[sdiy] CEM3394

i have the data sheet. i guess what i'm in need of is some kind of 
information on simple application of these chips. are there any projects or 
hints in books or on the web? i want to start getting some use out of the 
resonance, applying the pitch decay controls on the panel to other parts on 
the chip, etc. am i in danger of damaging the supply rails by simply hooking 
parts of the circuit to parts of the chip without absolute knowledge of what 
might happen?

thanks for your patience everyone
greg
