I wouldn’t recommend that..What program are you using to transfer your sysex files?Also check your USB cable if it’s in a good state and watch out if you don’t have enough available space..
Hi thanks for the Reply,I've managed to find the 1.4 OS file,as I had burned it to a CDRom sometime ago,so was able to use the older OS File,so have rolled back the Tempest and am able to reload all the old projects and beats back in with no problems so I shall save them internally first and then reload the Newer 1.5 Back in and dump them via USB once the newer OS is loaded,hopefully the files should be fine with the newer OS
I knew it wasn't the Cables or lack of memory in the Tempest nor the Sysex program I'm using to dump the sysex data,I've been dealing with Midi and things for 25+years and owned a large studio for a couple of decades so am confident in my trouble shooting with Music Technology,this is why I needed the older OS file to rule that out as the issue,which it was,as everything worked prior to updating the Tempest.
Hopefully once I've saved them internally and updated the OS the files should be compatible,if not then I will stick with 1.4,I had updated to 1.5 just because the file was available but had not experienced any issues with 1.4 so would be happy to stick with that if the files aren't compatible with 1.5
