I would like to use Max' builtin midi mapper for this low-latency mixer I'm building. As far as I know the mapping always looks at all midi-devices. But I need a specific midi-device to be excluded (cause I have to alter its output).

I want to export some point clouds to a readable format (ie PCD), which implies encoding point colors into a single integer value, which is usually done with bit operators:

I was surprised to discover that it doesn't seem feasible at all in he jit paradigm, while it work as expected with lists, as shown in my example patch. What seem even weirder to me is that shifting ('>>' and '<<') and logical bitwise operators ('&' and '|') are listed in the jit.op help file but they doesn't seem to give expected result. The same operators are also not recognized in jit.gen.

So where is the error? Am I using [jit.<<] and [jit.|] the wrong way? Are they supposed to exis at all, given that they have no equivalent in gen?

Hi,
I want to export some point clouds to a readable format (ie PCD), which implies encoding point colors into a single integer value, which is usually done with bit operators:
rgb = (r << 16) | (g << 8) | b
and to convert back:
r = (rgb >> 16) & 255
g = (rgb >>8) & 255
b = rgb & 255

I was surprised to discover that it doesn't seem feasible at all in he jit paradigm, while it work as expected with lists, as shown in my example patch.

If you keep your matrice type as char, you only have 8 bits to operate the bit shifting within. So, you really can't do 8-bit bit shifting, or 16!
Use type long - showing here the coding part:

Yes! I just figured this out! I wasn't aware of (or forgot about?) the long type, so I tried to fake ints using float32 but obviously bitshifting didnt work. So I did a much slower workaround using / and % (see patch below). Your solution is obviously much more elegant, thanks!

However this doesn't explain why bitwise operators are not available in jit.gen. Is it because of implementation or hardware limitation, something like gen always working with floats internally regardless the input type?

I’d say it’s the latte, but shifting on floats is quite an unusual operation….

I can’t get rid of clicks when switching loops in RNBO. The crossfade in groove~ only works well for one loop, but when you switch loops you hear loud clicks . Max had a great grooveduck~ facility that solved the problem. Is there a similar object in RNBO?

clicks-when-switching-loops-in-groove~

You can open [grooveduck] and [grooveduck2] since they are just Max patches. You might want to rebuild that kind of system in rnbo~. It really depends on your application though, but you will in any case need to :
- fade out
- then switch loop
- then fade in
You might get more helpful tips if you share your patch making the clicks.

The fact is that I need to use loop switching inside rnbo, since the code needs to be exported.  Thanks for the suggestion, I've already started doing something similar.

I'm working on my first Max external, and I need to do some file I/O. Reading the Max SDK documentation on 

void myobject_doread(t_myobject *x, t_symbol *s)
{
    t_fourcc filetype = 'TEXT', outtype;
    short numtypes = 1;
    char filename[MAX_PATH_CHARS];
    short path;
 
    if (s == gensym("")) {      // if no argument supplied, ask for file
        if (open_dialog(filename, &path, &outtype, &filetype, 1))       // non-zero: user cancelled
            return;
    } else {
        strcpy(filename, s->s_name);    // must copy symbol before calling locatefile_extended
        if (locatefile_extended(filename, &path, &outtype, &filetype, 1)) { // non-zero: not found
            object_error(x, "%s: not found", s->s_name);
            return;
        }
    }
    // we have a file
    myobject_openfile(x, filename, path);
}

My C is rusty, but I know that strcpy can cause buffer overruns if the source string is longer than the destination array.

 has different advice: "use strncpy_zero() to copy the contents of a t_symbol to a character string first, as shown below:"

char filename[MAX_FILENAME_CHARS]; 
strncpy_zero(filename,str->s_name, MAX_FILENAME_CHARS); 
result = locatefile_extended(filename,&path,&type,typelist,1);

 is a bit vague: "Copy the contents of one string to another, in a manner safer than the standard strcpy() or strncpy(). This is the prefered function to use for this operation in Max."

In what way is it safer? From the name, I assume it guarantees that the destination string will be null terminated, which standard strncpy does not in the case where the source is longer than the specified size. But then how can I detect that case, which would result in an incorrect filename? The example code doesn't seem to handle it.

I'm working on my first Max external, and I need to do some file I/O. Reading the Max SDK documentation on file handling, I saw this example code:

The documentation for locatefile_extended has different advice: "use strncpy_zero() to copy the contents of a t_symbol to a character string first, as shown below:"

I recently made something like that: https://github.com/ersheff/simple-rnbo-web-template 
Feel free to use and/or offer suggestions.

No pressure of course, but I'd be interested in gaining a bit more insight into what parts were unclear or seemed too complex in the existing template in order to see if we can further simplify or split things up in a way that reduces the complexity and hurdle of getting started with the template or if an additional walk through / tutorial would be helpful.

Thanks again for sharing, appreciated!

Hello Florian,
it's the link between the index.html file and the js that is a bit obscure to me. But let's take it "as is", and skip the javascript question.

Simply adding a toggle button along with the sliders would be useful (the sliders shows a float range 0. to 1.  and not 0/1)

And, if I only have a single on/off interaction, is the resume() function the right way to play/stop?

For an even simpler bare minimum, an example with a single parameter that I directly assign to a html IU object would be useful for beginners, I think.

This template works great - bare minimum!

