Midi files with stops encoding for Organteq

My questions:

(1) Can one find on the internent midi files for organ which also encode (and play in real time) the stop configurations used by the organist during the recording?

If yes, I imagine that such a file will sound correctly only when played with certain presets (which contain all the stops used during recording).

(2) Does the midi file obtained by recording a piece played in Organteq contain the stop combination encoding ?

Hi Andrei,
I'll start with question 2:

Yes, the MIDI files recorded with the standalone version of Organteq contain all the essential information about the stops used and the other controls accessible via the (main) GUI. All changes made during playing are recorded.
This information is stored in the MIDI file as short SysEx commands.
You can find the meaning of the SysEx commands used here:

However, the MIDI files with the contained information will only sound correct (as they did when recorded) if the same Organteq preset is selected during playback, because the SysEx commands do not contain information about the pipe type, tuning, etc., but only about the position of the respective control on the GUI.

That brings me to your first question:

I don't know if there are MIDI files with information about stop configuration available online.
The MIDI specification doesn't include specific commands for organs.
Each manufacturer defines these mappings themselves, or the user creates them according to their own preferences.
This also works with Organteq, since you can link the stops to Note-, CC-, or PrgChg commands and save and share the corresponding MIDI mappings.

Universally playable MIDI files that are equally applicable to Organteq and, for example, Hauptwerk or the VSL Rieger organ, do not exist.
