if there is a bridged plugin (64bit host with 32bit plugin) with some parameters automated thru meta devices, the audio starts to stutter / slowdown, if the gui is freezed while a popup (like the save dialogue).
steps to reproduce
open test song I PMed to taktik on OSX system
set audio latency to 3ms
open Renoise’s save dialogue. Now wait ~30 seconds
the kick drum starts to stutter until totally freeze
stop slow downing by cancel save dialogue
EDIT: The brigded plugin’s gui can stay closed!
EDIT2: It works with any bridged plugin!
