At measure 137, you might (won't) notice that instead of using the high pass filter I opted to use samples of the instruments high passed. This may seem overcomplicated, but if you try to high pass an imported sample, instead the player will make it high pass to a very high frequency (making it sound like a screech) and the composer will sound fine.
Basically, this is a bug and it should be resolved.
