Quick saving A/B preset can produce recordable crackles

If you save a quick A/B preset while playing / rendering, it can produce _ recordable _ crackles. But saving it should not affect sound at all.

Steps to reproduce:

  • Load a song with quite cpu load, put melda mrecorder in last master slot

  • Put a plugin before mrecorder, for example a limiter which introduces PDC / latency

  • Record the song, quick save a preset of the limiter. If you don’t hear a crackle, try other plugin

  • Stop record. Check the recording, it has the crackle recorded.

In another way said: It seems that PDC is re-set, even the plugin (preset) demands exactly the same PDC! Also the PDC seems to be re-set while storing a preset, not just while reading…
