Hello Doug,
Do you mean that you aren't actually able to auto-detect MIDI stops to virtual stop switches, or that stops which you had previously auto-detected (i.e. whose previously-detected MIDI settings were in the backup you restored) are no longer operable from MIDI?
Why did you restore the v6 backup? For example, was it because you had v6 running on a different computer? (If so, then the MIDI ports may be different on the new computer, so you would potentially need to enable/tick the relevant MIDI IN and MIDI OUT ports in the appropriate rows, or even auto-detect everything again if your new computer has less/differently-cabled MIDI ports.)
On your v7 computer, please first:
- Reboot the computer for good measure.
- Go to the "General settings | MIDI ports" screen, and make sure that the correct ports are ticked on the 'MIDI IN ports' screen tab (and also on the 'MIDI OUT ports' screen tab, if your MIDI stops are solenoid-actuated or illuminated).
- Now load the St. Anne's organ.
- Right-click on (for example), the Great Trumpet 8, and try auto-detecting it to one of your MIDI stops.
Does that work properly?
