Hi,
I start playing with the NOTES commands, making an endless 'music' generator. The basis for that is the code herunder.
It occurred to me, that the two tracks, defined in the notes_gen() function are played sequentially and not simultaneously as expected (because they are different channels).
Can the be forced to play simultaneously? A second question: how can channels be indicated (suppose one want to play a percussion track on channel 10)?

Code: Select all

new_song: notes set n$ ! notes play
n$=notes_gen$()
wait: if notes_time()<notes_length() then wait else new_song
end

def notes_gen$()
a$="0:ccc   ddd"",""19:we2 f"
return a$
end def

Tracks are indicated in NOTES SET command - they are separated by commas.
Example with percussions (notes on the 10th track) is the last example in NOTES SET command documentation.

Thanks for the quick response (as usual). I understand now.
One last remark:
The command NOTES SET <string constant>,<string constant> results in Playing the two tracks simultaneously.
However the command NOTES SET N$, where N$=<string constant>,<string constant> results in playing the two tracks sequentially on the same channel (as is the case in the little test program). Is that a bug?

No, why this is a bug? Notes in one track are played sequentally, this is normal behaviour.
That comma in the notes string is a bug

but sB handles it without panic.

Why is that comma a bug? The double quotes each mean an embedded single quote within a string, hence it is one string, and a comma is a valid caracter in a string, not?

Because comma has no meaning in a notes string.
