Enabling MIDI Audio Console crashes Resolve on startup

PostThu Apr 26, 2018 1:13 am

Steps to reproduce:
1. In Resolve>Prefs>System>Control Panels enable Use MIDI Audio Console
2. Restart Resolve, get a crash on Loading control surfaces

Reinstalling Resolve with different components does not fix the issue since uninstalling Resolve does not clear the preferences.
Having MIDI controllers connected or installed in a system does nothing as well.

I've noticed that removing preferences folder allowed Resolve to launch normally after reinstalling it, so I dig deeper. Looking into the memory dump file (with VS2013Ult) showed C:\Windows\System32\midimap.dll on the last row, which was also mentioned in logs apart of other errors, so I recalled what setting could trigger the issue and searched for midi in config files and found it inside Fairlight config:
C:\ProgramData\Blackmagic Design\DaVinci Resolve\Preferences\Fairlight\System Parameters.xml
where the value on a line with "MIDI_CONTROLLER_ENABLED" should be set to 0 to disable MIDI Audio Console. After this Resolve will work fine.

Windows 10 Ent. 1709 (16299.125)
Resolve 15.0.0B.030


I believe this is the part of the log in question:
