Song reps convrt error (CPU ADRESS ERROR)

Hello, i work with a lot of pleasure with a mpc 1000. I installed JJ OS 3.07.

I have a problem : when i want to convert a song to a sequence. I get sometimes an error.. ratio like 1/4. very disturbing cause i lose some ideas..

-> TO SONG MODE
-> REPS TO 2
-> PRESS CONVRT


i try to save before i do the action.. thats my workaround.. but it pisses me really off, because sometimes i forget..

Someone has experience with this bug Or better workaround

detail error message..

Sorry dude, never experienced that error

Not using that OS - I always run the latest JJ OS - and never had that error. Do you have a non-Akai memory module installed?
