Hello,
I am trying to set up MetaGrid Pro with Cubase 15 on Windows 10, but I have encountered a problem with the Selected Channel integration.
My setup:
- Windows 10 PC
- Cubase Pro 15 (latest version)
- iPad Pro running MetaGrid Pro
- MetaServer running on Windows
- loopMIDI used for virtual MIDI ports
The problem:
After adding Selected Channel in Cubase MIDI Remote Manager, it appears to load correctly. The device shows as connected.
However:
-
After closing and reopening Cubase, the Selected Channel device disappears from MIDI Remote Manager.
-
The Selected Channel interface inside Cubase shows many functions, but they appear inactive/disconnected.
-
On the iPad side, MetaGrid Pro does not show the Cubase plugin list.
-
The plugin page previously showed:
“Couldn’t load plugins - timeout”
Things I have already checked:
- MetaServer is running correctly.
- MetaServer shows green check marks for the integrations.
- Cubase MIDI Remote Manager can detect Selected Channel.
- Selected Channel has been added successfully.
- MIDI input/output names were configured according to the MetaGrid instructions.
- Commands and Selected Channel were tested separately.
- There are currently no JavaScript errors in Cubase MIDI Remote Console.
Previously I had a script error:
TypeError: undefined not callable
(property 'accessSlotAtindex' of [object Object])
but this error no longer appears after reinstalling/reconfiguring.
My current suspicion:
The biggest issue may not be the iPad connection itself, but that Cubase is not saving/persisting the Selected Channel MIDI Remote device.
Because every time Cubase restarts, Selected Channel disappears, it seems the integration is not being permanently registered.
I am also going to test with an original Apple USB cable for the iPad connection, although I understand MetaGrid Pro normally communicates through MetaServer/network rather than direct USB MIDI.
Could anyone advise:
- Is Selected Channel supposed to remain permanently in Cubase MIDI Remote Manager after restarting Cubase?
- Is there any additional installation step required for Cubase 15 on Windows?
- Is there a specific file/location where the MIDI Remote device registration is stored?
- Are there known compatibility issues with Cubase 15 + Windows 10?
Thank you very much for any help.
