Strange init problem

I’ve been looking at a problem for quite a while now and i can’t figure out what happens exactly, so i hope someone here has some ideas. I put a screenshot of the relevant part with some output in the max-window. (The logs should be read from ‘receive_message’)
My main question is: why is the end-value [...]

Free devices: Modulating input with physics in Max4Live

Hi guys.
I’ve made a few M4L devices based on the physics objects. They take user input (from a 3D spatial controller such as the Leap Motion, Kinekt or similar) or automation.
I intend to sell these when they’re finished, but for the next few days I’m giving them away for free:

Launch plugin GUI with M4L?

Is there a way to open a VST’s GUI via M4L? I looked at the LOM but didn’t see anything–just want to be sure I’m not missing something. Thanks!


I am starting a Max/MSP project inspired by Christian Fennesz along with Tim Hecker, Alva Noto, and Pimmon. I am after other artists similar to them to look into, and suggestions on patches and ideas for patches for me to try.
I have created some generative patches that process input, but I am a little clueless [...]

Is edge~ only useful after a comparison?

I’m curious about why the [delta~] and [<~] are necessary before the [edge~] in the following example:


Shouldn’t one expect to get bangs from both edge~s?


I’m sure I’m missing something obvious but maximum~ doesn’t seem to do anything other than combine two signals. it does no choosing of maximum signal values. what am i missing?

Rotating vertices with poltocar

I have drawn simple square and want to know the x,y,z coordinates of each vertex as it rotates. I know that does not support matrix output, which would have helped me.
So I’m trying to rotate the square by moving the vertices manually instead of using glrotate. I’ve had limited success with poltocar, in rotating [...]

Controlling a stream of data from range finder

Hi there!
I am having trouble in controlling a data stream coming in from an ultrasonic range finder. I want to be able to use the range detected to scroll through MIDI scales in the air, i.e the moving further or closer goes up and down the scale. I have a piece of java script that [...]

Max suitable as VST host?

I am looking into the possibility of programming my personal VST host in max with custom midi routing for a huge orchestral template (filmmusic). But with my first tests I get the feeling max isn’t really as good as a VST host like Cubase or Vienna Ensemble. For instance: I loaded a Kontakt piano, no [...]

MIDI file problem

Hello all!
I’m hoping somebody can help me with something which has literally been driving me INSANE!
I’m trying to build a patch which writes midi files (for later import into a DAW). However, when I import the midi files, the tempo does not match with the expected tempo from the patch!
For example, in the patch attached, [...]

ddg.mono, first note priority request

Hello everyone,
I’m using ddg.mono in a project. Unfortunately it doesn’t have first note priority. I know most people prefer last note priority (so do I) but ascending scales with low note priority and descending scales with high note priority have a very nice portamento-like feel to it since you have to lift up each previous [...]

saving .axmd from within live – thispatcher seems to only work in max

here’s a simple example – when editing in max – clicking write saves the patch just fine. When you close and the patch goes back into Live, clicking write has no effect. Is the normal and is there another way to save the axmd file automatically from the patch itself (without having to [...]

i’ve build a max standalone on my windows 7 (bootcamp) in max 6.1, but when closing it (via file menu), it closes the windows, but leaves a running process (viewable in the task manager). this process [...]

Can I know my instance number in a poly~

Suppose I have multiple instances in a poly~ and each instance does something a little different. I’d like to be able to send information OUT of an instance for monitoring purposes and I’d like that information to be tagged with the instance number.
I haven’t noticed any way to query the instance number so I’m wondering [...]

Open CL anyone?

GLSL is parallel
OpenCl will be great for particles, flow, etc..
It would be great if someone could show an external embedding openCL

RGB to HSL conversion

Can anyone help me with this? I am looking to convert RGB values that will be typed in the Messages boxes to HSL values for the Color Swatch. I am looking to convert these values within my patch, I have tried some externals but I could not get them to work, like Jasch RGBtoHSL external.

Looking for a trance gate midi effect for Max for Live

I am looking for a midi effect for Max for Live which allows the creation of arbitrary trance patterns. Something like the one embedded in FM8, just to be clear. Many people implement trancegates on the audio output of some synth. This is not what I am interested in. I need something that is operating [...]

I just got the new Electronic Music and Sound Design Volume 2 and some of the examples use external objects vs.rand3~ and vs.dcblock~. I can’t find these mentioned in the book or online. Can someone point me in the right direction please?

I have acquired the depth data and color data from kinect by openni2. Firstly, i translate the depth coordinate system to world coordinate system. Secondly i use the function of convertDepthToColor() to acquire the coordinates of color data. Then i combine them by the point type PointXYZRGB. But the RGB pixels is not [...]
