Immediately after posting, I realized the stated use case was sort of silly. I had got wrapped around the axel recreating an eventide video with the 1.3.5.7 pattern trying to dial it in ‘knob mode’ instead of setting it up in ‘note grid’ – which I have been using exclusively.
However, trying to at least redeem the question, I noted that the iPhone version didn’t seem to have ‘note grid’ – in which case the ’note grid’ isn’t available, and the original feature request remains. Sadly, I don’t use the iPhone version so can’t be sure if my claims, nor remain dependent on the outcome. Sorry folks! I would like iOS background support so H9 control doesn’t reset every time I switch to another app – but that’s another thread…
