Excuse me all, I am attempting to send MIDI between 2 MacBook Pros using the Audio MIDI Setup. There is a lag in communication between the two patches that are on each computer. I don't have ethernet cable availability. Is there any sure way to reduce the lag in regard to sending MIDI?  I might try a better network.

I'm not sure what kind of bug this is and I'm hip to blame Apple buuuuut
Export plugin has some wacky behavior. The AUv2 "effect" export validates in both Logic and Ableton but it doesn't appear on the plugin drop-down menu in Logic while simultaneously working fine in Ableton.
To be clear, the plugin shows up in the Logic plugin manager as "successfully validated" and has a nice blue check mark alluding to me being able to use it however, it doesn't appear in the plugin insert drop-down menu. Meanwhile, it works fine in Ableton

After some digging it seems perhaps the code is not properly signed to Logic's requirements to at a minimum to "run locally"
maybe
Ableton doesn't care

Yes, this is a "bump"
ANybody else having this issue?
AU plugin shows up as validated in Logic plugin manager but doesn't appear in plugin insertion drop-down list.
The AU works fine in Ableton.

Hey MANYSOUNDS,

Can you submit a bug ticket with a minimal patcher and steps that shows this problem? Please make sure to provide your system information:

Will do. Checking to be sure it isn't a stupid on my end first :P

Hey there, I'm trying to recreate cpole~ in gen~ but I don't have much of an understanding of how to translate formulas to max objects.  Any help would be much appreciated.

pure-data-cpole~-in-gen~

(since i feel you can't have it be a 'onepole' and have two separate coefficients(not that the number of coefficients matches the number of poles but, from what i've seen, a onepole only has one coefficient), so i was thinking it's just two 'onepole' filters applied separately to the real and imaginary? ..at least just going by the info in that cpole~ helpfile)

I´m trying to build a little events looper that would just record a few events on the press of a button and then play them back on loop when released. Looks like the best way would be using  Seq~ but I'm a bit confused as to how to tell phasor to only play a portion of the ramp as long as the length of the loop.

There was a great patch called aka.leapmotion. Unfortunately this doesn't work anymore - is there a new way of using the Leapmotion device ?

There was a great patch called aka.leapmotion.

Not exactly what you’re looking for, but MIMI Glover is how I get Leap data into Max.
https://mimugloves.com/glover/

Oh - I just realized, that Glover doesn't work with Monterey - well, I think, I have to wait for an update. 

Does anyone know if Glover is compatible with the Ultraleap 3Di? I've emailed Mimu a couple of times and no reply.

you could try this: https://maxforlive.com/library/device/4455/max-4-leap. It's still available for download.

Did anyone have any luck with ultraleap 3Di?

I tried https://maxforlive.com/library/device/4455/max-4-leap - but it says, that is it no more supported - or did I misunderstand something?

Hi everybody, 
Like many, I was looking for a new version of the Aka-leap object, for using the Leapmotion in max with the Monterey OS.  All the solutions suggested in the replies don't seem to work.
Thanks

Hi everyone!
I am not very experienced in Max, so any help is appreciated.

For a part of my PhD project I would like to do the following: I need to record data streams from the Kinect Azure sensor and store them in a file for offline synchronization with data streams from other sensors (recorded through their own software) and subsequent -offline- statistical analysis.

I am using the object dp.kinect3 to get the data streams from kinect to Max and I will need to record 4 numbers (x,y,z and orientation) from each of 6-7 skeleton joints, and will probably use the default sample rate for Kinect (30Hz).

Any thoughts on how to do this, or which objects you recommend as more suitable (i.e coll, mubu)?

Hi everyone!
I am not very experienced in Max, so any help is appreciated.

For a part of my PhD project I would like to do the following: ... 

seeking-advise-on-data-streams-recordingstorage

that other senors and sofware will probably dictate capturing form,
including timestamp format, in order to synchronise all sensor values
for analysis.
which max object and form is most suitable would also depend on amount
of captured data, or better say capturing length.
if all kinect sensors share same line, 30Hz make 120000 lines per hour.

unless you capture only when sensor values change.

For really long captures, I would rather use shell object
and write values directly into text file.
for example:
echo "timestamp values" >> ~/Desktop/021222_113325KinectLog.txt

which will insert line by line into text file on Desktop (space or tab separated)


Thank you all so much for your replies!
'Source Audio', the rest of the sensors will end up as .wav signal, which I will later transcribe to whatever format I get from Kinect/Max, I seem to be flexible there.

Kinect will be capturing continuously (not just when values change) and each experiment session should be about 30-40 minutes.
Any suggestions given these details?

Please post details about wished capture form, like if you need a time stamp on every line, if you want to put all sensors into same line or not,
if you want to separately capture each skeleton joints etc etc.

without that infos ... it is difficult to suggest something.

You can of course also capture values into buffer~ and save as wave files

I am sending the details which you suggested: 

Txt will be then fed to Matlab for processing

I can collect everything in one text line per sample. 

There will be one Kinect Azure sensor only.

