Studio Electronics ModStar SEM Filter EuroRack Module
The Studio Electronics Modstar SEM is a state variable EuroRack filter module based on a combination of the original SEM and the newer OBX filters along with some modern tweaks.
- All analogue Eurorack filter module
- State variable filter with simultaneous high pass, low pass, and band pass outputs
- 12 dB/oct slope on all filter types
- 7 patch points

The Modstar 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 12 dB/oct 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 SE. It has a modest current draw, which it pulls evenly from the plus and minus rails.
This 12 dB filter is capable of lighter, more subtle tones than the other three models in the Modstar range. This isn't to suggest the filter's Low Pass mode can't cater for fat and punchy, because it can. And with style and panache!
Three attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, LP HP, INPUT and OUTPUT, delivering smooth, detailed, and complex 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 direct the deepest manipulation.
All Controls and Patch Points
FREQUENCY – Adjusts the frequency, or cut-off of the filter.
RESONANCE – Adjusts the resonance of the filter.
FULL HALF TRACK – Switch between full and half keyboard/voltage tracking.
FREQ CV 1 – Frequency control voltage 1 input attenuverter.
RESO CV – Resonance control voltage input attenuverter.
LP HP – Low Pass / High Pass attenuverter.
INPUT – Adjusts the audio input.
OUTPUT – Adjusts the audio output.
1 V/O – One volt per octave control voltage input.
FREQ CV 1 – Frequency control voltage 1 input.
BP OUT – Band Pass Output. No cable patched, BP passes through the mains.
RESO CV – Resonance control voltage input.
INPUT – Audio input.
BP LP-HP – Switch between Band Pass and Low Pass - High Pass modes.
OUTPUT – Audio output.
