Hello! I have one question. I am currently creating a particle system in jitter that runs on a GPU(jit.gl and glsl). I am applying a sprite image for each particle. My question is, how do I make a particle system that has multiple types of sprite images in Max?

For example, if there is a particle system with 1500 particles, can I make 500 of them in  a.png as a sprite image, another 500 in b.png as a sprite image, and the rest 500 in c.png?

Does anybody know of any methods, routines or externals that can convert hexadecimal bytes to decimal integers and back again?

I‘m wondering if [sprintf] can do this?

hex-to-dec-conversion-and-back

Thanks Roman. I thought that there should be a simple way to do it!

I did find an ancient package called Lobjects written by Peter Elsea in 2002 on maxobjects.com that does some conversions but much of the functionality in that (extensive) package is now incorporated into Max and the download site for the package and objects no longer exists. Pity because it does contain a number of other gems too!

Oh! Hang on, it's still available on his personal website - http://peterelsea.com/lobjects.html

and his original university repositry is still there too -
http://artsites.ucsc.edu/ems/ftp_files_ems/Lobjects/ 

He was obviously a very bright star in the earlier days of electronic music. His personal website contains a whole raft of useful tutorials on matters musica electronica!

It's perhaps of historical interest to note that in his technical reference to Lobjects, he's concerned about the then current limitations of only having computers with a maximum of 128Mb of RAM!!!

lobjects have been highlight of 3rd party externals for me over many years.
still, Romans suggestion to use sprintf is better in my eyes, one does not have to fiddle arround to remove "h" and there is no > 255 truncation limit,
compared to lhex.
for arbitrary list length, sprintf, iter and thresh would do the trick.


Thanks @SourceAudio. I'll add those ideas to my Sandbox file.
It's a bit of a shame that my attempts to hack in to my mixer's audio level service has come to dead end now, as even though I can extract the audio levels that I'm looking for in the UDP blobs it sends, there is currently no way that I can currently command the custom meter object in the software (Mixing Station) that I am using. 

Questions and advice about using the sprintf object go back a ways....

The sprintf object indexes every new message it receives, which results in ever-increasing memory usage as your patch runs. The somewhat recent advent of 64-bit memory addressing means that the memory usage is less of a problem. However, the above is still true.

For various reasons — efficiency is one of them — all symbols are cached in Max, and they are never freed unless you quit the Max application. Symbol-caching is a feature of Max that’s been around for a long time, and it’s been the recommendation of similar duration that we don’t suggest relying on patching/objects that generate tons of unique symbols. Even though 64-bit addressing does change things, I would still advise caution, depending on your sprintf usage.

(And it would be impolite to not pause at this point to thank our mutual friend E.J. for his clear explanation  of this to me a long time ago)

Thanks Gregory. I assume that if I were converting 2-nibble hex bytes, using the [iter]-[sprintf]-[thresh] method that @SourceAudio recommended, that would only generate a maximum of 256 symbols though? If the same values were to be presented to sprintf more than once, I pressume that the existing symbols would get re-used or over-written? Or would the longer hex lists themselves also create unique symbols? 

FWIW Jeremy updated the lobjects for Peter a few months back.
https://cycling74.com/forums/peter-elsea's-lobjects-macos-universal-x86_64-and-arm64

Yep. · If you convert an integer X to a symbol N times per second and the integer is X every time, Max will use that symbol from the symbol table (as um... a pointer to a string, I think).

that is one of the reasons why i only convert stuff bytewise. (the other reason is that i would not know how to do it for longer strings /greater values anyway. ) (and for midi, you dont really want to enter the whole string in decimal values anway, rather only controller or note  values.)

on my wonderful OS9 operating system RAM fragmentation is a real issue, far more than anywhere else. if you work with max, you should reboot twice a day, i.e. not only restart max from time to time.


but i also think that for 256 values you are on the safe side - and i would not be so sure if third party objects of the same functionality such as sprintf or buffer~ not maybe do exactly the same.

this test has now been running for a good while....


