After leaving M4A, the receiving app must support the streams encoded inside MIDI, not only its extension.

M4A to MIDI taking too long? Check available memory; long, high-resolution sources need substantially more.
MIDI converted from M4A not opening? Test a compatible player and inspect the output streams.
Match MIDI resolution, rate, channels, and codec to the published delivery rules.

When does M4A to MIDI conversion make sense?

It is useful when M4A media created for everyday audio delivery must enter a MIDI system designed for music-event exchange.

Where is the M4A source processed?

The browser prepares MIDI from M4A on this device instead of sending the source to a remote conversion server.
