I have tried saving with patches, etc. and to no avail, the harmony will change but not the patch on my Ketron SD2. With BIAB V. 12 I did not have any problem making these changes and songs saved with these changes will play perfectly on BIAB V.10. I hope that somebody from PG Music will answer my inquiry.
