In the polyphonic case, most effects are never interrupted, we just play them out.
However, we can always start another clash/blast even though the first one isn’t finished yet, assuming there are still wav players available.
In the monophonic case, each effect becomes the new hum as soon as it’s started, so it can always be interrupted by another effect. In some cases we limit the number of interruptions per second though, since playing a new clash 20 times per second just becomes noise.
Is this the case yet, or do we still need to run the high pass filter?
So, it’s certainly possible to do the filtering in ProffieOS, however, I don’t know if people actually do.
Suggested starting point values:
#define FILTER_CUTOFF_FREQUENCY 100
#define FILTER_ORDER 8
Cool. Is this how you do it, Brian? Or do you run the filter in Audacity?
If I’m making a font, I’ll just filter it from the get-go.
I find no detriment to having the filter active in all configs anyway, so I just leave it on.
I’m almost at the point of just doing both of these. It barely ties up 1% of total file size, even less if you’re on a V3 board.
FWIW this tool will now do many of the things listed above automagically

Someday I’ll do part deux: advanced concepts. (mildly advanced)
So buy/get a poorly produced font, and this will clean it up and optimize it? Get out.
I use @NoSloppy ‘s font converter to ‘wash’ all of my fonts
Proffie to Proffie ‘conversion’ is a lifesaver.
