The Korg i2 did not read GM files, if I remember correctly. The addition of a "standardisation" of channel assignments has made it possible for more people to share music on many types of keyboards. Unfortunatly, your old Korg was made before the mad rush to standard midi files came about.
Channel 10 is drums. Period. No matter how many tracks .... if they are on channel 10, they will play a drum sound.

As far as loading from floppy ... it's more like "copying" from floppy to transfer data to the hard disk. The "load" command usually loads the sequencer. The copy command will put the floppy data onto the hard drive.

DanO - any quick words of advice for our friend here about loading floppies?
