Hmm, uploaded a few midi files. It showed one building and then no buildings or anything at all below the play (stop) button. What kind of midi data is this expecting?
It seems to be expecting Type 1 MIDI files (with instruments on multiple tracks). It does well with those, but doesn't seem to split out notes by channel from a Type 0 file.
I got it to load one of my MIDI files, but the stock on they provide felt pretty glitchy. Do the sliders just affect the way the MIDI is visualized? Because it seemed to break the audio up on their default file, but didn't change anything with the MIDI I uploaded.
I just thought something was probably just broken on Firefox.
I also got this with a few files, with only one instrument, and low velocity. Try some songs with more "action" :) Still, calling it new songs, is stretching it, in my opinion :P
