Description::
|
||
|
|
|
||
|
|
A sawtooth wave that is hard synched to a fundamental pitch. This
|
||
|
|
produces an effect similar to moving formants or pulse width modulation.
|
||
|
|
The sawtooth oscillator has its phase reset when the sync oscillator
|
||
|
|
completes a cycle. This is not a band limited waveform, so it may alias.

argument::syncFreq
|
||
|
|
|

|
Frequency of the fundamental.

argument::sawFreq
|
||
|
|
|
||
|
|
Frequency of the slave synched sawtooth wave. Should always be
|

|
|
greater than

argument::mul
|

|
|
|

|
|
Output will be multiplied by this value.
