well it's the roland xp-80 keyboard that I'm using 95% of the time as just a controller.

after running it through reason to rewire to protools, the playback is really jerky/sporadic.

sometimes it sounds good while being recorded but once played back it's terrible. I've been messing with the playback engine in protools using up to 90% cpu usage.

I don't know if there's much I can do about it in Reason.

I've been through the optimization steps for windows xp many times and I will have to upgrade computers one day but I don't always have this issue.
