Need help with maths

Here is my problem :

I want to connect the Y2 outlet of an XYcontrol to the gain of a volume.

The Y2 outlet gives values between 0 and 1 but the gain in of the volume expects input between -80 and +12 (and this is logarithmic me thinks ?)

How to solve this ?

check this:

data /data manipulation / Change Scale (in 0..1) , enter -80 , +12 as min /max
link a fader to this patch and enter -80 , +12 again and choose "log" as scale...?

btw , your song is groovy..

is it different than the mapper value (curve) ?
