Man, these are amazing! I've been thinking a long time which ones should I get after my Arturia MiniLab MKII broke down and decided to go with Nectar after a thorough consideration.
I regret nothing!
The instrument is robust, heavy, built like a tank. For this price (given it has 49 real sized keys), I was expecting something light, fragile and amateur. But... I've got a really nice, well crafted piece.
All controls are working (the arpeggiator is amazing!), the keys are nicely weighted, they respond very well and overall I couldn't be more satisfied. Keys have a ton of outputs that can serve every need one could have in studio. Also, the USB cable provided isn't a cheap short pos that usually comes with tons of instruments nowadays.
I didn't yet try the software out, because I'm stuck with a couple of ideas I am working on in Reaper and FL20, but that was a nice addition!
