Using a second keyboard for expression maps

Hi, I recently Bought the Spitfire symphony orchestra and I noticed that there are a lot of articulations. I would like to have only one track for instrument and using expression Maps to chance the articulation while I play , is it possible to play with one keyboard and switch articulation with the other one?

Yes. I use a Korg nanoKey for just this.

So I have to Connect both keyboard and it should work?

Yes, just plug them both in, with the keyswitch keyboard set to the lowest octave.

You will want to include them both in All MIDI Inputs so they both get routed to the VSTi.
