OttoPhilter is an auto/touch wah filter with LFO control and sub-octave generation and a second auto/touch wah filter on the sub-octave. It has all 64 bit interal audio processing.
There's a level meter tied to the touch wah sensitivity to help you adjust OttoPhilter to suit your playing dynamics. OttoPhilter has two driven resonant filter sections - one on your input signal and one for the generated sub-octave. The filters sweep by using triggered envelopes or tracking the input signal or using LFOs. It's the ultimate envelope filter.
