Yes, it looks like Elektron’s latest Digitone update breaks old sysex compatibility. From my perspective, losing backwards compatibility is simply wrong and gives bad indication of development process.
I managed to overcome this issue as I have 2 digitones. One of them running old firmware. Thanks to the older one, I managed to rescue the project. I will DM you the link!
I have also updated the links so future purchases wont run into this issue, until Elektron breaks it again
