Just got the DTX 500 and am thinking that some of the features of my ancient DTXpress might not be possible with this newer module - hoping someone proves me wrong. The DTXpress would allow you to record a drum part as a user song, then start/stop the recorded song by hitting a selected pad. The DTX500 allows you to start/stop SOME songs (45-63, I believe) using a pad. The problem is, these songs that you can assign to start/stop with a pad (songs 45-63) are Yamaha created songs, not the user songs that you've created. Is there any way to trigger start/stop with user created songs? It was a fairly useful feature that let you play extra percussion parts during a live song when needed and I hate to think they left it out. Thanks!
