Composer and the Yamaha DSR 2000

[Crochetty]

Hi Sherry
Thank you for your quick reply. I continued playing with the setup last night and eventually it worked, which was a relief.
However, I seem to have another problem: Having played a MIDI file through the keyboard I find that it is no longer possible to play it through the laptop's speakers (or extension speakers) - and in the latest example of this it will not play again through the keyboard either.
It seems that the act of playing the MIDI file through the keyboard creates some sort of change in the file so that it will not play through the computer (orm perhaps either) subsequently. If I close the file, however, without saving changes, it will play through the computer when re-opened. So it would be useful to know what is being changed when the file is played through the keyboard and whether it can be prevented.

Regards,

Crochetty
