Getting an error in "How to control volume faders in Pro Tools using a MIDI controller. "

Hi Ryan,

I just checked your account. It looks like you may be trying to run this script by clicking Run Command?

The idea is that you need to add a MIDI trigger to the command (MIDI Faders) so that the script will be run every time MIDI is received.

You're seeing this error because the script tries to read which MIDI was received, but it can't since it's not being run by a MIDI trigger.

Hey Chris,

My first CC number is 74 instead of 7. So I replaced that in your code and now only the first fader is working. The reason being, my faders aren't numbered with a + 1 increment. My numbers are the following:
Fader 1: 74
Fader 2: 71
Fader 3: 81
Fader 4: 91
Fader 5: 16
Fader 6: 80
Fader 7: 19
Fader 8: 2

I'm assuming that this part of the code is giving number 75 to the second fader correct?

But my 2nd midi number is 71 instead.
I changed it to the following but it stopped working and now when I move fader one I get an error

error is:

That's your original code.

const firstFaderCC = 74;
const numberOfFaders = 8;

let m = event.trigger.midiBytes;
let m1 = m[0], m2 = m[1], m3 = m[2];

if (m1 == 0xb0 && m2 >= firstFaderCC && m2 <= (firstFaderCC + numberOfFaders - 1)) {
let val = m3 * 127;

sf.midi.huiFader({
faderNum: m2 - firstFaderCC + 1,
value: val,
touchAndRelease: true,
});
}

that's what I tried to do:

const firstFaderCC = 74;
const numberOfFaders = 8;

let m = event.trigger.midiBytes;
let m1 = m[0], m2 = m[1], m3 = m[2];

if (m1 == 0xb0 && m2 >= firstFaderCC && m2 <= (firstFaderCC + numberOfFaders - 1)) {
let val = m3 * 127;

sf.midi.huiFader({
faderNum: m2 - firstFaderCC - 3,
value: val,
touchAndRelease: true,
});
}

Thanks for the code!

Still, only the one fader work whenever I "Ctrl" + "Shift" + Click BUT here's the new thing :
It's always the midi trigger that works. For example, If I use my 3rd midi knob (that has a value 81) for the midi trigger, then only the 3rd fader will work. If I use the first midi knob then it's only the first fader that works.

No, I got All channels. The way I resoled it is by creating 8 different Midi scripts one for each fader. It worked :) I know it's not ideal but for now it's fine.
Quick question, is it possible to link midi knobs to the EQ7 in Pro Tools? I would need that much more than volume. Is it doable?
