I've been messing about with the SFX Sound Expander for the C64 recently.
Have read pretty much all I can find.
Using the documents widely available from Lee and Totto (I think!), I cobbled together a rough BASIC program which produces a noise. All's fine.
I'm trying to use Percussion mode now and am getting noises which sound like someone spitting!
Can anyone give me some pointers as to how to trigger the drum sounds available on this chip?
Ideally, what is the sequence that sets the chip into percussion mode and triggers say a snare drum?