Capturing will be continuous (not just when values change)

All joints captured together in one text line

 4 numbers per skeleton joint (x,y,z,orientation)

Timestamp needed only in first and last line 

I hope I am including everything needed for a more informed suggestion.
Really grateful for the help!




I forgot to ask about max or win, because that makes a difference
for writting directly to text file, which is very simple on Mac.

as first about timestamp:
max date object can not output sub second time format.
If that is needed, one would have to run per second triggered ms counter for that and form timestamp string - Date_Time (HH:MM:SS:sub)
if no subdivsions are needed, it would make things easier.
other option is to use timestamp when creating capture file.
In any case decision to collect data first into max text object and save a file
when finished is one option, to use shell object and feed input directly into text file a 2nd option.

The reason I thought about shell object in first place is that it is more secure, every entry will get written into text file,but in case of max text object, a crash would wipe everything collected so far.
------
now to the concrete examples :
here is first example capturing int max text object

I will post another one with shell object laer,  if you use Mac.






Wow! Thanks!
I will try that later tonight.

I run on Windows, so no need for Mac...
Really grateful!


Just finished with a bit of testing and it works! Thanks!
Can't figure out why the timestamps' differences (end-start) in seconds do not seem to correspond to the number of data lines divided by sampling rate (30), but I'll figure it out... 

I'll also try to implement the sub-second time stamp that you mentioned.

Btw, I switched the [metro 33,333] to [metro 30 hz] . Should be more precise, right?


Also, the [dp.kinect3] object help patches use the [qmetro], do you think that this could make the patch drop frames and affect the number of text lines? I need these to be fixed at 30 lines per second, in order to make subsequent synchronization with other data streams possible.

I have yet to test with the actual number of joints and orientation, but I am confident!

date outputs seconds only, so in theory you can be offset by max 29 messages from date output.
I don't know anything about that kinect object, but I would remove qmetro.
The idea in my patch is to first collect ALL values into a list,
and then output collected list using external metro - that 33.333 or 30 Hz as you prefer.
That also means that precise timestamp could differ from "real time" by 1 metro clock, or 33.333333333 ms.

I don't really know how to get that sub second timestamp using date object when triggered only once, because my idea was to poll date output all the time, not only Start and End.
Date also has ticks output, but that will give you time in ticks elapsed since system start, not absolute real time.



in fact on window cmd TIME can output seconds fraction

and also echo text to file works just as well as on Mac to write logs directly to a text file.

One can also use java, which I dislike ...
for example now mxj   could be reduced to needed timestamp

Here is max patch that does all using shell object

path for shell must have proper format, that's why regexp etc.


I even think  in last shell object in that respect, but this is 100% secure path form.  Name of text file can be also combined with time stamp etc, but that is your decision, how to name capture files.
Echo command creats file itself, no need to create it manually before capturing.
and path to shell object

https://github.com/jeremybernstein/shell/releases



That's great! Both are elegant solutions.
Sorry to say that still some assistance is needed...

In the first patch Capture Start timestamp in the file is not the correct. It seems to always be 4-5 sec after the Capture End timestamp of the previous capture session, even if these are hours apart from each other. Capture End timestamp seems to be correct...

I tried to run the second patch (after installing shell) but I cannot get it to create a file. If I understand correctly it is supposed to do this automatically, but I must be doing something wrong... I tried various tricks that I could think of, but haven't cracked it yet...

wrong capture start time is definitelly due to timing.
Date object should be triggered at loadbang
it needs few times to do so to update correctly.

here is fixed version, see reversed order
time, date


-----
Now to shell - can you post your file path,
how do you enter file path ?
And if there are any errors in the console ?
you can insert print at shell output to check for any errors.
Are there any restrictions to read / write on your PC ?

P.S.  I have to download that latest shell version and test it
I actually use older one from 2017, maybe there are some differences.

Even if you keep using text object for capture,
shell can at least help you get timestamp with sub - seconds
Not that it can't be done with js, but one has to install java runtime to use js in Max , and I do not do so on my PC
and in general avoid java because that forces users to also
install it.




Teams meeting recordings will be stored in OneDrive or SharePoint, depending on the type of meeting. Note that a recording will expire and be automatically deleted after a set period of time. The amount of time it's available is set by your admin, but you can change or remove the expiration date of any given recording. 

Now both options work!
Text fixed version you sent is working

Shell version did not want to write files in root or desktop, but gave no error messages (although I tested to see and directories with  no permission, or ones that did not exist gave error messages...) Anyway, a new folder on the root directory was a place where it is writing correctly.

Shell version was saving capturing time, but Only the fractions of the seconds. I added two more list items ($2 $3 and $3 $4 respectively) in capture End and Capture Start messages.

I have an Arduino with two sonic sensors and four potentiometers on breadboards. They all work as expected in the Arduino console but not in Max. Three of the potentiometers work and the fourth one on A0 does not. The data from both the sonic sensors looks like it is displayed in the same number box (box 5 in the patch)

I've setup the potentiometers on their own and they all work as expected in Max. Below is the max patch and Arduino code. 

