How to deal with multispeed tunes?

hello you coders!

i'm currently doing my first (except for some bullshit from back in the late 80s/early 90s) steps in coding and while checking out some tunes from HVSC as background music i stumbled across some 'multispeed' tunes. some questions came up my mind...

1. am i right saying that multispeed means calling the playroutine multiple times per frame?

2. is it just calling the routine at any time, just calling it often enough in every frame?

3. or does replaying multispeed tunes require a special timing?

4. would loose $d012 polling be sufficient? (no stable interrupt)

i have to admit that i haven't tried out yet and wanted to get the theoretical background before i started off into the (possibly) wrong direction.

thanx in advance!

@HCL >> sure, it's still not 100% what was prooved by my 'galaxy bounce remix' - it sounds apparently different on real chip.
