Please improve the rotary encoder kinetics. At the moment they are jumpy, either responding to slow or to fast. They need to be much more linear.
Right now if you want to change link/inverse pan/inverse rear/ F-/R inverse status, you have to do it in the pan window with the mouse. It would great to have to assigned to some of the sel/in buttons or even some extra encoders so you can access them from the S3 as well
Make it possible to flip parameters for example the gain of en eq-band by pressing shift and option/alt and touching the correspondent knob or fader on the control surface. Just like if you shift option-click control points in the EQ graph.
Please add an option to disassociate the computer keyboard modifier keys from Eucon control surfaces. I am often recording/editing on a Pro Tools session at the same time the engineer is operating the control surface. If I am using the OPTION key and he touches a fader at the same time, it jumps to 0dB.
When touching a fader during playback, the according auto mode button in the right side softkey section of that channel starts to blink. It would be great if this would also work when playback is stopped. It would also be great if this would work for the trim button as well. Of course this is no subsitute for a proper automation mode indicator on the lcds, but it would already be helpful.
It's great to have the talkback functionality on a Pro Tools S3. It would be even better, when it would be possible to mute talkback automatically when Pro Tools is recording and open it when in play or stopped.
in a session with considerable amount of busses it's virtually impossible to assign busses on sends or I/O's in a reasonably convenient matter. This could be hugely improved by spilling them across the lcds, or first browsing 'subgroups' (e.g. bus 1-20, bus 21-22, ...) before browsing the actual busses. Or maybe a combination, just like when inserting plug-ins (which works very nicely)
When soloing one or more channel, all other channel mute buttons lit up. This is not the appropriate behaviour. Their state should stay the same, just like in the edit- and mix windows. There is no reason why those mute buttons lit up, as it is already indicated that tracks are soloed, by their solo buttons being lit, as well as by the blinking clear solo button.
If you want to change the auto mode of a channel twice in a row, you have to double tap instead of single tap the corresponding sel button twice instead of once 95% of the time. In combination with the lack of proper visual feedback on the s3 this is very annoying.
