I had 241 Preset in B – but even when I Bypassed B 5226 still crashed.It also crashed with only the H8000 running (no Octatrack).
Somehow I got it (5226) working again – by starting with custom Preset of 5226 I had saved a week earlier. I also started a new Project in my Octatrack. I am using lots of Midi CC’s to control the 5226 parameters with my Octatrack.
Now before trying to sample something new with my guitar I turn off Midi and Bypass Machine B on the H8000 and clear the sample that I had saved earlier. Then when I finished recording I turned on Midi with all the CC’s running and it has been working without a glitch ever since I started with that custom Preset of 5226.
