Setting grouped button states without extra MIDI send

Question

I'm using button groups to get 'radio button' behaviour, with each button sending the same CC message but with a unique value. The receiving device stores the latest CC value as part of a patch, and each patch can have a different value. When a saved patch is selected, the device sends the stored CC value back to MD to restore the selected state of the buttons in the group.

This works fine, but it appears that for every CC message received by MD, it sends another one back out. I'm guessing that it is because as one button is selected, another is turned off, and that change if transmitted. This is a snippet of the log:

Message Out: Cmd=176|Ch=01|Data1=020|Data2=000 | Length=3: B0 14 00
Message In: Cmd=176|Ch=01|Data1=020|Data2=001 | Length=3: B0 14 01
Message Out: Cmd=176|Ch=01|Data1=020|Data2=000 | Length=3: B0 14 00
Message In: Cmd=176|Ch=01|Data1=020|Data2=002 | Length=3: B0 14 02

Sending the values 1 & 2 select the different buttons, and there are 0 (off) messages inbetween.

I would like to stop the transmission of these when the change was caused by MD receiving a MIDI message. Obviously I need to be able to press the button and have the message sent normally.

Is there a way to do this?

Thanks!

There are two settings that might be relevant. One is Bounce Back for Buttons Groups in MIDI Designer.  The other is Buttons Are Send On Only. These are both configured in the Supercontrol Options for the knob that groups the radio buttons...

Thanks for the answer. I experimented with the suggested solutions when you first posted them but without success. I've gone quiet on it for several weeks because I've had to concentrate on developing the device firmware. Hoping to get back to it over the next few weeks.
