Currently, I'm sorting all my samples into two categories: those with a duration of 3 seconds or less, and those with a duration greater than 3 seconds, using the sfinfo object.

In my "master folder," which includes subfolders, I have approximately 16,000 samples. To gather their filenames, I employ a recursive search using JavaScript, resulting in an array of filenames. Subsequently, I feed this array into the sfinfo object to retrieve the length of each sample.

The process of obtaining the array of filenames takes around 3-4 seconds, which is efficient. However, the subsequent step, where sfinfo analyzes the files, is notably slow, taking approximately 3-4 minutes. During this time, Max appears unresponsive, with the spinning wheel suggesting a potential crash.

My query is whether there's a method to execute this task in the background or optimize the process for speed. Essentially, I'm looking for a way to offload this heavy-duty analysis to another thread or improve its efficiency to eliminate the unresponsive behavior.

I want to be able to send audio from the first instance of a device to any other instance within the instrument / effect thingy. BUT I only want it to send / receive for that track, so if I had multiple instances on another track it would not receive any sound from other audio/midi tracks. Any ideas?

My goal is to create a flexible M4L device that allows for dynamic swapping of effect chains within a structured signal routing setup (handled by Max). The audio signal enters the device from 

 and is split into two paths. One path remains unprocessed, while the other is routed through an effect chain. The specific signal routing beyond that becomes nontrivial and hacky in Live (but is simple in Max), which is why I want to implement it in Max rather than in a Live effect rack.

Ideally, I would like to structure the device such that I can load Live's native effects and third-party plugins to create arbitrarily customizable effect chains, much like a Live-native effect rack. I am considering options such as using 

 for loading effect chains dynamically or employing 

 for user selection. Still, I'm curious if some other approaches or objects might be better suited for this task.

Has anyone here worked on something similar or have any recommendations on how to implement this kind of dynamic effect chain swapping efficiently in Max for Live? Any tips on maintaining performance and usability would also be greatly appreciated!

I have some chords where I need to adjust each MPE pitch in some cents. 

How can I access the info displayed in Ableton Live in the MPE tab? I haven't found anything to control that from M4L yet.

However, there is no information on each MIDI note controlling its own MPE.

Hey guys. Complete beginner here. I was wondering if it possible to incorporate a selection knob into the stock Ableton multimapper that toggles each mapper on and off in series, such that only one is selected to be active by the knob at a time? The goal is to have each mapper premapped to a target in a project and to cycle through mapping targets with a macro knob so only one of my choice is modulated at a time.

I figured I'd use toggles and connect them to a knob somehow, I'm assuming there are if/then objects I can use for this? I'd have the knob have a range of 1-8 for example and use an "if knob = x" then "toggle on and the rest off" kind of logic. But being a complete beginner I have no idea if this is how it would be done nor do I know where to connect the toggles in this salad of routings

I'm working on a device that midimaps a surface control to some parameters, with a fancy fullscreen UI with big sliders and knobs... I named it OSC

I have a big live set with multiple track groups, each track group is one song with its own plugin... and each track group has its own OSC device.

The device is currently in use and working almost fine. Each one has its own setting thanks to the dictionary paramater_enable attribute.

BUT each time i open in Max the "original" OSC device, and save some modifications, its dictionary spreads to all the other running OSC devices and I have to set them again individually, which is a pain.

For each device to have an independant dictionary, I preceded the dict name with the magical "---".

I played a bit to try to understand, I noticed that the "---" is replaced by a 3 digit number which is not the device Id. Those 3 digits change in every single running device every time I save the original device, and subsequently the name of the dictionary changes, and lose all its data...

Is there a way to force each instance of the device to name its dictionary with a unique name it could then remember ? I dont want them to be saved into a file and recalled every time, I'm sure there's a straightforward and simple way to do this.

Long story short, I want to be able to modify the "original" OSC device without modifying the dictionary of other running OSC devices...

Hi. I'm trying to traverse the LOM from the current device in an arbitrarily nested drum rack and find the drum pad that the device belongs to. If I traverse upwards I end up hitting DrumChains and RackDevices but there doesnt seem to be an association where a device knows it's own drum pad. The main thing I'm trying to get here is the note assigned to trigger the device, which is only in the drum pad. 

It's kind of odd that a DrumChain lists the choke group and out note but does not list the note received

Hi, I would like to know if it is possible to have a Max midi audio device that also can receive audio from an audio track in Ableton. So basically I can access both the midi data received on the midi track where the Max device is and the audio data coming from the other audio track. I am not interested in outputing anything from this device, no midi and no audio should come out from this device. I just need the midi and audio signals to control some Jitter visualizations.

Is it possible to create an ableton audio clip from what is stored in a buffer~?

The idea is for this M4L plugin to live on the effect chain, and always be recording a 30 second loop. If I like the content that passed through, then I can save the content by creating an audio clip in ableton.

buffer~-to-audio-clip

Would be great to know if this is possible as well, especially since buffer~ already has a "writewave" option - it would be great if that exported WAV could be sent directly to an audio clip via the Live API and eliminate the intervening steps. Any ideas?

I have never tried this, but reading programmatically from a buffer is easy enough. Is there an M4L interface to write to an audio clip? I have a video of coding buffer i/o here - if there is an audio M4L api I could make up an example. https://youtu.be/_d0KHvh4V44

Ableton 12.0.5b have this. You can load a file into an audio clip if you give the full path of the audio file.
