Should be fine if all you want is something to lay down notes. Plus its got the added bonus of having a couple of asignable mod wheels too. Only thing to consider is the lack of any assignable knobs or sliders which can come in handy for controlling parameters on your synths etc..
Anything will do for playing notes through your VSTs though so long as its got midi. I just bought a second hand 80's Amstrad keyboard with MIDI out for the same purpose, its super retro lol.
