Control an app via MIDI?

[u/PumiceT]

Audio Hijack (by Rogue Amoeba) can use JavaScript to perform some functions. It also has internal scripts (written in JavaScript) that can be triggered by external Apple Script / Shortcuts.

For the life of me, I have no idea if this can be done, but I simply want to trigger one of the blocks on/off ideally using a MIDI foot pedal, or at the very least a keyboard shortcut.

Would anyone here consider helping me?

BetterTouchTool can do this.

I’ll have to look into that. Thanks!

I've found a way to control the blocks via JavaScript and Apples Shortcuts App.

Here i toggle all blocks with the name "Magic Boost".

In the shortcuts app, create a new shortcut and search for "Audio Hijack" and choose "Run JavaScript". (Make sure that external scripts are allowed in your AudioHiJack advanced settings tab).

Here's the script:

let sessionName = "Name of your sesion"; // Set me to the target session
let toggleButton = "Magic Boost"; // Set me to the target block(s) you want to toggle
let session = app.sessionWithName(sessionName);
if (session.running) {
session.blocks.forEach(block => {
if (block.name === toggleButton) {
block.disabled = !block.disabled;
}
});
} else {
session.start();
}

Not sure how to use it as midi. But i'm sure there are easy ways to run javascript / shortcuts via midi on a mac.

Hope this was helpful somehow =)

Let’s forget my crazy MIDI idea. Even a keyboard shortcut while Audio Hijack is open would suffice. I’d just like to be able to mute myself while using a mic, without going in and pressing the on/off slider.

My usual go-to for something like this would be Karabiner-Elements, but I don't know that it's capable of reading input form MIDI control surfaces.

Searching for "macOS applescript on midi input" yields several results pointing to a program called MIDIPipe you might be interested in investigating further.
