Switch radio channels on Streaming Player from KNX push buttons

Example: Switch radio channels on Streaming Player from KNX push buttons, through Logic Machine 2

Task

Assume there are two KNX push-buttons 1/1/1 and 1/1/2. And there are 4 radio channels mapped on Streaming Player to group addresses 9/2/3, 9/2/4, 9/2/5, 9/2/6. We want to make so that when pushing on 1/1/1 the system jumps to the next radio channel, when pushing on 1/1/2 – to the previous one.
