Control via Midi unexpectedly triggers the wrong color from the second song

[Webworker]

Hi there,
I have a whole new phenomenon with my two Live QLC+ computers.
On the development computer I have stored several cues and scenes on the virtual console and control them from a DAW via the LoopMidi port.
(Development computer: Presonus StudioOne 5.5.1, QLC+ 4.12.4,
Live computer: Miditool MPS, QLC+ 4.12.4) I have the live system twice. One as a backup.

If I play a song from StudioOne on my development computer, everything works as desired. If I copy my .qxw file and the fixtures to the live computer, I start exactly one song without errors, as soon as I start the next songs, exactly the same lamp always lights up green from there. This then runs completely through all cues and scenes. If I completely restart QLC+, only the first song is OK again, all others then have the one green lamp again, although no single green lamp is controlled by Midinote anywhere. I can't make sense of it.

The same also happens on the backup system. The only difference is the DAW, but the MIDI files for lighting control are exactly the same as on the development computer.

The fixtures are 2 Eurolite KLS 3002 (4 lamps per bar), 4 UKing B54E and 6 B369 moving heads.
Windows 10 is installed on all computers.

Does anyone have an idea what could be the reason?

You could focus on the DMX monitor in QLC+ when this occurs.
Then open the project file and study its structure a bit. You will find the internal ID of the misbehaving fixture. Now you can go and find all the functions that control this fixture. Or you could start and try to find the value of the misbehaving channel of that fixture.
Be careful dough. Do a backup copy of the file. If you break the structure of the file, the project is broken.

Hi there,

I was able to fix the error.

I downloaded a midi monitor (MidiView) (https://hautetechnique.com/midi/midiview/) and looked at the data coming from the MPS software.
StudioOne only gives me note on/off data and everything works fine.
Miditool MPS outputs everything I don't need (pitch wheel, controller volume, controller expression, all notes off Ch1-16 etc.) and at the end of the song "Controller All Controllers Off: 0" is sent and then the 2. Lamp of the KLS3002 lights green and remains switched on from there until QLC is completely closed.
So I changed the corresponding settings in MPS so that only note on/off is transmitted and now everything works as it does on the development computer.

If someone should have the same problem, I'll just attach my two Midi-Monitor-CSV's here for illustration.
