If that's the case, then it should repeat 3 times total when pressed, regardless of how long you hold the button down. This is working for me with the current version of CCF and MX-980. Changing it to a 1 will cause it to send only once.

I'm using this for a number of codes and macros directly from the MX-980 right now. I also use it in macros from the MSC-400 with success - and I've tested, code by code, to make sure it's doing what it's supposed to in this case. It saves a bit of time on longer macros for devices that work with short IR bursts.
