I'm building a synth-like patch, with the built-in Helix expression pedal controlling the high-cut (low-pass) frequency of the Low and High Cut block.
With the pedal min at 1kHz and max at 11kHz, there's not enough fine control at the low end. If I drop the max range of the pedal, I won't have enough highs with the pedal fully down. If there's an option for a logarithmic sweep like in the Volume block, that will solve the problem. Unfortunately, I can't figure out how to do that. Care to help?
And yes, I've tried using the Wah blocks, but all of them have a very pronounced resonance peak at the cut-off frequency of which there's no control to cut out.
Side problem: Is there a low-pass filter block that goes lower than 1kHz?
