Use MIDI Modulator to control plugin parameter
I was wondering if there's anyway to use the LFO section of the MIDI Modulator to control parameters of plugin(s) on other channel strip(s)?
Specifically, I've got a Waves One Knob Filter on an aux channel, and I want to modulate the cutoff frequency with an LFO. I have the MIDI modulator set up on an external instrument channel. I also have the cutoff frequency mapped to an on screen control. However, I can't seem to get the MIDI LFO to target either the plugin control directly, or to target the on screen control.
Is this possible within Mainstage 3? Or should I start looking at something like Bidule to make this work?
