It's hard for me to ask you but due to inability to timely pay for my hosting services I need a free anchor in .com domain to build apps via Xcode. My current anchor com.compositorsoftware.XXX (where XXX is a software revision) will be discontinued soon. Can I use com.cycling74.XXX anchor for future revisions to build apps via Xcode?

The project grew to an extent where using distributed resources I was able to gain near zero latency in Logic using my RAD512 audio engine and RTZ524288 channel extension with Apple AirPods Max in 44100 Hz sampling frequency (without any dropouts). For this apps to work an anchor needed also.

I am following a tutorial on Youtube but it's PD and I am trying to recreate the patch in Max. What is the equivalent for the PD throw~ and catch~ objects?

Hi
I am following a tutorial on Youtube but it's PD and I am trying to recreate the patch in Max. 

trrow~-catch~-equivalent-in-max

send and receive. because non-MSP send and receive will also forward signal connections.

for the technical difference between send and send~ allow me that i  am pointing you to the forum search. 

i looked at the pd helpfiles for both and i suspect there are minor differences anyway.

if you need to rename the throw~, then you have to use [forward] in max.

if you stick to the send~/receive~ (with the tilde '~' symbol, similar to the original throw~, as this is the normal way to delineate between signal-handling and regular objects), you don't need to worry about using [forward], you can use the 'set' message like with other named contexts in max:


technically, aren"t tapin~ and tapout~ somewhat closer analogs to throw~ and catch~ ?

i could be wrong, but this article seems to imply they're more like send~/receive~:
https://hvc.berlin/Puredata/puredata-send-receive/ 
(maybe there's a delay introduced somehow we're not aware of, but it's true i'm not actually familiar with PD anymore, apologies in advance if i misunderstood)

(also, wasn't trying to contradict Roman 😅 
but felt maybe there might be a simpler answer to try first.)

send~... i first wrote that... but later changed my post to the non-MSP objects, because the pd helpfile confused me lots about the differences among the pd objects. :)

maybe the best advice is always to point out that there are mostly no 100% identical objects, which means that you have to make your own abstractions and check stuff carefully, message by message.


"technically, aren"t tapin~ and tapout~ somewhat closer analogs to throw~ and catch~ ?"

pd´s tapping buffer is delwrite~ i think. 

well, actually it is quite different, too.


I used send~ and receive~in the end. That worked. The PD tutorial also used delwrite and delread for a buffer which I replaced by tapin~amd tapout~

Throw~ /Catch~ equivalent in Max?

I've created a couple of helper objects for interacting with BLE and casting data from bytes. It would be great if there was anyone out there wanted to test these and flag any issues / suggestions on the repository.

Thanks for making this work.
I have no BLE unit at hand at the moment, but will definitely be interested

Is communication with midi BLE devices working ?

At the moment it is just polling of vanilla BLE devices. I saw Arduino BLE capable devices were becoming more popular, but the bluetooth examples haven't quite caught up. All the bluetooth examples I can find are Bluetooth 2.0 based and rely on a Serial RFCOMM interface, which just isn't how BLE works.

As a result, most students give up and move on to using OSC, which is fine. What I like about BLE though is the ad hoc / spontaneous nature of it. I like the idea that an audience member could come along to an installation and interact with it either via an Arduino BLE device or through some app on their phone. There is then an element of proximity involved which adds a nice restriction, but you can keep things entirely wireless. You also don't need a network infrastructure to send messages wirelessly. What you do need is something that will get the numbers from your, or your audience's, devices to where you want them to go (e.g. Max).

Is communication with midi BLE devices working ?

My understanding is that BLE MIDI is special case subset of the BLE standard.

From a macOS perspective you'd connect via:

Audio MIDI Setup -> Window -> Show MIDI Studio (⌘2) -> click Bluetooth icon (or ">>" menu -> Configure Devices -> Open Bluetooth Configuration)†

Then it should just appear as a normal midi devices.

Maybe a [`CABTMIDICentralViewController`](https://developer.apple.com/documentation/coreaudiokit/cabtmidicentralviewcontroller/) interface for Max may make the experience a little nicer.

For Windows, there doesn't seem to be as easy an interface with BLE MIDI. I'll need to grab a BLE MIDI and have a play around with the framework. My guess is that the connection is permanently kept alive or that it advertises with a 'notifying' property and push notifications are sent out††

What are current BLE MIDI device owner doing to connect with Max?

Byte cast - also very handy, would converting oposite way be an option ? float to bin for example ....

That's very doable. I assume casting float to it's raw bytes is handy for serial comms, but I believe that is taken care of within the object itself.

