I have a JV90 I will not present here was very well done in the data sheet.
Basically it's a keyboard with some variety of sounds which has the advantage of having a 76-key keyboard which is INTERESTED in the scene.
Polyphony 28 notes -> Important patches consist January to April tones that just reduce your polyphony 7 notes.
The performances contain 8 patches (one for the battery) as well say that to a full arrangemet the JV is quite unrealistic.
no sequencer edition possible thanks to WinJV PC -> it works super full of Hell
Philosophy Roland regulars will feel at home.
Very easy to use even with the display 2x40 characters
The pianos, brass, guitars and strings are rather nice, for cutter in terms of the organ is a little hard drive ...
You'll have full editing functions with a bit of grip you can get to create your sound completely. We must recognize that aging is a machine, the synth sounds ideally suited to 90 years, for conntre for contemporary music is a little death.
I use it for 7 years it works very well but like all synths of that time, the comparison is difficult with what we do today.
If you do not have too much budget, here seems a good choice for a keyboard to do everything.
If you are really INTERESTED mine is for sale
