I am taking my first stab at Python and am wondering if someone can help. I generally understand the "if, then" style of programming, but obviously there is always more to it than that. I have taken Myralfur's code (seen below) and am trying to make a fairly basic change (or so I think). Slider 9 controls master volume on all 4 scenes. I would like for it to continue this functionality on Channel 1 (Scene 1) and Channel 16 (Scene 3) but bypass (transmit incoming messages) for channel 3 and channel 4.
Can anyone tell me what I will need to change in the python script to pull this off?
Thank you, Neil
P.S. I am looking very forward to the M4L version. Any guestimated ETA?
