But it is possible to set the string of a send object if you create it empty, like [s]. With this you could have one receive at each place and create and set the destination at the send point according to the logic of your patch.

Like for example you can build a little send machine:

send-machine.pd

@whale-av you are absolutely right. I have two machines with same os, pd, libs versions but different hardware. On the problematic machine I installed pd in a ubuntu 17.10 virtual machine and pd patches look correct. Should be a bug in the video driver version included with Ubuntu 16.04 LTS.

Thanks,
Ananth

@LiamG @ilpoj
As I suspected, the startup preferences are stored in the registry.
It is likely that windows 10, pursuing the same lockdown techniques as OSX, is not allowing Pd to write to the registry. Google might get you further than this forum.
Everything..... paths, startup options, libraries to be loaded, audio and midi options are stored there.
If you cannot load libraries, or save your settings then that is because you cannot write to the registry.... it's part of the same problem.
I can post my settings that you could paste into your registry (and then modify) if you wish.... obviously at your own risk!........ but first.....

You can right-click the folders in the registry and change permissions.... which should be a zero risk.
Open Regedit and find the key folders listed below and check their permissions.....
You might need to open regedit with admin permissions.
You could also try opening Pd with admin permissions and trying to install cyclone and set paths, but I think it is wish85.exe that accesses the registry.

Vanilla and Extended preferences are stored separately in the following locations (Windows 7)....

HKEY_CLASSES_ROOT\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Pd
HKEY_CLASSES_ROOT\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Pd-extended
HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Pd
HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Pd-extended

This one twice...... probably last known good, and?
HKEY_USERS..."long string" ... Software\Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Pd(and Pd-extended)
The "long string" will be different to mine on your machine.

@LiamG The garbled paths can be corrected and saved again....... which usually solves the problem.
That seems to be particular to Vanilla.
David.

@LiamG said:

I think it should also be mentioned that the Purr Data GUI is more CPU intensive than Vanilla. It probably doesn't matter much on faster machines, but it might be a factor if you're running on a slower machine.

That's true-- you'll definitely notice the difference on a machine with single CPU. On multi-core machines the GUI shouldn't be getting in the way in the course of normal patching operations. (Especially if you run Pd with realtime priorities.)

The actual chatter between the GUI and audio process should be less, though. For example, if you move a selection of objects it's just a single message rather than one message per object. Also, textbox edition doesn't touch the audio process until you re-instantiate the object/message.

But like Pd Vanilla, you can still trigger dropouts by moving the mouse over a patch if there are enough objects on the canvas. Someone started doing work in the direction of fixing that. But it's very tricky to get right without breaking some random Pd ninja's use of Pd's unspecified interface.

However, you can set event callbacks for the new [draw] commands without sending streams of "motion" messages to the canvas. So there's that.

I changed my first post and uploaded a zip at the end.
Works with Purr Data or pd (plus zexy)

@whale-av
Thanks for your patch. I tested it with extended, but I get latency issues. When I record saying something like "tik" on the beat, the "tik" is heavily delayed to the metronom on playback. But on pd extended I can't set the latency lower than 24 msecs. So there might be some issues with extendend on my machine. (pd or Purr Data let me set the latency to 5 msecs without problems.)

You wrote: The biggest problem with (not noticing) an edit will be a difference of volume (power). Our ears are very sensitive to that.
The second biggest problem will be the quality.... timbre..... but as you say a crossfade could help. But the bigger the difference the longer the crossfade needs to be.
I thought about starting recording a little bit earlier and stop somewhat later, so I can crossfade between these extra samples. And maybe it's easier than I thought.

@LiamG
Thanks. How can I trigger between blocks? I thought messages are only send once during a block, aren't they?
About 3): I was wondering, if it is a problem, not to be able to set the exact metronom tempo

And here's a little screenshot to see what it looks like:

I would say, anything above 5 ms latency between the metronom and some voices starts to feel strange. And when you start to change your reference - say you start recording with the metronom, change to first recorded line as a reference, than to the second etc, - the latency will sum up and increase.
I wonder how latency is treated on hardware loop stations.
And I'm still asking myself how latency should be treated to get it right.

