Midi messages on cursor change

[alikthename1 (alikthename_)]

Hi!
I see that ardour 6.5 sends midi control channels on all channels, when I change cursor position or on loop play/stop like these (supercollider trace)

MIDI Message Received:
type: control

chan: 0
num: 64
val: 0

MIDI Message Received:

etc…

Is there a way to control this behavior (couldn’t find out in preferences)

This is a MIDI panic message: raise pedal (CC 64), all notes off (CC 123).
It is needed to silence synths when seeking on the timeline, otherwise there may be stuck notes.

No, this messages is injected unconditionally to MIDI tracks for all MIDI channels.
