Here is a video where I show my mapping for the apc 20. Each row of buttons, from top to bottom go: slot size /2, slot size x2, slot size reset and slot phase sync. Those same 4 buttons give me led feedback in red showing me each sample broken up into 4 quarters. The fifth button lets me know if a sample is loaded and playing.( green and yellow ). The row of activator buttons work as temporary mutes.
