Description

Enhancement Summary

I'd like to propose a setting that, when active, stops the song editor from automatically adding automation tracks with time signature and tempo information in addition to the clip itself.

Currently, dragging a MIDI file into the song editor automatically creates a new instrument track with a clip inside and three automation tracks for the time signature and tempo data. Since I usually don't want those automations, I end up copying the clip to a different instrument, then deleting all four of the generated tracks. Having this setting would solve part of this issue.

Implementation Details / Mockup

This setting could be a simple checkmark box in the GUI section under the General tab, or in a new section under the MIDI tab.

Research direction

Start by locating the song editor's MIDI import handling and the settings UI under the General or MIDI tab. The work is done when an enabled setting prevents imported MIDI files from creating time-signature and tempo automation tracks while retaining the instrument track and clip.
