Simpler than ever but need a little sacrifice about the Stereo effect... but the whole thing can be done within an hour.
Record your audio track on the Left channel, place some special tones frequency on the right channel... your pic is attach to the Right channel of your CD player/PC soundcard and he just decode the tones. For a x tone it activate 1 or multiple igniter.
KISS engineering!
-------------------------------------------------------------------------------------------------
Depending how many OUTs you need... PIC16F628 is more than enough (16F627 would also do). Use the internal comparator to convert the dinky audio signal to TTL compatible, feed the comparator output to the T0CKI input, use the internal timer/counter to count the frequency (or use count) and use an array, Lookup or whatever else method to convert frequency to outs.
Some other see something much simple?

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
