I'm working on a live show where I'm playing the score for film live, building it in loops & layers and also semi live-editing the accompanying video. 

One thing I've needed to do is to be able to hit a different midi pads throughout my setup that each can send a trigger to Resolume (VJ software) to play the next column of visuals on the next beat #1. Resolume has a device called Parameter Forwarder that sends a signal from Ableton to Resolume, so I've just created a very simple patch that can send the Parameter Forwarder a bang immediately when I hit a midi pad, or have the bang wait until the next beat #1. 

I am a total Max noob, but I figured it out enough to create a very basic patch and get it working most of the time, but there are still a few gremlins in the patch that are coming back to haunt me now that I'm starting to play the show for people live. Here are the issues: 

I've asked ChatGPT which had some thoughts but honestly I don't understand Max well enough to be able to implement the ideas. I would love to learn Max fully someday but I'm really daunted by the thought of it currently. I'd be super grateful for any insight you have. This patch is really important to this show that I'm making and I'd be happy to pay someone for their time helping me to make it more robust. I'd also be happy to do some kind of skill swap, I've learned a ton about Ableton and Resolume for this show and have been a filmmaker & video editor for 15 years in case any of that is helpful to you! 

Here is the patch that I created. I've also attached a photo showing how it's setup in Ableton. (First row are midi mappable buttons that send a next column signal to Resolume, second row of big circles send a next columnn signal to Resolume on the next beat #1)

and here is a little more info for how the parameter forwarder works from Resolume's website

thank you so much for your time reading this, and thank you in advance for your help! i really appreciate it.

I have a patch that uses JS, on different systems it crashes Ableton Live, but I found that if you open the patch edit mode, this device works fine. 

What could be the problem of such behavior? Help me to figure it out. 

Also maybe someone who understands Java Script could help me with creating a copy using standard Max MSP objects instead of JS code.

in certain environments or patchers within projects, 

 simply does not fetch/output any information and does not 

 at all. Since I don't know its internal architecture I have no means of understanding what might be messing with it. The current patch in question has many dependencies, mostly JS-files. I somehow assume something is happening during load of the project, but it is total guesswork and speculation. Anyone else experienced this? Let alone fixes?

I'm working on a project for my exam and I need to integrate the OpenWeatherMap API in Max 8. The goal is to check the weather of a city (Milan in this case) and determine if it's raining or not. If it's raining, the result should be 0, otherwise 1.

I'm using the js object to write the JavaScript code, but my script doesn't work as expected. Here's the code I wrote:

// Configura API e città
const apiKey = "MYAPIKEY"; // Chiave API // la chiave api l'ho rimossa per privacy
const cityId = "3173435"; // ID di Milano
const apiUrl = `http://api.openweathermap.org/data/2.5/weather?id=${cityId}&appid=${apiKey}`;

// Funzione per verificare il meteo
function bang() {
    fetch(apiUrl)
        .then((response) => {
            if (!response.ok) {
                throw new Error(`Errore HTTP! Stato: ${response.status}`);
            }
            return response.json();
        })
        .then((data) => {
            // Verifica se c'è pioggia
            const isRainy = data.weather.some((w) =>
                ["rain", "drizzle", "thunderstorm"].includes(w.main.toLowerCase())
            );

            // Risultato: 0 (brutto tempo), 1 (bello)
            const result = isRainy ? 0 : 1;

            // Output del risultato
            outlet(0, result); // Invia il risultato all'uscita 0
        })
        .catch((error) => {
            // Output dell'errore
            outlet(1, `Errore: ${error.message}`); // Invia l'errore all'uscita 1
        });
}

Any suggestions would be really helpful! I want this project to be as complete as possible for my exam.

Hello, I want to use mgraphics offscreen (not jsui) to pipe into a jit.gl.pbr texture.  I need to maintain the transparency.  I have this working using in a jsui using a modified version of Darwin Gross's patch-a-day (

). But when I try translating the same thing using to use an offscreen context of mgraphics I'm not able to clear the screen so everything just accumulates.   

In the jsui version Darwin is sending a pattern(pop_group) > matrix out.  I don't understand why this is working in the jsui version and not the offscreen version.  Anybody know? 

offscreen Mgraphics > jit.gl.texture - can't clear screen

I'm making a dynamic UI, that needs to have <n> rows of specific UI elements, more or less like this:

jit.cellblock works for a lot of my needs, specifically that I be able to keep the displayed data elements in sync with a coll, and that it should show scroll bars if the number of rows exceeds the allotted vertical space in my UI.  Also, the number of rows is dynamic; rows can be added or deleted by the user.

However as we know, jit.cellblock can only display textual values, and not UI elements as above - thus my post.  I could probably brute force this somehow with dynamic scripting of the addition/deletion of bpatchers that contain the row of UI elements, but wondering if anyone has an imaginative different approach to make this be more easily accomplished.

I've been playing around with a patch where I run a list of numbers into a slide object, then scale the result to the range of the original list. But I noticed I wasn't getting the results I expected from the scale object, even without the slide object and the scale set 1 to 1 so that it should output the original list unaltered. Everything works as expected if I use floats, but I need the final list to be integers. The problem persists if I convert the list to integers after the scale object, even if the conversion is from e.g. 1.0 to 1 (int).

I have a patch that I need to ensure stays open during performances, is it possible to block any accidental closure attempts with additional text confirmation?

I attempted using a close bang with dialogue, and this "works" but by the time the close bang detects the patch close and text dialogue opens, the patch is already closed.

Hello and happy new year to everyone. Cheers  from Bordeaux! 

I would like to integrate a javascript program into max/msp, hoping that it will work in max for live.

To launch it I use the Processing software in Javascript mode.

The goal will be to get in max4live, the phases of each of 10 balls that we see rotating around a circle.

I explain at the end the purpose of this program

Here you can see the program made with Processing

// Simulation of coupled oscillators network in JavaScript using p5.js
let networkSize = 10;
let stepSize = 0.05;
let noiseLevel = 0.2;
let radius = 75;
let coupling = 0;

let time = 0;
let phases = [];
let naturalFrequencies = [];
let velocities = [];
let accelerations = [];
let couplingMatrix = [];

  createCanvas(200, 200);

}

  background(220);

  coupling = map(mouseX, 0, width, -10, 10);
  setCoupling(coupling);

  drawOrderVector();
  updateNetwork();
}

    accelerations.push(0);
  }

  for (let i = 0; i < networkSize; i++) {
    couplingMatrix[i] = [];
    for (let j = 0; j < networkSize; j++) {
      couplingMatrix[i][j] = coupling;
    }
  }
}

    fill(255 / (i + 1), 0, 255, 50);

  }
}

  }

  }
  return derivative;
