Bugs? about uncategorized meta-events

Hello! Thanks for making such a nice module.
There seems to be a bug where lines 263-264 in main.js (commit 310b076 on 11 Mar 2021), which read a file twice as long as metaEventLength.
Among the MIDI files I have, there are files in which an error occurs due to the syntax. I corrected the above and it was solved. I'll send you the MIDI file if you want. Please provide your contact information.
