A question about Midi Mapping VST synth parameters

Hi All,

 

So I like to layer my lead synths and then assign all the filter cutoffs to 1 knob/dial on my midi keyboard which is the Alesis A49. I can do this in studio one and in Cubase and was wondering if this is possible in logic? The idea is very simple, with one dial I can lower the cutoffs and raise them, without having to have all the synths open etc at the same time, it just always controls whatever I set the dial to controlling.

 

Can this be done in Logic, I have worked out how to assign the filter cutoffs to the dial on my midi keyboard, but it seems to only be able to do one at a time. Also in studio one and cubase I can set how much I want the filter cutoff to open up for the individual synths, so say on plucks it only opens up half way once the dial on my midi keyboard is fully open. I can like map out custom ranges for the parameters.

 

Can this be done in Logic in any way?

Yes, simply learn them, and when Logic complains this assignment has already been learned, just click "keep" or whatever the wording is, and all matching assignments will work (ie you can control four different parameters from the same control).

 

Remember you have different instruments on different channels though, so you need to be careful about targetting the correct channel strip for the assignment.

 

You can edit the individual assignments if you want to edit their ranges.

Hi sorry, but your explanation on the smart controls is way too complicated for media really haven't got a clue how to do it and tried following your link but yeah I cant do it.

 

In terms of the first method mentioned, like I said I assigned, the filter cutoff on 4 different spires to a nob. Whenever I move the nob on my midi its only moving the cutoff of whatever the last synth was that I had selected. It won't seem to move them all at the same time. Any ideas?

Sorry could you explain how to do this? At the moment im touching the cutoff in spire, going to control surface and moving the dial, it then learns. It says its already assigned etc so I put keep. How do I do it so that the one knob controls the different cutoffs in the different synth layers? Im really struggling here and feel like ive tried everything.

 

As I said it seems to only control the cutoff of whichever synth I have open. Maybe if there's a way to have all the different synths open at the same time instead of just 1 by 1 It can do what I need it to do? This seems extremely frustrating and complex compared to cubase/studio 1

Also I tried following the guide in the link you posted step by step. So as soon as I try to assign one of the smart controls to any dial on my midi keyboard it won't work.It says in the link you posted after I click learn and start moving the dial, the smart control should move as well but this doesn't happen.

 

Honestly it might just be easier to use automation than this frustrating experience.

You must be doing something wrong, it should be very easy to do. Move the dial all the way down and up?

 

Or maybe your knob on your controller is not sending any MIDI data, which would mean it's not being detected.

Okay so I can assign the dial on my keyboard to control the filter cutoff. But it can only control one cutoff at a time, this seems to be dependant on what track I have selected. In terms of the link you sent, the area that's not working or step, is when I try to assign the dial on my midi controller to the smart knob. Like in the box where you have to assign it, once I touch the dial it fills with text (im guessing of whatever the midi command etc is) but it doesn't move the smart control dial.

Did you make sure you select a track OTHER than the one you're assigning?

Ok that's odd, I'm not sure why you're experiencing this. Maybe it's because you're trying to do two assignments at once (one through the controller assignments, the other through the Smart Controls). Let's pursue the first option then for now.

Ive tried selecting all the tracks, tried selecting the track stack, mapped all the filter cutoffs etc to the same knob and yeah can only control 1 filter cutoff at a time. Im not sure if this would cause issues but I have some other midi devices attached in my studio, namely the fader port and the Softube console one as well as a usb midi going to the Moog and a UM one controlling my JP8k midi transit.

Nope that doesn't work either. If I select another track whilst its playing and turn the dial none of the filter cutoffs move.

I would start over fresh: there's no reason that it wouldn't work on your system.

 

First hold down the Option key while you choose Go > Library in the Finder. Open your Preferences folder, then delete the com.apple.logic.cs file.

 

Now open your Mixer. Select a track that you will not assign (say, track #7). Make the assignment on the desired track, that is not selected (say track #1). The assignment to the track #1 should work without needing track #1 to be selected.

How about that:

  • inserting a Scripter in MIDI Fx inserts on a blank instrument track,
    set it to Midi to Plugin parameter mode,
    Set the cc control number of your knob (in the Input Type option),
    Select "learn plugin parameter" in Target 1,
    click on you Filter cutoff of your instrument to assign it to the cc knob,
    Repeat the process for each instrument (you can set up to 4 target, if not enough insert another scripture plugin)

 

Normally, if your blank instrument track is selected, adjusting the dedicated knob should affect all assigned Filter cutoff.

 

Hope it helps!