I added a parameter to the cycle~.
But this does not work??
I added param @name freq @min 20 @max 20000 @value 400 to RNBO (then export and replace files in "export" folder)

In the app.js I added getElementById=slider, parametersById = freq
In the html I added id="slider" + min, max, value etc


When I export and open in localhost, volume slider works, and if I change @value of the freq param to a different number (400 -> 45 or anything) this updates to the new freq. 
***But the frequency slider that I made doesn't do anything??
Can anyone see what is wrong in these screen shots??

(also, I tried using different names for the parameter in RNBO and the corresponding app.js and html-- nothing :(

Also... It would be great if there was a link to all the different UI input types available. (On c74 and Ableton sites they are using pictsliders).


Also, it would great to see an example of {outport} converted to an  html number box (or float) so I can see the numbers change on the website (for testing and cute aesthetics!)

Ok. This works.
Moving the "vol-slider" to control the frequency works on web page.
So something must be wrong when adding a second param and connecting everything in js and html.

Hi, Wil.
I updated the GitHub template to add a second slider to control the frequency.
Both frequency and volume sliders seem to work fine for me.
I don't see any specific errors in the code or patch that you posted, but maybe the updated repo will help identify the issue?

But which are the lines of code that connect the jsavascript UI object to the rnbo parameter?  Is it around here?

slider.addEventListener("pointerup", () => {
            isDraggingSlider = false;
            slider.value = param.value;
        });
        slider.addEventListener("input", () => {
            let value = Number.parseFloat(slider.value);
            param.value = value;
        });

polyphony-only-with-midi

Hello ADMANT,

What exactly do you mean with "without the MIDI feature"? do you want to control the voices manually without sending MIDI messages?
I that case you top level [rnbo~] object should be monophonic and inside you can place a polyphonic sub patcher with the @voicecontrol attribute set tu user: user

[p @title my-patcher @polyphony 6 @voicecontrol ]

using the [set target] and set [set mute] objects you can access/control the individual voices.

Is that what you are aiming for?


YES! Exactly.
The key is the simple vs user voice controller. 
Thank you sooo so much! 
Now I will take the complete tour here. Looking on how to manage the busy/free state of subpatches (I am used to poly~ object but totally new to rnbo).
Thanks again.

Still, I cannot get to the point. Is there a way to simulate the poly~ object behavior and the "note $1" message? 
In other words, my goal is to have the automatic voice allocation (send my values to the first voice that is not busy) without voice stealing (nothing happens if no free voices are available) and without using the midi objects. 
Do I have to do all the patching to manage the mute/target stuff by querying the busy/free map? That sounds complicated...
No other way? 

Attached is a simple example of what I am in.

Ok, ok, it was not soo so hard, it took me only a few days to find the way in the world of codebox. I created  an array with the busy/free voice status and the indexOf() function to set the target before sending out the values to the polyphonic subpatch. About the topic, simply I had to substitute the midiparse object with the listin.

polyphony only with MIDI?

I've been trying to load Magenta's DDSP-VST (https://magenta.tensorflow.org/ddsp-vst) into Max using vst~ and am running into some problems. Wondering if anyone can help.

When I promt vst~ with the "plug" message and find "DDSP SYNTH.vst3" and "DDSP EFFECT.vst3" in the file browser both are greyed out and are unable to be loaded. Max can not load them. All my other VSTs are able to be loaded with no problems.

I believe this is because both "DDSP SYNTH.vst3" and "DDSP EFFECT.vst3" are recognised as a "bundle" under file kind as opposed to a "VST plug-in".

Does anyone have any ideas? Greatly appreciate the help if anyone does.

Mac? Windows?
After installation, does the plugin appear in the list of plugins (left sidebar)? If yes, what happens when you drag & drop on a blank Max patch? Error message?
Does the plugin run fine in a daw (which one)?

Mac, apologies for not mentioning that in my first post. 

It does, yes, and after dragging it in I get the error message "no format AudioUnit exists". 

I've been using it in Logic and it's been working fine, no problems. 


isn´t that this message you only get when you have AU set as "preferred format" for the vst~ object?

i believe otherwise a corrupted vst or vst3 bundle would still load, no matter if on PPC, intel or M1.

using [rnbo.remote] to set enum params on the remote target, seemingly only works using the normalised value.

Is that a bug, or am I missing something?

Here's a patch to demonstrate my issue:

using [rnbo.remote] to set enum params on the remote target, seemingly only works using the normalised value.
Here's a patch to demonstrate ... 

setting-enum-params-with-rnbo-remote-bug-or-am-i-missing-something

If you attach a print after your [prepend input] objects you'll notice the one the works is using symbols. It looks like rnbo.remote only accepts symbols for enum parameters. I'll add a feature request to allow numeric indexing as well.

The reason "normalized" works in this case is because normalized parameters are numeric by design.

maybe my example wasn't clear:
Actually neither of the two versions (sending numeric value or a symbol) do work on the remote target (aka RasPi)
Only the normalised value changes the parameter on the Pi. If you open up the browser interface and observe the value changes there is't probably clearer.



Hey JAN,
I swear that the symbol version was working for me but I'll double check that.
I wonder, do the parameters change for you correctly when you use an attrui attached to rnbo.remote directly?


Thanks for double checking. I tried. various times with varios patches and the behavior was consistent.
for me it started to break with RNBO 1.0.2. Before it was working as expected.

 for changing with attrui: I will have to test that later tonight and let you know.

Hey Jan,
Sorry for the delay, this is indeed a bug, enum parameters aren't being updated with the correct osc types. I'll be submitting a fix and it'll go into the next release.

RNBO support is similar to the existing Gen support, but more streamlined, and uses the built-in
