  • E430 Morphing SVF current 18 HP state-variable-filter vcf

    Faithful re-creation of the classic Oberheim SEM 12dB/oct state-variable filter with individual LP, BP, Notch, and HP outputs, a voltage-controlled Morph output, and voltage-controlled resonance. Built from period components including LM301, LM741, RC4558, CA3080-class OTAs, and discrete JFET current buffers.

  • E440 Discrete OTA VCF discontinued 14 HP

    Discrete OTA voltage-controlled lowpass filter with three simultaneous slope outputs (2-pole/12dB, 3-pole/18dB, 4-pole/24dB), voltage-controlled resonance, and input Drive control. Inspired by SSM2040 topology.

  • E520 Hyperion Effects discontinued

    Stereo audio effects processor operating at 24-bit 48kSPS with algorithms including delays, frequency shifts, phasing, flanging, filters, reverberation, looping, sampling and frequency domain manipulation. Features CV control of real-time parameters and a graphic user interface for Eurorack and outboard use.

  • E490 Ladder VCF ↗ current ladder-filter vcf
