;; (pm-osc rate carfreq modfreq index modphase)

;; Phase modulation oscillator pair.

;; carfreq - carrier frequency in cycles per second.
;; modfreq - modulator frequency in cycles per second.
;; index - modulation index in radians.
;; modphase - a modulation input for the modulator's phase in radians
