Black Corporation - ISE-NIN Voice

Black Corporation's イセーニン (ISE-NIN) Voice Module — The Soul of Juper-8.

A complete Jupiter-8 voice stripped down to the Eurorack format. Black Corporation manages to pack the essence of their ISE-NIN synthesizer into a single voice module that delivers that sought-after Japanese discrete analog character.

The dual oscillator architecture remains fully intact, offering deep modulation possibilities through PWM, sync, and cross-modulation. VCO-1 gives you triangle, ramp, pulse and square, while VCO-2 trades the triangle and square for sine and noise - providing a wide palette of raw waveforms to work with.

The defining element here is that unmistakable 80s filter section with both high-pass and low-pass (-12dB/-24dB) capabilities. Two snappy ADSR envelopes handle the dynamic shaping, with ENV-1 featuring a polarity switch for more experimental modulation routes.

The basic 1V/oct, gate and audio connections make it immediately playable, but in case you're looking for more ways of CV control there's also an optional breakout module for proper modular integration [イセーニン (ISE-NIN) BREAKOUT Voice Expander Module]. Combined they form a modular jupiter voice on steroids.
