Tripper free VST has 18 filter types, modulatable by env follower or tripped env. It’s good for wahs, using audio as filter mod source and distorsion. The filter curve is animated, so you can see also what you are doing a touch easier.
Also you can turn the modulation off and have static cut. MIDI learn is supported. The depth knobs are logarithmic, so the low cutoff for wah is easier to hit now. Go hacks on res and cut via controller! Right click on knob enables learn, select MIDI source with the little female plug. This version has 2 new filter types, formant(vowel) and comb.
