Studio Electronics Boomstar Modular System Modstar SEM Filter Module
Studio Electronics SEM is known as a 'voltage-controlled state variable filter' because it provides simultaneous high pass, low pass and band pass outputs, all with a 12dB/octave slope. The notch is the inverse of the bandpass, achieved by summing the low pass and high pass outputs. This version is a combination of the original SEM filter and the newer design from the OBX, along with improvements by Studio Electronics. It has a modest current draw, evenly from the plus and minus rails.
Three attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, LP HP, INPUT and OUTPUT, delivering smooth, detailed and ever-variable expression.
Switch it up
FULL and HALF strength filter frequency keyboard/voltage tracking, and BP / LP-HP modes.
Patch it up
Seven patch points — 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT, BP LP-HP and OUTPUT — jack you in.
- Module controls
- FREQUENCY knob: adjusts the frequency (or 'cutoff') of the filter.
- RESONANCE knob: adjusts the resonance of the filter.
- FULL / HALF TRACK switch: switches between full and half keyboard/voltage tracking.
- FREQ CV 1 knob: frequency control voltage 1 input attenuverter.
- RESO CV knob: resonance control voltage input attenuverter.
- FREQ CV 2 knob: frequency control voltage 2 input attenuverter.
- INPUT knob: adjusts the audio input level.
- OUTPUT knob: adjusts the audio output level.
- Patch points
- 1 V/O input: one volt per octave control voltage input.
- FREQ CV 1 input: frequency control voltage 1 input.
- FREQ CV 2 input: frequency control voltage 2 input. Get tricky with the second attempt!
- RESO CV input: resonance control voltage input. Use for shimmers or howling wolf tones.
- LP HP: low pass / high pass attenuverter.
- INPUT: audio input.
- OUTPUT: audio output.
