Resonance is under voltage control with attenuverter as well allowing for great timbre modulations. It is particularly useful to recreate accent patterns à la 303 which boost the resonance a bit.
There is a gain at Altar's input to beef up your signal which then distort the filter core.
The filter tracks 1V/oct for 4-5 octaves and can turn into a very sweet sine oscillator. Try using it with
- Gain control to distort the filter core
- Color to go from band pass to low pass to high pass filter
- Frequency with 1V/Oct
- Attenuverters on Color, Resonance and Frequency CV
