The old rules still apply. That is, these "rudiment" lists, even when multiple tracks are used, should come last.

MULTITRACKS partA=track1patternA track2patternA track3patternA
MULTITRACKS partB=track1patternB track2patternB track3patternB
MULTITRACKS partC=track1patternC track2patternC track3patternC
' and then your final line could look something like this:
partA partB partA partC

And, as in non-Multitracks mode, a list of MULTITRACKS variables (not the MULTITRACKS definitions) should be the final line(s).

RAW b=25+B+C        'Play 8th note, Volume 5 on voices A + B + C

RAW d=25>D          'Play 8th note, Volume 5 on voice D ONLY

Why did I do this?
I wanted to allow the drumputer to do "real" music that used more than 6 pitches and the more note types defined the cleaner your scripts can be.

Why only for the Standalone version (not for the web)?
Every time you push the "Let's Hear It" button in the online version to generate your file, programs are run on my Internet Service Provider's (ISP - "Canaca.ca", Toronto, Ontario, Canada) computer. I have to ensure that the program that runs on their servers is fairly efficient or they're liable to get P.O'd (after all, I'm only one of roughly 5,000 users so I can't have my Drumputer hogging all their computing resources. This allows me to ensure them that I'm taking steps to write a more efficient program from their standpoint and therefore they'll leave the Drumputer alone.

And, because of these increased capabilities it will require more memory to run (you probably won't notice it) but, again, my ISP would.
