Great!

I think you don't need the connection from Pd to the PulseAudio JACK Source. This is mixing Pd's output with the mic and then providing this to Pulse apps' mic input... I'm guessing this isn't what you meant.

• system:capture --> PulseAudio JACK Source (mic available in Pulse apps, good)
• system:capture --> Pure Data (mic available in Pd, good)
• PulseAudio JACK Sink --> system:playback (can hear Pulse apps)
• Pure Data --> system:playback (can hear Pd)

... at this point, you're finished -- you've got all the connections you really need. Anything extra is likely to be confusing later, so:

• Pure Data --> PulseAudio JACK Source (Pulse apps can hear the mix of the mic and Pd, but cannot get the solo mic signal anymore, probably a bad idea except for Zoom meetings about Pd)

Also: Maybe look in the OS for security settings about the built-in mic.

On all my previous Linux machines, the built-in mic worked with no problem.

My current machine, I get nothing from the built-in mic, but I do get a signal from a headset mic plugged into the phone jack. I don't know if this is a configuration problem or if the built-in mic is disabled for security reasons... the headset mic is fine for my casual-use needs (obviously in a pro audio situation, I'll use a real mic with a USB soundcard, I'm not that lo-fi) so I'm not going to investigate, but it just occurred to me today that it could be security.

Hey everybody,

Sorry, for a lot of text. But the bold text at the bottom is my main question. The rest will help you to get a better understanding of my situation.

you helped me so much, with my last question here (the Faders are working dope now):
https://forum.pdpatchrepo.info/topic/13849/how-to-smoothe-out-arrays/25

I am doing a Steinberg Houston to Mackie Control emulation at the moment, to use my controller with other DAWs than Cubase/Nuendo. Will upload it to the internet community, when I am finished for the handful of people that maybe are also using this controller.

I made good progress:

I got the Faders and the normal knobs to work. And the display puts out information. But it is with bugs, because the LCD Screen of the Houston has 40 characters for one line and the Mackie Universal Pro has 56 Characters. So i did a list algorithm, which deletes spaces of the mackie message until the message fits on the 40 character line. Maybe there is a method wich will work better but this subject eats too much time for me at the moment and it works rough okay. One defenitely get's some helpful information on the screen from the DAW.

The Faders and Rotary Knobs and normal knobs are the most important of this controller I guess. The Faders are working fine as I mentioned above, but there is a problem with the rotary knobs, wich I can't handle alone and hope you can help me.

The problem is, that the Mackie Controller send simple clicks to the DAW. If you are turning a rotary knob, it sends out a number of midi messages:
If you turn it right, it sends midi messages wich contains the value 1 and if you turn it down it sends messages wich are containing the value 65.
"When the VPots are rotated rapidly, a message equal to the number of clicks is sent."

BUT the Houston controller instead is sending values like it's faders with 15 (MSB) and 128(LSB) values. AND it is updating the rotary limit by itself. So if I turn a rotary, it will update it's LEDs and stops sending midi messages when it reaches the maximum or minimum value. So, I did this patch as a momentary state:

Rotary Encoder Example.pd

The DAW sends 11 values for the Houston LEDs. 11 is max and 1 is min. This is good, I send this values to my houston controller and can update the rotary values and LEDs.
With this updated values from the DAW, I can force my rotary knobs, that they don't stop to send values, because they are set to the values, which the DAW sends, every time I turn a knob. With this method I got it to work to imitate a Mackie Rotary knob. Everytime the Houston Rotary value changes, it sends Mackie "midi click values" according to the amount of midi value changes of the houston.
BUT the problem is, that this is working only in one direction. Now my main question:

How can I make pure Data know, if I am turning my knob in the left direction or in the right direction? There is also the problem, which I mentioned above, that I set the momentary value everytime, I move the rotary, so that I get a unlimited amount of possible rotary move "clicks". Also the midi values which the houston sends arent perfect smooth. It works fine, but it isn't like that, that if you move a rotary in one direction, every value one by another is perfectly lower or higher.