As you can see limit seems to be thresh with max 4095 items.
37074 x 9999 conversions int-hex-int have taken place
and in Activity Monitor Max gained as much memory :
fresh started without any patch:

--------
I guess any symbol manipulating tool in Max
like for example regexp will act similar.
If I understand it correctly, you need this conversion because
that mixer software sends meter readouts as sysex but
insted of midi sends hexadecimal represenation as plain text via UDP/OSC?


The Mixer sends the level signals out in an arbitrarily long blob on the end of a UDP/OSC style message. The header has non-standard OSC style addresses followed by a variable number of integer parameters including a blob length value. The blob tagged on the end is generally made up of 32 bit float  values for each level but without being able to decode the header first, you can not predict where the blob starts! There can also be anything from 4 to 96 such values in the blob depending on the message type, of which I'm only interested in two, that occur at varying positions depending on the message type! It's a nightmare to try to understand without breaking it all down into hex nibbles (x00 - xFF) that I can compare with the examples in the document I have. On top of that, the level decoding is not as simple as it sounds as it's neither a linear nor logarithmic scale - instead, the scale is formed from four linear bands that collectively appoximate to the desired logarithmic dB scale. It's more like a university level project than a hobby!

>>where do you get that limit of 256 ?

most things in midi fit into a single byte because they are 7 or 8 bits. 
and in most documentations everything is written with space between the bytes even if represents something "longer".

so i believe it is fine to start processing and displaying everything as single bytes - and when wrong decimal represenations of a 14 bit value appear you will notice and can still change the patch.

the original [Lhex] from 1997 is also not able to process more than 0-255 and will truncate 257 decimal to 01 hex.

to my understanding, when you limit yourself to single bytes, you will only create up to 256 strings in RAM - but for each instance. (which somehow recommends to use a coll with pregenerated values instead if you plan to have hundreds of copies?)

I'm running Max 8 on windows 10 and I can't seem to add an icon. When I go to build the executable, I click on include file, select the .ico file, then change the word include to appicon. But then when it builds there's no icon, and I get a message in the console that reads 

Other than that the build works fine. Does anyone have a solution to this?

https://cycling74.com/tutorials/advanced-max-standalones-part-4 

Hello, 
I have the same problem when I try to build the application with a given icon specified in a standalone object.
I tried the Visual Studio trick given in the tutorial, but I'm not able to open the .exe file with Visual Studio 2022. I'm on max 8.3. any idea of why it doesn't work like in the video ?


I finally found a quite similar solution with Resource Hacker by following this tutorial https://www.howtogeek.com/75983/stupid-geek-tricks-how-to-modify-the-icon-of-an-.exe-file/

confirming.. i can't make it work as well in visual studio 2022.  
Trying that go-around,

Only single icon group 1033 is needed in case you don't use own file formats which need custom icon as well.
In same go, one can adjust version infos etc

One can make standalone exe out of max runtime even without compiling it at all. Copy the exe file, rename it as your mxf, edit String Table to match the name as that makes it write proper named settings etc.

How do I add an icon to a standalone project on Windows 10?

I've built a synth, exported to .wasm, and scheduled a note on and note off event. All is well. 

However, let's say I want to cut all the of the notes currently active in my synth. I could send early note off events for active voices or build some custom functionality in RNBO to cut the notes off following a cut message in an inport. However, the original note off event is still scheduled and will happen.

This is leading to some odd behaviour - notes triggered after the cut event are being truncated, presumably because the original note off events are hanging around.

So, it'd be great if there was a way of either:
a) cancelling a specific midi event
b) cutting all active voices in such a way that the RNBO synth knew how to handle stale note off messages.

Hi all,
I've built a synth, exported to .wasm, and scheduled a note on and note off event. All is well.

Is it possible to cancel/invalidate an event?

Good evening all.
I'm creating synths for a web application, so building them in RNBO then exporting them to web assembly.

