I have just purchased an Alesis DMPro. The unit is one week old and I have used it only twice. The first time everything seemed cool, I was using one trigger for about 2 hours. The second time I had three triggers running and after 1 hour the module locked up. You could only play for about thirty seconds before it would lock, and then another 30 secs before a loud bang, and the same process was repeated. I have noted this problem on other discussion boards and it does not appear to be a formally addressed problem by Alesis. Has anyone else had, or heard about this. If so please post.
