APC40 Mk I Custom Control Surface for Logic Pro - Mac OS

Mouse_SF

I’ve been wondering if anyone here might be interested in this project I’m dialing in, it’s not ready for the public quite yet, but should be pretty soon. Here’s the summary on Logic Pro Help:

I’m more than happy to share techniques and methodology for those who are interested.
Enjoy,

Seems really cool. I don’t have one of those, but I do want to learn more about midi mapping for midi controllers. I foolishly bought a Nektar Panorama, which is supposed to come with easy mapping for Logic, and I could never get it to work properly beyond OS X. I mean, I could manually set it up I guess but it’s supposed to just work.

Anyway, even though I don’t own one, I’m still super interested in your project. Techniques and methodology. You seem to be very skilled. Nice work either way.

APC40 Mk 1 Customized modeless Control Surface for Logic Pro with full LED feedback 11/17/23

Here’s a few more details on the above post:

Outline
I’ve had a goal of using my APC40 with Logic as a customizable surface for a while, and wanted the expanded functionality Ableton provides via its Remote Control Scripting. It’s a big ask. Ive been working on this for a few years now in many forms and have kind of stumbled into Wonderland. It goes without saying that this type of Modding should no be attempted unless you have a pretty good understanding of Logic. I’m a 26 year veteran user. Here is the General Outline of how this works:

• The APC40 should be in Mode 1 (Ableton Live Mode, 0x41)
• The APC40 inputs into Logic and is interrupted at its input in the “Cables & Ports” Environment layer, routing it to an Environment Layer called “APC40 Mods”. I use these “intercepts” frequently for many purposes.
• There’s a lot going on in the APC Mods Environment layer, but the point is, after all the modifications this layer outputs to an IAC Bus named “APC/LPX Mod IAC Bus” and a few things route directly to the APC40.
• I have installed a Control Surface for a Novation Launchpad Pro Mk3 with its input set to APC/LPX Mod IAC and its output set to APC LED Return IAC. It is important that you DO NOT CHANGE THESE SETTINGS. It will destroy the template. Never rebuild your Control Surfae Defaults, and back up your .cs file regularly. The CS file ONLY updates when you quit Logic.
• The APC/LPX Mod IAC Bus sends all this data back into Logic, where it triggers Control Surface Assignments in the Top “No Mode” modeless assign area where all your CMD-L Learned Assignments go by default. A few commands are triggered in the LPP3 Control Surface and some LPP commands have been cleared of assignments for clean operation.
• Shift + Record Enable 8 sets the Track Knobs to PAN, the knob select buttons enable AUX 1-4, and while Shifted enable AUX 5-8 on all 8 tracks in the bank
• I’m also fine tuning a Function Map and onscreen display for user ease.

The Grid Mapping Syntax:
It took a minute to figure out a sensible data flow for the grid map - this order works
The feed is an intercept of the APC LED Return IAC Bus.

That is a very cool project. Thanks for sharing it.

Thanks for providing more information. I hope to one day be as knowledgeable as you are with this stuff.
