Roland System 700-based state variable filter

State 700 Mk2 is an update of this popular module. The Mk2 is the same size as the Mk1, at 10HP wide, but features additional audio and CV inputs, both with their own attenuators. Based on the Roland System 700 state variable filter module, State 700 provides lowpass, bandpass and highpass outputs simultaneously. The Mk2 features upgraded outputs from the original module, keeping signals more in line with Eurorack output levels. A big part of the sound of the State 700 is the way in which resonance is reduced as the audio inputs are driven harder. It won't self oscillate with a hot audio input, throttle back a little and you'll get squelchy ear bleeding resonances!
