thanks for sharing! I watched the Vimeo demonstration, very cool. I tried install it but unfortunately tof & maxlib do not have apple silicon builds... but i'm looking through the individual files and getting a rough idea of it... is there any documentation that could help me better understand the project?

No, it is a very old project (almost 15 years old). I am sure you know about it but a good project to look at is: https://github.com/porres/pd-else

@bklindgren I have strictly used mtl abstraction to build some custom instruments running on Pure Data.

Nice instrument!
Just pasting the youtube embed here:

How about this one. My favorite so far!

not my project, just sharing

@jamcultur You need to adjust the audio buffer, for example using 512 (this will add latency in the signal, but maybe you don't care if you don't use [adc~] -> [dac~].

@flextUSer Neat! I see that you are using netreceive so it is really a standalone app? You could use OSC and make it a bit more compatible with other applications IMHO.

Also I am sure you are aware, but share for people searching for sequencer, trigger, timeline etc https://www.iannix.org/en/whatisiannix/

Do you have screenshot or demo of your external - patches in action?

I find [Black MIDI / Art MIDI] videos quite interesting:

I don’t have much time to dive deeper, but I took a moment to create a Pure Data (Pd) patch that sends MPE MIDI to a VST that supports it (Strike, Glide, Slide, Press, Lift – sometimes called 5D). It’s not exactly a Black MIDI MPE setup, but I’d love to see someone create a patch that truly showcases this concept...

⚠️ Warning: Contains flashing lights:

Patch (only using 1 note on channel 2)

mpe.pd

Crazy stuff. Keep up posting those please.

Another alternative is to use patreon, a good example:

@porres Let's go! Looking forward to test this! Thank you sir.

Well, silly me, we have the Audio I/O Error shown in the main interface! I think this is a good indicator that PD wasn't able to process the DSP fast enough. Sadly I don't think we can log that or get the information in a patch to count the number of occurence...

Checking the source, I see this commented code, would love to have this information in the patch, or at the very minimum in the console log:

if (sys_getrealtime() > nt_nextreporttime)
    {
        post("%d audio I/O error%s", nt_errorcount,
            (nt_errorcount > 1 ? "s" : ""));
        if (nt_resynccount) post("DAC/ADC sync error");
        nt_errorcount = nt_resynccount = 0;
        nt_nextreporttime = sys_getrealtime() - 5;
    }

Thank you, I am new to Windows, trying to fine-tune the OS as much as possible to get super low latency (under 5ms). In linux when using qJackctl, on the main window, there's an "XRuns" counter that increments each time a dropout occurs.

The number in parentheses shows the number of overrun xruns. Overruns occur when the audio buffer is not consumed quickly enough by the system, leading to a buffer overflow.

The number outside the parentheses shows the total number of underrun xruns. Underruns happen when the system fails to provide data to the buffer in time, causing a buffer underflow.

This is what I am looking for to have in Windows or directly in PD.

@porres Trying your library for the first time, I know late to the party! Is there a limiter~, the one from zexy~ is causing me issue on Windows after a few hours of use.

Looking for a patch, or library that can help me getting this precious information when trying to put in place a low latency setup in pd:

I care mostly about:

• Deadline
• Load (AVG)
• Load (MAX)

I am currently on Windows... in Linux we have this information in Jack I think, and we know when a frame was dropped. I would like this information in pd or in Windows if there is a free software.

Cheers~

As usual thank you for all the informations @whale-av
@jameslo Perfect, I will be able to use a toggle in pd to invert the phase then!

I am currectly looking at those solutions for room calibration, I simply don't have a good ear

Have a good one!

Hi all!

I have access to a space with 8 speakers, they are in multiple rooms:

The gear (showing for 6 speakers)

I want to use pure data to control the volume of each room and to also select stereo or mono (or even try to play with 4.1 for ambisonics).

Here's what I have in mind for the patch:

ADC~
---
Gate
EQ
COMPRESSOR
hip~ (remove DC)
LIMITER
Mixer
VU meter
---
(stereo, mono, 4.1?)
---
DAC~ 1-2, 3-4, 5-6 with high pass (for channel using subwoofer)
DAC 7-8 for subwoofer with dedicated low pass (built-in in amp but fine-tuning)

Questions:

• Am I forgetting something important in the chain?
• Is there a patch out there to do Room calibration?
• Speakers are pointing at each other in the first room, I had in mind to invert the phase (the cables) but maybe I can use pure data to control that too (not sure)?

@whale-av I recall a patch you uploaded on this forum (like a mixer patch). Would it be interesting for me to use part of it?

Thanks for any advice!
