Well, actually, I have it connected to the computer and sitting on my keyboard. It works fine and would likely serve you -- as would anything equivalent. I don't use it because
1) it's a bit of a pain to set up
2) I'm a piano player and happy with a single sound for whole weeks

But if I ever need to tweak, there it is. Mostly it's there to convert midi to usb but at $50 used, the knobs were free.

Really, though, I can't recommend buying a keyboard based around its knob count. Action first, second and third and add the faders later.

A master keyboard with all the Pianoteq 5 controllers  ( MIDI note velocity off,  four progressive pedals  ... )  ...

Anyone?

I use a faderfox midicontroller to use the most important pianoteq functions. it's a small controller, easy to place it in front on the masterkeyboard

Anyone?
