4 electronic timpanis. Each drum will need to have a memory to hold the sound samples, an LCD screen to read the pitch, a pedal to change the pitch, and a pedal to shorten the sample, similar to a staccato pedal on a piano. The pedals can connect to the drum preferably with a 1/4" jack, or midi cable. There will need to be a 1/4" out to hook up to a amplifier. The piezos will be force sensitive to detect the volume I want to produce. I'm looking for someone to build the electronic internals for each drum. I will be building the physical drums.
