@Butahuruf Last point first.
You can mute loops like this..... my_mod_mute.pd
There is a lot of other rubbish in there, but it should simply mute loops......... but it should also still mute them when the play buttons are used.
Same principal....... put it in the folder and then the patch.
All day studying the logic part of the patch today.
It is built not to start recording the second loop until a whole first loop has played once, because it needs time to set and get the tempo and do a few other things and by then it has missed the start of that first repeat.
I am going to have to sleep on how to change that.
Are you using this with the arduino hardware?
Is it important that the second loop starts recording immediately as the first stops?
