Can you share some insight as to how the "ported" algorithms on the H9 compare to the original ones?
Sorry – it's a big topic. The main issues are:
1) You have to control everything with fewer knobs.
2) All controls have to be "smoothed", meaning no zipper-noise issues.
Trust me – a lot of work. Each new algorithm we produce needs several months of skilled work beyond the "basic" dsp stuff.
Did I mention that this stuff is not easy ?
If you are seriously interested, get an H9000, or a used H8000 or Orville, and give it a try.
