Drawing the target curve is a nice way of creating it. It's hard to understand the effect of the custom filters without trying them ears on, but it seems you find them helpful. As far as I understand it, it would be far more difficult to do that in REW.

You can export the impulse response to a WAV file. I use the WAV with the LMS plugin BruteFirDrc, which uses the convolution engine BruteFIR, http://www.ludd.luth.se/~torger/brutefir.html. BruteFIR only works in *ix (hum, could that possibly be changed?). It is optimised for Intel, but someone recompiled it for ARM and it worked.

I wonder if there is a better way of solving that problem automatically? Optimise with respect to what? You could of course override anything manually.

I must say I am a bit skeptic about the commercial softwares. Some of them comes highly recommended, but I'm not convinced that those developers know more about filters than others. (They are also quite pricy. Small companies with low sales volumes, I guess.)
