UDO S6 Desktop.  
Using the Mod Matrix (LFO 2 → Env-2R) seemed to work normally until I hit the patch button and lost the mod.  
Subsequently the only way I could get the mod to work was to hit the Mode button a few times, then I would just start working as expected.  
I’m not sure if I’m missing something and this is how it’s supposed to be, or if there’s a glitch.

Can confirm - came to the forum to check if anyone else has it. It’s one of the several bugs that I’ve noticed.

Steps to reproduce:

create some modulations in the matrix \> switch the patch with the Patch Preview feature \> go back to your original patch \> modulations gone.

Didn’t try hitting the mode button, will try.
