Tnx a lot for the input and info.
I was looking at the Novation Launchkey 61 or M-AUDIO code 49 w/pads simply because almost new unused items is for sale at local eBay priced quite low.
If I deside to try out vArranger, I will mainly use it to play "left hand chords", and buy a SD1000 as soundmodule.
A Lenovo I7-16GB Win10 is planned to be used as vArr host until a touchscreen PC arrive.
And, it's not for pro use, (I'm only a simple amateur you know...) it's just to have fun, explore and play all styles from kb.brands I dont have anymore.
