leezone,
You should actually be EDITING styles once you have copied them from the USB stick into the USER STYLE's appropriate folder in the AUDYA's HD, and not directly from the USB stick. The design allows for one to playback styles found on an external USB device.

Bernie9,
You shouldn't have to EDIT the REGISTRATIONS before you can use/play them. Simply UNZIP the file you downloaded from Ketron with the X Registrations. Now copy these X individual Single Registrations from your computer into the AUDYA'S HD. To load the Registration, simply press the REGISTRATION button and AUDYA will display the Single Registrations that currently reside in your HD. Use F3 (NUMERIC=ON) so that you can instantly recall the REGISTRATIONS by their associated numeric value - OR keep NUMERIC=OFF and manually scroll through and press ENTER to load the selected/highlighted Register.

Hope this helps.

Did someone say SEQUENCER - at last?
