One of the first release in 1983 synth twelve o'clock, noon on off trs rudimentary (no sysex or control knobs) to synchronize arpggio I advise to do trigger a TR 707.
Tune Possde also a button to easily tune.

UTILIZATION

If you have some basic knowledge of analog synthse, we understand how quickly it works and the original manual is available everywhere on the net. Pdf.
Roland did a good job, everything is intuitive and easy to control trs.
Patches s'editent easily and can assign multiple presets for example moving from a same bass sound with or without LFO etc ...
The keyboard is splitable into two parts.

SOUNDS

This is absolutely the sound I was looking perfect for the typical 80's sound, powerful bass, pads captivating, no futuristic electronic sounds ... well as I'm a fan of new wave ...
I just wish a Sub.

OVERALL OPINION

5000 F bought secondhand. I use it for a year, it was my first synth it from the mouth with small red spots that flash ...
Trs robust and a bit heavy (15 kilos)
Too bad we will take the head between the MIDlet arpggiateur sync.
Qualitprix excellent, I do not change it for anything in the world against a JP-8000.
Needless to emphasize, I do not sell ...
