Any ideas why automation sounds different when bounced down? (Remix FX)

[zestyOrange]

Hi. I have Logic's "Remix FX" plugin on a track & I'm having some issues when I render it (you can hear the audio below: the correct version followed by the incorrect version).

• 90% of the time I play the track the bass effect sounds crisp and as I intended it to.
• The other 10% of the time during playback it sounds blurred at the end
• 100% of the time when I bounce it down or export the track, the bass sounds blurred.

I don't have Low Latency mode on. I have tried playing around with the automation start/stop points (you can see what I'm automating below - the repeater rate and on/off are the things controlling the sound here). As far as I can tell the difference has nothing to do with the bass layer being selected (or unselected). 

I eventually did a workaround by recording the audio in a 3rd part app via a capture/loopback plugin and then bringing the correct sound back into Logic as audio but it was a pain and I'll have to repeat the process if I change anything.

Any ideas what might be causing it to misbehave?

EDIT: When writing this post I hit the wrong key-combo and posted too soon, like a muppet! - apologies if you saw the original post which contained next to no info

Are you bouncing in 'offline' mode - try realtime if not. Automation sometimes messes up in offline.

Yes, I agree with this.  At least with a real-time bounce you can hear what is going at the end.   You could try adding the "include audio tail" option when doing the real-time bounce which will extend the time to capture audio at the end of the file.  But I would not expect that to make a difference unless you have some reverb or sound-effect that needs a fade out time past the measure Logic currently has set for the end of the bounce.

So that worked? Let's mark that answer as the solution if it worked for you.

Thanks, @Jellignite and @zplane - an option I didn't even notice existed.

@David Nahmani It did indeed. I marked it Solved immediately, before replying - if it's not showing as such your end let me know and I'll try to resolve it.

No worry I see it now thank you! 🙂

Offline bounce has had a problem with automation (and things like delay repeats sometimes) for as long as it has been implemented if I remember correctly - that's decades, possibly. No idea why it hasn't ever been fixed - it's such a howler. Fairly sure it's the reason Avid resisted implementing it in Pro Tools for so long.

It's a net time waster for full mixes - you need to listen through to check for Logic's failings so you might as well listen in real time. If you're anything like me that makes you notice a million things you should have fixed before bouncing. Cmd+'.' is your friend here. And patience.
