Hi i don't know what is error: "Wrong length value.". my settings:
`root@DESKTOP-3UO8B8V ~/midi2json # ./midi2json
MIDI file < a.mid
Suggested tick/Q: 3840

MIDI tick for Q: 3840
MIDI track for 5<> (0 to disable): 0
Ignore rests on MIDI track (0 to disable): 0
Wrong length value.
Перервано (збережено знімок оперативної пам’яті)`

It means that your midi file is not quantized. All delta times must be multiples of Tick for Q/256.
