Audio delay when automating EQ

[Przemek]

It does mute audio without automation as well - at least here.

From your descriptions, it sound like the problem your having *may* be due to a misunderstanding of how the Focusrite d2 Plug-In handles bypass. There are three "states" of this control in the Plug-In:
- The EQ band is disabled (the GUI shows "black" on the band icon type).
- The EQ band is inactive (the GUI shows grey on the band icon type)
- The EQ band is active (the GUI shows white on the band icon type).
When you make a band inactive, you shouldn't get any interruption in audio playback. But you <will> get the problem you describe if you switch between an active state and the "disabled" state. When the band is disabled, it's actually switching the DSP code for that band off so that it frees up the DSP to be used by other Focusrite d2s of the same type on a DSP chip. This takes longer to accomplish, and is not necessary… you should instead use the inactive mode. It's easy to make this mistake, and have the problem happen… and this behavior is listed in the manual for the d2. The three different states of the control also show up in your automation playlists for the control, so make sure if you're manually editing the state of the bypass control of a d2 PI that you're actually going between active (in) and inactive (out), not "active" and "disabled." Hope this helps…

I've encountered this problem in several different sessions - when I automate the bypass on any band of Focusrite EQ the audio playing at the automation point mutes out for a second and then returns. This last time it happened when only one track of dialog was playing back, and the EQ bypass automation was on another track altogether. When I moved the automation point to different places in the track the problem followed, muting any audio that was playing. I'm running Ptools 24 Mixplus on a G3 333mhz with an Apogee AD8000, Digi 888/24, SMPTE slave driver and Magma expansion chassis. Any ideas on what's gong on?

Thanks for the help Dave!

Stand corrected if this is it

PS I use it not very often...
