I'm trying to learn how to make a plugin from a gen~ patcher using the Gen~ Plugin Export package. I'm simply using the GenPluginExport.maxpat and following the instructions. But I'm blocked at the CMake stage. I'm hoping someone can help me.

I'm running a 2019 MacBook Pro with MacOS 11.6 Big Sur and Max 8.2.1.

I have installed CMake (3.22.0) and Xcode (13.1). I can open both programs with no problem.

I export the code in the Max patch and this seems to work.

In the Terminal, I can change to the gen~ Plugin Export/misc/build directory.

But when I enter "cmake .." I always receive this not very encouraging reply:

I have tried various things (rebooting, moving CMake to different directories, etc.) but to no avail.

I have only limited experience with the Terminal, so perhaps I'm missing something obvious...

But when I enter "cmake .." I always receive this not very encouraging reply:
	zsh: command not found: cmake

Hi,
I'm trying to learn how to make a plugin from a gen~ patcher using the Gen~ Plugin Export package. I'm simply using the GenPluginExport.

It sounds like CMake isn't on your system's path. That means you'll have to give the full filepath to CMake when running "cmake .."

So for example, you can run the following from the build directory:
/the/full/path/to/cmake ..

where you substitute in the entire path to CMake.

Thanks for your quick and clear reply. I presumed it was something simple and obvious like this. 

Unfortunately, however, I must still be doing something wrong. When I type in what I think is the complete path, I get the same result: "no such file or directory." I have tried moving CMake to different directories, pointing the Terminal to the same directory that CMake is in, etc., but nothing works.

What am I missing? Sorry for my ignorance - and thanks for your help!

/bthigpen/Alpha1000/Applications/CMake.app/Contents/bin/cmake ..

if you're using the Cmake gui app, you can add it to your path by opening Tools -> How to install for command line use and following the instructions


I followed both suggestions. Isabel's, strangely, did not work. But Rob's did!  :)

However, I am now blocked at the next step. "cmake --build --config Release ." returns "Unknown argument Release".  None of the variations I tried worked either. What am I doing wrong here?

Thanks again for your help and suggestions!

PS. Looking in my build folder, where the final build will (eventually) be found, I see that it is empty: no folders "C74GenPlugin_artefacts/Release". Is this normal?

Thanks for your patience, Ben! 

You can try this instead:
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

(You might need to delete and recreate your build folder if you get errors from the above.)

Alternatively, you can just build a debug version with
cmake --build .

There were warnings about 2 deprecated commands (getNumInputChannels and getNumOutputChannels), but the build worked, the plugin opens in Reaper and functions correctly. 

Thanks for taking it for a spin, too (it'll help as I'm cleaning up the documentation and some helper patch tools ;D).

In that case, it might be useful for you to know that for me (on Macintosh, with the configuration listed above) the change directory command for Macintosh in the GenPluginExport.maxpat did not work. But the command on GitHub, which is the same as the one for Windows in the patch, did.

My students will soon be trying this on Windows machines, so I or they may be back with more questions ;)

Going thru this with a student right now, on a PC running Windows 10.

We have successfully installed the Gen Plugin Export package, CMake and Visual Studio.

In the terminal, we can change directory using the command listed for Macintosh, but not the one for Windows. (This is the one that works:
   cd "~/Documents/Max 8/Packages/gen~ Plugin Export/misc/build"
I think they may be reversed in the GenPluginExport.maxpat, since for me, on Macintosh, it was the other one that worked.)

Then, unfortunately, typing "cmake .. " or "cmake -DCMAKE_BUILD_TYPE=Release .." returns

CMake Error at CMakeLists.txt:20 (project):
  Running

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
See also "C:/Users/Sim/Documents/Max 8/Packages/gen~ Plugin Export/misc/build/CMakeFiles/CMakeOutput.log".

 The key line here "Le fichier spécifié est introuvable" translates : "The specified file is unfindable." However, CMake itself seems to be findable, since typing cmake (with no dots) gives

 cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>
  cmake [options] -S <path-to-source> -B <path-to-build>

Specify a source directory to (re-)generate a build system for it in the
current working directory.  Specify an existing build directory to
re-generate its build system.

Run 'cmake --help' for more information.

Any suggestions for the Windows world?

It looks like the default build system that CMake is configuring is nmake which might be causing some problems. We can try specifying that we want to use Visual Studio instead of nmake.

