I recently bought a UA Apollo twin mk2
to replace a scarlett 6i6. I am running Pd extended and I can receive audio out on the UA interface from a patch(on one channel), but not audio in via the adc~
Any similar problems out there with the UA and Pd?

/mac rant time - got a 2010 13" macbook pro about 5 years ago because it was an incredible value - (the 13" didn't have the graphics card problems) - I hate it now - its such a brick - but it will never die so I could justify getting a better laptop. the battery life is about 2 hours at best but you can open it up and change it but it still feels like a broken battery

my mom tho decided to go to art school a while ago so I bought her a decked out 2015 15" macbook pro one christmas so she could edit video and look like a cool person (she switched to interior design and ended up working at an SBC but that thing was always a champ at anything) - so jealous of that screen - the 13" is like 30hz 1280x700 - that 2015 mbp is really the best value right now - except the battery is legit glued onto the frame- they replace the whole bottom shell when they fix it at the genius shop - you can buy a repair kit that comes with glue dissolver. Well she was using crappy chargers and it quit charging so either the power part or SMC or the whole thing is broken and it's not worth it to try and fix it - fortunately the newish 16" is finally a decent replacement for it - so merry christmas - she uses it to watch TV when she travels - the audio on that sounds so good, and the over a day long battery life, its just the best laptop because its such a huge amount of tradeoffs to get a laptop right - I kind of wonder if people complain enough about the latency theyll focus in on fixing it. Theyre really deep into their own lore at this point - its annoying - even rosetta 2 - if they follow it then things will smooth out around version 6 and version 12 will be the high point

in summation: dongles

I'm curious tho - pretty sure opening the pd doc for the camomile VST3 with plugdata would fix the midi problem (because theyre both libpd under the hood the midi problem might be with the helper code or the JUCE backend besides the older version of PD/libpd camomile is at) and you can just run plugdata and patch live in reaper as a VST3 - has some extra DAW objects too.

it looks like focusright and motu are in a usb3 dac latency war as well .. I dont own anything with a usb-c port - I got dongles tho

Thanks for your work, i'm loving PlugData.
But I'm having a problem here, Made a patch i want to use with 4 channels, but i can only select 2 at a time. When i select channels 3&4, it deselects 1&2 and vice-versa.
Patch works fine on PD, but looks so much better no plug data.

Im using a mid2015 macbook Pro with plug data 0.6.2 and Focusrite Liquid Saffire 56.
Thanks

Hi everyone,

I've been playing a bit with a Csound handpan synth from here and I've used the r_cycle external to make a handpan with my Launchpad (the patch is not very complicated so I didn't try to make it neat, sorry!).
The csound patch maps specific MIDI notes to the synth according to a scale, and the Pd patch lights up the pads so each colored group of pads sends the corresponding MIDI note to CSound:

I'm super happy with it, but the next step is to make it configurable: the csound patch contains many different scales defined with giNotes = ftgen(0, 0, -<number of notes>, -2, <list of note numbers> ) :

; B Kurd
;giNotes = ftgen(0, 0, -10, -2, 47, 54, 55, 57, 59, 61, 62, 64, 66, 69)

; B Golden Arcadia
giNotes = ftgen(0, 0, -9, -2, 47, 51, 54, 58, 59, 61, 65, 66, 68)

So instead of editing the CSD file and changing the color mapping of the launchpad when I want to change scale, I would like to send a list/array/table of note numbers from Pd to [csound6~] via a message (and adjust the MIDI notes sent by the launchpad at the same time).
I know basically nothing about Csound, so I've read up and found examples using chnget/chnset or invalue which seem relatively straightforward to change the value of a single int variable. However I don't really have any idea on how to pass the list/array of scale notes using chnset or invalue, or if there is a better way to do it.

Maybe someone around here has an idea? Thanks for reading so far in any case

Scarlett 18i20

Awesome, thanks a lot for the reply! That really helps!

