Ganging (linking) faders on several instances of a plugin

Post by aquataur »

Hi,
I am currently working on a thing that asks for two consecutive (equal) plugins, and I want to gang their faders.
I saw this in Reaper with Reacomp, and it works via MIDI. Two instances of a plugin on a track see each others faders on the list of available MIDI controls.
It is similar to midi control in Mixcraft, and while I manage to create a MIDI control that moves the fader, the fader won´t move the MIDI control element. Moreover each instance only sees its own faders. The CC number seems to do nothing.

Maybe somebody knows a workaround. Thanks.

Hi,

Mapping the faders to the same MIDI control CC isn't what you want?

Thanks for your reply.
I can map both instance's faders to the same CC number, but only one moves.
I don´t have an external device that produces MIDI.

Can you be more specific? Two instances of a plugin on a track sounds like you have the same reverb plugin, for instance, added multiple times on 1 track.

Do you mean you have multiple tracks each with the same plugin and you want to control the same dial/fader etc. on all of those instances of that plugin?

And you mention Reacomp which is a compressor so it's hard to understand what you are asking. What does Reacomp have to do with multiple plugin faders in the context of your question?

As a general answer, if you want to control multiple faders/dials,switches etc. on multiple plugins even across multiple tracks and you don't have a MIDI controller, you can do it as a multi-step process:

1. Use a program like loopMIDI to set up a bunch of virtual MIDI ports. Start by setting up 2: Mixcraft In and Mixcraft Out
2. Make sure they are added to preferences as MIDI input selections
3. Create a virtual instrument track that only has clips with MIDI CC values. This will essentially be your contoller track. You can add as many CCs as you want to the clips on this track. no need to add notes
4. In the instrument assignment for the controller track, add an External MIDI Device. In fact add as many as you need if you are sending to different channels or different tracks. If it doesn't matter and any track can receive the data, one External device will do. This will be Mixcraft Out that you created earlier. Set the MIDI Input for this controller track to Mixcraft In. You can set any channel you want. We're doing this to eliminate feedback from Mixcraft Out so you don't want the input set to the default of "All MIDI Devices"
5. On the rest of your tracks, add as many plugins as you like. For each track that will receive a CC message, set that track's MIDI input to Mixcraft Out. We want the output from our controller track coming into the track(s) that have the plugins we want to control.
6. Add as many MIDI controllers to the plugins as you need. Map the faders/dials/switches etc to the specific CC numbers that your contoller track is sending out.

If you set everything up correctly, when you hit play and reach a clip on the controller track that has all of the CCs on it, all of that information will be transmitted to those tracks that have the Mixcraft Out assigned as their input MIDI device. The faders on all of those plugins that you set up will adjust according to the CCs that are being sent.

...but if you were looking for a way to use the mouse to spin a dial or move a fader on one plugin and hope that that moves the slider on another, it can't be done live. The controls on the plugin transmit directly to the plugin and not outside of it. There's things you can do with automation or transmitting MIDI information as in the previous post. Or you could use something like "virtual MIDI controller" http://www.virtualmidicontroller.com/vmc.html or an actual hardware controller.

Thank you for your reply.
I was indeed trying to daisy-chain two compressors and link some of their controls.
This does not make sense normally, but refers to an attempt made here that tries to eliminate a subjective "flaw" in Reacomp by daisy-chaining two instances.

It has turned out that the author of the video was right in his observation of a certain behaviour, but wrong in his conclusion that this is a flaw.
In other words - the problem has diminished.
See here, chapter 6.5 if you are interested.

Thanks,
