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!

For some reason pd doesn't cooperate with my Bose Soundlink bluetooth headphones on my Macbook (2015, running next-to-latest OS, most-recent pd and pd_iork builds (tried on both)). It only does audio from the right inlet of the dac~, which it interprets as mono--the left inlet doesn't work at all and there is no stereo. Other than pd the headphones are fine and stereo and everything. And I made sure the audio settings had it listed as 2-channel.

I tried the same thing on my Windows computer and found that Windows has an option where those headphones can be interpreted as either headsets (1-channel, apparently what pd says) or headphones (stereo)--by default I was getting the same 1-channel response as on the Mac, but I was at least able to change it in the Windows preferences, an option that seems not to exist on Mac.

How can I tell pd on the Mac that they are stereo headphones, so I can work with both channels? (Or, and I realize this is a Mac question, not pd, how can I slap some sense into the Mac?)

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

Hello everyone, ive got this problem while trying to connect my arduino to Pd. Already installed firmata, used firmata test app to check its ok, and it is. But when i open the arduino-test pd patch, i get this:

Any ideas? I see that moocow is missing (and that could be relevant), but couldnt get anything using the "find externals" function.

Most families have a kitchen blender of certain sorts. A portion of those blenders are more remarkable than others. A few clients are more proficient than others with regards to recognizing what a blender can do. Recognizing what your blender can do can set aside you cash and enhance your cooking experience just as spare you https://goodfoodblogph.com/ time in the kitchen.

Mixed Drinks

Each child realizes that blenders are remarkably acceptable at making mixed beverages. Blenders can make milk shakes, smoothies, natural product shakes, solidified beverages, and the more remarkable blenders can make squashed ice for margaritas and daiquiris. These beverages can be made with and without liquor. Blenders are ideal for family social occasions, local gatherings or for the each morning power drink.

The blender's capacity decides how smooth your beverage will be. On the off chance that for instance you are including almonds or carrots they will be separated into a lot littler parts the more remarkable your blender is. What's more, in the event that you do like lumps in your beverage and you have an exceptionally ground-breaking blender then you simply need to decrease the mixing time. Anyway it doesn't work the reverse way around. In the event that your blender comes up short on the force it will always be unable to deliver a truly smooth mixed beverage, particularly when utilizing more strong things.

Purees, Dips, Salsas and Soups

Blenders are the ideal kitchen apparatuses with regards to making purees, plunges, salsas and soups. You can make any kind of soup you need, simply include 1 cup of cooked vegetable, some cooked boneless chicken on the off chance that you like, and a ¼ cup of water to your blender. At that point mix until it is smooth enough for you.
You can without much of a stretch mix any of the accompanying: avocado cream, guacamole, cream of mushroom/tomato, Mexican salsa, dark bean plunge, new organic product yogurt, new pesto sauce, fruit purée, and some more. Numerous sound and fun suppers and bites can without much of a stretch be made with the correct blender, frequently setting aside you time and cash all the while.

Infant Foods

Who would not like to take care of its infant new and solid food. Blenders are a simple method to make a variety of various enhanced and supporting infant nourishments. From fruit purée to carrot puree to verdant green squeezes, all can be newly made and individualized to give you 100% control of what you feed your child. This will likewise spare you a great deal of cash as well.

Pounded Spices and Fresh Grinded Coffee

Envision pounding your own new espresso each morning, or on the ends of the week. Envision the smell and the full flavor that you get from newly crushed espresso. There is then no requirement for you to stop by a coffeehouse on your approach to work and drop $4 or more dollars each time you need great new espresso. The more impressive blenders can crush espresso beans as fine as you might want them to be.

Make your own newly ground pepper from peppercorns. You can even make your own pepper mix by combining various kinds of peppercorns. Do likewise with nutmeg, cinnamon and other dried flavors. Whenever you have visitors over for supper or BBQ dazzle them by revealing to them that you made the flavor blend yourself.

Crushed/Shred Meat

Make your own burger patties from lean cut meats and set aside cash all the while. Additionally, another preferred position is that you know precisely what meat is truly in your patty. Shred cooked meats for sandwiches, e.g., chicken or pork. For this Best Blenders suggests an incredible blender.

