Multiple instruments don't work in safari. about midi.js HOT 1 OPEN

believe it or not, I get rid of many problems like this by changing the order in which the multiple instruments were placed in the instruments array:

instruments: ["acoustic_grand_piano","some_guitar","synth_drum"] => nothing worked, NoteOn have played the wrong channel, other notes simply didnt sound, and the ctx.decodeAudioData failed (firefox) to parse the same base64 info that runned ok 30 seconds before...

changing to:
instruments: ["synth_drum","some_guitar","acoustic_grand_piano"] everything worked fine.....

i've spent hours trying to find out why, but i could not find a reason.

from midi.js.
