12.1.2 still has dynamics bug / audio glitch
As detailed for previous versions:
Relates to using submixes / multichannel sequences & dynamics/de-esser/compressors fed from tracks without audio.
Audio glitches/noise appear mainly on A3&4 and A7&8 on an 8 channel sequence. They are present on an export from PP but not apparent on an export queued via AME
Reliably recreated in fresh 2018.1.2 project -
Create sequence from DNX SQ preset - change last track to be mono submix
Add Color matt about 2:00 so seq will play silent tracks
Add small amount of bars & tone at top of seq
Use send bus to send track 1 to submix 1 (leave send volume at - infinity)
Add a de-esser plug-in to the submix bus
Play sequence and observe feedback on Right output (you may have to play some of the tone first)
The team is currently looking at this bug.
Still broken in 13.1.3
Still broken in 13.0
Also occurs with Essential Sound in multichannel sequence.
Haven't figured out a repeatable case yet
