«  Really »

The number of controls, sensitivity to touch and I decided automap. Both midi out and thru are a real plus. I use it but it can be very useful to others.

UTILIZATION

Touch is not bad. I am not a keyboardist, so I have little to give comparative.

The manual is short, too short.
With Cubase DAW best known and tested live) it's going well and quickly, malheureusment I use Reaper, and then have to search the net. A guy of the United States has a very functional plugin. For those that ca interress, look for "automap csurf plugin".
The touch sensitivity is really good, but must learn to manage it. Effeleurement selects any one function.

The pads are anecdotal. Too small, not sensitive enough. If you want to hit beats, buy a dedicated controller.
on the other hand, you can assign a keyboard shortcut in automap and AC is a good idea.

OVERALL OPINION

I use it for six months, replacing a chépukoi EMU (the IRONMONGER).
I like a death and the automap screen. Now I mix with more ears than eyes, and it really changes everything.
I do not like the integration with Reaper.

It's upscale, the price is high, but we are not disappointed.
