- How long have you use it?

A little month

- What is so special that you like most and least?

the least: I would have liked nine "tracks" as the UC33
most: strength, quality of materials, engine

- Have you tried many other models before buying it?

I had a UC33 about a year ago, I was very disappointed, considering the price!
I also tried various keyboards / controllers, I liked the korg midikontrol, but I was not looking to have a special keyboard ...

- How would you rate the quality / price?

postage included 200 euros Thomann, who says better?

- With experience, you do again this choice? ...

eyes closed!

To update the firmware, use bome's send sx! it works great!
Many options are arranged especially for the display of LEDs (small dots, gauge, pan, etc. ...), which is handy, especially when used in a poorly lit.
It lacks, in my opinion, small "skins" on uc33 as customizable as the small white strips are thin, and then write directly on it, it would hurt the heart ...
