recently tried to remix a midi song i found on the net anyone with info on how to do it on an 
mp-7 would be appreciated ie.

how to get the midi instruments on the mp-7 to sound right

bypassing the 32 bar pattern problem on a midi song over 32 bars
so that the mp-7 cc doesnt reset instruments after you have changed them to the voices you 
want

locating different instruments and assigning proper voices to them

anyone with tips has anyone succesfully taken a midi song off the net loaded it on to a  mp-7
and remixed it and got it to sound good any tips appreciated 

i don't  feel this topic has been fully explored but i would like to look into it further because 
of the great possibilities of remixing bass lines leads etc.

thanks hope you are not all very confused after reading this
cheers
