詳細

Some midi files can't be played with Miditrail on ios/macos. The error message is: "The file is not a standard MIDI file".

Same files can be played with other players like Timidity. Are these types of files unsupported by Miditrail?

Thank you for your message. I checked the files in your screenshots.

SimCity 2000 (1993).zip

The error message is "File read error". MIDITrail's bug was causing this error. I will fix the bug in next relesase.

UFO - Enemy Unknown (1994).zip, Transport Tycoon Deluxe (1995).zip

The error message is "The file is not a standard MIDI file". This files is RIFF(Resource Interchange File Format), not a SMF(Standard MIDI File). MIDITrail does not support RIFF. So, MIDITrail could not read these files.

Workaround: I opened the file by binary editor, and deleted the 20 bytes at the beginning of the file. Then MIDITrail was able to read the file.

I found a tool called rmi2mid, which may help you.

Thank you! I converted the files with rmi2mid. Only issue is with Simcity 2000 etc., but that is expected at the moment.

I tried the new MacOs and iOS versions and all the files can be played now :) It works perfectly. Thank you for your work!
