RME Midi Note Problem

Hi all, my Voyager RME allways plays the same note regardless of the keynumber sent to Midi-In.
In other words: Byte 1 of note on/off message doesn’t affect pitch.

Normally the Midi-In is connected to the Midi-Out of my Elektron Monomachine but I reproduced the behavior also with my Novation Controller and Logic.
Curiously the filter cuttoff frequency is changing as expected depending on the keyboard amount setting and other messages like CC or ModWheel are also processed well.

Recorded (with snoize.com/MIDIMonitor) on Midi Through Port of RME while hitting different keys:

Time            Source         Message   Ch    Data      
19:45:09.248    From Port A    Note On   13    48  90
19:45:09.424    From Port A    Note Off  13    48  97
19:45:10.960    From Port A    Note On   13    72  110
19:45:11.067    From Port A    Note Off  13    72  127

My Settings:

Local Control: all on
Midi IO: both on Ch 13
Running Status: tried Yes and No
Midi Merge: No
Midi Prg. Change: receive/transmit on
SysEx Device ID: 1
Midi Key Transpose: 0
Midi Key Order: Max Keys: 1 and Active Key: off
Release Function: Yes
RME OS Version 3.5 Boot Version 3.5
Env. Gate Switch: KEYB.

After 12 hours of experiments and searching for similar problems in this forum I’m on the verge of downgrading the firmware :frowning:

Many thanks in advance for any advice!
