It could be thicker, perhaps it's not as visible on non-retina screens (Apple is clearly moving to retina, and we optimized for this). I'll have a look into this. Also it does run across all tracks in play mode, but in stop mode you want to see which lane it's on because that will be the top-left target e.g. for paste commands. (An earlier version should the playhead across all tracks as you suggest, but we decided against this because it was hard to tell which track was selected.)
There's going to be more, not less, animations. Sorry -- we like animations But I can imagine giving an option to switch them off in the Preferences -- that would make a lot of sense.
Good idea, we've actually been discussing this. There will be movement on this front relatively soon I think.
It would be more standard to put it at the top, but basically you have the right idea.
Totally agree -- it will come, but I don't want to make specific promises on time.
If I understand what you mean, you want to see the current value of a rotary or fader displayed as text, and you want to be able to edit it. Assuming that's what you mean, I think that makes sense -- @RobinFisher has been asking for the same thing, but we had to prioritize other things for this release.
We use right-click (two finger press) for this purpose. We say this unapologetically: ALK is optimized for use with trackpad... on trackpads, to finger press (or tap) is very easy gesture.
Totally agree --- and we're going to add a Master Track too, soon. With proper metering for clipping.
ALK allows tempo to be automated (use Scripted Command Regions with Transport->Tempo destination) e.g. between songs, but tempo changes during composition are not currently supported due to difficulty with recorded audio. You basically need to realtime warping, which e.g. is not possible in Ableton.
We keep getting requests for this, so we will consider it carefully. I can't make any promises about time thought; it's a really tricky protocol to get exactly right, requiring a lot of UI stuff to deal with all the issues surrounding the protocol (mainly drifting, but this is a real nightmare). I have yet to hear of musician who's used Beat Clock without some serious headache which was so bad that after a while they just ditched it...
In 2018 best way to do this is Ableton Link, and we will definitely support that -- soon.
Receiving clock is something we'd consider, sending external clock is again can of worms due to jitter.... this is not a priority for us currently.
Hope this helps, and thanks very much for your input, @gigging!
