nice!

But PHASEX always sounded to me (and felt, as I was playing with it) that at any moment it could do something crazy like throw a DC offset, to into an uncontrollable oscillation, or blow up my speakers, etc.

Perhaps it is not about a particolar DSP but probably you are using
one of the follow wavetables for one or more oscillators:

  <https://github.com/williamweston/phasex/tree/v0.14.97/samples>

Of course they are usable with any sampler/tracker/etc.

Here is a simple test with SoX:

for smp in phasex/samples/*.raw; do
        play -t raw -r 48000 -c 1 -e float -b 32 "${smp}" \
             gain -9 speed 18 repeat 1000 fade h 0.05 1 0.2
done
