UPDATE!!!!!!!!!!!!!!!!!!

Good news..

I eliminated the problem on player 1...if you recall I had a seq playback problem with sequences created on the G70..I surmised the player 1 on the Korg can not digest the data pak with system exclusive data..

I went into the preferences of the global-songplay and selected "fast play"..I believe this blocks system exclusive data..it now plays the G70 sequences ok...My guess ..player 1 was overwhelmed with additional data and it's added features.where player2 is stripped of the added features, and required less read power..

This weekend I will see if I still have the random stoppage of MP3 play while using both players..this happens several times during a performance..maybe a ratio of once every 20 tunes...I have never been able to reproduce this at home....Let's see if the "fast play" fixed this too..
