AR mk1 hangs on sysex receive

Hi, I’m having this issue when I try to send a soundpack to my analog rytm mk1. It just hangs there until I power it off/on.
Anyone has solved it?

I recommend that you make a support ticket on Elektron’s website.

Hi Peter, I already did, I wanted to ask here because I assume it will take a few days for them to reply. Thank you!
