Hi Teacue,
You ask some good questions, and the answer is, I don't know off hand which algorithms and presets you should be able to recreate, but you are correct that the Dual Shift algorithm seems possible, which means presets based on it should be too. It sounds like you have the manual, so by following those structures you may be able to do some other algorithms as well. As Tom mentioned it's a bit of a dig to find out the preset values, so I won't be able to dig into this immediately. However, I'm going to try to see if we can't spend some time on it at some point, because it is an interesting question, and I'm happy to help if I can.

It sounds like you have the H3000 Manual, and you are right