Shout if I haven't given enough information about anything.

int distance = 0; // variable for the distance measurement
long duration01; // variable for the duration of sound wave travel
int distance01 = 0; // variable for the distance measurement

void setup() {
  pinMode(trigPin, OUTPUT); // Sets the trigPin as an OUTPUT
  pinMode(echoPin, INPUT); // Sets the echoPin as an INPUT

  pinMode(trigPin01, OUTPUT); // Sets the trigPin01 as an OUTPUT
  pinMode(echoPin01, INPUT); // Sets the echoPin01 as an INPUT
 
  Serial.begin(9600); // // Serial Communication is starting with 9600 of baudrate speed

}
void loop() {

  digitalWrite(trigPin, LOW);    // Clears the trigPin condition
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);   // Sets the trigPin HIGH (ACTIVE) for 10 microseconds
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  
  digitalWrite(trigPin01, LOW);    // Clears the trigPin condition
  delayMicroseconds(2);
  digitalWrite(trigPin01, HIGH);
  delayMicroseconds(10);   // Sets the trigPin HIGH (ACTIVE) for 10 microseconds
  digitalWrite(trigPin01, LOW);
  duration01 = pulseIn(echoPin01, HIGH);
  
  
  
  
  
  // Reads the echoPin, returns the sound wave travel time in microseconds
 
  
  // Calculating the distance
  distance = duration * 0.034 / 2; // Speed of sound wave divided by 2 (go and back)
  distance01 = duration01 * 0.034 / 2; // Speed of sound wave divided by 2 (go and back)
  
  
  // Displays the distance on the Serial Monitor

  for(int i = 0; i < 4; i++) {
    val[i] = analogRead(i);

    Serial.print(val[i]);
    Serial.print(" ");

}

  Serial.println(distance);
 
  Serial.println(distance01);
 
  Serial.println();
  
  delay(50); }

Hi,
I have an Arduino with two sonic sensors and four potentiometers on breadboards. 

max-not-receiving-data-from-arduino-correctly

to receive list of 6 values, only LAST one should be sent using
println.
this is the mistake:

it is visible in arduino serial monitor.
You get 6th value on separate line and then one more line inserted.

for(int i = 0; i < 4; i++) { val[i] = analogRead(i); Serial.print(val[i]);Serial.print(" ");}
Serial.print(distance); Serial.print(" ");
Serial.println(distance01);

Thanks for the speedy reply. So should it look like this? The first two readings are coming from the first potentiometer and the other 3 are ignored. I changed the number of inputs to 6


for(int i = 0; i < 6; i++) { val[i] = analogRead(i); Serial.print(val[i]);Serial.print(" "); {
    val[i] = analogRead(i);

    Serial.print(val[i]);
    Serial.print(" ");}
    Serial.print(distance); Serial.print(" ");
    Serial.println(distance01);
}
 
  Serial.println();

Sorry, it looks like its printing the reading from every potentiometer on its own line twice and then the sonic sensor readings.

Max not receiving data from Arduino correctly 

I made a simple synth patch that attempts to approximate the sound of a Chinese sheng. It works but after playing a few notes it seems like the ADSR inside the synth voices stops working properly. That makes me think there's a problem with how I've set up thispoly~ and/or the ADSR. As far as I can tell, though, I've set it up exactly the way I've seen it successfully done in other patches. So what am I missing? 

I'll add the patch as a comment...

I recently "discovered" the newish (as of max 8) xctlin object, which is a welcome change over manually parsing 14 bit CCs, and a more general solution than the "assign midi map" feature, so this is more of a PSA for others who might benefit from it because I didn't find much about it while researching the topic.

That said, I did find a weird bug where it doesn't respond to the first message arriving on a different channel after a standard 7 bit message is received.  More details in the attached patch.

14-bit-midi-xctlin

Interesting. I tested it quickly with another controller (other CC numbers and other channel numbers) and cannot reproduce. It's tough to send just one value with faders, so I added [print] and a counter to make sure I received the same amount of messages from xctlin and ctlin.
From what I see here, it's working. I will try again later if I can have more time.

Hi all,
I'm trying to copy some values retrieved from a buffer~ via function peek to a fixed size array in codebox. No matter the type of array (FixedSampleArray, FixedNumberArray, etc.), I get this message when compiling:

error:8050:50:assigning to 'RNBO::SampleValue' (aka 'double') from incompatible type 'array<RNBO::SampleValue, 2>' (aka 'array<double, 2>')

This also happen with FixedNumberArray, whose value , according to the RNBO reference guide, may change depending on the circumstances in which code is generated and used. 
I thought FixedNumberArray would have been a good choice to work with audio sample values regardless of their format, though I can't make it work. Help? 
Thanks in advance.

Hey Alessandro,
If you look at the documentation for peek: https://rnbo.cycling74.com/codebox/ref/peek
You'll notice that it returns 2 values. I believe there is some work to automatically select the first value if you do a simple assignment in this case, but that clearly isn't working right now you can solve your problem by adding a [0] after your peek() call to select the first item in the return.
