Hiya BIAB family

Still working on my midi's here and Running them through my yamaha mm6...so i'm in playback mode Right now
seeing how my Repairs are sounding through the keyboard after i've doctored them up in BIAB

Most are sounding very good....but i ran into a snag today...
one of the midi's are not playing the drums well on the keyboard...it sounds great in biab playback
but on the yamaha you can barely hear it ...like its way back in the distance..

things i've found so far...the original midi sounds this way as well...so it doesn't matter that i've messed with it.. so original midi sounds great in BIAB on drums....but not on my mm6

i've tried saving it in a different format...changing the drum kits in the sequence section.
so i'm stumped again..

can someone share a possible remedy for this drum problem on this midi...i'm sure i'm going to run into another like this i bet...i have a hundred and forty to go through...lol

thanks
