ResidentSf2Synth: Error playing French Horn

[notator]

From WebMIDISynthHost issue #8:

Sending the default noteOn to
ensemble 1 / 000:060 French Horn results in the following error message in the console:

"Uncaught TypeError: Failed to execute 'setValueAtTime' on 'AudioParam': The provided float value is non-finite."

The French Horn works fine in the Arachno soundfont when used elsewhere, so I think this is a bug in the Sf2Synth1 code.
.......
I seem to have fixed this. See soundFontSynthNote.js lines 200-205.
The original line crashed, not unexpectedly, when initialFilterQ > 0 (which was the case in the French Horn preset)
The fix seems to work, but is it really correct?
........
Is this related to issue #1 in SimpleSoundFontSynthHost?

I changed the soundfont from "Arachno1.0selection-grand piano.sf2" to "TimGM6mb.sf2", which is a full GM soundfont. However, the program only finds patch 60 (French Horns) to patch 127 (Gun Shot) in bank 0; in other words, patches 0 - 59 are missing. Probably there are some errors in the parser?

French Horns...
