record midi in loop overwrites everything. How to merge notes?

[damasio]

I can't figure out how to manage midi note recordings in loop.
Midi notes are overwritten while recording in loop mode. I want to merge midi notes in loop recording in stead. How can i achieve that?
The midi merge button in transport is greyed out, and i can't select it for unknown reasons.

thanks

Ive never used loop recording for midi (just audio to work out parts). I simply do my main midi part to satisfaction and then merge additional parts as needed to satisfaction, then eventually its all there for the final edit before transferring to audio.Thats my workflow. FWIW

You need to disable Loop Record mode for midi merge to work but you can still record using midi merge while looping. Here is a quick video I found explaining how:
