I am looking for a small sized midi controller to controll mainstage including VST's and ipad apps.. (My previous one a novation nocturn just broke down)

I gathered some video's about my current interests HERE

Currently the models :
Samson Graphite MF8
Akai LPD 8
Korg nano Control 2
Arturia Beatstep


Anyone using one of these models, that would like to share his experience overhere?

I have the Korg NanoKontrol2 and the Arturia Beatstep and added led feedback for the 2 models in vArranger

The nano kontrol is very compact, lightweight and offers a lot of controls

The beatstep adds some features like infinite knobs and internal arpeggiator. big buttons etc.. but not sure if compatible with mainstage, as I had to create a special mode for it in vA

I own the Nano Control2,, I set it up to use with Mixcraft 7 Pro, I wanted it for drawbars for Native Instruments B4.. but the problem, sliders are too far apart, not comfortable..
It does work great and is on the top of the list posted..

Mine sits in the box..not being used..

I decided to get a touch screen laptop.

Even with a touchscreen, its good to have some rotary encoders (knobs)

virtuall sliders and buttons work quite well for me..

virtuall knobs dont thats where a controller excells

Luckilly i could lay my hands on a used Novation nocturn, small and adds 9 encoders and 8 buttons...
