Thanks ever so much for your considerable help, John and Roger too.

I've sent emails to you both. But wished to acknowledge on Synthzone how helpful you've been.

I now (probably) need to wait until after the Saturday concert to upgrade the KN7000 from v1.3 to v1.4 &1.6 as despite the Jukebox 5 working brilliantly and not needing the special card-reader, the KN7000 refuses to acknowledge there is audio on the 1 GB SD (it's a plain SD, not SDHC). (Formatted on Jukebox 5). Unless the problem is that the card is too big or something.

I am hoping that I can upgrade the keyboard after next weekend's Concert, and then it will recognise audio.

Will keep you posted
