Adjusting Clip Gain Using Stream Deck Plus Knobs

By Gabriel Levi @Gabriel_Levi

    I would LOVE to be able to adjust the gain of a selected clip using the gain control in the region dropdown menu (where I've applied +7.3dB of gain) using the Stream Deck knobs. I searched for this command but couldn't find what I was looking for. Let me know if you think this is possible!

        Update: I actually created my own macro for this. I created a key command inside Logic for "Region Gain +0.1" and "Region Gain -0.1" and assigned those key commands to the Generic Knob Commands preset. To my surprise it actually works! This is gonna be so handy when doing some manual clip gaining.

              If you happen to implement this in the SoundFlow Logic package, the one thing that would make this a million times better is being able to make the +/- values variable. 0.1 dB is a little too fine for my tastes but 1.0 dB (the only other available option) is a little too extreme. Let me know :) Thanks!

                I've added this request for consideration... Hopefully, I can make this work, I can see how handy this would be. :-)

                  Hi @Gabriel_Levi,

                  I finally got around to creating a function for setting and adjusting selected region gain in Logic Pro.

                  Right now it requires the Region inspector "Gain:" slider/entry field to be visible.

                  Here is the function...

                  /**
 * Adjusts or sets selected region gain in a Logic Pro.
 * 
 * @param {Object} args
 * @param {'Set'|'Adjust'} [args.mode] - The mode of operation. Use "Set" to set an exact gain value, or "Adjust" to adjust the gain by a delta.
 * @param {number|null} [args.targetGain=null] - The target gain in dB. Required for "Set" mode. Ignored in "Adjust" mode.
 * @param {number|null} [args.delta=null] - The amount to adjust the gain by in dB. Required for "Adjust" mode. Ignored in "Set" mode.
 */
function setRegionGain({ mode = "Set", targetGain = null, delta = null }) {
    const logic = sf.ui.logic;
    const inspector = logic.mainWindow.inspector;

    const regionGroup = inspector.children.whoseRole.is("AXList").first.groups.find(g =>
        g.children.whoseRole.is("AXStaticText").whoseValue.is("Region:").first.exists
    );

    if (!regionGroup) {
        log(`Could not find the tracks region panel`);
        throw 0;
    }

    const rows = regionGroup.scrollAreas.first.children.whoseRole.is("AXOutline").first.children.whoseRole.is("AXRow");
    const gainRow = rows.find(e => e.children.first.value.value === "Gain:");

    if (!gainRow) {
        log(`Could not find the region gain slider.`);
        throw 0;
    }

    const slider = gainRow.sliders.first;

    let newGainValue;

    if (mode === "Set" && targetGain !== null) {
        // Calculate target gain value
        newGainValue = targetGain * 10;
    } else if (mode === "Adjust" && delta !== null) {
        // Calculate new gain value based on adjustment
        const currentGainValue = slider.value.doubleValue; // Already multiplied x10
        newGainValue = currentGainValue + (delta * 10);
    } else {
        log(`Invalid mode: ${mode}. Use "Set" or "Adjust".`);
        throw 0;
    }

    // Set the slider to the calculated new value
    slider.value.doubleValue = newGainValue;
}

                  Example use cases for the function...

                  // Set to target gain +10.2
setRegionGain({ targetGain: +10.2 });

                  // Set to target gain -5.5
setRegionGain({ targetGain: -5.5 });

                  // Increase by 0.1 dB
setRegionGain({ mode: "Adjust", delta: +0.1 });

                  // Decrease by 0.1 dB
setRegionGain({ mode: "Adjust", delta: -0.1 });

                  // Increase by 1 dB
setRegionGain({ mode: "Adjust", delta: +1 });

                  // Decrease by 1 dB
setRegionGain({ mode: "Adjust", delta: -1 });

                  I plan on adding this to the Logic Pro package at some point but I thought I'd share it in case you want to use it till then.

                  I also plan on making this into a Meta Command for smooth control with the Stream Deck+ knobs.

                  Have a great weekend.

