chaos music composer and basic

[eflake]

I'm working on resurrecting an old PD game my friend made, want to use CMC or something similar to make music. I want to make a simple title screen with music playing. Is there any basic code I can use for this, or some other format which would be easy to compose and use? Thanks.

If you have CMC and REP files loaded in memory you just call desired music using

X=USR(REP,SONGMUMBER,CMC)

 

and stop with:

X=USR(REP)

 

where:

REP - player address

SONGNUMBER - self explanatory (counting from 1)

CMC - music address

 

CMC and REP addresses are strored as haxadecimal ones in program. For Atari BASIC you need to convert then to decimals.

 

And that's all. You just have to obey the order music on -> music off. Don't turn it on or off twice beacuse it may hang the system.

If I save a CMC file, it will store the REP file too?

No. To save REP file, press Control+M, there address will change just next after music end (but you can alter it of course), and then you press Return/Enter the file will be saved. Beware not to cross CMC/REP address and also not to damage any important data in memory.
