Modulating parameters in an audio track?.

tahiche

I’m sure it’s been answered 1000 times and I’m afraid the answer is “NO”… Can you modulate audio fx parameters in a logic audio track?. Like the Modulator midi fx but for audio…

i don't get your question, sorry.

They’re asking if you can modulate FX parameters

I’m actually not sure, I haven’t tried it. But I imagine you can as you can modulate the stock effects parameters and parameters of other AU synths.

On an audio track?. I don’t think you can. The only way I know of you can modulate parameters is via a MidiFX slot, and you don’t have those on audio tracks.
Searching on this topic, it doesn’t seem like it’s possible on desktop Logic either. Wtf?
There’s a dodgy workaround that would work on iPad, it involves an instrument track with a sidechain-enabled plugin aimed at the audio track… Good to know but probably not worth the hassle.

I’m going to rename the post title, it’s certainly misleading. Thanks!

In case someone’s looking for a way to do this, I’ll include the little hack from the post https://forum.audiob.us/discussion/57484/modulate-audio-fx-in-audio-track-sidechain-midi-modulation-hack

Hi!
I made a little video after successfully testing this handy hack. We love hacks on iOS, don’t we?. Can’t live without them, even on mighty “Pro” 😜

Frustrated about the impossibility to add midi modulation for audio fx in Logic. Unfortunately you need a MidiFX slot, which are available for instruments but not audio tracks. Read somewhere about using sidechain for this purpose so I though I’d try it out. I believe it’s self-explanatory, you set the sidechain to “listen” on the instrument track and the audio track audio will route through the instrument channel, where you can add audio fx and apply midi modulation. Here I’m using the stock “modulator” but you could use mLFO, Brambros, or any other MidiFX auv3 to modulate audio fx parameters

Works pretty well. Not ideal that you need an extra track and I see no reason why this isn’t possible in an audio track, but it’s manageable. For tidiness you could add both audio (source) and instrument (receiver) track to a folder or summing stack.
You can also use it as parallel processing if you don’t mute the original track.
If you wanted to do this for a group of tracks, you’d just use a bus as the sidechain input

And it just occurred to me, big one!. It could provide midi controller support for audio tracks using @klownshed ’s trick

I know you can use something like KQ Voice plugins (Loopback), but I’d rather use stock plugins and this sidechain method seems very reliable.

I see this as sort a bus on steroids, with extra powers. Lots of possibilities, really.************
