sr = (optional) - set sampling rate to n1 samples per second per channel. The default value is 10000.
kr = (optional) - set control rate to n2 samples per second. The default value is 1000.
ksmps = (optional) - set the number of samples in a Control Period to n3. This value must equal sr/kr. The default value is 10.
nchnls = (optional) - set number of channels of audio output to n4. (1 = mono, 2 = stereo, 4 = quadraphonic.) The default value is 1 (mono).
In addition, any global variable can be initialized by an init-time assignment anywhere before the first instr statement.
All of the above assignments are run as instrument 0 (i - pass only) at the start of real performance.