                      DUDE! Incredible!! Thank you for keeping this idea in mind, will be so handy. I'm not 100% how to use this code. I see an option to convert a macro to script, but not how to convert a script into a macro. Let me know where I should look! You rock.

                        You could make a command template out of it. But for simple use follow these steps.

                        Create a new script and name it "Increase Region Gain by 1 dB". Then add the following code.

                        /**
 * Adjusts or sets selected region gain in a Logic Pro.
 * 
 * @param {Object} args
 * @param {'Set'|'Adjust'} [args.mode] - The mode of operation. Use "Set" to set an exact gain value, or "Adjust" to adjust the gain by a delta.
 * @param {number|null} [args.targetGain=null] - The target gain in dB. Required for "Set" mode. Ignored in "Adjust" mode.
 * @param {number|null} [args.delta=null] - The amount to adjust the gain by in dB. Required for "Adjust" mode. Ignored in "Set" mode.
 */
function setRegionGain({ mode = "Set", targetGain = null, delta = null }) {
    const logic = sf.ui.logic;
    const inspector = logic.mainWindow.inspector;

    const regionGroup = inspector.children.whoseRole.is("AXList").first.groups.find(g =>
        g.children.whoseRole.is("AXStaticText").whoseValue.is("Region:").first.exists
    );

    if (!regionGroup) {
        log(`Could not find the tracks region panel`);
        throw 0;
    }

    const rows = regionGroup.scrollAreas.first.children.whoseRole.is("AXOutline").first.children.whoseRole.is("AXRow");
    const gainRow = rows.find(e => e.children.first.value.value === "Gain:");

    if (!gainRow) {
        log(`Could not find the region gain slider.`);
        throw 0;
    }

    const slider = gainRow.sliders.first;

    let newGainValue;

    if (mode === "Set" && targetGain !== null) {
        // Calculate target gain value
        newGainValue = targetGain * 10;
    } else if (mode === "Adjust" && delta !== null) {
        // Calculate new gain value based on adjustment
        const currentGainValue = slider.value.doubleValue; // Already multiplied x10
        newGainValue = currentGainValue + (delta * 10);
    } else {
        log(`Invalid mode: ${mode}. Use "Set" or "Adjust".`);
        throw 0;
    }

    // Set the slider to the calculated new value
    slider.value.doubleValue = newGainValue;
}

// Increase by 1 dB
setRegionGain({ mode: "Adjust", delta: +1 });

                        Create a second script and name it "Decrease Region Gain by 1 dB". Then ad the following code.

                        /**
 * Adjusts or sets selected region gain in a Logic Pro.
 * 
 * @param {Object} args
 * @param {'Set'|'Adjust'} [args.mode] - The mode of operation. Use "Set" to set an exact gain value, or "Adjust" to adjust the gain by a delta.
 * @param {number|null} [args.targetGain=null] - The target gain in dB. Required for "Set" mode. Ignored in "Adjust" mode.
 * @param {number|null} [args.delta=null] - The amount to adjust the gain by in dB. Required for "Adjust" mode. Ignored in "Set" mode.
 */
function setRegionGain({ mode = "Set", targetGain = null, delta = null }) {
    const logic = sf.ui.logic;
    const inspector = logic.mainWindow.inspector;

    const regionGroup = inspector.children.whoseRole.is("AXList").first.groups.find(g =>
        g.children.whoseRole.is("AXStaticText").whoseValue.is("Region:").first.exists
    );

    if (!regionGroup) {
        log(`Could not find the tracks region panel`);
        throw 0;

    const rows = regionGroup.scrollAreas.first.children.whoseRole.is("AXOutline").first.children.whoseRole.is("AXRow");
    const gainRow = rows.find(e => e.children.first.value.value === "Gain:");

    if (!gainRow) {
        log(`Could not find the region gain slider.`);
        throw 0;
    }

    const slider = gainRow.sliders.first;

    let newGainValue;

    if (mode === "Set" && targetGain !== null) {
        // Calculate target gain value
        newGainValue = targetGain * 10;

        // Calculate new gain value based on adjustment
