I played a little bit with MG2 Beta 10 and was impressed with the bends/sensitivity/performance......not 100% perfect like a midi keyboard, but very close. Also, the pitch bend depends heavily on which sounds that are being used. In Alchemy, I've started marking the preset with 5 stars on sounds that respond well to my playing as well as have tones/patches that I'd really like to record.
I'm still getting a MG crash when clicking on the Control Panel as well as that buffer size being too large message, but both are a non-issue at atm.
My goal is to use this in playing Bass synths (NI's J-Bass etc..) to back up my guitar work. If I can get it to respond properly/effectively by playing clearly, we're in business!! I'm very happy with the improvements and continuous updates with MG........onward to tracking next.
