MIDI files problem

[thepsyntist]

I downloaded a few midi files from internet but I get this error:
"Track 1 should not contain set_tempo"

[Conchylicultor]

Sorry about that, I had to create my own midi parser (midiconnector.py) because of python 3 compatibility issues. The one I have done is really basic so it only support certain type of midi files.

Hey ..i make it like this....first i download a piano midi..usually they have 2 channel tracks ..i copy the second one into the first (in fl studio) so its only one channel...then i export ....than import this in the software GnMidi ...after import i convert it to ASCII text...the text i save and open with notepad...than i erase the tempo marks and other stuff like its in the example midis that come with the code...than i save...put it back in GnMidi...convert the text back to midi ..and than i save midi and put it in data/midi and than the music generater will load it =) ..i know thats alot work ..but it works!

What kind of midi files should I look for? It always tells me SMTPE timecode not supported. Thanks.

Hello guys, I copied the "basic_rnn_joplin.mid" from docs/midi to data/midi, and also downloaded a few midi data in the same folder, but when I run "main.py", the error looked like this:

I really wonder why is that? Which folder is correct for midi training data? Thanks a lot:-)

@Eumi I ended up running GnMidi successfully as well and was able to exclude all timecode syntax. Now main.py recognizes original MIDI files. Looking forward to someone making epic updates to MIDI capabilities with Python's libraries soon so we all don't have to go through this trouble. @Conchylicultor this is still epic. Thanks for sharing your explorations!

@itsjsbrown - can you share a gist of updated code? gist.github.com

@littlethunder I do have the same problem,
If you find any solution please let me know
Thank's In Advance

@Conchylicultor Could you please release your midi dataset? Several datasets published on the Internet is not suitable for the midi processor.

[Conchylicultor]

@li-yuntao I'm sorry but I don't have the midi I downloaded anymore. I should also warn you that he current version of the code won't produce any good results. It was some failed experiment that I tried about changing the note representation.
