Attempt to Configure MDP Connection on M1 Mac Midi

Question

MIDI Target Manufacturer(s): Other/Unlisted Maker

I was able to install MDP on my M1 Mac Mini. This is my initial report. I normally use the iPad to connect MDP to Hauptwerk Virtual Pipe Organ on my Mac via the WiFi connection using Audio Midi Network "my Session". I am attaching an image showing the iPad configuration (iPad to HW Connection). The HW Output Port connects to Network Session. Both Inputs and Outputs go through the Network Session. I normally use Midi Monitor to monitor the Midi data, but do use the MDP log on occasion.

I don't know how to configure the Mac MDP. I only get it to work in one direction or the other using IAC Driver, but not both. HW will not let me select IAC Driver for both Input and Output Ports. The image "Mac MDP to HW Connection" shows the Configuration I tried that only works in one direction. When IAC Driver is selected for the Input Port, HW responds to MDP. When IAC Driver is selected for the Output Port, MDP responds to HW. Any idea what I need to do to get it to work in both directions?

I also noticed that Labeling moves up when a button is selected. It will stay up, but when MDP is quit and restarted, it looks normal  again. See image 'MDP on Mac Label Offset". Compare the Trumpet 8 label to Clarion 4. Both labels should be aligned horizontally. Several other button labels are shown offset up.

I will test out the operation when I get the Configuration Setup properly.

We didn't have any luck using connections over Wi-Fi. We've also forced the "MIDI Designer Initiated In/Out" to ON for the M1 version. The basic question is are you able to get another app -- there's EasyMIDI for Mac, which has a demo version, to test -- to talk in and out to MDP2 on M1?

The other issue + the lack of support in TestFlight for current macOS makes us a bit jumpy. We might pull the App from the MAS later this week. You would still have access after that, just... don't delete the App ;)

Anyway, thanks for this Don, let's figure out the MIDI issues first.

Configure MDP to run on M1 Mac

I configured the MDP M1 Mac OS app to control the Hauptwerk Virtual Pipe Organ Mac OS app. To configure the MDP app to run on an M1 Mac using Big Sur, I use the following settings:

1. On the Mac, set Midi Studio IAC Driver to 2 Ports (I named them Bus 1 and Bus 2).

2. Set MDP Configuration to Bus 1 as the Destination and Bus 2 as the Source.

3. Start (or restart) HW and set its Input Port to Bus 1 and its Output Port to Bus 2.