I think I maybe need a algorythm, which looks if the values in a time period are getting higher or lower and then send out bangs on two seperate outlets. For example the left outlet for lower values and the right outlet for higher values. And it should also detect, if I move the rotary fast or slow. So a constant smoothing or clocked bang is also not an option. This is defenitely to complicated for me. I have no idea and what I tried didn't worked.

Would be super cool, if you could help me out again.

@Bangflip Maybe you have seen this discussion...... https://discuss.cakewalk.com/index.php?/topic/19846-mackie-control-questions/

The Mackie control is supposed to spit out a direct linear midi slope...... Mackie Control Midi Table.pdf and only clockwise/counterclockwise and count for rotary encoders (like the BCF2000).

In the discussion above "skavan" has given an approximate formula for a linearization of the Cakewalk curve. Maybe there is other information out there or a question on a Cubase forum would shed some light.
Or maybe the curve is the same in Cubase as a lot of the software developers were moving around as Cakewalk folded.

Hey, thank you for the discussion link!

Also for the Mackie Control Midi Table. This link, I already knew, and is very helpful.

If you have jitter in the slope then make absolutely sure that you have no midi feedback anywhere in your setup....... I am a bit embarrassed to mention that as it seems you know what you are doing......
David.

I already made sure, that there isn’t any feedback. I also think it has maybe something to do with my configuration or the values, Cubase sends out, because the little midi drops are always the same with continuus raising of the Cubase Fader.

I am experienced with sound design, yes, but I am more a creative, not a technican or programmer. It‘s a project, to invest some time and learn pure data for me.

I am thankful for every tip.

Hard to tell without more details. I also have no experience with motorfader-hacks, but am interested.
At a precision of 1600 values it is very likely some subtle hardware bouncing, resonance of motor, dirt or similar ?
How slow do you drive them?
I would maybe try to eleminate the discontinuity on the hardware / measurement side, instead of cheating.
Do several measurements, instead of one shot only.
Also try to drive it from Pd instead of Cubase. Very slowly. Calibrating. Remember, there is some latency, too.

Anyway, this is what you where asking for, I think:

@lacuna Hey, thank you very much, for your help and the patch!

I will now describe more precisely, what I would like to do. I thought, it would be a little bit off topic, because it is a bigger project.

Also, I think, I described it not correctly with the motorfader recording. That isn't true. My english is not the best, so my formulations arent always on point, but I will try my best.

So, to describe my Project, I am working on:

I have an old 20 years old "Steinberg Houston" Midi-Controller, which works via the Mackie Protocoll. It was specifically designed as a Cubase / Nuendo Controller back in the days. Cubase / Nuendo are also, as far as I know, the only DAWs with which the controller is working nowadays.

Almost all DAWs are supporting the specifications of a "Mackie Universal Pro" Controller. So I would like to program a Midi-Data Converter, so I can use my controller with other DAWs as a "Mackie Universal Pro" Controller.

At the moment I already found out, which midi Data the faders send and which midi data the DAW Cubase sends to the Controller. I also converted the Midi Data, so that I can use the controller faders, while Cubase thinks, it is a Mackie Universal Pro.

So, but the problem, why I started this thread is, that I noticed, that the Mackie Controller needs to get different values from the DAW to get the right fadermovement done, than my Steinberg Houston. For example: When I set my Fader in the DAW to 6 dBFS, my Conroller Fader moves correctly to 6 dBFS, as that is the highest fader value in Cubase. Also the other way around. If I set the Fader in Cubase to -00 dBFS, also my Fader of the controller is at the right position. So the lowest and highest values are correct. But if I set -20 dBFS in Cubase via Mackie UP Mode, my controller sets the fader to -10 dBFS. In the original Cubase "Steinberg Houston" mode, the fader movements are very precise and always are reflecting the number, which I set in the mixer in Cubase.