Mac and Midi BLE is no problem at all-
On windows, where restriction only one app at a time  apply to composite midi devices
it might be of an advantage to talk midi BLE, outside of Midi communication.
------
float to binary - simply  does not exist in max, I once had to help someone with a weird device
using float values sent as binary  using  sysex messages, had to roll js converter to achive it.

There is an extra example in the ref page to cover the new functionality.

I will need to try out the Arduino BLE MIDI library https://www.arduino.cc/reference/en/libraries/ble-midi/ and see what I can get working.

The numeric types in max (int, float) are always long, 64-bit (8-bytes). The float would be in double (long float) format. 





There would need to be some kind of flag added to the `b` mode to decide how the user wants the data to be interpreted.

Suggestions welcome: https://github.com/mhamilt/max-byte-cast/issues/new

or fire something on here and I'll flag it.

Some devices or at least some gadgets made with Arduino use single precision float
like for example buchla.com
They had external that converted float to 4 bytes array which then got sent as sysex via midi to program the Device.
I helped someone recreate that in Max because max external was outdated and undocumented.
Could not match the output till I realised that they used single precision floats.
sysex string using double float to sysex conversion crashed the synth.
---------
to byte-cast options 
I don't know if it would be too much to put that many conversions and options into single object, but if you offer 4 byte float input one should also have it as output option


I think you're right, this needs to be 2 objects to make it symmetrical, toBytes and fromBytes.

I can take the same source and just apply it to inlets instead of outlets. Shouldn't take too long to do.


Apologies, it  has taken me a bit of time to finally look in to this. 

In essence you can read data from a MIDI BLE device directly via the max-be object. This should mean you can bypass any restrictions on the Windows side. The way BLE MIDI works is by advertising a service  with UUID: 03B80E5A-EDE8-4B33-A751-6CE34EC4C700 that has a characteristic with a notifying property with UUID:  7772E5DB-3868-4112-A1A9-F2669D106BF3

This means you can just subscribe to the BLE MIDI characteristic directly.

Apologies that it is a bit messy, but this would translate to a patch, using max-ble, to roughly look like:


I will need to fully implement subscribing to characteristics on the Windows side, it works on macOS though.

I now realise I don't have a method to unsubscribe either, which is a bit of an oversight. I will look to implement that in the next week or so.

Hi! Very nice objects! I'm new to BLE, and I wonder if it's possible to send out data to the Arduino BLE with this object? More specifically, is there a way to do this example, but connecting with Max instead of a phone app? https://docs.arduino.cc/tutorials/nano-33-ble-sense/bluetooth 
Thanks!

If I implemented the  functionality you could 100% send data out. What I wasn’t sure of was what the “story” of sending data via ble would look like

if you fancy being a guinea pig, could you draw up a patch of what you would like the workflow to be and post it here? even better, include it as part of an issue on the git repository 

https://github.com/mhamilt/maxmsp-ble/issues 

I've added a comment to issue #14.  Initially I'd created a new issue for it, but then realized it was a duplicate... I closed the duplicate and added the comment to #14. Here is a small patch of an example of how it could be implemented in a patch.

Hi! 
max-ble is a very powerful and fascinating tool, I appreciate it very much. 

In your opinion, will there be a time for a max-ble extension available in RNBO? This would definetely change the rule of the game... 

From the RNBO thread and this thread I don't think the functionality to include max externals is quite there yet.

The BLE object is there to try and expose the bluetooth APIs for windows and macOS. Feeding that through a transcompiler like RNBO I can see getting messy quite quickly. 

Never say never, it isn't on the cards right now though.

Hi! For a generative music piece I am dealing with 64 changing datapoints (floats) that I want to map to filter frequencies.

I could for instance make 64 separate [reson~] bandpass filters, and adding the results together. However, that's a quite a manual and ugly approach, and not so flexible.

Are there any better ways to go about it?

We don't render RNBO UI objects in the JUCE (VST3/AU) plugins, we render sliders for parameters, which don't have a 'multi' equivalent.

I am finding often that I need to attach a [t b i] whenever I am patching. Is this a common pattern or is there something I might be missing. I attached an example I am running into. I am trying to cause output from [>] whenever either input changes.

I am finding often that I need to attach a [t b i] whenever I am patching. 

common-patterns-t

I tend to use [t] a lot, maybe the object I use the most. I find it useful to prevent any "bug" regarding execution order, and makes the patch easier to read if you go back to it after a while or send it to someone.
[t b i]/[t b f] and co. is indeed a very common pattern (at least in my patches) when you want a cold inlet behave as a hot one.

