"Polyphony - 6 voices Oscillators - 2 DCO's per voice Memory - 32 preset, 32 user Filter - Resonant Low pass Effects - Chorus Arpeg/Seq - Simple Sequencer Keyboard - 61 keys Control - MIDI (no velocity except with a special ROM upgrade). Date Produced - 1983."
Anyone know about the ROM upgrade? There is reference to one for the MKS30 rack version here (via this post), but no mention of the JX-3P and no mention of velocity.
Update via haricots in the comments: "Here's the JX-3P mod"Update via nebula in the comments: "Actually that's probably not what he's talking about. A firmware upgrade was available from Roland that allows you to power up the JX-3P holding down the "7" button. Its own keyboard doesn't work, but it becomes a velocity sensitive MIDI module. Velocity is only routed to volume.
With the same mod, pressing "1" or "2" during startup gives you Roland's traditional "Poly 1" or "Poly 2" modes, including a little lightshow on the first 6 LEDs (Six-Trak style) to show you which voice is playing."
Here's the JX-3P mod > http://organix.inque.org/proj_jx3pexp.html
