leolabs / ableton-js Goto Github PK

Hello! Just came across this project and think this and AbleSet looks brilliant. Thank you for your hard work!

Would you consider adding a license to this repo so it can be used? I'm interested in playing around with this some locally and maybe using in combo with GoLang and web-assembly or something. Might be able to lend a hand with the repo as well if you'd be receptive to that. Thanks!

Sorry for such a noob question, but I'm stuck for a while now and can not find an answer.

I am struggling to select a scene. Although I was able to get selected scene by using
let selectedScene = await ableton.song.view.get("selected_scene");
I can't set selected_scene.

I tried these without any success:

  await ableton.song.view.set("selected_scene", 4724534408);
   await ableton.song.view.set("selected_scene", "4724534408");
   await ableton.song.view.set("selected_scene", { nsid: "4724534408" });
   await ableton.song.view.set("selected_scene", { "nsid": "4724534408" });
   await ableton.song.view.set("selected_scene", selectedScene)

the error that I get is UnhandledPromiseRejectionWarning: Error: Python argument types in None.None(View, int)

I also tried using sendCommand without success:

let res = await ableton.sendCommand("song-view", null, "get_prop", {
    prop: "selected_scene",
  });

Any help would be appreciated.
Thank you in advance.

Hi, this project looks really cool.

I have 5 samples in a folder. Via JS, I want to open an audio channel for each sample in the folder and add those samples to each audio channel in Live.

Is this possible using your library?

I looked at the unofficial documentation for the live API methods here https://structure-void.com/PythonLiveAPI_documentation//Live10.0.2.xml
but couldn't really see anything that indicated I could add channels and load clips into them by using their /path. I saw a lot of event listeners but not actions.

What am I missing?

Hi I've installed on OSX. I believe I've followed all the instructions, but whenever I call Ableton.song.get() I receive a timeout.

Here are the logs from Ableton:

0-03-04T13:51:10.619049: info: Python: INFO:_Framework.ControlSurface:619 - LOG: (AbletonJS) Starting on: ('127.0.0.1', 9001), remote addr: ('127.0.0.1', 9000) 2020-03-04T13:51:10.619076: info: RemoteScriptMessage: (AbletonJS) Starting on: ('127.0.0.1', 9001), remote addr: ('127.0.0.1', 9000) 2020-03-04T13:51:10.619238: info: Python: INFO:_Framework.ControlSurface:619 - LOG: (AbletonJS) Socket Event connect(None): null 2020-03-04T13:51:10.619262: info: RemoteScriptMessage: (AbletonJS) Socket Event connect(None): null

I don't see errors but 'connect(None): null seems a little weird. Any idea what is going on?

Hello,
I can't get to add "playing_status" listener, either to clipslot or clip itselft. Am I doing this correctly?

ableton.song.get("scenes").then(async (scenes) => {
  const firsScene = scenes[0];
  const clipSlots = await firsScene.get("clip_slots");
  const firstClipslot = clipSlots[0];
  firstClipslot.addListener("playing_status", (p) => console.log("status", p));
});

Clipslot works with listeners "is_triggered" and "has_clip", but not with "playing_status".

Is there a recommended practice to remove listener from clip or clipslot?

Thank you once again.

hey so I'm looking for a way to listen to each scene in my set, the number of clips it has, and whether they are recording, stopped, playing, etc.

It doesn't seem like the library has any notion of clips as of yet though, correct?

Hi I'm in the process of writing a grid control app similar to touchable.

when trying to get the mixer device of the master track with this code

  // Establishes a connection with Live
  await ableton.start();

  const masterTrack = await ableton.song.get("master_track");
  const mixerDevice = await masterTrack.get("mixer_device");

I get the following error

Process exited with code 1
Uncaught TimeoutError Error: The command track(live_140638798970484).get_prop({"prop":"mixer_device"}) timed out after 2000 ms. Please make sure that Ableton is running and that you have the latest version of AbletonJS' MIDI script installed and renamed to "AbletonJS".

