c_freq = carrier frequency (mf = six-octave range, 2-130 and 60-4000 hz)

lfo_type = LFO signal function, ie. mf_sin or mf_square

lfo_freq = LFO frequency (mf = 0.1 - 25.0 hz)

lfo_amp = the amount that the LFO output sweeps the carrier sin oscillator

drive = pre-multiplier for mod_sig

x_mix = crossfade from unmodulated to modulated audio (-1 to 1)
