how 2 transfer midi files i have in the PC to PSR 1500 or 3000 smartmedia drive fast?

Could you help me with this?

1) how can I transfer quickly the songs (midi files) i have in the PC to the PSR’s internal memory or to the smartmedia drive?

I’m using the file utility version 1.2 with a psr 1500, however I just obtain errors (device not found) I’m looking for documentation about this issue, but it’s hard to find.

Yamaha’s home page just mention the “file utility” but I does not show how to use it.

I read the file utility manual (pdf), and nothing seems to be wrong.

What i hope to find?
The keyboard internal memory or smartmedia drive will appear as a data drive of my computer inside the “file utility” program

Hi

The fastest way is to buy USB smart media reader for PC, connect it to PC and transfer all files to your smart media. Then take out SM from reader and plug in into your PSR.
Or also you can use USB flash drive plug in directly into your PSR.
