Here’s an AUM project that uses 4Pockets Surface Builder to control AUM transport. If you have Surface Builder installed, it will load up and be ready for use.
It has three buttons (in the current version):
(1) Play/Stop (which will toggle between the two), and changes colors and label when running,
(2) Prev bar – Jumps to the previous bar
(3) Next bar – jumps to the next bar
