Although not shown here, the same thing also happens for chords spanning across the pickup measure. This breaks any tabs that use syncopation at the pickup. Please merge them back into a single note.
A similar argument can be made about notes spanning across a key change (that however requires extra effort to make the note refer to the same pitch before and after the modulation, which Hookpad doesn’t at the moment).
Just gonna bump this and say that the same thing happens to notes and chords if there’s a band change. Also if there’s a meter or tempo change then notes display as two and act like one, whereas chords display and act like two
The decision to split items at band changes came from the idea that chords, especially ones with rhythmic playback, should take on the playback instructions of the new band rather than the old one. This also applies to key changes and meter changes since these affect the voicing algorithms for chords. We extended this extended for notes too, although I agree this doesn’t make much sense.
The easiest resolution in my view would be to preserve this behavior for chords but have it not apply to notes.
@HertzDevil you’re absolutely right, the correct behavior across a key change for notes should be to keep the pitch consistent but adjust the scale degrees accordingly.
And on hookpad projects notes that span over a key change with a different tonic will have the same pitch but are displayed incorrectly (e.g. the C after the key change to Db Lydian should display as yellow but instead it displays as yellow-orange stripes)
