FM, PM and RM between sources in the waveform editor

So how about making it possible to set sources in the waveform editor to modulate frequency, phase or amplitude (FM, PM, and RM) of another source? Could be a modifier where one can pick the source and set the amount. Like, we already can turn the waveform into a phase modulator for sine carrier.


This would greatly benefit from having individual setting for normalizing and removing DC for every source.

Edit: the normalizing and removing DC seem to affect the combined waveform so the above hidden text isn’t an issue after all.
