TR8s midi send problem when quick muting many channels

[maskedrumour]

Hi, thanks for reading -

my TR8s send midi clock only to my Novation circuit (or monostation) via a direct midi connection; everything is synced just fine.

I found out today that when I quickly lower the volume of 5-6 or more instruments *at the same time*, the MIDI clock send signal just stops, or at least some trigger is sent so that my circuit stops playing. The same happens when I quickly increase the volume.

I have attached a (not so great) video of the problem.

Has anyone encountered this before?
