After poking around in JAMIN's source code (gawd I love Free Software, and also being
able to code well enough to read the source and get a decent sense of what it is doing),
it seems that JAMIN uses an IIR filter to do the crossovers. It seems to be a Butterworth
biquad filter. So, since I didn't use the FFT graphical EQ, it's possible that no
Ceylons infiltrated my music.
Thanks, and sorry about hijacking the thread.

So, are the artifacts caused by the compressors
or the EQ?
The ones I referred to are caused by the FFT-based EQ.
I didn't use the EQ on JAMIN at all, just the
multiband
compressors and the final limiter.
I don't know if Jamin uses the FFT processing to implement
the bandsplitting for the multiband compressor.
If it does then the artefacts of this type of processing
will show up in the output.
If it doesn't, then Jamin needs some type of bandsplitting
fillters that add up to exactly the input if compressors
are inactive. I doubt very much if these are implemented
in Jamin.
