The Roland JX-8P was a 61-keyboard 6-note, velocity and aftertouch sensitive polyphonic synthesizer released by Roland in 1984 to compete against the Yamaha DX7. In many aspects, the JX-8P delivers classic "fat" Roland synth sounds just like instruments as Jupiter-8, Jupiter-6, MKS-80 and the Juno-6/Juno-60 for instance. The forerunner of the JX-8P was the more thin-sounding, less MIDI capable, non velocity-sensitive JX-3P / MKS-30. The JX-8P belongs to Roland's last family (to date) of analog synths. Other famous members of this "family" of synths are the Alpha Juno 1/2 synths, the MKS-50, the MKS-70 and the JX-10.Programming was achieved either by means of a data slider and a silkscreened data table designating each of the parameters, or by means of a separate unit, the Roland PG-800 programmer.