Xaver

I have a big patch that ultimately outputs to an arduino that then controls relays that fire strikers that play a gamelanish assembly of music. Here's a link to vid of the working machine:

So the problem is, it works great, always seamless on my computer (MacBook Pro (15-inch, Early 2011) 2 GHz Intel Core i7 4 GB 1333 MHz DDR3, but when I try to run the exact same patch to the same arduino using another machine (last attempt was a MBPro 13 inch mid 2010, 2.4 ghz intel core 2 duo 16 gb 1067 mhz ddr, but it's happened before on a machine I don't have the specs for right now) the comport almost immediately runs into serial overruns and shuts down the comport. I'm running at 115200 baud.

I'll admit I'm not using the most efficient means of serial communication, but aside from that, it does work on the machine it was written on. The machine that it is not working on is more powerful than the one that it is...do I have a magic computer?

I uploaded this Wavetable Drum Machine last year but it became a casualty of a server issue (I hope it didn't cause it, it is a bit heavy). Anyway it didn't work under windows so while I was updating old drum machines I sorted this one out.

Here's the instructions, which are also under the Balwyn button.

Wavetable Drum Machine
Balwyn 2015

8 x bank of 64 amplitude sliders, each bank runs in sync driven by a clock. The clock has 16 start/end settings plus a repeat cycles setting, there is also a Vradio block to set the return position.
The mixer block has 8 x level & pan settings with stereo to the dac~
The wave selector is for loading the individual wav files to the relevant drum line. The *.wav files must be stored in the 'waves' folder within the program folder and selected from there.

Saving must be saved to the 'pattern' folder within the program folder. Save the file with one word and no extension, a file of that name will be created for the pattern settings. Another file with the same name will also be created with the extension '.kit', this stores the names of the wave files.
Loading must be from the 'pattern' folder within the program folder. All the clock, pattern and wave files will be updated. select only the file WITHOUT the .kit extension, otherwise nothing will load and soundfiler errors will appear in the Pd window.
The clear button will clear all the amplitude sliders, set all the clock settings to 1 except BPM which is set to 500.

The supplied samples were recorded via Audacity from Qsynth. Ditch them for your own
Cheers
Balwyn

anyone having the same issues or an advice=? ?

thanks!!

@flextUser Hello....... A custom Ubuntu Live cd will be running Ubuntu on the laptop...... so the fact that it ""was"" a windows machine is irrelevant. The live cd will need to run on that machine........ have all of the video/audio etc. drivers that will work on that particular machine......
Linux is pretty good at that now, but you will need to check on the actual hardware.
Then you might need the drivers for his hardware, soundcard, joystick, etc.
Depending on the complexity of your patch the usb stick will need to be fast enough.

I would try running the basic live cd first, with your patch on another key, and see what needs to be downloaded/added to get it all running (on their machine)....... if it will run straight away then you are lucky.

Yumi....... http://www.pendrivelinux.com/yumi-multiboot-usb-creator/ I have used and it is not bad for getting going with the Linux Ubuntu drive......... from then on you will start to get an idea of the possible problems. Make sure that you take the option to have a writable file on the drive so that you can save setting, preferences etc.
The computer that you are going to boot from the drive will need a bios where you can put "boot from usb drive" (or similar) to the top of the boot order.............
There is a lot of useful help on the left side of the web page that I linked to.........
Ps again! I didn't mention....... but its very important...... that the usb Ubuntu, Pd etc. must not write to the computer hard drive while it is running....... as the windows that is installed will not know about the writes........ and that will risk windows not booting again afterwards when the Ubuntu key is removed and the computer is rebooted normally......
David.

I just installed Ubuntustudio 15.10 Wily Werewolf 32bit on a thinkpad and I am trying to upgrade PD to extend. I am fairly new to linux but it seems like the instructions on https://puredata.info/docs/faq/debian fails.

This is the log from executing the commands. Any suggestions and help will be appreciated
