Thank You very much to all of you for your support.
But I am completely lost.
Nothing is working in BIAB 2021 as far as midi is concerned.
I used the Open Midi command and the Import Melody from Midi File command and what happens in Melody and/or Utility Track is completely out of control.
I tried to return to factory settings as well as uninstall and reinstall BIAB, without any improvement.
Did someone of you really used those commands with BIAB 2021?
I have been using BIAB for more than 10 years and never had problems.
Now I am on BIAB 2021 804 and Windows 10 last update.
What else can I do?
Best Regards to all of You.
