My SD1 has 4.0a installed. I try to install 4.0c and it locks up. Is it necessary to first install 4.0b or is it possible to install 4.0c over 4.0a?
Thanks,

Don, I'm maybe totaly out on the fields here, but I seem
to remember looking into the website that there are two
different updatefiles, one for SD1 and one for SD1+.
Just striked my mind if there could be a mixup in files
downloaded?

Don,

There are 3 versions of 4.0c for the SD1. On the Ketron download page, if you scroll down a little bit to the 4.0b release, you will see a better description of the 3 different versions.

(1) SD1ORG_40C.exe
(2) SD1STN_40C.exe
(3) SD1PLS_40C.exe

Assuming you have 4.0a installed along with the 4.0 new sounds. Then you should download file number (2), SD1STN_40C.exe. Once the file is downloaded, run it (SD1STN_40C.exe) on your PC and unzip the content onto a formatted floppy disk. Take the floppy disk and insert it into your floppy drive in the SD1. Turn on the SD1 while holding down F6. It should load all the files and update your SD1.

If this still fails, you might need to load 4.0a again. Download all 12 files and follow the 4.0a instruction on the website.

Thanks for the help. I've been so busy that I haven't taken time to try again yet, but I will soon.