In the Ableton log I see

2024-01-18T13:03:24.190397: info: Python: WARNING:AbletonJS:190 - UDP tick is lagging, delta: 1387.0ms

I am running version 3.4.1. I've tried re-copying the midi-script folder using the package.json script.

Goal: Trigger the first clip of the first track to start playing

Attempt:

    let tracks = await ableton.song.get("tracks")
    let firstTrack = tracks[0]

    let clipSlot = await firstTrack.get("clip_slots")
    let firstClipSlot = clipSlot[0]
    
    await firstClipSlot.sendCommand("fire")

Error:

UnhandledPromiseRejectionWarning: Error: The command clip_slot(10074456552).fire(undefined) timed out after 2000 ms.

From everything I've read, the command name should be "fire" with only optional parameters.

Am I missing something? I don't know what else to try...

Sorry for a beginner question, but I'm not familiar with TypeScript and I feel that the process for using this library is different from other Node modules that I've tried.

I'm not really sure where the example code in the readme should go. Do I need to build the package before using it in my own index.js file or how is it meant to be implemented? Maybe a more detailed "getting started" section in the readme could help or maybe I just need to read more about the fundamentals of this setup in general. :)

Hello!

I'm currently writing an app which uses your module and I face a literal wall of errors from it.

I also don't understand where this errors come from.

You find all changes which include your library on this commit

I attached a log file from my program which contains the mentioned errors.
errors.log

When I disconnect and reconnect Ableton I get the following events:

• Disconnect
• Connect
• Disconnect (unexpected)
• Connect (unexpected)

I looked into the JS code further and it seem like it may be a bug in the Python midi-script or further up as this is what I see in the raw messages coming into the handleIncoming.

I am using:

• Ableton Live 11 Intro
• Macbook Pro (M1 Chip) - Monterey v12.2.1

Hello, I have a small problem and I would be grateful if you could help me. I want to set the volume of tracks. But apparently for some reason I can do that with the library, I wrote track.get("mixer_device") which grants me access to the volume right? but then when I do mixer.get("volume") I get an error saying: mixer.get is not a function, thanks in advance :)

Hello,

the MIDI Remote script link in the README (Ableton's MIDI Remote Script) is broken. I get an SSL error ("This site can’t provide a secure connection"). Can you provide any alternative source for the information contained there?

Best regards,
Samo

Hi there,

it looks like lodash is not just a dev dependency but a runtime dependency of Ableton.js. When I do

import { Ableton } from 'ableton-js';

async function main() {
  ....
  const ableton = new Ableton();
  await ableton.start()
  ...
}

I get a MODULE_NOT_FOUND error (Error: Cannot find module 'lodash'). After installing lodash, everything works fine.

I think updating the package.json accordingly should fix this for all users of the library.

Best regards,
Samo

I just started out with this module so maybe I am missing something, but I noticed this:

I subscribe to 'current_song_time' like this:

const ableton = new Ableton()
ableton.song.addListener('current_song_time', t => console.log('Time:', t))

The Ableton doc is at 120bpm and I step to clock time 3.1.1 which gives me the output Time: 8.

The specs say this:

Live.Song.Song.current_song_time Property
Get/Set access to the songs current playing position in ms.

Shouldn't the output be Time: 4000 for this setup? The value seems somehow fixed to the bar counter, not the implicit time value. When I change the signature and tempo, the output stays the same.

Hello once again, thank you for such a cool module.
Do you think it would be possible to use ableton-js with React?
I am trying to use your module, but I get this error:

TypeError: dgram_1.default.createSocket is not a function
at node_modules/ableton-js/index.js:101

my minimal code looks like this

import React, { useEffect, useState } from "react";
import "./App.css";
import { Ableton } from "ableton-js";

const ableton = new Ableton();

function App() {
  return <div className="App"></div>;
}

export default App;

should I keep trying or is it impossible to use AbletonJS with React?
Sorry once again for noob question and thank you in advance for your time.

Hi,

First of all, thanks for your incredible work! I’m having a hard time figuring out where/how I can add event listeners to clips for a given song. Could you please point me to some documentation on how to access each name spaces’ observable traits?

E.g. I see that if I want Song-View traits, I need to go through ableton.song.view.addEventListener. How do I do the same for all the clips loaded up?

