I hooked up the AR2 to the Digitakt tonight to make use of AR’s song mode capability. The pads on the AR2 can also be used to mute the corresponding DT buttons 1-8 but after that things get weird. Only pad 10 mutes button 14. Pads 9, 11 and 12 don’t mute anything on the Digitakt. This isn’t going to cause me any problems but it does seem a bit strange.
