I’ve noticed that it’s still available in preferences for new tracks but it’s gone form the options when right-clicking on a channel panner. The only two options now are “Stereo Combined Panner” and “Stereo Balance Panner”.
I realize that the “Combined Panner” can do everything that the “Dual Panner” could do but it’s a slightly different workflow. I preferred the “Dual Panner”.
The Dual Panner seems to still be around if I import a 5.5 session (and it’s still in the preferences) so I’m curious why it’s not an option for new tracks anymore.
