Yes, it did. In v1.x, the ENVelopes didn't use the full modulation that they should, so if for example you'd set the ENV to full on VCF mod, it would sound as if it was only set to 50% on a standard 3P. The v2.x properly controls the full range, and can properly do the same as a standard 3P, plus all those nice things extra!
