What about this Custom Action (see attachment).
(assign the Custom Action to a selfchoosen keyshortcut for fast workflow).
This is how it works:
- Just point your mouse onto an Item you wanna solo.
- type the selfchoosen shortcut.
- The pointed item will now be solo-ed and be played from it's start.
- if you have loop points linked to Time Selection and you have Transport > Repeat ON,
the solo-ed item will be played looped (can be handy for rehearsel of the solo-ed item)
But maybe this Custom Action goes "abit too far " for you.
Then you could maybe just use this custom Action:
Item: select item under mouse cursor
Item properties: toggle solo
Item navigation: move cursor to start of items
Transport: Play
In any case, both Custom Actions provide even faster and more convenient workflow that in Logic i think