I've created a simple synth in RNBO and configured it to have 16 voice polyphony. I've also exposed the voice parameters which allows me to target individual voices using a path, such as:
poly/<id>/<param>

Using the attriui object, I can see all of the individual voice parameters formatted in this way. When I export to web assembly,  logging out the individual parameters also confirms to me that these individual voice parameters exist:

console.log(device.parametersById.get('poly/16/amp'))

However, when I trigger notes using a MidiEvent, I can't see any way of knowing what voice I am triggering, so I'm unable to effectively target the individual parameters. What I would really like to be able to do is something like:

- Query the device to get the next available voice id
- Target the voice, setting the desired parameters
- Schedule an event for that voice

The other option would be that I export a monophonic synth and, in JS, create a new synth instance for each note event, then dispose of it after it has finished. Not sure on the performance overhead of spinning up so many audio worklets, but as a concept, does anyone know if this is possible? Can I dispose of devices?


Many thanks in advance for everyone's time.

Cephas.

I have some mc.cycle~ objects that each have many many sine tones. At any one time, I want to be able to select a few of the tones within one of the mc.cycle~s and manually fade them in/out with a single slider mapped to a fader on a midi controller.

I'm having trouble finding a way to do this kind of dynamic mapping. Controlling a single voice, or all the voices, is doable. And I can "fade" them in one at a time with mouse clicks on a multislider, or many at once with messages through an mc.target object. But not sure how to choose just a few that will then respond to a single slider object.

I am trying to write a standalone app called Nudger for somebody in a different country whose setup I have no details for and who does not have Max or enough tech knowledge to play with it. It's a very simple tool that converts control message coming from one port into note messages sent to another port and all unmodified message to a third port that can then be used in Cubase to control various jog wheel functions from an X-Touch controller. All that works fine.

In order to ensure that the MIDI configuration matches his system, I have provided picker lists to ensure that the MIDI messages are being read from and then sent to the correct ports. Again, all that works fine.

However, in order to save him having to re-enter the configuration every time he uses the app, I am trying to store the three port configurations using a coll with a read process to load the coll data when the app starts and to write the coll everytime the port selctions are changed. Again, that works in the patcher but not in the standalone!

1) I assumed that the executable (the Nudger.exe file) would operate entirely on its own but I am now concluding that I need to include the collective (the Nudger.mxf) and its resource folder when I send it to him. Is that correct or not?

2) No matter what I try, the executable is reading the configuration file (Ports.txt) into the coll from the resource/support folder but when I write the data back, it always goes to another copy of the Ports.txt folder in the same directory as the executable. How can I resolve this such that the executable uses the same file for both reading and writing?

3) Is it not possible to embed the coll and its data in the patch so that it doesn't need to be read from a file at all? Again, this works in the patcher but not in the standalone.

In the attached patch, I have put a red box to indicate the bit of code that has the problem.

Urgent assistance with this would be greatly appreciated!

Help!!!!

urgent-help-needed!-stadalone-search-paths

the 100 % solution is to use absolute path to Ports.txt file.

you use path message to this patcher to use that as path while editing in max,but
 ;
max senapppath message to get path to standalone exe file.
Assuming that you want it to read/write next to patch or exe file.

Give me a minute, I'll post a patch demonstrating that,
there were many posts here dealing with same thing.



sorry, I was too short in reading and missed your other questions.

Standalone that you send must be complete.
Means folder with exe file +  mxf + all resources .
in some cases one has to copy vb runtime dlls into it.


If midi configuration always remains unchanged,
you can simply loadbang port messages to midi objects,
needs no coll at all.
By the way, embedded coll is stored into mxf same as in the patch, but unchangeable, once compiled into mxf.

As it takes some time to load all ports, depending what else is running on app start, I would add some delay before reading Ports.txt file.


I am sure you remember that one can set midiport as exclusive
for midi I/O objects


this is what I would enter in standalone inspector

Thanks and thanks again @SourceAudio. There's a lot to digest there but I'm hopeful that your ideas will work.

