You can do this with the 'instr' statement in SAOL:

instr main() {
  ivar i;
  table ftSine(harm,4096,1);

  while (i < 9) {
    instr toot4(i,1,75,...);
    i = i + 1;
  }
}

Then you just have to call the 'main' instrument from the score.
You can combine these two methods (score-based and dynamic note
generation) freely in SAOL.

This isn't a SAOL list; this discussion should probably
move onto saol-users.

Best to all,
