Synthesis Technology’s Paul Schreiber let us know that his new Euro-format E430 Morphing SVF is now available.
The E430 is Schreiber’s take on the classic Oberheim SEM 12dB/oct state-variable filter, with 3 added features:
- Individual filter outputs: Low-Pass, Bandpass, Notch, and High-pass
- Voltage-controlled Morph output: sweeps between LP-BP-HP or LP-Notch-HP via panel switch
- Voltage-controlled Resonance
Schreiber notes that the original SEM circuitry was not “improved” or updated, adding that “Great care was spent through measurements and beta testing to duplicate the SEM’s unique sound.”
The design incorporates 40 year old circuits such as:
- LM301 audio input op amp
- LM741 resonance op amp
- RC4558 audio summing op amps
- Discrete JFET current buffers between filter sections
- CA3080-class OTAs
- No self-resonance unless patched externally
Other features includes 2 FM inputs (FM1 is a reversing attenuator) and user-programmable LED color for the Morph switch.