Yes, I realise now that the standalone .exe file is simply the Max Runtime module and that the actual code comes from the .mxf file and the resouce folder. Not ideal when you want to send just one file to do all the work but, hey ho! I'm wondering if there is tool that creates a truely standalone, compiled and linked executable from Max code in a single file, like I was used to in my Fortran/Pascal days?
I get what you are saying about embedded colls - it was what I suspected, thus having to read and write the config to something external.
I have no idea what MIDI ports he has in his sytem and I can't assume they won't change. Hence why I went for the picker lists and an initialisation sequence that ensures all the Max midi ports are disabled before I start (bottom left in my patch).
I have put some delays in at the initialisation stage to try to see if that fixed the problem but it didn't make any difference.
The whole thing only runs through a single presentation window that shows the port configuration menus. The code that actually does the task of converting and separating the MIDI messages is tiny (bottom right of my patch).
Anyway, I will have a look at your suggestion and see if I can get that to work now.

@SourceAudio - thanks again. I can see what your patch is doing - except, what is the symout argument in the sprintf command - I've not come across that one before?


Hi Andy,
yes it is possible to make a single exe file, but not from max itself.

I use enigmavb exe packer, which is freeware, to do so.
I am not at home, have only mac with me, so can't upload any windows resources.
It is a very simple procedure, most work actually is to trim standalone down to include all needed files, but nothing else, to reduce the size.

When I come back home in few days, I'll be able to upload or send any infos needed. 
----------
About disabling midi ports till correct ones are selected ... ?
Correct ports are the ones your user has to select in popup menu,
and then store them into coll.
On loadbang, it is enough to keep gates to all midi ports closed, till
coll dump with all stored ports finds corresponding symbol(s) in the menu,
which then opens the gate upon setting the port.
Manual selection in menu also opens the gate,
route menu symbol output to t 1 s   trigger 1 (for gate) symbol for port









Your idea works perfectly thanks!
I'll have a look at enigmavb - it looks interesting.
The problem with Windows is that not all MIDI drivers are multi-client - in fact very few are in my experience. It means that if Max is sitting on them then other apps can't connect to them. It's a real pain sometimes. As I'm not able to see what happens at his end, I'm having to cover all bases and make sure that Max doesn't inadvertantly stamp on his system, hence the decision to ensure that Max diables its own access to all the MIDI ports and then only activate the ones he chooses to use. In fact, thinking about it, I ought to disable any previously selected port when the picker list changes!

glad it worked, at least the part with path etc I guess.
Windows limitations with midi and audio drivers use between applications  is really a  big problem.
I am not sure if disabling midi ports in Max does free them for other applications, never tested that being Mac user ...

I will post some settings of enigmavb as soon as I come back.




symout in sprintf outputs string as symbol, in case there are any spaces.
Same as inserting tosymbol at output.
----


Disabling all but selected midi out ports might get tricky
because you use 2 output menu objects.
One could loadbang - disable all, then read coll for saved ports,
enable them if matching ports are found in the menus.
Manual selection for input - no problem


But you can't do it same way for 2 output ports.
I would suggest to select all midi ports and execute all using button
which would set ports and store Ports.txt file.



It's Ok, I have that covered. On startup, a loadbang disables all the ports in Max and then when the config is read into the coll it enables those ports it finds. As the config file only ever contains the names of ports that are listed in Max at the time they are chosen, it is unlikely to fail. In the event that a port is removed or the name changed externally, Max will simply select the first port in the list by default. I suppose I could be clever and compare the name in the config file and the name in picker and if they don't match, colour the picker red to indicate that it needs a new selection.

I've been using Max for a few years now, and sometimes I want to be able to weed out zeros (0.) I had a sudden realization today that an easy way to do it is with sel, and the second outlet. Maybe this is common knowledge for many people, but I didn't see anything on a quick search of the forum!