If you have Visual Studio 2019 installed, you can try this command:
cmake -G "Visual Studio 2019 16" -DCMAKE_BUILD_TYPE=Release ..

In theory, the following should work for Visual Studio 2022, but I have not tested VS 2022 yet and am not sure what might break with the new version. :)
cmake -G "Visual Studio 2022 17" -DCMAKE_BUILD_TYPE=Release ..

We have installed Visual Studio 2022, so we tried that command. Here is the result:

Just in case, we tried "Visual Studio 17 2022" but that didn't work either...

Ah yes, you're right it should have been "Visual Studio 17 2022".

Can you try without the release type specification? 
cmake -G "Visual Studio 17 2022" ..

"could not find any instance of Visual Studio"

I did some Googling around, and a few things you might try:

- in the Visual Studio installer, make sure the Visual C++ tools for CMake is checked and installed
- reboot the machine

Ok, thanks. We're looking for this now. 
(There were dozens of options in the installer and we went for the minimal set.)

Hmm, we installed C++ Tools for CMake end rebooted. 
But - "No CMAKE_C_COMPILER could be found."

Hmmmm that's interesting. I wonder why it's not finding the MS compiler... Just to check, are you able to open Visual Studio?

One shot in the dark is to reinstall CMake so that it's been installed after Visual Studio. Another thing to try is to try the command from the "Visual Studio Developer Command Prompt". Both of these ideas would be to see if it helps CMake find the compiler.

If that fails, can you attach the CMakeError.log as an attachment here as well as the output from PowerShell when running
$env:path -split ";"

Yes, we can open Visual Studio. Although we didn't try again after installing the Visual C++ Tools.

I'll pass your suggestions on to my student (or he'll read them here). Hopefully, he'll be able to try them and come back with some results. Otherwise... we'll keep working on this in February!  We take long vacations here in Belgium ;)

I'm glad this was easier on Macintosh :) I'll see if I can build a few useful plugins now!

Thanks again for your help!

All the best,
Ben

I encountered this behavior and thought I'd post it here. I have a jit.pwindow that is rendering some jit.gl.gridshapes. Then I put the whole assembly in into a bpatcher.

Now I want to give my user the option to run the whole patch in fullscreen or windowed mode. But when I toggle fullscreen, my pwindow inside a bpatcher breaks.

If the pwindow is in the top level patch it survives the transition to fullscreen just fine.

It looks like an easy workaround for my case will be to get screen size and then set the window size to the screensize. But I thought it might be useful to mention this. Max is great! Thank you. :)

i am using custom fullscreen only, for a number of reasons.

but did you try to  "; max refresh" the situation  yet?


I went ahead and built my alternative this afternoon, which is working like a charm.

But for the fun of it, I just tried "; max refresh" but that didn't seem to help.


hell, it doesnt even comes back when you leave fullscreen.

p.s.: but it also happens the other way round. if you paste the patch in a fullscreenwindow it works, then stops to work if you go out.


hi Joe, can you provide OS, Max version, gl engine, and GPU specs?

Your initial patch works fine for me on Mac-tel

Hi! This is my first question in the forum, i ll do my best to be clear!

I have an mpc1000 and i want to extract the bpm of a sequence into max using DIN midi.

Maybe there is an easier way but as far as I know by using the "rtin" object i can get the clock beats after routing number 248. How can i convert the clock beats into bpm?

I think *set current_song_time' works only after playback is started.

I make a research in the forum and for this I already test sending before the playback command and after the current_song_time but often, the first time after I change current_song_time value, the play start from the Play Start indicator...
More suggestion?

I email to the support and the reply was:
" There currently isn't a way to use the LOM to start playing at a specific spot in the arrangement view. There is a feature request open for this at Ableton, but I can't say if or when it will be implemented. "
May be it's useful to someone.
I use the cuePoint as workaround for the problem.

I know this is an old thread and a relatively unsupported object at this point, but I'm wondering if anyone has had any luck with csound~ in Max 8? 

I'm on Mac OS 11.6 running Max 8.2.1 with csound~ v1.1.3 and I'm still getting the error 'could not load due to incorrect architecture.' so it seems like it's still not playing well with 64-bit. Any suggestions or thoughts are appreciated!

I've used it on OS10 64 bit with Max 8.1.X with no issues, but not on 11 or Max 8.2.1. 

