Buggy behaviour: Cubase "Track Quick Controls" sometimes do not react


have you ever experienced this:

I’m sending CC controller value 0 and 127 in order to switch a MIDI insert (in my case “Transformer”) on and off.

Works most of the time but sometimes it does not react resp. I have to to send the midi message twice. Also, if I’m switching quite fast***** (I send the two CC values by hitting drum pads) it won’t react consistently (some messages are simlpy left out).

[***** example: three messages ON-OFF-ON in about half a second or little below]

Checked with a midi monitor: the two MIDI messages (CC value 0 vs. value 127) are sent without any issues!

There is no difference regarding this buggy behaviour comparing Cubase 7 with Cubase 10.
