Been around studios for thirty years. The Keylab Mk II is the best MIDI controller I have ever used. Still, some improvement requests, or even a request for a premium product.
You guys are very very close to producing the ultimate controller
1] Motorised Faders - these are lacking, I had to sacrifice this to buy this controller. Motorised controlers that can be turned off would suit everyone.
2] General upgrade to the knobs buttons and sliders. Whilst these are not the cheapest tat, in fact they are fairly acceptable, they are not top quality. In particular the pots can be a bit crunchy. The drum pads cpould be more responsive too, the big knob could be more durable and chunky.
3] Improved VDU. Larger, perhaps touch sensitive, raised in angle so that one can see it better when playing.
4] Re-introduce the painoteq software, in order to guaruntee a great piano sound ouit of the box.
5] MIDI 2 capability
6] Provide some user resource for templates for major non Arturia Instruments - like Omnisphere, Vienna Instruments, East West, and other brands. Perhaps a user forum here to swap these.
If there were a no compromise premium product like this, with the fantastic software integration (and sounds) you already have, in the fantastic chassis you have, with the keybeds you have, it would be a world beater and would make it's way into even the top pro studios. People would be happy to pay for it Personally I would pay well over a thousand UK for this, happily.
Hope you can make this a reality
