receives the polyphonic pitch modulation signal of the parent sound generator

Parameters

This node will receive the modulation signal of the pitch modulation chain of the parent sound generator:

• if the network is loaded in a ScriptnodeSynthesiser, then it will pickup the modulation signal from the pitch modulation chain of itself
• if the network is loaded in a FX module (either Script FX or Polyphonic Script FX), then it will pickup the pitch modulation signal from the sound generator that the FX is residing in.
• if the network is loaded in a modulator module (either Script Envelope or Script TimeVariant Modulator), then it won't work and likely crash.

Note that while the plotter signal in the UI of this node suggests a normalised range from 0 to 1, the value that is sent out of the modulation output is actually a raw pitch ratio value that can be directly fed into the FreqRatio parameter of any oscillator without conversion. If you modulate a LFO with the full bipolar intensity to get a +- 12 semitone modulation range, the values from this node will oscillate between 0.5 (=-1 octave) and 2.0 as you can see here:

)

The rationale is that if you start modulating this on a per sample basis for FM stuff or other things that require a good pitch resolution, the overhead of converting the range to a pitch ratio comes with a non-signifant overhead (also the pitch ratio was already calculated, so we would have to calculate that again).

By using the pitch ratio domain and the unscaled modulation mode , this node achieves the best performance possible for that setup.

As with all other modulation nodes: starting with HISE 5.0 you can use them in all configurations, even in compiled networks.