Cleaved Vegetables

Do you scorn cleaving onions? Why not utilize your blender? You need hacked carrots as well? Not an issue, utilize your blender. Utilize a low setting or the beat highlight on your blender https://www.flickr.com/people/blenderforsmoothiesreviews/ and the activity will be done right away. It doesn't make a difference on the off chance that they are dry or wet, a decent blender will cleave them to an ideal serving size in no time flat, sparing you time and tears.

Ground Cheese

You like including ground cheddar your pasta or making new pizza or meal? At that point why not utilize newly ground cheddar? It is exceptionally easy to do - cut your cheddar into 3D squares, throw into your blender and utilize your blender's heartbeat include until you have the cheddar ground to your ideal size. Newly ground cheddar consistently tastes better!

Serving of mixed greens Dressings and Mayonnaise

Practically any blender can make serving of mixed greens dressing. Pick your dressing fixings and mix until smooth. At that point bottle it for next time or to take it to the workplace or cookout.

For mayonnaise the fundamental formula is two eggs, 1 tsp. mustard and ½ crushed lemon (whenever liked), mix at fast until foamy, at that point gradually include 1 ¼ cup cooking oil and keep on mixing at rapid until thick and rich. Spot not utilized segment into a container and store in cooler. All new and scrumptious, and everything is without additives.

Crushed Whole Grains

You like eating entire grains? What about creation entire grain flapjacks? It is without a doubt less expensive than locally acquired blends, and truly easy to do as well. Most don't know that a blender can deliver a fine powder from entire grains. The blender ought to have more force than a normal home blender for this errand.

Frozen yogurt

Make the most extravagant seasoned frozen yogurts ever with your blender. Ideal for birthday celebrations or home film evenings. Truly easy to do as well, as relatively few fixings are required. It is additionally remarkably simple to store your newly made frozen yogurt in the cooler until one week from now or the end of the week after. With a bit of testing your companions will before long be advising you to bundle your frozen yogurt and sell it. To make frozen yogurt your blender will require enough mixing capacity to have the option to deal with solidified products of the soil in the event that you decide to utilize them. The more remarkable the blender the creamier and smoother the frozen yogurt.

Additive Free Fresh Nut Butters

Make your own new nutty spread, or almond or cashew margarine. Ideal for snacks, picnics or bites. This can be a solid and reasonable choice to locally acquired items. Envision the expression on your companions faces when you disclose to them that you make it yourself. Here is the way to make new nutty spread https://gab.com/topbestblenderreviews without any preparation utilizing your blender.

First mix 2 cups of cooked peanuts and ½ tablespoon of vegetable or nut oil until it becomes glue like. At that point taste and if necessary include minuscule amounts of earthy colored sugar, nectar or salt to fit individual taste. On the off chance that you like your nut spread crunchy, include some more peanuts at the end and mix just for a couple of moments. Best Blenders suggests the more remarkable blenders for this kind of mixing.

Firstly, I would strongly advise against using the IAC driver at all. It is known to have various issues and I have solved multiple reported Mac Pd midi problems on this forum by simply convincing people to completely deactivate IEC in the Mac midi prefs an stop using it altogether (you can search my posts on here for details on the "why").

You do need a third party app to interface that unfinished Mac midi implementation. I would recommend MidiPatchbay which I can personally vouch for as I use it all the time, or possibly MidiPipe, which I have less experience with. Like IEC, you can use those programs to create all the virtual midi ports you need as well as do much, much more such as port/channel rerouteing, translation etc.

Now that said, there's a certain trick you need to know to get it to work with Pd. You can presently only get access to the first 9 of Pd's internal midi ports with Mac OS, but they will not reliably connect to anything beyond the first nine ports on the Mac's midi port list. For this reason you must first make sure that you start out with all midi ports deactivated, then create/activate your nine virtual ports. Then (and only then) you should start Pd and connect it to the nine ports you created. You can then activate all the midi ports on your system and use the third party midi app to route to any port you like. You have to do it in exactly that order or it won't work.

I am pleased to report that there is currently some headway being made in fixing the various long standing midi problems in Pd -- Hopefully in the near future you will be able to connect Mac Pd midi directly like any other midi app without having to go through any of this redundant silliness at all.

