This is 14 Bit CC MIDI Channel 7 CC 23
B= CC
6 = is MIDI Channel 7 (MIDI channel 1 is 0)
17 = CC 23 (Hex 17=Decimal 23)
The third number it the MSB Value
The B6 37 xx is the LSB (always 0x20 higher than the MSB) so ignore that except for the fact knowing that it is a 14 bit CC. The rules manipulate the last numbers to come up with the desired 7 bit value.
You should be able to duplicate the existing translator the change the incoming trigger and out outgoing 7 bit CC and then MIDI learn the new knob.