For a few operators (-, /, =, and their gen an jit versions), you can also invert inlets with a !. For example [!- 1] will subtract anything coming from the hot inlet from 1, while [- 1] does the opposite. Depending on your patch design, it might help you get rid of a few [t b i].

[t b i] is the most common way. 
[pak] is a more recent object, it allows less idiomatic Max programming. 
Using [pak] before a math object adds unnecessary computation/list handling. 
Use and abuse [t]. This is the way.

there is nothing wrong with t b i and his family.

[pak] is only cool until you want to set more inputs than having hot ones.

Common Patterns: [t]

I'm trying to pass json data from a MAXURL GET request to a js object. The js object receives the data the form of a message containing the function name and variable: $1. The js object handles the request perfectly but the text containing the parsable json data is truncated which throws an error on the JSON.parse() function.

 made in PD, into Max and I think I managed fairly well. However, I now have a persistent white noise and can't find what is wrong with my patch. The only thing I had to change from PD to Max was the highpass filter into the biquad object in Max. I also had to take a second delay out as it would create a feedback loop.

where-does-the-noise-in-my-patch-come-from

I don't see noise generated with your patch, but certainly saturation. Put some [meter~] objects to see what you're outputting: your signal is too hot (goes beyond -1/1), that's why I hear clipping saturation (which might be what you identified as noise?)

Turns out I had a helpfile open in the background that played as well which caused the 'white noise'. Regarding saturation: I have put my *~ values lower so now it sounds ok. With  delay~2 at the right side that feeds back into its own, I had to lower it substantially to avoid it clipping. Now I an going to try to make a more complex version. 

Where does the noise in my patch come from?

I need to do an acceleration from a Max for live device (since I did not find a way to do that in session view).

When I send a ramp through set tempo, I get glitches. I noticed I don't get these when automating in arrangement view. I also noticed I'm getting a glitch each time I change the tempo from M4L, smaller one when sending only one value at a time.

Does anyone know how to do that without glitches?

someone has some informations about the efficiency of gen (event domain gen, without ~) respect to js or native max objects? In particular, 

does gen has the same problem of low priority in the scheduler as like as js?

gen-vs-javascript-vs-max

Hi Mattebass, I don't know but I'm interested in hearing. You might be interested in trying out Scheme for Max, which allows you to do your code in S7 scheme-lisp and runs in the high priority thread (if triggered in the high priority thread), ie same threading as normal max and no auto-defer low like in JS I plan to add functions to control the threading better in upcoming releases too. Info here:  https://iainctduncan.github.io/scheme-for-max-docs/overview.html


someone here on the forums once said that javascript would be about 50 times slower than processing messages in max.


These sorts of things really depend on what you are doing, but in my benchmarks of some really simple operations (counting up to 1million and multiplying each count by a float), I only see about a 3 times speed decrease from plain max to JS.  This is with both running in the UI thread. Basically the same operation is 450ms in scheme, 500 in js, 175 in max (uzi, counter, *).  I haven't tested Gen though

FWIW I figured out how to test them running from the high priority thread, and this lowers the JS performance a bit, presumably from the deferred low call under the hood. But roughly the same. 

Thanks for the answers. In particular I was tying to figure out the usefulness of gen compared to javascript, and maybe the reason is based on gen's  better performance.  Moreover, I was trying to figure out what computational advantages could provide gen, because if gen~ works on a per-sample way, it's not clear how the as-fast-as-possible paradigm of regular max object could be improved by gen.
Anyone has some empirical knowledge about this?
Thanks again

I have not used Gen much, but in a nutshell, Gen code compiles down to C++ under the hood, so when you run it, it's running much like an external. So it should run much faster than JS (or scheme) as there is no interpreter overhead, especially for certain kinds of operations.

I’m curious for a more in-depth answer from someone at cycling ‘74 - when to use gen or gen~ or stick with javascript (or indeed use lua?).

That really depends on your end goal. For many situations, good old Max is extremely good.
gen~ is most useful when you want to process sounds sample per sample.
Javascript is appreciated in some situations but it is always executed in a low priority thread, so, if you are working with MIDI data, timed events, sequencers, etc, it is generally not that useful.
If you share your precise application, you might get more useful answers.

And of course if you're talking Jitter, it depends if you want the processing to happen on the CPU (gen may be useful in complement to Jitter objects) or GPU (shaders, etc.)

I should weigh in that if you are looking for what JS does but in the high priority thread, Scheme for Max does this.
