Was just trying to set up some new buttons using Cubase MIDI 3 or 4 target app, but the buttons only send on the normal MGP midi channel even though I’ve chosen the correct target app in the button settings.
Older buttons I’ve already made send properly on the target app for MIDI 3 or 4, but nothing I make that’s NEW will send on any of the extra Cubase MIDI apps.
Thank you for reporting this and for clearly distinguishing the behaviour of existing buttons from newly created ones.
The MIDI-routing problem affecting new buttons created for Cubase MIDI 2–9 and Cubase Sync has been fixed in MetaGrid Pro 1.7.6, which is now available as the production release for iOS/iPadOS and Mac Catalyst.
Production announcement and release notes:
The later question about fader routing is separate from this button fix and is not part of the 1.7.6 hot fix.