I am actually in the process of porting Victor Lazzarini's Csound 6 object for Pd to Max to replace the old csound object, so I will be making sure it works on new Macs/Max and eventually M1, but I will probably not get it done until sometime in Jan or Feb as it's a side project to my main thesis work.

Excellent iain, very glad to hear that—I will certainly be keeping an eye out. Appreciate the prompt response as well!

I'm working on a sensor project with Arduino for school and would like my output to be sounds from Max when it receives a 1 or 0 from Arduino. I'm a complete beginner, just exploring possibilities , and wondered if you could help with this option - playing random notes / short melodies through my midi keyboard (has onboard speakers). So far I'll get one note through and it stays for a long time, changing to another note unexpectedly. I realise there's a lot I need to learn, would appreciate any guidance! Thank you.

That did the trick, thank you. Would you mind one other question, related to the other ways I'm trying to output sound?  With playlist, is there a way to make the full track play without retriggering? (currently every time the sensor sends a 1 it starts the track over). 

For that you issue playing state and disable receiving of sensor
messages till track stops playing.
but if track plays in loop mode ... that's more a logic question, and not how to do it.


Hi, thanks very much for your reply. I wasn't able to figure it out disabling receivng of sensor messages in Max, but nevermind for now since my deadline is coming up , the delay in Arduino helps! But I have a big problem now - for some reason, the random note generator does not turn off and goes on until it seems to hit an infinite loop, and I have to shut down. I used the makenote and clear msg but it seems to have no effect. Also switched up my sensors to test, and indeed whenever the random note patch is attached to a sensor, it gets stuck on 1.  Would you kindly have a look at my patch, if there's something I've done wrong? 


I just realised the pgmout might have something to do with it, as when both random generators are running it puts it into forever mode - it'd be great to understand why and how to avoid this problem! Thank you. 

I want to see Arduino code to be able to see what is going on.
Maybe it is simply badly programmed and sends data too often.
Remove that port z and port b.
If you want to close the serial port in Max, use close message.
But that is needed only if another app needs to use that serial port, like
Arduino IDE to upload the code.

Then ...
You should not send pg change simply like that, as it might cause hanging notes.
You understand what I mean with that ?
Not all synths are set to turn all notes off if they receive program change message.

You use 2 makenote objects, which can cause problems if they talk to same midi
device on same midi channel.


Playlist has this playback notifications  outlet.
This is not perfect solution, as it won't work if pause is used or
playback loops.
But for your simple case it would do.


Thank you so much! 
I changed the midi channel to match on the makenote/noteout and pgmout, and also saw it worked when I changed to different devices. I liked the effect of the random midi programme change but I can see it's not ideal... when I have time to do something more musical I won't have to resort to random things.
Playback notifications outlet - thanks for showing me how this works with your patch, really helpful and it works great.
I've left the Arduino code from Adafruit MPR121 almost as is except the print statements to send 0's and 1's.  I will get some help with this part when I go to school today. Really appreciate, I don't really understand what I'm doing yet so it feels great to learn these small details :)

I see,  adafruit touch sensor.
You say :
I've left the Arduino code from Adafruit MPR121 almost as is except the print statements to send 0's and 1's.


Serial.print(i); Serial.println(" touched");}
Serial.print(i); Serial.println(" released");}
with 
Serial.print(i); Serial.println(" 1");}
Serial.print(i); Serial.println(" 0");}
which would come out as list 
0 1   or 0 0 in Max for 1st Sensor Pin, 1 1 and 1 0 for 2nd etc
(*** touch pins are numbered from zero up.)


But that is not implemened in your Max patch.
You need to distinguish between touch and release and also which
pin is touched/released, otherwise you will double trigger.
If all you want is to detect touch and ignore release
remove this part in Arduino code: (or comment it out)
if (!(currtouched & _BV(i)) && (lasttouched & _BV(i)) ) {
Serial.print(i); Serial.println(" released");}---------------------
If you want to keep both, then in Max you need to do something like this

*** Replaced that example, Adafruit numbers pins from zero


But without knowing the Arduino Code exactly,
it is just a guess.