To reproduce, place a plugin or any other effect device on the Master track and run

const song = await ableton.song
const master_track = await song.get('master_track')
const devices = await master_track.get('devices')
  
devices.forEach(async function(device) {
  await device.set("is_active", false)
})

This results in

return functionCallback.rej(new Error(data.data));
                                        ^

Error: can't set attribute

    at UDP.onMessage [as onmessage] (node:dgram:930:8)

ableton-js/src/ns/device.ts lists 'name' and 'is_active' as settable properties. Setting the name (e.g. on an effect rack) works fine.

Tested on the latest version of ableton-js and Live 11.3.13

Can your framework check the actual master volume level? But not the fader lever but real-time output level.
I want to create some simple visualization app.

hi, thank you for this solution!!, is a very better for me)

please tell me if u know, how i can use "output_meter_left" data for visualize, im trying make self algorithm but attempt be fail, sorry for offtop, but i idk where i can ask this question, thanks for any reply!!!

I have a clip that I would like to place in the Arrangement View.

"Track" has the function "duplicateClipToArrangement", which takes the ClipID as an argument.. But how do I actually get that ID?

Hi! I've just updated to the 3.3.0 version of this library from 3.1.7 and am noticing some significant differences in latency.

Here is the code I'm using to test the latency:

const { Ableton } = require("ableton-js");
const ableton = new Ableton({ logger: console });

(async () => {
  let start = (new Date()).getTime()
  await ableton.start();
  let time = await ableton.song.get("current_song_time");
  console.log(time)
  console.log("all set")
  console.log(((new Date()).getTime() - start))
})()

I'm running this code on a fresh new Ableton project. When I do so on 3.1.7, the script takes ~35ms. However, on 3.3.0, the script takes ~300ms.

I am downgrading for now and can help with any debugging. Thanks for your continued development on this great project!

Hey! Firstly, amazing job on the library.

Secondly, I'm trying to get a clip name after having selected it like so:

let clip_slots = await tracks['main'].get("clip_slots")

clip_slots.forEach(async (slot) => {
    if(slot.raw.is_playing === true) {
      let clip = await slot.get("clip"))
      console.log(clip)
    }
});

I can't seem to find a way in the transformers, etc, to get the name of a clip, any advice would be much appreciated.

Thank you so much for your amazing work with this repo. It will open many new possibilities for projects I have in mind.

When I run the following code I get a warning from Ableton:

await clip?.removeNotes(0, 0, 4, 128);

It's not a big deal, because I can "Proceed" and disable the warning, but just wanted to make you aware.

Ableton Version: 11.3.10
ableton-js version: 3.3.2

Can't reliably reproduce it. Seems like it can happen on opening a new project but it also happened while working in a project. I have no ableton.on listeners in my script.

Creating a PR to resolve this.

Would sending/receiving midi signals be out of scope for this project?

I've played around with it a bit and was able to get them to send from Ableton in a rough way. Wondering if I cleaned it up and created a PR if that would be welcome or not.

Thanks.

I've been playing around with this repo - it's really cool!
Is it possible to create scenes with names/bpm attached? I can't seem to figure it out.

When I create a scene, it returns a String, but I cannot access that specific scene or perform any actions on it...like set name or tempo.

Would appreciate any help, thanks!

Hi, I'm enjoying this library very much.

One issue I've noticed (using Ableton 11) is that using set_notes on a Clip (and possibly other Set commands) will throw this error.

node:39754) UnhandledPromiseRejectionWarning: Error: Python argument types in
    Clip.set_notes(Clip, list)
did not match C++ signature:
    set_notes(TPyHandle<AClip>, boost::python::tuple)
    at Ableton.handleUncompressedMessage (/<path/to/project>/node_modules/ableton-js/index.js:186:41)

My JS code looks like this

    const tracks = await ableton.song.get('tracks')
    const clipSlots = await tracks[0].get('clip_slots')
    const clip = await clipSlots[0].get('clip')
    if(clip) {
      await clip.setNotes([{ pitch: 60, time: 0, duration: 1, velocity: 98, muted: false }])
    }

I've attempted to define a custom setter in Clip.py that converts a List to Tuple, but then it throws a similar type error

UnhandledPromiseRejectionWarning: Error: set_notes() argument after ** must be a mapping, not list

I've exhausted my rudimentary Python knowledge so I thought I'd raise a ticket, thanks! 😄

Hi. I have a problem when building a React application. Whenever I import and use your library I get the errors shown in the screenshot. Installing the necessary pollyfill packages and configuring webpack did not change anything.

