STK periodic/random modulator.
This class combines random and periodic modulations to give a nice, natural human modulation function.

stk::Modulate::Modulate | ( | void | ) |
Class constructor.
An StkError can be thrown if the rawwave path is incorrect.
Fill a channel of the StkFrames object with computed outputs.
The channel
argument must be less than the number of channels in the StkFrames argument (the first channel is specified by 0). However, range checking is only performed if STK_DEBUG is defined during compilation, in which case an out-of-range value will trigger an StkError exception.
Implements stk::Generator.
