Photoshop and midi controller

I'm bringing this topic up from the dead because, well it's valid.

I woujld like to propose that photoshop include:

- integration of midi as an extension of keyboard shortcuts

- Being able to assign these to actions

- Map sliders for HSL/RGB/Brightness/Opacity

- Being able to plug in apps like Metagrid directly so they can directly call actions without a hotkey assignment.

With the popularity of applications like Metagrid/Streamdeck/Keyboard Maestro, etc I can't understand how this hasn't been implemented. I have approximately 50-100 different actions in photoshop and along with all the keyboard shortcuts, it's hard to keep track which is why i love digital keyboards. Not being able to map these directly slows everything down, even though I have actioned what I can, run a tablet, and use keyboard maestro and Metagrid.

Come on Photoshop. You got this - please add it.

I think MIDI would be usefull if you consider to;

-control wheels and sliders (if you send hotkeys with you wacom wheel you can experience that there is a lag sending hotkeys)

-have a visual feedback on your midi controller (ex: the use pressure state is ON? OFF? con you send back this state to my midi controller?)

If there is some Adobe coder reading that post please write to me at:

For anyone interested, this is THE answer!!!:  http://controllermate.com/  It allows you to fully change the buttons of any connector controller, including the internal keyboard.  It has been AMAZING for combining several steps into a single key press!  Check it out if you're interested.  Then you can explore external controllers to command.  These X-keys look pretty good and come in various sizes:  http://www.piengineering.com/xkeys.php 

Graphics tablets (like wacom) use a number of buttons and keys, and people use them all the time with Photoshop.

But mostly they are emulating the keyboard.

In the realm of graphics, I have seen MIDI used for live performance capture of animated characters/puppets. But I cannot imagine how this would be useful to an image editing program. If there is a pre-defined "process", then there may not be a need for the live improvisation of an artist using MIDI controls. There is already an ability to run actions based on hotkeys assigned to your keyboard.

Can you give a very basic example of how you would see this working?
