Protools 11HD - need to downmix / downconvert a Quad track (L/R/Ls/Rs) to Stereo L/R by discarding or nulling Ls/Rs.

There doesn't seem to be an intuitive way of doing this. No downmixer exists in stock PT for Quad to Stereo downmixing.

  • I must be missing something obvious here... can you not simply mute the unwanted channels & export the rest to stereo? – Tetsujin Aug 13 '18 at 11:41
  • Nope. It's a protools thing – Mark Aug 13 '18 at 16:15
  • There seems to be a lot of simple stuff it can't do... jus' saying' ;) – Tetsujin Aug 13 '18 at 16:18
  • I'm confused also, and I'm a long-time Pro Tools user. Did you import the audio as a single multichannel track? If so, that's your mistake. Import the audio as four separate tracks. Then you can mix the tracks however you need to. – Todd Wilcox Aug 16 '18 at 15:52
  • @ToddWilcox This is actually part of a wider initiative to work around a limitation in protools. I am mastering a classical album that has a number of different sections that require de-noising with different profiles. I am attempting to use panning to overcome a limitation in the automation where the "volume" automation fades do not accurately represent the actual dB reduction in the fade. Half-way down the fade should be a 6dB reduction (or 3dB depending...) unfortunately it's not, it's about 19dB. This causes a massive dip at the centre of the crossfade. – Mark Aug 20 '18 at 7:13
