I am currently suffering from the same dilemna as all of you. I have checked the driver. Not the problem. I have hit midi reset. Works for making waking Halion SE up and allows notes with my Akai Mini to be played, but crashes as soon as it is expected to play a midi note I’ve recorded. I’m just using one program, the Musette 2 patch. The outputs are activated corrected and the inputs and outputs are correctly set up. So what gives? I have to tell you it has been a frustrating day. I’m in the middle of a project and didn’t need this today.
