I have my default template set in such a way that my input is in the left zone of MixConsole and output in the right.
Each new added track/channel gets created in the middle zone.
However, also FX channels get created there, whereas I’d prefer them to be pinned in the right zone, next to output.
Is there a setting somewhere to make this default behavior?
Good question. This annoys me also.
Yeah, I hoped maybe Track Presets would offer a solution here, but there’s no presets for FX Tracks 
To the best of my knowledge, there is no mechanism that allows a newly created channel to appear in either the left or right zone of a Mix Console either automatically or by use of Key Commands or PLE presets.
One workaround could be to add spare FX (or Group) channels to your template. These spare busses can be hidden in your template and later shown if/when needed.
Yeah, that’s what I ended up doing. Thanks.
Maybe a feature request is needed.
Coming from Studio One this is really one of the small things I miss. FX and Group tracks are by default nested on the right side which makes it easier to navigate - and this is an optional setting so not everyone is forced to work this way.
Really? Last time I used S1 (around 6.x) you could have the FX Channels placed to the right of all other channels, but NOT next to the Master in a separate, right zone (like Cubase can, but doesn’t do as default).
Has this changed?
No the Master out is always the far rightmost channel except the “listen bus”.
It simply groups tracks as “tracks” > “effects” > “busses” > “master out”
There is no “always visible” nest.
Correct. In MR API there is a function named getMixerChannelZone which returns the left-mid-right zone of a channel as a number (-1,0,1). Probably a setMixerChannelZone could be implemented too, perhaps a good FR.