@whale-av hey david which one would you recommend?

the guy at the mac store was i think just trying to sell the most expensive one he could, i like the mac mini, but he said it wasnt good enough for my work haha :/
i think the mac mini is pretty powerful.

Finally, it's done! The most polished release of Pd yet. We are further refining Pd into a truly powerful and usable programming platform.

http://puredata.org/downloads/

This release is dedicated to Jamie Tittle, aka tigital, who recently died of cancer. He was a long time and key contributor to Gem and Pd in general, even while he was in the hospital undergoing treatment. He is sorely missed in this community, and I am sure by many others.

Some highlights of this release:

* more functional namespace tools ([declare] and [import])
* new appearance designed to enhance readability
* GLSL shader support in Gem
* usability improvements
* on Mac OS X, you can now build "standalone" applications
* standard locations for user-installed externals
* many bug fixes

Here's the rough changelog:

• next visual appearance designed for readability

• default locations for user-installed externals, helpfiles, etc.
  GNU/Linux: /usr/local/lib/pd-externals and ~/pd-externals
  Mac OS X: /Library/Pd and ~/Library/Pd
  Windows: %ProgramFiles%/Common Files/Pd and %UserProfile%/Application Data/Pd

• lots of standard key bindings added:
  Enter/Return for OK
  Escape for Cancel
  Ctrl/Cmd-W closes all windows
  on Mac OS X, Cmd-` cycles thru open windows
  on Mac OS X, Cmd-m minimizes windows
  Ctrl/Cmd-R raises/lowers Pd window
  Ctrl/Cmd-Shift-R shrinks/grows Pd window
  Ctrl/Cmd-Shift-L clears Pd window's text console
  Ctrl/Cmd-B opens the Help Browser

• you can now use "~" in all paths to mean home folder, and on Windows you can use environment variables, lie %UserProfile% in paths

• improved Cut/Copy/Paste support for working in object and message boxes

• fixed Cut/Copy/Paste for the Pd window's console

• [declare] and [import] now sorted out for loading (but much work needs to be done before there namespace support is complete)

• "File -> Save As" defaults to the Home folder (~/) on Mac OSX

• new patches default to the folder last saved in

• included pgp_opengl aka 3dp on GNU/Linux and Mac OS X

• 'hardware' and 'deprecated' removed from libraries loaded by default

• On Debian/Ubuntu, the packages now install into /usr rather than /usr/local

• On Mac OS X, you can now build "standalone" applications from the File menu.

• bug fixes and clean up of [hid] and mapping externals

• included config in Info.plist for the Spotlight Importer

KNOWN BUGS

• check http://puredata.info/dev/bugtracker before reporting bugs

• Escape, Enter, and Ctrl/Cmd-W don't close the Path and Startup preferences

• pdp_opengl is alpha and will definitely crash Pd

• loading pdp_opengl will crash Pd if X11 is not open before trying to load it

• the GUI runs slower in some situations

The new visual style is very nice indeed,

Hi there,

thank you for your feedback !

@mod said:

wow, nice to finally see this!
why are highs contrary to what you'd expect? at a low sample rate, the highs are folded back into low frequencies, but when you upsample, the highs are preserved as true highs. i think it works just how it should. The upsampled version is certainly much clearer and brighter to my ears. Particularly with a high distortion level.

That makes sense. The upsampling workaround officially wins (I'll try x16)! I think I focus too much on highs, as I tend to find this disto patch rather 'acid'; the original sample sounds much darker than the distorted sound. I don't owe the actual pedal so I only rely on my 'feeling', which is far from reliable Of course it's logical to add highs with such a nonlinearity, and lows are filtered several times.
Anyway I still find the heavily distorted sounds have a strong 'schh schh schh component' in the highs, and I can't remember having heard that as strong in actual analogic effects. Would you agree with that? Of course I know this is a rather basic 'physically-informed' design, and that analog will always sound better

@mod said:

actually, this patch really demonstrates the effect of aliasing. if you turn the tone knob down as far as it will go, and also turn the distortion down to zero, and turn aliasing off, you can clearly hear the rustling noise caused caused by those wrapping frequencies.
turn aliasing back on again, and the noise is gone.

