CC midi LFO's to external hardware bug

Hello everyone,

Sorry if this topic has been already posted, but i really don't know how to formulate this issue (my english is limited).

I am sending CC midi messages to external hardware. For modulating thoses messages, i'm using LFO's. I've been using the native LFO That is included with Max, LFO Midi that i found on maxforlivedevices, and LFO 2 by Robert Henke.
But the same problem persists : when i'm using more than 3 lfo's mapped to three different values, the midi notes are beginning to acting weird. Seem to changing the measures of my pattern, then glitching. When i stop my midi notes output, it continues. When i close ableton, it continues. The only way to stop this madness is to unplug the midi cable of the hardware. (and even sometimes it continues when i put the cable back in)

That said, this issue don't appear when i am using CCmapper https://maxforlive.com/library/device/5109/ccmapper
it has a feature to apply lfos to my cc messages, and i can put like 6 of these. No issue.
Except that this device don't recall the labels of the CC values : unlike MIDI+knob that i found on maxforlivedevices also.

This bug was appearing with a Tanzbar.
I also tried on my dominion club, same issue.
also tried on my micromonsta (which is not analog) same issue.
i've tried another output from my audio interface : same issue.

audio interface : fireface UC
operating system : windows 10 latest release
ableton 10.0.2

Have a good day, and thanks for reading it
