Hi All,

I have just had a reply from Ketron that may be of interest with this topic. If you use the GM for your midi file and then play along via the SD1's keyboard or a midi instrument i.e. accordion, then it is possible to change the sounds for the accordion without any button presses but via a sysex command buried in the midi file. I haven't tried them yet but the sysex commands I have been sent are:
1)F0 26 7B 30 00 01 F7 to switch to keyboard

2)F0 26 7B 30 00 00 F7 to switch to midi
The patch changes can then be inserted between the two sysex commands.

John Romero.
