Need help with simple looping via Morningstar MC8

I’m having trouble getting the Aeros to record with the Morningstar MC8 MIDI controller, and stop AND erase (any recordings) with one button (one button for record and a 2nd for playback). The MC8 MIDI dictionary doesn’t offer much for this issue. By one button, I mean one to start/stop the record section (e.g., 1st press start to record, 2nd press to stop record) and a 2nd button to start/stop-erase playback (e.g., 1st press start playback, 2nd press stop & erase playback). This is for live looping and I’ve almost got it but at the 2nd button/2nd press, it plays back but wants to overdub during playback. I’m completely lost!

Set the looper to RPO in the settings
Are you in 2X2 or 6X6 ?
For 2X2:
Start & Stop recording :set one switch with CC 41 Value 101 for the track 1 as Press. And another switch CC 41 Value 102 for track 2 as Press. Toggle this commands with CC41 Value 20 (this is to stop the recording) as Release or Press (depend what you like)
If you want to use 1 track only than just make the CC 41 Value 101 as Press and toggle this one with the CC41 value 20

To Stop and Erase:
Make the CC 43 Value 0 (this stop the looper at the end of the loop) as Press
Toggle this with CC 42 Value 0 as Release (this erase the whole song without warning)

@BrennanSingularSound This question has been coming up often. It would be great if SS (or someone else) updated the OpenMidi entries for the above commands so they are more obvious. It’s basically a git repo that you create a pull request on. Anyone can do it.

Thank you, I will give it a try.

Thanks again. I think I’ve got it for the record button press.
For playback, how do I start the playback? It’s not clear to me. In other words, what comes before what’s below to start playback of what I recorded?
“To Stop and Erase:
Make the CC 43 Value 0 (this stop the looper at the end of the loop) as Press
Toggle this with CC 42 Value 0 as Release (this erase the whole song without warning)”

To start the playback when the Aeros is stopped= just press the Start button(top left near the screen)
Are you trying in 2X2 or 6X6 ?
I ask you that because for 6X6 , other midi cc are needed
For 6X6
To start record the track 1= CC 41 Value 100 toggle this one with CC41 Value 20 (to close the loop)
To record another track just below = CC 41 Value 0 toggle this with CC41 Value 20
Every time you gonna press this, you start a recording of the next track below the previous
now if you want to overdub a track press the switch with the CC 41 Value O to select the track you want to overdub and pres the other switch to record an overdub (I mean the switch with CC 41 value 100.
Take care this is not working for 2X2 mode

This is how it works take a look at 1.25 on this video Aeros Loop Studio 3X3 mode ? yes we can with midi controller! (FR/ENG) - YouTube

Thanks for the info. Since I want to use my MIDI controller (MC8) for everything, I’d like to avoid pressing the button on the Aeros (it’s a tough reach on my pedalboard). Is there a substitute MIDI command for that button press? Thanks again!

Is there a substitute MIDI command for that button press?

Which want do you mean?

I don’t know if there is a substitute MIDI command for the Play/Stop All button on the Aeros. What I want to do is fairly straightforward on most loopers. I have two available buttons on my MC8 MIDI controller and I want them to do as follows so when playing a gig I can record a verse guitar rhythm and then after a chorus play back the recording so I can solo over it and erase it when I stop playback. I’d like it to look like this (in 2X2 mode).
Record Button: 1st press starts record, 2nd press stops recording
Play Button: 1st press starts playback of the recording, 2nd press stops and erases the playback.
I thought that would be simple with such a sophisticated looper, but I’m surprised at how challenging this is. Any help is very much appreciated and thank you for hanging in there with me!

No problemo , whe are here to help each others
so:
Record Button: 1st press starts record, 2nd press stops recording
CC 41 Value 101 for the track 1 as Press and Toggle this commands with CC41 Value 20
For the track 2 if needed, do the same with Value 102

1st press starts playback of the recording, 2nd press stops and erases the playback
CC 43 Value 1 (start playback) toggle this with CC 43 value O as press and CC 42 Value 0 as release
How this toggle works (on the Maestro) Keep the switch down until the loop is stopped and release your switch erase the song

Must be something like this

In case of this is not working, just add the CC 42 Value 0 as release on the start
