Great, please finish the work with Le IIgs épluché :-)

There are really a couple of important things to note if you want to play sound effects while a music is being played:
- the index of the free oscillators (some are reserved by the music routine)
- the @ of the sound wave in the DOC RAM
- its/their length(s)

Do not take it for granted, but, from what I've read over the years:
- oscillators 30/31 are for the tempo
- oscillators 28/29 are free
- oscillators 0/27 are used/reserved by the music routines

Read the MidiSynth documentation, it is worth it.
