AJ,
the new release of 3.0 Upgrade (the release after 21 March) fix only the Delay or other little bug ?
I have reported to Ketron a problem with a new function added in the last
upgrade at SD1.
The function is the possibility to scroll through the Folders of the
HD using the Drum Volume buttons: if you try to change folder while a
song is playing the keyboard say a "please wait" message and go in a
hang status and you must power off and on to reset this situation; the
function work ok if the keyboard isn't playing midi file.

Bye
