Hey Lunetta fans: see this new thread:

http://electro-music.com/forum/post-370586.html#370586

for a way cool circuit that makes percussion sounds using one opamp, four resistors, and two capacitors. Very exciting thingie!

I have played around with the values of the Rx resistors and changing them alters the tone of the percussion. Also putting another 0.1uF capacitor from the input to ground affects the tone as well. While experimenting with different values I heard classic drum synthesis sound types, so this is really working!