Wow, thank you for continuing to follow up, it's encouraging. That's right, as you said, this is what I have:

 for (uint8_t i=0; i<12; i++) {
    // it if *is* touched and *wasnt* touched before, alert!
    if ((currtouched & _BV(i)) && !(lasttouched & _BV(i)) ) {
      Serial.print(i); 
      Serial.print(" ");
      Serial.print(1); 
      Serial.println(" ");
      //Serial.print(i); Serial.println(" touched");
    }
     //if it *was* touched and now *isnt*, alert!
    if (!(currtouched & _BV(i)) && (lasttouched & _BV(i)) ) {
      Serial.print(i); 
      Serial.print(" ");
      Serial.print(0);
      Serial.println(" ");
      //Serial.print(i); Serial.println(" released");
    }
  }

The number boxes attached to unpack show me sensor number and whether it's touched/released, I thought? The retriggering is the issue though? Sorry that I'm not quite understanding. I haven't had a chance to play with only touch, but thanks  - it's something I should think about.

you need to send only pin number, space and state including linefeed (println)
Serial.print(i); 
Serial.print(" ");       
Serial.println(1);   ( or zero for released )

Problem is in max patch.
You receive a list with pin AND state, for both touch AND release.
Did you look at patch I posted ?

You have to understad what max objects do.
Sel 1 2 3 4 5 etc will output a bang if it receives matched number.
That bang sent to toggle will change the toggle state.

You receive for example 5 1 from sensor = pin 5 touched

sel object sends a bang from outlet which matches 5 to toggle.
If toggle was off it will turn on = starts metro.
When pin 5 gets released it sends 5 0
AGAIN sel 1 2 3 4 5 ...
will bang and change toggle state to off .
You don't want that.
----------
You have 2 options
1 remove sending of release state from arduino
or
2 use stuff in my patch to bang only on touched input.

I can not explain that in simpler words.


AND remove that clear from makenote,
use stop if you need to clear hanging notes.
clear message does the oposite - prevents makenote to turn notes off,
and so they hang !!!! 


P.S.    if you want to control toggle with both touch and release,
than use the left example I posted - metro will run only while pin is touched, 
and stop when released.


Amazing, thank you, very kind to explain that explicitly for me. I had wondered what the difference between clear and stop was too - I didn't understand what the documentation meant by cancel future note-offs, so I get it now!
I want to control with both touch and release so will use the left example you posted ! 
Thank you so much!



Just wanted to say, the next day the pin finally dropped I adapted your example on the right for use. Lists, how to use the if statement and  zl change, got it now. Thank you again. 

Random notes in Max through Midi keyboard using noteout

R_Gol

I'm using the object zl.lookup to choose a frequency from an array of 127 frequencies by using a midi keyboard to choose which frequency to play. Each key is extract different frequency number.

I would like to have the option to play only on the white keys and still get numbers that are follows each other.

If I press middle C I get the number 60 and if I pressed the following key C sharp I'll get 61, for D I'll get 62 etc etc

I would like to have the option to get following numbers (60,61,62,63... ) for pressing only the white keys.

by mapping the keys once more. 

you can use the usual math to contruct diatonic scales, but it is probably better to use a simple list.

use this to generate, then use coll (or zl nth / zl lookup)

center is 60.

Thanks for your replay.
How can I open the code you shared in max?

With this old style max patches you select everything including / between
max v2
...
...
#P pop;
copy, and in max paste or new from clipboard.
----------
If you want to use only white keys, filter out black ones using zl filter.
That would let you use remaining 75 white keys.
Then use white key numbers to recall any frequency you assign it to.
For examle using coll

0, 222, ;
2. 333,12345;
etc

or to map any midi note number to white keys, whatever


Can you show an example? I can't wrap my head around it

My list of frequency is fixed. I want to access each index of that list using only the white keys. So my white keys should be following numbers 60,61,62,63,64 etc to access each of the 127 frequencies  instead of 60,62,64,65,67 etc 

How can you access 127 frequencies using only 75 white keys ?
And that 75 white  keys would remain on hypothetical 128 key keyboard.


Yes, you are right. I can't access all those frequencies. I might anyway use only the middle range of the list (between 30 to 105)

If we are talking about midi keyboards and white keys it is clear
what is intended for playing the frequencies.
In max one can make kslider with hundreds of keys, but then why
keys and notes ? And not some sort of buttons ?
Anyway, it is easy to use only white keys, you can also transpose the range
of the incoming notes from keyboard to reach other freq. list items.
