hello, you can pass strings as p-fields like this:

Sfile = p4

Also, have a look at the strset/strget opcodes. You will need to put
the numbers you assign to strings into f-tables and index them using
the table opcode.

hi michele -
i think both ways are possible.
i am not sure what you mean by muting/unmuting. doing this live, during
the performance?
what is the difficulty in your second choice? playing different tracks
simultaneously can be done simply by adding audio signals, or by routing
via the outch opcode.
perhaps you should give a concrete example?
best -
