Now I've got several questions, I guess non of them is mentioned in the 
outdated manual, but I might be wrong.

    * IEC 268-10 and dB full-scale. IIUC a headroom of 9 dB is safe for
      dB full-scale sine wave, because root mean square seldom is over 3
      dB to 6 dB above the displayed level, hence there still would be a
      headroom of 3 dB and even for full-scale square wave it would be
      at 0 dB. Did I understand this correct? Does Qtractor's meters
      refer to dB full-scale sine wave? I guess when using 96 KHz float
      32-bit under leveling doesn't cause audible loss for the sound
      quality. Keeping the maximal level lower than -9 dBfs e.g. between
      -20 and -50 dBfs for audio tracks is without audible loss for the
      sound quality, assumed there's no noise. To gain the level for the
      mastering won't have any unwanted effects. Is this a misacception?
    * Panning for mono tracks, resp. balance for stereo tracks. The
      "approximated equal-power effect" should cause nearly no
      difference for the loudness of signals that are entirely to the
      left or right, while other signals are in the centre, when
      listening to a stereo mixing on mono. The relation of the signals
      nearly should be kept. Is this right?
    * How can "tracks that share the same output bus be viewed as a
      group"? Don't they always share the same bus?
    * How can I add insert IOs to an audio track, excepted of an LADSPA
      that is inserted and that would "emulate" this?

Btw. I'm still at version 0.4.4.1496, but I'll upgrade soon.

Cheers,
Ralf
