I bought this keyboard because I had a Roland GR20 guitar for me, and I did not need a master keyboard ...

USB (very convenient to connect on computer) MIDI (also very practical to connect the GR20)

There's also the input for external pedals, but I control everything from the gr20 so I do not use them.

UTILIZATION

So I trained pianist ... and touch is trs trs Different. It's better than a synth, but difficult to compare a piano, even bad. Especially since the keys have a strong tendency "hang" a little bit. Trs is minimal and does not impede the game, but a disturbing ...
I biensur AIM better feel, but that price, I knew what to expose myself.

The configuration is fairly simple. There There's just two or three things to learn if we can push a little the config (channel selection, ect ...) but still simple. It just needs a little guts to say what we do.
The manual is clear trs, the only thing I still do not understand is the use of the keyboard as "adaption usb / midi", which I would trs useful since I have patched the GR20.

OVERALL OPINION

I use it for several months. I like his point, its ease of use ...
I tried a lot of MODEL in fact, none of this range, so to compare, it is quite difficult.
Report quality price, quite excellent ...

While some tips ...
As for the GR20 (PDAL Originally Designed for electric guitar, playing the synth with the guitar, especially in my case, a godin XTSA) and of the use of KS88es with is simple (it works right away) and then they can just walk in CONTRL ... and it was the quality of its high-end Roland, so that happiness ... And bonus, it can control two or three things from the guitar (like volume, the sample set chosen ect).
Comfort and sound quality ... gnial absolutely. What's more, possibility to connect the usb at the same time, and therefore use the banks of the computer, or software that modulate or craient images based on a MIDI instrument. ..

Real stuff after all ...
