I've usually got it dialed in to 64 (maybe 32). I guess I could do 96, too (but honestly haven't tried that yet). Would I use 128? Maybe. Or I would find that what you are saying is true, Joey, and it could be too much. It would be nice to at least have that option, though. I don't understand why it has a limit of 99; 128 is a much more logical cutoff point. There is just something inherently wrong with it stopping at 99. I don't understand the limitation at 99.
The results I get from PatMut are usually pretty cool, but rarely what I would use in the final version; the notes always need some tweaking here and there. And I think that's the intention; and I like making the adjustments. It seems like tweaking 128 steps instead of 64 or 32 could help the workflow (I would at least like the option).
