I have a Novation 61 SL MK2

The new version of vArranger is working very good with this keyboard.

I can play and control 16 vst instrument. The mapping is very easy.
You can control every VST parameter.

And something very nice, You can get a full led feedback between the VST and the controller.

SO if you move a slider on the VST, you can see the led ring of the keyboard moving. The same with led buttons....

I will do a video soon to show you.
