I am curious about this as well so went on a rampage searching for an answer (hard to google the new sonar stuff but I have the PDF on my laptop now).
Anyway... I'm not at my DAW and will try this when I do but there is Piano Roll View "Views" menu entry called "Fit MIDI Content" that seems to imply that it will cram all the notes into view...
"Fit MIDI Content. Fit all displayed MIDI content into the visible area of the Piano Roll view."
or maybe, again in the PRV "Views" menu "Grid Resolution"...
"Grid resolution. Use the submenu to specify the vertical grid resolution:"
I will of course check those out later but perhaps you needed an immediate answer so thought I'd toss out
those suggestions.
If we are stuck with that note height as the minimum that will be rather problematic. I do appreciate the larger notes for sure BUT not at the exclusion of the option of smaller note heights. If we are indeed stuck with the larger notes then a feature request will be forthcoming.
Hope you have been well, Keni. Glad to see you working. Cheers.
Edit: BTW... those entries are on page 2025 of the PDF Reference Guide and the PRV details/instructions start on 2024. THere are obviously other entries throughout the mammoth manual but that seems to be the bulk explanation.
