Description

Issue type

General playback bug

Description with steps to reproduce
  1. Playback attached score
  2. Note that first cresc. plays, second doesn't.

Appears to be related to the fact that the first ff is all voices, whereas the last is voice 1 only.

FWIW I just copied and pasted the passage originally, then replaced the final ff to get it working.

Why are hairpins created in Voice 1 but dynamics in all voices?

Expected behaviour: hairpins should always play, the way humans would read them, regardless of what dynamic markings exist in the score. If dynamic markings exist that would logically apply to the same notes, they should be honoured.

It's not sound library specific.