So my Idea was, to first send all Pitchbend values from Pure Data via Midi to Cubase in Houston Mode. I tricked Cubase in thinking, I would use the Houston Controller, but used Pure Data instead, to be very precise. Then in the preferences of cubase, I deleted all automation smoothing and set up a tempo in Cubase and with Metro in Pure Data, so that each 8th note, one pitch bend value is send to Cubase. and I synchronised both my DAW Cubase and Pure Data with a C3, sent from Cubase, when I start the Playback in Cubase. This C3 is then sent to Pure Data and than acts as a bang in PD to start the metro and sends the Midi Values. This midi Values are written then in Cubase as a Automation.

Then after that, I did the same process again, and recorded the Automation Values in Pure Data. But these values arent as smoothe as I would like to have them, even I recorded them that slow, that I set a metro of 8 per second which is for the 14 Bit values something like half an hour. The faders are the most important feature of my Controller for me, so I take the right amount of time to get them very precisely.

Between: I also found out the SysEx values to display what I want on my two rows houston display with Pure Data which was fun.

Hey, I'm trying to get purr-data to work on my fresh Manjaro XFCE install, but it does not work. Any help is greatly appreciated!

latency-tester right,

it's not. here some fixes:

latency-tester2.pd

[throw~] and [catch~] do bring some latency with them as far as i know...

It depends on the execution order, described in 3. G05 of Pd documentation.

Patching like this has no latency for your 2nd and 3d version, as for dyncatch~ and throw~ chatch~ and s~ r~.

But there is other trouble with the 2nd and 3d version:
Deleting by 'dynamic-mouse-clicks' doesn't work if I use Pd's zoom-in, as I usaually do.
This is a bug of Pd: it messes up the coordinates.
Same happens if I undo after moving an object, it reappears somewhere else...

In SC, I can arrange mixer channels in the order source --> target
[...] looks like the only way to force order is using an explicit patch cable

Not sure, but I belive only the order of objects is important, and even msend~ v1 could have 0 latency, if it would care about creation order!? Even across multiple patches? Creation order = execution order ?

Edit: yes and no: it's the creation order of the whole chain ...
in latency-tester2.pd:
[pd latency-meter] is the first object, [pd click] comes later,
... so deleting the patch-cord between [pd s] [pd r] brings back block-latency.

@ingox said:

[msend~] and [mreceive~]

yes!!!

@lacuna said:

dynamic patching:

but both introduce latency dyncatch~ 1 block, msend~ mreceive~ ~3blocks

http://www.pdpatchrepo.info/hurleur/latency-tester.pd

https://forum.pdpatchrepo.info/topic/7710/latency-on-output-and-input/2

I know that using send~ and receive~ introduce latency

Not necessarily. You can in fact force the receive~ to be scheduled after the send~, in which case there is no latency, just like with delwrite~ and delread~.

and am wondering whether using subpatches via inlet~ and outlet~ also introduce latency.

No, unless the inner patch has a bigger blocksize than the outer patch. In that case, the latency is the difference between the two block sizes.

Does send (without tilde) introduce any latency?

"latency" doesn't exist in the message domain. When you send a message to [send], it is delivered instantly to all receivers. There is no semantic difference between using [send] or patch cords.

Does using subpatches rather than one big page introduce latency?

No.

Hi guys,

I'm quite new to PD and especially with dealing sounds, and I'm trying to deal with multi-input sounds with mics on multi-outputs speakers.
Here's my installation :

• 2 mics connected to a sound card 1
• sound card 1 connected to the linux pc with PD (pd-l2ork-2.4.2)
• linux pc connected to an other sound card 2 that deals with 8 speakers.

What I managed to do so far :

• With one mic connected to the first input I can get the input signal and read it in PD with {adc~]
• I managed to throw this sound live on one of my 8 speakers with a {throw~], this part works fine I can hear myself live on any particular speaker.

Now I would like to implement a kind of switch that allows me to say at any point :

• Mic 1 or 2 is getting sound, throw it to speaker 1 to 8
• Both Mic should be able to speak at the same time (not on the same speaker though)

I tried some stuffs with [spigot~], {*~], [route] but can't figure out the logic of it. I would say that I need to send info with a toggle that this mic and not this one is getting sound, an another info that the sound should be heard on this speaker, but so far can't get it right.

If you have any help it would be welcomed

Thanks !
Florian
