I had a pretty good Octave setting for my 4 string on my old H9. Good (but not great) tracking etc.
Unfortunately, with the H90, I have yet to find a great setting. The single note tracking on the G string, say, 4th fret, is particularly bad.
I messed around with Poly Octave, good tracking, but just not the right sound. Thanks in advance for any suggestions and settings.
