Roland built the JX-8P at the beginning of the 80's, as successor of the JX-3P.
It has a typically analogue sound, someone said: "I've heard it. Wow. It has the Voice of Heaven."
The ease of use makes it a simple and good keyboard for beginners.
Jean-Michel Jarre (France) used it in 'First Rendez-Vous' & 'Fifth Rendez-Vous'.
You can find the JX-8P even today in professional studios.
Andrey Kolomytzev from Zelenogradsk/Russia does experimental synthesizer music, he especially loves the rough sounds of the JX-8P. Andrey pushed me to fix my JX-8P aftertouch corrosion, he did the pictures showing the repair process.
The JX-3P has no MIDI SysEx functionality.
It can only be programmed with the external PG-200
or with it's own buttons.
But the JX-3P has a step sequencer the other JX synths
The MKS-70 is a double JX-8P in a rack (without keyboard).
Two tones are unified to patches, allowing new effects
like morphing or playing two different sounds at the same time.
JX-10P 'Super JX'
The JX-10 is the successor of the MKS-70 series.
It has again a keyboard and is a multitimbral multichannel synth.
Roland changed the memory organisation of the tones and the
SysEx data transmission is a kind of packed memory dump.
This makes it impossible to program with PC-JX8P.
Additional informations at: Super JX from John Brandwood.
The bank manager CPJX for JX synthesizers is available there
with lots of tones and patches.