Hey! Would love to get warp markers working for a personal project of mine. Has anyone started on implementing that or digging into how to get that to work? Otherwise, I'd be happy to knock it out. Thanks!

I suddenly get this error: Error: The command song.get_prop({"prop":"tracks"}) timed out after 2000 ms. Please make sure that Ableton is running and that you have the latest version of AbletonJS' midi script installed and renamed to "AbletonJS", listening on port 39041 and sending on port 39031.

After using the library for a month without a problem, it seems to have stopped working completely for the past two days. The problem started occuring when I accidentally installed all the packages again. I do obviously have Ableton running with AbletonJS as a control surface. I have been trying to find where exactly I had placed it, with the hopes of replacing it maybe that helps, but I can not find where I placed that remote script in Ableton, not at least where it was mentioned here or in other Ableton-sources.

I'm trying to create a new Midi Track using ableton.song.createMidiTrack(1), however, I get the following error:

Error: create_midi_track() argument after ** must be a mapping, not list

I'm using Windows and the Live 11 Beta (11.2.10b1)

EDIT: Also occurs when using Live 11 (not Beta)

I'm trying to set the pitch of a clip.

Currently I've tried this to no avail:

clip_slots.forEach(async (slot) => {
      if (slot.raw.is_playing === true) {
        let clip = await slot.get("clip");
        let name = await clip.get("name");
        let pitch = await clip.set("pitch", 20);
        console.log(track + ': ' + name);
      }
});

Thanks so much for releasing this library. It's much appreciated! From looking at the source code, and from the API documentation (https://nsuspray.github.io/Live_API_Doc/11.0.0.xml) I haven't been able to track down the command to export a Song as audio. Any chance you've come across it?

Hello,
I am having troubles finding documentation on the arrangement view and how to access and modify clips there.
I would like to write a script that synchronizes the midi data on clips in the timeline with a session view clip in a slot with the same clip name.
Currently I am not sure if anything like that can be done with the python api.

Thanks for the help and best regards

So I have a lot of tracks/scenes in my set. When I go to get clip_slots from a scene I get this message:

Error: error: (40, 'Message too long') at Ableton.handleIncoming (/Users/justin/My Files/Code/Music/Ableton/ableton-js/index.js:131:45)

any ways you can think of to trim down message size?

I'm fiddling around with ableton-js and got to a point where I would like to edit a tracks's sub routing.

Let's say I want to set it to my audio interface's stereo channel 3&4.

I tried to get the setter to work:

await track.set('current_input_sub_routing', 0)

This raises the error

(node:8883) UnhandledPromiseRejectionWarning: Error: Python argument types in
    None.None(Track, int)
did not match C++ signature:
    None(TTrackPyHandle, TString)

Do you have a hint how the parameter should look like?

Hi! First of all, thanks for this, it's an awesome library!

I'm having issues with timeouts, I'm doing a map of device parameters which have automation on them, which needs to be done on a large number of tracks, and i've encountered a couple of issues:

1. The AutomationState enum is incorrectly setup, the AutomationState.Playing should be on the second slot, not the third as it is now, and the .Overridden should be on the third one, to accurately reflect what's happening in ableton.
2. The mapping is not capturing all of the tracks, and i can't find a pattern in which it happens.
3. This is the most urgent one, the framework times out after 2000ms, so i've changed it to 20000ms, but the timeout still happens, even though i'm not quite sure why. I'll attach the code and the ableton project for you to test out, i might be missing something really obvious.

Thanks a lot, and thank you for this beautiful piece of software! :) Cheers!

PS. I'm using Ableton 11.0.12.
