3.6 Mix Assignments
The SQ sends and receives absolute On or Off assign messages. It will also
toggle the assign state when either an increment or decrement message is
received.
MSB and LSB represent a parameter number showing where the signal is
being sent from and where it is being sent to.

MSB/LSB parameter numbers are shown in the reference tables section.
The last byte of the full message then represents assignment on or off.
Assign On
MSB LSB Assign On
B N 63 MB B N 62 LB B N 06 00 B N 26 01
Assign Off
MSB LSB Assign Off
B N 63 MB B N 62 LB B N 06 00 B N 26 00
Both where:
N
= MIDI Channel ,
MB/LB
= MSB/LSB Parameter number
When either a data increment or decrement message is received, the SQ will
toggle between assign states, in the same way as holding the Assign key and
pressing a Sel key on the SQ does.
Assign Toggle (increment)
MSB LSB

B N 63 MB B N 62 LB B N 60 00
