Description
The current alsa sequencer lags a lot and even loses events where there is a lot of controllers. The reason is one port is open for each controller. Multiplexing solves this problem (and also makes it mmuch more manageable).

As a bonus it connects automatically (based on names and not on port numbers).

Research direction
Start by reading src/core/midi/MidiAlsaGdx.cpp and the linked issue context to understand the current one-port-per-controller design. Define done as multiplexed ALSA sequencer handling without lost events under many controllers, with automatic connections based on names rather than port numbers. No test or additional entry point is mentioned, so identify the relevant MIDI tests or manual verification path while investigating.
