Roland JX-8P Analog Polyphonic Synthesizer

The JX-8P is a polyphonic, hybrid analog-digital synthesizer with 61 keys and five octaves, velocity response and aftertouch. New modulation parameters also enable synthetic sounds. Its predecessors were the JX-3P and the MKS-30 rack. The Alpha Juno 1 and the MKS-50 and MKS-70 racks appeared at the same time, followed a little later by the larger JX-10.

The JX-8P features DCOs per voice for digital control but analog sound generation, plus two software-generated ADSR envelopes and an LFO that generate square, pulse, noise (white noise) and sawtooth, high and low pass filters, two types of chorus effects and three different sync modes. It offers different play modes, twice polyphonic, unison and solo, one of which can stack all oscillators into a single monophonic sound. It also has MIDI. Programming is done either via Edit or the external Roland PG-800 Programmer. The sound presets are organized in two banks with 32 sounds each. In addition, 32 of your own sounds can be stored in the internal memory and a further 32 sounds on an optional M-16C cartridge. Patches can also be imported and exported via system exclusive (Sysex) MIDI commands. (Source: Wikipedia, amazona)
