BMFLTR is a Band-Mix State Variable Filter (SVF).
Unlike typical SVFs, Lowpass/Bandpass/Highpass channels can be selected depending on the input position. This is the same characteristic as the Steiner-Parker filter, but the BMFLTR has a smoother tone and is less noisy.
The input signal for each band can be attenuated using its respective slider. Also, if you patch a cable only to the LP channel, the same signal as the LP channel will be input to the BP/HP channel. This allows you to adjust the strength of each band with a slider, just like a graphic equalizer. Also, if you input different signals to each channel, you can use it like a band-divided mixer (for example, input kick drum to LP, snare to BP, and hi-hat to HP).
The FM knob acts as an attenuverter. The signal input from the FM jack is adjusted by the FM knob and then modulates the cutoff frequency.
At maximum Q, it will self-oscillate. It can be used as a sine wave oscillator by patching it to the V/OCT input.
In addition, the built-in limiter circuit limits the output volume to a range of approximately +-9V, so the volume will not increase dramatically even if the oscillation becomes unstable.
(BMFLTR is a unique improvement based on the circuit designed by Osamu Hoshuyama. Thanks! : https://understandcircuit.seesaa.net/article/201202article_1.html)
