Filter Sweeps?

It already is -- just turn the realtime controller knob labelled "Cutoff" (that's usually the active function by default, but note that each knob has three different potential programmed functions so you may have to push the button next to the knobs to toggle the selected parameter being controlled).

Anyway, "Cutoff" will set the cutoff frequency of the filter(s) in the selected patch. That is a filter sweep. If you want to get fancy (and you have two hands free) turn resonance too. That will add more and more pitch boost around the cutoff frequency. Sometimes "filter sweeps" include a resonance boost as well.

Nice to have you back Phil!

This has got to be the nicest community on the net. Thanks, Artemio!

In Patch Edit scroll down to the Controller settings, there you can assign any of the controllers (and other parameters of the synth engine) to control the filter. Choose a control source such as a knob or the mod wheel, and the filter as the control destination
