Avoid resending MIDI in "On Midi" script?

[drmq]

I've got a switch of 4 rows:

with a script to receive custom midi:

and a script to send custom midi:


However when I set "x" in the former, the later gets called again creating a loop. Is there a way to set "x" without activating the send midi script?

Thanks in advance!

Perhaps create a new expression and "ditch" x?
