For typical "surf" sounds you should also try the EMS style (or MOTM
LFO) variable ramp waveform as a modulation source. Produces the typical
envelope of swelling and then breaking waves when set to approx. 70%
to 80%. Voltage rises slowly to maximum, then falls down abruptly
to an intermediate level, then continues to decay slowly to minimum level,
then rising again.
