ModularSynthComponent issues in 4.19.0

Development Audio
1

Two big bugs I’m running into in 4.19:

  1. ModularSynthComponents don’t seem to play sound when Note On is called, unless they’re explicitly activated. (Auto activate is false by default.)
  2. If you activate a ModularSynthComponent, but change levels before the component is explicitly deactivated or destroyed, bIsReadyForDestroy never gets set to false, and the engine freezes.

Anyone else seeing this? Is there something I’m doing wrong?

For issue 1: I just recently started testing out the new audio system and I don’t know how it was before, but it seems that you have to call Start on the ModularSynthComponent in order for it to pump messages. This is presumably for performance reasons.

Interesting; I wonder if calling Start dodges the crashes