I know that 10 is no problem. I have an 8-channel interface which is connected (via ADAT lightpipe) to an 8-channel preamp, and I can and do use 16 ins and outs.

It's a Scarlett 18i20 1st generation and an Art TubeOpto 8, and I'm running Linux. I don't know if any other situations would throw unanticipated roadblocks, but this kind of setup seems pretty universal.

I think I finally figured it out!
Well, not sure it solves all my problems, but at least here is a limitation of pd~: midi inputs and outputs (obviously)! There were a few of those in one of the libraries called by mybigpatch.pd (r_cycle).

So here is my way around it, in case it might help others:

• In the main patch, capture notein and send [notein $1 $2 $3( to [pd~]:
  
• in the pd~ subprocess, capture the incoming in an abstraction ./myfolder/notein.pd:
  
  and replace all instances of [notein] with [./myfolder/notein]
• similarly for noteout, an abstraction ./myfolder/noteout.pd to use in the pd~ subprocess:
  
  and replace all instances of [noteout] with [./myfolder/noteout]
• in the main patch, replace noteout with [r noteout]:
  
• and the same thing with ctlin, ctlout, bendin, bendout, midiin, midiout, etc.

And the command line magic trick (that it took me a while to figure out) in order to replace all this easily in all pd files:
$ sed -i 's+\(touchin\|polytouchin\|bendin\|notein\|ctlin\|midiin\|midiout\|noteout\|ctlout\)+'./myfolder/'&+' *.pd, which will prepend any instance of notein & co with ./myfolder/.

Improvement suggestions are of course welcome.
Cheers!

@whale-av Hi David, thanks for the suggestions.

In order to satisfy all ENT parameters, the best option is to get the varying amplitude from [env~] and using [mod] to evenly spread the values.

Here the test of a so generated 180.000 byte bin file, the results are within the normal required parameters.

Entropy is 7.999070 bits per byte. This value is the information density of the contents of the file, expressed as a number of bits per byte. So the file is essentially random.

The chi-square distribution is 84.08%. This test is the most commonly used test for the randomness of data calculated for the stream of bytes in the file and expressed as an absolute number and a percentage which indicates how frequently a truly random sequence would exceed the value calculated. If the percentages is between 10% and 90% the sequence is random.

Entropy = 7.999070 bits per byte.

Optimum compression would reduce the size
of this 180639 byte file by 0 percent.

Chi square distribution for 180639 samples is 232.49, and randomly
would exceed this value 84.08 percent of the times.

Arithmetic mean value of data bytes is 127.6331 (127.5 = random).
Monte Carlo value for Pi is 3.132000266 (error 0.31 percent).
Serial correlation coefficient is -0.000969 (totally uncorrelated = 0.0).Insert Code Here

@tarim Difficult to diagnose, but as it is an asio device you will need to match the Pd settings to the device.
Change the Pd settings..... not the Focusrite settings.
Open up your control panel for the focusrite and check you have the same sample rate and the same buffer.... 64, 128, 256 etc. Buffer is "block size" in Pd.
Then it should work .
Probably ticking the "use callbacks" box is a good idea.
When it is working try reducing the Delay (msec} to 5.... then 4..... then 3...... until it doesn't work any more and then go back to the last value that worked. That should give you the lowest latency.

If you have no luck at all and you are using windows then try Asio4All...... http://tippach.business.t-online.de/asio4all/ .... instead of the Focurite driver. It will allow you to use more than one device at a time as well.

@julietaz Not sure.
Normally you can set the audio outputs in the Pd menu > Media > Audio Settings.

and maybe you just need to set for the Focusrite..... "Channels" 4
If you are using Windows you can use "Asio4All" http://tippach.business.t-online.de/asio4all/
for low latency audio and select ASIO in Pd settings and then the Asio4All driver which will allow you to use all the channels of the Focusrite and the PC speakers.
Without Asio4All you would need to select "use multiple devices" in the above screenshot.
