Created a page with 8 rows, each row is a channel representing an audio loop.
Each channel can be muted with a toggle button
A lower section controls the playback with three buttons you can play, pause, stop and a loop button which can be toggled on and off, as well as a timer to show the current time playing.
A red line shows the location of the playback and you can drag it back and forth to move through the audio.
