Hello and welcome around !
So, there are two ways for doing that.
The first is to work in a Loop process (but I don’t recommend this for you if you already have material, this is better if you start a new score).
The idea is to add a Loop to the root and create your score inside the loop.
Here is how to do that :
The second is to use the transport feature, which in the last version is not quite pleasant to use - overhauls are incoming.
To use it you have to add a “Local” device to device explorer, and send messages to the “transport” address.
Here is a short video :
Note that while doing that I just noticed that there is a small bug that prevents execution if you restart at t=0. Starting at t=1 seems to work, I’m going to check why this has broken.
