5 octave keyboard with pitch + modulator.
2 output jacks (left and right) + 1 headphone output.
Out / MIDI In, Out, Through.
Sustain pedal input
128 basic sounds (Bank A and B) Internal + 64 sounds like "ingredients" with which you make patches (64 x 2 banks) or by merging two basic sounds (Dual) or split the keyboard into two.
Sounds are obviously edited (otherwise it would not be a synth) so little practice elsewhere (system menu and sub menu ... Take your time!), Unless you use an editor Pc! !
The basic sounds Bhen is kind pouet pouet klingkling ... (I mean the basic sounds, no patches). I agree with other opinions on this synth, the basic sounds are not realistic and frankly not aged (there is the same on toys for kids right now) ... There's cons by way to make fun patches!
The polyphony on this keyboard is 32 notes (which is not bad anyway).

UTILIZATION

The setup is simple (y'avait nothing complicated at the time), however, better to have full manual (even for a self-taught) to benefit 100% of small subtleties of the beast.
Editing ... Bhen is pure digital era, no knobs -> no real-time control (except TFW via Midi on pc?. Publishing is fastudieuse! It features 4 oscillators using synthetic LA (Linear Arithmetic).
The internal PCM samples are poor, in addition to their length decreases or grows according to the notes (a little annoying for the agreements).
The manual is clear and everything is nicely explained and downloadable on the website of Roland in French.

SOUNDS

To the point of view patches, there's way to make things nice, very interesting.
The synth is not really made for electro cepandant it sound all its own, unique (sounds a little power). I have created patches that is very similar to the layers used in the "Big Blue" by Serra, but also an organ sound with the "what I'd say" Charles R. (Bhen yep) and I'm sure to be far from having been around this synth.
bass sounds to the "New Order" in 80's.
At noon, it tends to drop a bit when we are bombarded with information, but it never crashed.
Which is a shame is that we do not use patches Paut in multitimbral mode.
Of course, one can use multiple sounds on one channel, but that does not give the same effect as patches (no actual fusion of sound).
As against the keyboard is splitable at Noon (lower and upper) of 9 Parties.
You can use the drum kit as drum machine (programmable, but a little boring to program!) And no way to edit the sounds of the drum kit.
effects (delay and reverb) are not the most beautiful I've ever heard.
I could compare it to the effects it had on the play station one (roughly speaking, it sounds digital Aie Aie Aie late 80's).

OVERALL OPINION

I use it for a year, I bought it for 100 euros on an auction site world famous ...
What I like least are the menus and the fact of not being able to tweak the sounds in real time like an analog or analog modeling and also the edition that goes on.
What I like most, the possibility and also the sound quality anyway (provided you do not use the patch of origin). Yep Because the patches are like the original basic sounds "old and ugly" for most.
There's these things hetniques haha, pfffff ...
on the other hand sounds a bit like film music to John Carpenter.
You can buy cheap for the expansion card d10 PN 01 or 02, 03 etc ... This will help you draw some Ingredients interesting.
Before buying it, I used analog synthesizers (juno jupiter 8 and 106, old and new style arranger korg casio and Roland groove box).
Value for money, very interesting 100 euros for a synth!
I would do this choice, of course for the price, because finding a synth cheaper than that ... does not exist.
What is certain is that for that price, I will not let go!
