I am wanting to create a send fx control in which as I turn down the dry gain, the send gain is increased and vice versa.
I have started with a stereo output selctor patch but I am finding the gain curve unacceptable for my use as in there is too much overall gain reduction when the selection fader is in the middle of its travel. The only way I have found to correct this is by changing the centre values in the patch but of course this doesn't allow 100% wet or 100% dry signal.
I need a way to set a gain curve so that I can maintain relatively equal gain throught the travel of the dry wet selection fader.
I also had a look at the Fross Cade patch in the addons section but is seems to have not much better luck for me and some weird gain structure overall.
Any suggestions?

I did try that while trying other ideas but not with the output selector patch untill now...
Log does work ok except that most of the fx mix in/dry mix out happens in the last 10-15% of fader travel.
Ideally i would have a 50-50 dry/fx mix when the fader is in the centre position.

Hi, just did a little test with the Cross Fade module sending the same audio through both inputs.

I could not hear any drop or increase in volume as I moved the cross input between 0 and 1. as an extra check, I also tried inverting one input (-X), and it didn't null 100% when cross was at 0.5, but the sound was a barely audible, faint noise.

What about using the Mapper (Curve) after the fader? You could maybe try to create different curves for different types of effects to compensate for the variations in perceived loudness (or the dB on the meters, if you prefer that).

Thanks for the help! thanks to the curves mapper, I managed to come up with something that sounds much smoother through the fade from dry to wet.
