@whale-av David, it works! Thank you!
I try to make the dedicated mute buttons, but for now it is ok.
2 things. I connect the mute buttons to the keyboard. it mutes as long as the key is down.
Can you change it toggle?
and can you release all mute buttons if the "all play" button is clicked?
I also try to understand the audio > recloopsaveundo to change the behavior of overdub (write_other_loop) ... this is most reasonless of this looper. Why should you wait to write another loop on the existing table?
I would like to start the overdub immediately without waiting for the end of the loop cycle. My PD knowledge is still very beginning to change this.
