Maybe he was using Massive with the Modulator to rock a parameter back and forth... and then used the Modifier midi plug to limit the range (floor) because the Modulator only let him control the top of the range. I would like to use this same idea with the big knob of the Ringshifter if possible.
Yes! I remember him doing that, for sure. So in Massive, assign a MIDI CC# to a parameter. Then he was using the Modulator to generate that CC# with an LFO, then the Modifier to scale and offset the range of the LFO.
However AFAIK you can't control the big knob of the Ring Modulator with MIDI CC.
Why not just use Smart Controls instead?
