I use a 74C922 keyboard encoder chip (along with 4066s) to do what you're asking. Expensive chip, but it's got the de-bouncing and everything built in. I even got it to turn LEDs on without any extra chips. You can use the BCD outputs to directly switch various things on/off - just use the switch inputs that output the binary numbers (effect combinations) you want to use, leave the others unconnected.