Very strange, when I do what you say, the upsampled version sounds like the 'not upsampled one', with a 'sch sch' noise added !

@nau said:

The BJT gains are bound to my 'signal amplitude policy' : input file or audio source and output should never clip. These gains can be seen as follows : the first one (before the clipper) adjust 'how early' distortion occurs, and the second one gives the distorted signal a boost in order to give similar subjective level than dry signal.
The values were found empirically.

This might be where I have the biggest issue, though the article doesn't make it so clear, either. [...] the DS-1 isn't a baby's distortion pedal.
[...] Also, you don't need to calculate the boost into the filter coefficients. That's only useful for plotting. You can just use [*~] before or after the filter do accomplish it.

I understand all these arguments. I'll modify the patch. At the beginning I was using this kind of reasoning, but as the 'nominal input level' is -20dbu (http://www.bossus.com/gear/productdetails.php?ProductId=127&ParentId=254#), and the dbu definition I found seemed difficult to bind to 'our' db, I just dared to make the basic (36db-20db=16db~6.3 times in amplitude) operation... not far from the 6 in my patch Not very scientific, though.
Anyway I understood another reason why my 'subjective hearing' failed: feedind my patch with a 0db normalised sample maximizes input level, and the result will always be 'over the top' compared to non-active guitar pickups with a volume knob not always pushed to max. In other words, if I look at demos on youtube the result heard will be less distorted than my patch's. Anyway this can always be seen as an additional parameter for a 'parametric DS1 deluxe edition patch'

@Maelstorm said:

As mod said, it's not so much more highs as less lows, and those lows are a result of aliasing. To my ears, the upsampled version sounds less muddy. (By the way, in your upsampled portion, you have a different argument for the second [DS1-bjt_stage~]. Making them equal makes the difference even less noticeable, and draws more attention to the mud than the highs.)

Ok, upsampling wins !

@Maelstorm said:

Yes, there is a difference, but it's not a Matlab thing. It's the choice of the logarithmic scaling in the x-axis. The article uses powers-of-ten as equal distances. Mine uses [mtof] for the scaling, so that a semitone, octave, or whatever musical interval is the same distance. Also, I made an adjustment so that everything between 0 and about 20 Hz (at 44.1k) gets squashed in the leftmost 10% of the graph. If I didn't to that, then about half the plot would be taken up with frequencies below the audible range.

Ok, perfect ! Everything's cool now.

@Maelstorm said:

(commenting peaking after ToneStage)
This has nothing to do with your tone stage. It's because of the passband ripple in the Chebychev filters. The IEM Chebychev filters have a 1 dB ripple, though I don't actually know if that means +/- 1 dB or +/- .5 dB. Either way, it's creating a boost at some frequencies, and pushing the output down by 1 dB should keep it below [-1, 1]. This could also be contributing to the highs, as the ripple is typically more pronounced near the cutoff frequency.

Mmh, I thought the same, but then I decided to check the plots taken out of the 'not upsampling' part, and the peaking is still there ! The Chebyshev filters can be the source, then ...

@Maelstorm said:

The output from [tanh~] will never clip, so as long as you make up for the ripple and don't boost the second BJT stage, you should be fine.
[...]
Just one more thing to add for now, and that is you're doing too much in the upsampled portion. The only thing that needs to be in there is the non-linear function ([tanh~]) and the anti-aliasing filters. Everything else is linear and doesn't benefit from upsampling, so it's just creating more computational load.

Of course I precisely want to get rid of this peaking to be able to fully rely on [tanh~] to 'master' my output gain. I'll try the FIR instead of cheby (as proposed by acreil) some day. (I don't even know yet how they work and how I'll have to implement it).

I left the 'full upsampled chain' in this patch only to see if someone would have commented it, and we totally agree. But this 'playing the noob' attitude of mine is a rather raw 'fishing method' for getting stimulating information ... sorry this lead you to lay down the whole picture BUT nothing wasted, as your final 'delicate' -1db cut surprises me and I'll use it (when I'll get rid of peaking) and moreover, as you are reminding me that you use a 18000 cutoff freq, I'll give a look again at it, just trying to find a good criterion to pick one

Thank you everybody,
See you,

Nau

P.S. : sorry for those very long sentences ... not very clear
