I found myself adding the loop in the pick a loop dialog. But I can't find the LOOP I added myself in the LOOP in multipicker.

So why would I want to find my own LOOP in multipicker?
Notice that there is a "generate" button on the LOOP in multipicker. This is very convenient. In the past, I would have had to click Build All to make my added LOOP build, because there was no option to create a LOOP separately.

My question is, how do I see the LOOP I added in multipicker?

You should not have to Rebuild to see new loops added in the MultiPicker and it should show the other loop option like tempo, number of beats, transpose etc...

Yes, I was stupid. I forgot to rebuild.
I will now click Rebuild. These loops appear in multipicker.
Thank you for reminding me.

I forgot, you forgot others will forget...there needs to be a better way, we should not now have to Rebuild in the Styles Tab each time we add a new loop, it takes too long now doing a Rebuild !!!!
