You are welcome, Ludu. I am pleased to say that I have now fixed the problem and the latest Beta Test (version 3.1.11) is now available.
I have also recorded a video, using this new version, that can be found here -
https://youtu.be/zA49LejRIdY which demonstrates the following:
1. Import a MIDI file from a 4 manual instrument that includes multiple pieces and uses the crescendo pedal.
2. Automatically divide this file into separate tracks that include all registration and expression changes.
3. Edit pieces using a simple graphical interface to change notes, registration and expression
4. Start playing a track at any point and mute/solo individual divisions
5. Playback the same tracks on St Anne Moseley without any editing or configuration changes.
6. Show how tracks can be played without editing on ALL major manufacturers of digital organs (including, for example, Rodgers) and on pipe organ control systems like Peterson.
7. OrganAssist can export any edited tracks as standard MIDI files for playback using the Hauptwerk player.
Any feedback or suggestions are welcome.
[Edit] I have a configuration for Melbourne Town Hall and a layout (without MIDI) for PAB. The PAB is on the download page of my website. I need to check the MTH over before making it public. It is a challenge as OrganAssist only supports 5 manuals! OrganAssist is designed so that it must have the individual stops or the track cannot be played on other instruments.
