In Timer, Op Amp & Optoelectronic Circuits & Projects by Forrest M. Mims III there is a percussion synthesizer on page 71. The author says "bell and drum sounds can be produced", but I was unable to make any noise that could be described as a bell or a drum. I followed his tuning directions, but mostly sounds like an out of tune radio. Has anyone built it before? Is it possible that stray capacitance from the breadboard could causing problems? Any other ideas?
