The keyboard touch is not great, it is still there even DYNAMIC TCP and aftertouch (the common era), but the force is badly restored, it is better to order it from a keyboard master to assay the dynamic ... I collect will be used as a master keyboard for an expander!
For everything else, the quality is OK (stronger qu'aujourdhui)
8 note polyphony (the standard era) but analog and midi .... short, it is not so common a good analogue, polyphonic, dynamic, program and MIDI.

UTILIZATION

It is a polyphonic synth (8 marks at the same time) but if we use the unison mode (very big sound!), Polyphony is divided by 2 ...
Monotimbral against it by (one's time, a single midi channel ...), so it's simple trs.
The edition of the sounds is very easy (I learned it), you just need some notion of analog synthesis. Moreover, it is necessary because the 32 internal sounds are rather void.
I never had a manual, never missed my ca ...

SOUNDS

JX8P sounds are typical of the era of analog ... ca is the cost of programming, you get a great sound ... (Bass acids, tablecloths, lead ...)
As against it is a bit limited ... it is difficult to have a lot of variety with a simple programming ...
There is no internal effects (normal the era) and it blows a lot with some sounds ...

In short, Excellent sound, but some limited styles ...

OVERALL OPINION

Excellent for a synth programer easily (there are apps to program and store the sound) of sounds typical of analog of this era ....
Trs is limited (no external sound from a few modulations ...) but the filters are missing as to why the synths DCNI follows.
A single sound but what a sound!
The keyboard is not trrible, and it blows a little.
Trs simple, basic view, but irreplaceable if you can not afford a legendary Oberheim synth, moog, ect ...
