VMMF

Quirky eurorack state variable filter

A 2 pole state variable filter with a couple of differences. The 'Voltage controlled Multi-Mode Filter' (VMMF) is a 2 pole OTA based filter. It has a few controls that are not normally found on filters, and probably for a good reason. Emits a range of gritty and squishy sounds.

There's no 'resonance' knob, resonance and character of the filter are instead adjusted by the interplay of a few other parameters. This is true of most of the controls on the VMMF, the impact of most controls will depend on the interplay of settings. This leads to the filter excelling in use for evolving sounds, but also great if you want to settle in a specific area and explore.

Real talk, it can be less intuitive than a lot of filters, but it’s rewarding to explore, especially if you enjoy harsher sounds.

On its own, it can be a nice sine wave oscillator, tweaking the controls can allow for reasonable 1v/o tracking. It can also ping beautifully, and responds very nicely to frequency modulation whilst doing either of these things. Works nicely for pingy bloopy krell patches.
