While I'm not thrilled about some of the bugs in Analog Factory 2.5, I discovered something that I have never noticed before. Not sure if it's in version 2.0. If you go to a preset you like, and click on EDIT, you can change things like MONO/UNISON/POLY, POLYPHONY SIZE, and SEQUENCER STEP SIZE (affects SEQUENCE-type of presets). I changed preset AMBIENT2 from POLY to UNISON and had a significant effect on the sound. You may want to check it out. I didn't see this in the version 2.0 instruction manual.
