Can I program a macro to change a parameter based on the current status?

Can you give a little more context about what you're trying to achieve? For a simple on/off, load the channels at the desired levels into a sub, and set the dwell time as hold. That makes the bump button the switch. It's fairly simple to make a macro that fires the bump button if it has to be on a magic sheet.

Ahhh bump. That's exactly the solution I needed. Thank you!
