Logic Pro: Assigning Volume to external MIDI controller

wingwizardwingwizard
in Logic Pro

I’m rubbish and quite new at anything complex MIDI. I was wondering if it was possible to assign the volume in logic to a particular knob etc externally.

Here’s what I want:

I have a korg micro key air (amazing amazing but on a separate note Bluetooth not working with iPad, works with android phone….)

It has pitch and mod wheels. I can Connect also a korg nano kontrol by plugging both into Amazon usb splitter thing then that through the Apple usb adapter. Hopefully this is ok

So when controlling strings and things I would like to be able to manually control volume while playing chords. I want to assign volume to either the mod wheel on the micro keys or a control on the nano control so I can do swells and fades and just control orchestral stuff nicely as I play

I have no idea how to do this. Was googling but it’s so specific

I remembered as I typed there’s MIDI… uhh… what’s it called… MIDI learn. Do you need this to do what I want as I can’t see how to assign a specific control and don’t know if logic can. Thank you

    Right now Logic for iPad lacks the ability to e.g. map faders or plugin parameters to MIDI controllers. If the particular plugin you’re using supports MIDI learn (and has a volume control) you could map it that way.

    If the plugin has a fixed CC# for the volume control, you could traslate mod wheel to that CC# with a Logic Scripter script. I’m not really familiar with Scripter but I’d guess that someone out there has already published a script for transposing CC#s. By the way, CC stands for “control command”. You can send a MIDI CC with a target number of 0-127 and a value of 0-127, and that’s how MIDI mapping works under the covers. “Mod wheel” is CC#1, so your script would just have to receive a value for CC#1 and pass that value along to whatever CC# your plugin uses for volume. See https://www.paulcecchettimusic.com/full-list-of-midi-cc-numbers/ for a listing of common CC numbers. Different plugins and controllers will honor these “standard” CC#s to varying degrees, of course. The EU hasn’t gotten around to regulating CC numbers yet 😀

    Thank you. I actually ended up digging a bit last night and found out that if you add ‘modifier’ as a processing unit or whatever to the track you can assign a bunch of parameters - inputs to outputs which is this cc stuff haha. So it has a list of inputs and then outputs like mod wheel 1 as you mentioned then volume at 7 i think. It depends. And I’ve just noticed in inputs there is also learn MIDI so maybe it can pick up your MIDI controller?

    Sounds like you're on the right track, only question is if your plugin responds to CC#7. Good luck!

    You can always use a gain plugin and automate that if cc7 doesn't work.
