I see Midiboy covered track names. Great. Sorry for getting back late on your question, MisterE.
As for the endless encoders, they are not dependent on physical position as opposed to non motorized faders which are. So in the case where your channels shift by 1, 2, banks of 8 channels, etc. the position of that fader, let's say at 80% will sit there at 80% (physical position and relative value).
The fader will have to move (with no value change during movement) to eventually pass and latch, to regain the software value of that new channel.
That is unless the channels were identical in value.
Such pots or faders either jump, or you slide the fader until the fader re engages with the software's position. This latch engagement is the standard scenario for soft takeover. The downside of this is if you're further into a mix sensitive song, can you afford latch re positions? They do change because when latching, the user tends to move the position a little extra. Almost always. Its certainly better than having it force a jump which really won't happen on the mixer channels. Jump can or will happen in certain parameter adjustment situations. Just saying.
If you check your Arturia Keylab mk3 manual, it allows you to select latch or not.
On the contrary, with an endless encoder, or motorized fader, there is no such shift because the encoder instantly reads from any change in value. An increase of 3% will result in an increase of 3% with the software. Sent or received. Changes are seamless and always updated.
I'm not a fan of itsy bitsy 30mm to 50mm non motorized faders having to latch, and re-engage software values when they switch channel positions. Some won't care, and that may be fine for their needs. Features often come at a cost, but its good knowing what one needs ahead if at all possible.
While endless encoders don't rely on position, a subtle advantage is when they have LED's positioned around them. They won't be as visible or tactile as motorized faders, but they will display position. The choice would be up to the user and how they work. Perhaps more towards synths, than mixing for example.
Remember, channel (or bank) reposition throws all of those non motorized fader positions (and knobs with a limit) out the window, once changed. In short, its a hassle. Not so with endless encoders or motorized faders. Thats the big advantage to take away, here.
The most visible advantage are either endless encoders with LED's, or motorized faders. Motorized faders win on the tactile mixer front.
Hope that explains some of the topic.
Consider, on a NI S49, 61, or 88 mk2 or Mk3, while the encoders dont have LED's around each knob, they do have a big beautiful screen indicating each channel level, solo and mute status, and potentially track names for all 8 active channels.
Like Midiboy, I use a Faderport 8 for the mix, sends, bus, and tactile advantage.
