I have 2 of the td50 modules, and I’m interested in downloading and upgrading to the td50x. My questions is, do I need to pay for it twice? As in per module? Or can I buy it once and use it on both modules?
I think the update needs you to make a Roland account and will probably ask you for the serial number of one of the modules to get the download file, but I think once you have the firmware file it probably won't be tied to the serial number. I think it would be a generic firmware update process that would work on both modules, but I don't own a TD50 and this is just an educated guess. The only way to know for sure is to try.
