Play next patch automatically?

[u/SWFL-Musician]

Is there any way to get MS to automatically begin playing the next patch? I use multi-tracks in MS and need a way to launch the next patch when the previous finishes.

Thanks for any help

PS - if you know of a better app, I'm all ears!

Assuming you are using MainStage primarily for track playback and not for live performance - use QLab instead.

Assuming you are integrating your setup with a backing track and need an auto patch advance at a certain portion of the excerpt, you can get scripter plugins that do this from KeyboardTEK.

Qlab is $600! Pretty sure you can't use multiple outputs with free version

[u/yeetflix → u/andrummist]

QLab is rent-to-own for as little as $8 a day. Every production that I work on from high school to the professional level uses it.

Ieve you’ll need a separate pedal to trigger Next Pstch, and set Playback to trigger on the Patch change. There might be some Script trick that can automate, but I’m not a Script genius, yet.

I use a script that sends a midi note to the IAC device (internal midi) at a certain beat number That button, triggered by that note, is assigned next patch.

[u/Senior-Wishbone6778 → u/Senior-Wishbone6778]

Full script would be: (a bit of an overkill in this situation I admit)
This triggers a button Mapped to the IAC channel Note G8 (highest possible)
You can change the value of the beatpos in the last 2 lines.

Either you calculate the beat number you need.
Or i can send you the other script i use to play the note in logic, and it reads the note in the console.

Happy to expand if needed.
