MEX-8000 memory expansion adds 4 extra banks. Memory backup system is older with no CR-2032 battery and no Sysex handling.ĮX-800 module enhanced version of poly800 mk1 with Midi thru, Midi sysex. Poly-800 first version, It is quite the same it but features a Chorus board instead of digital delay. VST PLUGIN / SAMPLED VERSION there are some free and commercial samples set: LEFT - RAM system based on a CR-2032 battery, replacement needs soldering skillsĮDITOR some computer-based editors for the Poly 800 II and Ex-800: SEQUENCER a very basic 256 steps sequencer syncable to external Midi clock.ĮFFECT famous chorus from original Poly-800 has been replaced by a 1024 ms digital delay at 12 bits resolution with some edit parameters such as wet balancing, time, feedback and a final 2-bands EQ. The chip is a resonant (but not up to self-resonance) bipolar analog 4 poles lowpass with cutoff and contour. LFO 2 delayed triangle-shapped modulators triggered by joystick control.įILTER a limited paraphonic filter based on a single NJM2069: whole mode: 1 x 8 voices for full polyphony.ĭCO an oscillator features 2 summable waveforms sawtooth and square + 4 additive harmonic octaves heights at 16' 8' 4' 2' + 1 white noice generator.ĮNVELOPE there are 3 EGs with ADBSSR segments, wich stands for: Attack, Decay, Break point, Slope, Sustain and Release. double mode: 2 x 4 voices for a thicker richer sound2
The OKI generates 8 DCO digitally controlled oscillators assignable in 2 different manners: Music oscillator DCO is based on a OKI MS-M5232 chip, best known as implemented on some early '80 arcade games (now emulated by famous MAME emulator). TECH main unit is a 8 bits controller CPU Intel 8085 family. Power supply is external PSU with 9V AC/DC -)+ polarity. Main panel features a segments display, 3 sliders, 19 buttons, 1 data slider and a pitchbender. Updated version of the classic poly-synthesizer Poly-800 with some new features and a better Midi management.
