It's more stable than 2.11.6.
It has some bugs here and there but nothing too serious on my MPC One. I don't use MIDI learn.
I've made at least 20 complete beats mixed and mastered in standalone in the newest update. People act like it's totally broken but the main functions work fine. It's getting the job done.
Most of the issues are related to controller mode, and it seems more so with the Live and X than the One.
They keep adding features but abandon old broken features.
It would be nice if they fix the AIR efx that have been broken for over 5 years in the software. Funny thing is all those efx got a fancy new GUI but they still don't work right in the MPC software. You have to click a single pixel to open the drop down menus within the efx. Do you know how hard it is to click a single pixel with your mouse? Workflow killer.
