Perform the control change specified by number and value (0.0 - 128.0). | |
StkFloat | tick (unsigned int channel=0) |
Compute and return one output sample. | |
StkFrames & | tick (StkFrames &frames, unsigned int channel=0) |
Fill a channel of the StkFrames object with computed outputs. |
STK moog-like swept filter sampling synthesis class.
This instrument uses one attack wave, one looped wave, and an ADSR envelope (inherited from the Sampler class) and adds two sweepable formant (FormSwep) filters.

stk::Moog::Moog | ( | void | ) |
Class constructor.
An StkError will be thrown if the rawwave path is incorrectly set.
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::Sampler.
