I've successfully managed to record from the Clavinova onto a USB stick, to transfer onto the computer, and to convert the file type into one compatible with Flickr (essentially an audio only video file). Then the plan was to upload it to Flickr and post it here to listen to, but I have fallen at the final hurdle - when uploading to Flickr, I get the message that the 'video is being processed' but nothing further happens.
This is extremely frustrating.
My music will have to wait for another day!
