Hello to you all,

I installed the new MM 2026 Premium replacing the previous 2025 Premium, Win 11 24h2, i9 12900k, 32gb ram, 2 audio interfaces with proprietary asio drivers.

I have this problem: I have a new Nektar impact LX Mini USB midi keyboard that I selected in the MM 2026 settings as an input device to play chords, melodies etc.

I would like to use the same keyboard with its internal arpeggiator.

But when I go to the MM Tab for synchronization and select the LX mini as a slave, Music Maker tells me that the midi port is already in use by another application...

What can I do to correctly configure my keyboard to send (or receive) synchronization signals to MM?

Thank you in advance.
