TFMX ? No it's plain YM + soft modulation (SID, digidrums).
Certainly composed on his personal ST YM tracker.
Hippel had an especially fine groove on his latest tracks.
Also check his tunes "Virtual_Escape-End_Part.sndh", "Faith.sndh", "Buzzer.sndh", "AJH_99.sndh", "Solidify.sndh", "1.sndh" and "2.sndh" at : http://sndh.atari.org/sndh/sndh_sf/mad_max/
(and the /Demos/ subdir), in the same vein.
(and then, check "Cube!"'s work if you haven't yet, for more ultra blasting progressive grooves)
