logic workflow

Here's what I have going in lieu of a wet/dry mix knob.

I'm using the pre-fader send and a submix bus to mix my clean and effected (outboard) signal.

I'd rather assign a single knob to handle each wet/dry submix. Having to pull two faders on my controller to mix wet and dry signal is not ideal.

For example: I should be able to go from 0 (100% Bus 1, or totally dry) to 64 (50% Bus 1 and 50% Bus 2 aka wet/outboard) to 127 (100% Bus 2) on a single knob or controller assignment.

There must be a more elegant solution. Any recommendations?

  • I may not be understanding fully, but can't you just use the mix/bypass on the EQ insert?

  • Yes, that's why I'm using a pre-fader send. Potting up the EQ fader (Bus 1) mixes the clean signal in, but it's not proportional to the Wet side (Bus 2). Basically, I need to operate the second fader (Bus 2) if I want more than 50% dry signal (If I want 75% dry and 25% wet I have to pot down bus 2). It's no tragedy, but a simple wet/dry mix knob is a nice intuitive thing. Most plugins already have them, but Logic's I/O plugin does not (afaik). I'm not looking for a simple on/off bypass which is very easy to accomplish.

  • I get that it's not what you're looking for, but could you use another EQ? I'm not a Logic user, so I can't really suggest anything else, sorry. For example MEqualizer (free from Melda Production, see here) has Wet/Dry mix, and is available as AU.

  • I suppose something could be rigged up in the environment or under controller assignments that maps fader 1 to 0-64 and fader 2 to 65-127, but I'd prefer a simpler solution.

  • I have plenty of plugins already that have mix knobs. I'm trying set up an equivalent for Logic's I/O plugin so I can do a wet/dry mix with my outboard gear.

Ok, figured this out on my own:

Quick and dirty: Assign the two faders you want to crossfade to the same control, then set the multiply in the advanced assignment settings (Command+L) to -1.01 and 1.00 for the two faders respectively.

Nice: Get MRatio (http://www.meldaproduction.com/MRatio) and sidechain in the track you want to crossfade. Lots of control over curves, modulation, ratios, etc. This is what I'm doing.
