Channel 10 incorrectly loaded as drums

See original GitHub issue

midiconvert used by Magenta.js seems to consider both channel 9 and 10 as drums (as per General MIDI 2), so when loading a MIDI file with urlToNoteSequence, notes in channel 10 will have isDrum == true. This is inconsistent with the behavior of Magenta, where only channel 9 is loaded as drums (as per General MIDI).

Among other things, this means that MIDI files created with Magenta and containing more than 9 non-drum tracks will be loaded incorrectly in Magenta.js.

not sure how that got in there, but just changed it to only channel 9. fix should be live in @tonejs/midi@2.0.11

magenta/music seems to use midiconvert for loading the MIDI files, which, I guess, is an older version of Tonejs/Midi? So is it really fixed? (I haven’t tested it recently.)
