Fader to Matrix Audio dB

[gurulogic]

I am making a Matrix based audio mix interface with faders etc > set array > Matrix Audio and am stumped on how to have the fader that I am setting the matrix cell value with show a precise dB reduction value in relation to the actual Matrix Audio output gain.
Any suggestions?

maybe didn't get all the problem, but istn't it what ' coefficien to db' is supposed to give (/math modules)?

Yes I was trying (with dB to Coefficient) but not finding a solution that works.

I think the Matrix cell must have already an integrated value scale? I can get close with a change scale module with min in -60 and max in 0 (output 0-1)
In this case as far as -12dB reduction seems accurate but the further I go the more drift. Have tried various min values in the change scale but to get for example -30 locked I lose my calibration for other values.

Sorted for now. There is probably an easier solution but I plotted the required curve shape using the points curve module and am close enough for my needs.
