Disklavier

Hello All,
I'm so grateful to have found this group. I just bought a 1999 DGP1xg Yamaha baby grand. It has a DKC100XG that plays floppies. It also was upgraded at some point adding a CD player DCD1 which is piggybacked in via the midi and analog ports.(I think this fact will prevent me from using the Bluetooth adapter because the MIDI In on the floppy player is occupied with a cable from the MIDI Out port of the CD player)

I have only a handful of CD's and floppies. I'd be so thankful if you could tell me what I am doing wrong trying to create floppies.

I bought an external Floppy Drive an hooked it to the computer. I downloaded zip files in the the E-seq format from http://www.kuhmann.com/Yamaha.htm. The Debussy file had less than 60 songs. I unzipped the file and then dragged it to the external floppy drive. I'm using a 3M high density IBM formatted 1.44MB disk. After making noise for a couple of minutes, the disk appeared to contain the files. However, when I put the floppy in the DKC100xg, the window says "cannot execute."

I tried this from my MAC running OSX El Capitain as well as from a PC laptop running Windows 8. I also tried to do it with the MIDI files on the same website, but I think my DKC100XG needs MIDI 0 not MIDI 1.

I hope there is some obvious mistake I am making and you lovely people can walk me through step by step what I need to do differently.

Thanks so much in advance.

Michelle
