With the MUX previous address command the MUX pointer can be moved up in the MUX table (see page 49):

With the MUX set RM and MUX reset RM command the sequencer can be configured for ratiometric mode or PWM

mode:

MUX fade is used to set the sequencer in ratiometric mode and configure the faders which are connected to this

sequencer with one single command - no additional MUX tables are required:

address defined by MUX set end address; load the MUX with the content

of this memory address
