The last 3 gigs[all outdoor], with my Trio..I have used my M-Audio Axiom61 controller..controlling my VST's on my laptop..The Axiom61 is a USB, 4 zone controller with a multitude of sliders , knobs, buttons, and pads..
I have set it up very basic for now[since I had trouble setting default sliders for drawbars..most likely human error], I set 4 zones , key range and program changes, along with CC7 for expression on pedal and slider #9..
The easy hookup [USB] is quick and clean[no extra wires or interface]...

I am set up[with Forte] to play my VST's..and B4 as a stand alone..I am playing my VST's live along with/and over MP3's, sequences[VanBasco player], and when needed , JammerLive[arranger]..
After 3 gigs with this set up, I am happy to report..no crashes or unexpected /or expected problems..

The Axiom61 has a semi weighted key pad, so it is comfortable to play compared to virtually all the synth action controllers I have tried..The fully weighted ones are too much for me, to use on long gigs..

The one thing that I am compromising on...61 keys, if Axiom had a 76 key version, I would go that way..I find my self going off the board looking for that low "E" bass...

Last night I played at the shore, and the fog moved in so bad[outdoors , remind you]..It was like soup..I had to continually wipe down mics, stands, keyboard, mixer, and laptop..

I was glad I was using a$300 controller, rather than a $3,000 G70..I would have called it if I was playing my G70..I wouldn't expose the G70 to that[against my nature]..

Overall it has been a pleasant surprise working this way with the Axiom61..I will let you all know how things work out as I set up the Axiom61 to do more control...
