Is BUS AUTOMATION supposed to be latency compensated in CbB

Recommended Posts

Hey there all :

on a not to heavy session, in order for a reverb return CUT automation (using volume),  to be landing on the "1" (bar 26 in my exemple below) I need to offset the automation points quite a bit

Is this normal behaviour/something to be expected in CbD

further enquiring this, bus automation are not latency compensated.

On an empty project with a couple of plugins, timing of bus automations is correct

When projects get advanced and plugin count gets higher, bus automations are being offset/delayed

This makes it impossible to create cool fxs/cuts that are tight with the piece & can be pretty detrimental in a context of modern sounding music making

does anybody know why? is this a limitation? as this was not the case in 8.5 btw on very heavier sessions

Hm, weird, I have not had problems with the timing of bus automation, I have been automating many bus volume levels and bus effect parameters during the years. Also to create cool effects & cuts. :)

Are there any specific plugins that cause issues?

I don't have this problem either, but in the event you are automating effect sends, you aren't going to be able to cut off the tail of a reverb by silencing the send.  You have to automate the reverb bus volume if you want to do that.

allright so - I'm having a ton of problems it seems now that my session has gotten near completion. mind you this is a massive session with a lot of processing going on (as it should for large mixes), a ton of automation, and now even simple TRACK volume automation are not accurate anymore. I was suspecting buffering issues this morning before closing the project and going to bed -

today, I purchased a new tool : True Dynamics by Kazrog for bus compression (unbeliebable processor btw)

I load the plugin

instant "buzzing" and distortion on my heavy session.

I try it on an empty session, and one with not too much going on, no buzzing no distortion.

I try it in a heavy session in ableton Live, no buzzing no distortion.

I decide to write to the developper, what he replies is in the image below

This makes a whole lot of sense and completly correlates with all the automation issues I'm having, the further and heavier a project gets.

same issues wether track automation, bus volume (or other) automation... this has to do with "under-the-hood" things with CbB

Have not looked into this, but if automation were not compensated for latency, iI would expected it to be happening too early, not late/delayed, relative to the audio. But it might depend where the automation is happening relative to where the plugin is operating. If I'm understanding correctly, you're automating volume on a reverb bus, and there is a delay-inducing plugin(s) is on track that sends to that bus. Is that right? Is the reverb also a convolution type, or otherwise inducing delay of its own?

What version of CbB are you using? I've actually stayed at 2019.09 so far, as the later releases introduced a lot of buffer changes that seemed to caused a lot of stir. Maybe they're solved ny now, but I'm in an important phase and can't have disturbances. :)

Sorry if this is obvious, but as you mention "buzzing" and distortion in a heavy project: have you tried different (= larger) ASIO buffer sizes? In another thread recently, someone was complaining about latency but used plugins that absolutely required big buffers to work properly, like Output's Kontakt stuff etc.

Edit: Thanks for the tip about True Dynamics by Kazrog, will check it out. Seems they adore it at Gearslutz. :)

...but I'm not sure I agree with Shane McFee's analysis that Cakewalk's popularity is dwindling... judged by this forum at least, there seems to be a lot of new users around, which is great! :D
