Chromatic does not refer to "lack of modal harmony" - plenty of chromatic music is modal also.
All right Mathis and Gugliel you can both slug me because I was in error about calling these microtonal. I looked up Ligetti's statement and he described his work on these pieces - Lontano, Apparitions and Lux Aeterna - as "micropolyphonic" not microtonal, though the sound is utterly different from chromatic atonalism. On Lux Aeterna he said "I broke with my preceding style of chromatic tone clusters (as in Atmospheres or Requiem). It is a 16-voice micropolyphonic piece with diatonic voice leading of complex canons."
The sound of this actually performed is so far from the clear distinctions of chromaticism in for example Berg or Webern that it something basically different and has clearly audible warping of the 12 written tones, but it is something that happens in the mind of the listener. It would be interesting to compare this to a similarly scored but definitively microtonal piece. I know this will enrage some people but exactly the same thing happens in the 4th movement of the Tchaikovsky 6th: there is a line in the strings which does not exist anywhere on the page, but only in the mind of the listener.
Likewise on Atmospheres - it is scored chromatically but you don't hear it because of the extreme emphasis on color, as well as the creation of perceived overtones and shifts in harmony due to these colors. It is an almost supernatural piece of music.
