Oh and make sure your inputs are defined at the preset level for incoming only from APC40-MK2 and output for only BMT 1. I would do this at the preset level and then all faders under that preset.
I also created a file below with the preset inputs and output set and a different methodology (scaling) to make the fader smoother through the whole range.
See attached.
New rules are
qq=pp*109
qq=qq/128
the output is set to qq.
