Triggered wave generator

[Prospective Volition]

Hello, I am an electronics student and I hope you don't mind me asking a few 
questions about a progect I am doing at the moment.

I am building a wave generator which is to be triggered by a piezo 
transducer. I see it should be easy enough but I need to know a few things. 
Do I need to amplify the signal from the transducer to trigger the WG? I 
want the sound to be close to that of a snare drum, (so I can use it to 
practice), any suggestions on oscillator circuits to use? I was thinking a 
wein-bridge with gated white noise?.


Thanks for any replies ....
