Song Position Control / Scrub The Arrangement

We have been asked this a few times via email (and on the forum),
Thought I would start a thread for it as it’s now possible with Reactions v2.
So the question is, how can I scrub through the arrangement view / control the arrangement playhead with a knob style control.
You can use ‘song > set current song time’ Then select ‘get value from ranges’ for controlling it with a range style control i.e. a knob.

Import and and use the attached script: scrub_the_arrangement_playhead.json (contains 1 reaction).
In the reaction, make sure to select the correct listener i.e. knob 1
Then in the action, for ‘current input value’, make sure you select the listener’s latest velocity value (i.e. knob 1’s latest velocity value).
If you want to extend how far/ the range of the playhead, increase the ‘output max’ number.
