Description

Your idea

Add an option in preferences to disable guessing a key signature when importing a MIDI file.

Problem to be solved

MuseScore fails when importing MIDI files with chromatic or atonal music. It also fails to recognize a key signature in a dedicated metadata track, which is common in standard MIDI files.

MuseScore can continue to behave like now by default. But an option to disable this "feature" would be very convenient and wouldn't affect anyone.

Research direction

Start by locating the MIDI import handling and the preferences UI. Trace where key signatures are guessed during MIDI import and determine how an opt-out preference would be persisted and applied. Done means chromatic or atonal MIDI can skip key-signature guessing while the current default behavior remains unchanged.
