Hey there glad you got some assistance and things are working for you, thank you @kingofthejaffacakes for being so helpful, took the words right out of my mouth!
As to your question:
If the Aeros was acting as master clock (not something it can do just yet), the BeatBuddy would stop once the Aeros does, we would likely have to create some behaviors for the BB to either stop immediately or trigger the outro once it gets the MIDI Stop command from Aeros, or something of that nature, more news on that soon so stay tuned.
We would likely not create a stop command to stop the BB when deleting for this very reason. We are also going to be changing how deletion is done as explained here in our Hands Free Mode thread so it would not be an issue as far as starting the BB accidentally when deleting. We plan on doing this change before Master capabilities on the Aeros.
Thank you both for your feedback!
