Studio Electronics Modstar SEM, DEMO UNIT
This item is used, has been fully tested and is guaranteed to be working. State Variable Filter Module
The 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, evenly from the plus and minus rails.
If you've heard the SEM filter in the Boomstar desktop you also know that this 12 dB favorite is "capable of lighter, more subtle tones than the other three models. This isn't to suggest the filter's Low Pass mode can't cater for fat and punchy, because it can. Looking for deeply gratifying tonal variance and this emotional warmth? It can reach into your head and heart, and stay as long as desired. Thank you Lord Tom Oberheim for this marvelous design/template from which we were able to work our very own Studio Electronics eurorack filter enchantments.
