Configure MDP for Mac to run multiple instances in Mac OSX

Question

MIDI Target Manufacturer(s): Other/Unlisted Maker

Some Mac OSX applications can run with multiple instances of the app. MDP does not. Other apps, such as Excel can. The procedure is to use Script Editor (or Terminal) to create multiple versions of the same app to run. To begin with I had to rename the .app in the Applications folder to remove the space between MIDI and Designer to get the Scropt Editor to recognize the app.

Executing do shell script "open -n /Applications/MIDIDesigner.app" resutts in error " LSOpenURLsWithCompletionHandler() failed with error -10670." number 1 when an instance is active,

I am able to execute successfully for Microsoft Excel.

Is there a way to configure MDP to run 2 instances at one time?

BUMMER!  Maybe could run a mac OS version with an iPad together? I will have to check it out. Later.

Thanks for checking.

I think TF runs on macOS 12 so you should get two mac versions that way.

TestFlight so you can run Next & Pro

Great idea. I was able to open both. Have to find how to interface both to Hauptwerk.

Does MD Next have the plug-in?

Thanks, Don

I have been able to use MD Next with MDP2 at the same time on my Mac. Makes comparring 2 versions of a layout easy. Have to use Config Mail Layout to move layouts back and forth. MD Next has the plug-in. I have had a few issues with the Mac version. Will report later.
