3The trim function is active. The trimming factor is a
combination of both Direct and Proportional modes;
the proportions of each are defined by parameter 40.54
Set 1 trim mix.

0.000 / real32When parameter 40.51 Set 1 trim mode is set to
Combined, defines the effect of direct and proportional
trim sources in the final trimming factor.
0.000 = 100% proportional
0.500 = 50% proportional, 50% direct
1.000 = 100% direct
Set 1 trim mix40.54

1.000 / real32Defines a multiplier for the trimming factor. This value
is multiplied by the result of parameter 40.51 Set 1 trim
mode.
Consequently, the result of the multiplication is used
to multiply the result of parameter 40.56 Set 1 trim
source.
