; This instrument shows how the moscil opcode<\n>
; can be used for a sort of
; "indeterminancy" aspect in composition. knum<\n>
; and kvel control the output
; of MIDI notes and their velocities over p3<\n>
; (note-stream duration as specified
; in the score). kran output is used for kdur<\n>
; (actual duration) and kpause
; (pause between notes).

; The moscil (MIDI oscillator) opcode permits<\n>
; control of MIDI channel, note-number,
; velocity, duration, and time between notes.
