Mac OS Sierra
Even though the scripts seem to work fine on Mojave (MacOS 10.14), severe problems have been detected on a MacBook with Sierra (MacOS 10.13) installed (which has been identified thanks to a customer from the US). The error could not be reproduced on a Sierra-VM, though.
Data Directory for Audio Files
In Reaper it is possible to define a dedicated directory for the audio files in the project properties in order to separate the project files from the audio data. However, the MuCol-scripts can not handle this setup - so please do not apply this feature.
Session Strings Pro (Native Instruments)
Track has "Session Strings Pro" loaded in the "Kontakt"-plugin from Native Instruments. Track is marked with ">C" (copy tracks to instrument-project or vice versa) and project processing is launched ("MC-PP").
Reaper crashes half way through the process.
Save the setup in Kontakt (multi), remove the "Session Strings Pro", launch "MC-PP", load the saved multi in the copied track. Or replace the sound with e.g. "String Ensemble" (if available).
This problem occurs with the version 11 of Komplete.
Working with subprojects.
While it is possible to create backtracks from tracks holding subprojects, it is not possible to copy those tracks to or from instrument-projects (">C").
Create stems instead of subprojects or create stems from the subprojects.
Starting new project.
User is asked to save project.
Save project before using the MuCol-scipts (ToggleIndicator or ProcessProject).
During setup the buttons used to launch the MC-scritps are setup in separate toolbar.
The predenfined menuset "MC_Toolbat.ReaperMenu" which is provided by the installation package only works with the "Toolbar 16". If you try to import the menuset into another toolbar an errormessage is desplayed.
Use "Toolbar 16".
