Greetings: Our church band consists of drums, bass, acoustic guitar, electric guitars, keys, and vocalists. Our only drummer has moved on, and It may be awhile until another drummer is found. This leaves the church band in a predicament. What we need is a snare beat, which I can manipulate real-time (the order of songs constantly changes, so pre-programming tempos wouldn't work). What would be a few inexpensive ways to produce a snare sound in real-time using my foot? Thanks!
