Back on topic.

Because my workflow is tight here, and I use Live on stage I can't afford a new version of Live. (maybe in a year or or two though)

If you can't draw a curved automation with your mouse :

- get LFOTool , you can drag/drop some curvy lines from there as CCs , and copy paste it anywhere. (it's 50$ , it's very light, stable, and stuffs, and it's also a good filter/driver/.. thing)

- install Max for live : it has LFOing preset that will draw some curvy lines too.

as a last hint : don't bother or feed passive agressive folks like our friend.
