Default Automation for track FX bypass (solved)

EDIT: This request has been rendered redundant by the new "Force auto-bypass on silence" options.

If a track has CPU heavy FX but is silent for most of a song, it makes sense to bypass those FX while the track is not contributing to the mix, especially when the cumulative CPU usage of a project is getting near the system breaking point.

Although it is possible to set up master/slave parameter modulation to bypass multiple FX from a single bypass switch (which can then be automated), this is fiddly to set up and awkward to maintain (if you add new FX you have to remember slave them too).

An automation envelope to toggle the track FX bypass button would be much better, providing an easy way to enable/disable track FX en-masse during a mix as well as an obvious visual cue as to the state of the track FX at any given time. This would be extremely useful for users (like me ) struggling with underpowered computers.

Please?

Wouldnt it create issues/cracking with the PDC kicking in/out? (assuming worst scenario: a plugin with latency)

You get that anyway if you automate the bypass for a single plugin. I'm proposing a shortcut to allow the same thing for all track FX at once. As with bypassing single FX, the transition points would just have to be placed where there's no audio. If you want smooth transitions, you automate the wet/dry params, not the bypass.

not elegant, but doable...

You could write a little "Action trigger" JS just for this, and put MIDItoReaControlPath after the effect (or use a MIDI hardware (or virtual Loopback) to fire a custom action.

The Js would have to know the track id, somehow. This could simply be a slider that you'd adjust manually, there might be some scripting magic that could make it automatic - not sure.

then, you'd just make the JS send a program change (or cc) and the macro would be assigned to that PC or CC message.

basically tie "Toggle bypass for track (x)" to MIDI channel(whatever), PC(x), and have the JS send that value.

(or just select track (X), and have toggle bypass for selected track on a different message.)


*you might have to turn this off when rendering - it might be automatically ignored - which is fine is this case. (as long as the FX isn't stuck OFF)

^^^

This request is for bypassing all effects on a track together with a single envelope, and this we don't have yet in Reaper afaik.

You say there's no audio where you want 0 processing, so make sure this is ticked:


Do not process muted tracks (muted tracks take no CPU time, etc)

Then automate the Mute parameter of the track.

No. I don't want to do that. I want an envelope to allow automation of the track FX bypass button.

cool. nice low hanging fruit FR. i was only just made aware that you could bypass FX instances with an envelope (thanks Darkstar!) and it's going to free up some resources. this would be a step further.

Nope. CPU is not released while the tracks is mute by automation. It make sense because if you're unmute the tracks without stopping playback, the plug in chain need to reload and it would be a total vortex of shit with PDC

If you want to have zero processing on a track during a track, you need to automate the bypass of all the plug in the track. You can also use a JS plug that do nothing and link the bypass parameter to all the bypass parameter of all the other plug... So, when you bypass the Fake JS, you bypass all the chain '

But in practice that's a PITA if you're changing plugins around on the track, hence the request for a simple (and probably easily implementable) envelope for the track FX bypass button.

ooh. wow. i've been doing this live for a while -- using action markers to mute/unmute entire folders that have entire songs and armed tracks in their children tracks while playing the project.

generally this is smooth, but every now and then you can hear the thing grind a little bit. i'm betting i'm hearing this "vortex of shit" you're referring to.

Not necessary as a feature of the DAW.

Why not simply use a plugin (e.g. find/do a JSFX) that has slider cross-fading between channels 1/2 vs 3/4, and pin-Routing the channels 3/4 to bypass the plugin in question ? Now the appropriate fader can easily be automated.

This wouldn't free up the CPU used for those plugins, or would it?

Correct.

If saving CPU is critical, track muting seems to be the way to go, but I suppose there will unintended artifacts.

Track muting is not the way to go. Toggling a track mute if muted tracks aren't processed tends to cause glitches. I don't want glitches every time I mute/unmute a track during the mixing process.

The ability to automate the track FX bypass would allow easy selective disabling of plugins at different points on the timeline. Of course sudden mass enabling of plugins would likely cause glitches too (though perhaps that could be compensated for) but that would be preferable to constant problems when performing the common task of mute/unmuting tracks for mixing purposes.

You can bypass any fx and automate this, of course.

As mentioned above, bypassing and completely disabling an FX will change the pdc of the track and hence result in glitches.

Yes, you can, but it's not so easy to bypass all FX on a track in one step, hence the feature request. I'm aware of all the possible workarounds. They all suck. Workarounds always suck, so please don't bring them up.

That fact, which I am well aware of, does not detract from the usefulness of the feature I was requesting in this ancient thread.

You suggested that in order to bypass all of a tracks FX simultaneously then muting should be used. If you want to do that then you need to disable processing for muted tracks, which results in glitches when mute/unmuting tracks, which is annoying. Toggling a track mute should not cause glitches.

If I disable a full track of FX by use of the proposed envelope, in order to free CPU when those FX aren't in use, glitches will of course occur when those FX are re-activated but that would be much more acceptable than glitches every time you mute/unmute any track that requires PDC.

Somebody might consider to invent a "crossfade" for the pdc if automation requires this. Supposedly a unique thing in the industry.

Yea and how is this different from just doing a regular byass of the only plugin on a track? Its not. Not all plugins need to be PDC'd either, depends of buffersize.
My point being, it should be doable and a nice feature!

I don't suppose the devs will implement a feature that definitively asks for complains from users that are unaware of the - not perfectly obvious - restrictions.

Not sure about the complaining part, again it's the same as bypassing one plugin only with latency.

This means deliberately replacing the plugin by a delay (keeping the same pcd). Doable but not "obvious".

I suppose to have the FX bypass balance work perfectly, the dry path would need to impose the pdc, anyway. So an option to switch off the FX instance when the balance is set to zero seems a nice addition, and - as that would be off by default - the arising glitches would be obvious to the user.

Bump for an automation envelope for bypassing all FX on a track. I have some very extensive live projects that use a lot of FX bypass envelopes and it gets super messy and frustrating when I add something. Having an envelope which does the equivalent of turning off the entire FX chain for a track would be super handy.

I'm hanging around my live projects and automations, and I did not find this function. As well as the lack of rec arm automation (Does that request exist?)
Very bad surprise(

Bumping this again years later!
Those not getting it are not considering live-show applications.

Linking the bypass parameters of every plugin on a given track works (I've been doing it for many years) but life would be so good if this didn't have to be done for. every. single. track. in. an. entire. live. show.

I don't see how FX bypass is useful for live shows (but you might do that completely different than I can imagine).

For Live stuff "SWS LiveConfigs" often is very helpful. Maybe its worth a try.
