I *think* that's the case.

When I was using that system lightly, it didn't matter which ROM I used. Once I started pushing its limits with 20+ tracks, it would crash every few minutes of playback if the older ROM was installed.

With the new ROM installed it looped playback of a 24 track project overnight and was still going in the morning.

I don't really *know* why it was like that, but that's what it was.
