I recently tried out a setup using my laptop, my P250, OMB and HyperSonic 2. At first this didn't work very well, I had some problems with dropouts, inconsistent playback speeds and weird midi behavior. I first thought it was my laptop that lacked the juice for this application, but it was actually due to a registry configuration for the MIDI-Yoke driver. I found a fix at the MIDIOX website, and I now it works flawless! The sounds of HyperSonic 2 are great! And the program changes are almost instant! I'm currently looking into building patch maps to be able to use all the great sounds of hypersonic from OMB and sequencer software, and not just the GM bank, don't get me wrong, the GM bank sounds awsome, but there are many other patches that sound better in HyperSonic!
If I get this setup up and running, this will replace my live arranger setup!
