Hi,
press CMD-8 to open the environment window. Select "new - arpeggiator"
Now think how you want to trigger the arpeggiator. Do you want to trigger it with a MIDI Region? Or do you want to trigger it with live MIDI input (from a keyboard or so)?
Maybe you also have to select "new - physical input"
You can pull cables inside the environment window. pull a cable from the source trck or source input to the arpeggiator. Then pull another one from the arpeggiator to the drum track you want to trigger.
Now select the arpeggiator and set up the speed (1/8, 1/16 - what you want). Look in the manual for "arpeggiator".
Now the master-hint: The arpeggiator only functions when logic is
running. So when stop or pause is pressed, no arpeggio 😉 So, start your song, only press 1 key and voila: there are the manymany drumdrumdrum bangbangs.
Have Fun, and good luck with the setup - i tried some time to get this right.
