Wow, perfect, even works in subpatches ! Exactly what I was looking for. Looks like I still need to catch up with latest pd improvements. Thanks a lot, IOhannes.

Getting 32 bit floating point number from 4 sequential bytes
by Arda Eden 09 Apr '19

09 Apr '19

Hi, I am trying to write a Pure Data external for getting real time motion capture values from an Xsens system. According to the manual ( https://xsens.com/download/usermanual/3DBM/MVN_real-time_network_streaming_…), the x, y and z coordinates of the skeleton segment positions are transferred over network (udp) as sequential 4 bytes (32 bit floating point - big endian). I am reading the udp data with [netreceive] succesfully and able to reach any value I need. Now trying to find a way to combine these (big endian) sequential 4 bytes in order to get the resulting 32 bit floating point number. A little advice would speed me up. By the way, I studied the [oscparse] source. It was very helpful in most ways but also a little complicated too. Thanks already. -- Arda EDEN Yıldız Teknik Üniversitesi Sanat ve Tasarım Fakültesi Müzik ve Sahne Sanatları Bölümü Duysal (Ses) Sanatları Tasarımı Programı İstanbul/Türkiye Yildiz Technical University Faculty of Art and Design Department of Music and Performing Arts Audio Design Program Istanbul/Turkey

patcher scripting using $0 ?
by Joseph Larralde 09 Apr '19

09 Apr '19

I'm currently writing some GUI abstractions which have their appearance initialized by arguments. I'm using patcher scripting to achieve this. I wonder if there is a way to target a top-level patch in another way than using its patch name ... Being able to use $0 in the destination name would be great ! For example : I have a "soundbank" abstraction, which I initialize by sending messages to "pd-soundbank.pd" But what if I want to create various instances of this abstraction ? If I create a first instance, then a second one with different arguments, the first one will receive the initialization messages from the second one because it has the same file name. So for the moment I can only create one instance of this kind of abstractions, otherwise all the previously created instances get messed up by messages they shouldn't receive. Hence my question (I couldn't find such information in the docs). Thanks, Joseph

Implementing compressor as a patch?
by Alexandre Torres Porres 09 Apr '19

09 Apr '19

Howdy, I'm giving a try at how to implement a compressor as a Pd patch. This is what I came up with, it needs cyclone 0.3! Here's a screenshot. I'm using rms average to detect the gain level and rampsmooth~ to perform attack/release. I wouldn't know how to do it in Vanilla... [image: Screen Shot 2019-04-07 at 23.42.22.png] Seems rough and rudimentary. It's more of an intuitive approach, as I don't know much about compressor design. I'm hoping to get feedback from you people on how to implement a compressor in Pd as a patch and how and why this approach is "ok" and can be improved, or if it's all terribly wrong. Are there any other attempts to implement compession in Pd out there? Thanks Cheers

I implemented an external based on this excellent paper in my lib "jl" (which is available on deken, see the source here : https://github.com/josephlarralde/jl.pd.lib) It's called [sidechain~]. I'm happy enough with it to use it in concert.

ubuntu not suspend if camera connected
by Csaba Láng 08 Apr '19

Dear List, sorry for the off topic, just do not know who to ask. I cannot suspend my computer if any usb webcam is connected to any of the usb ports. Is there a way to ignore the cameras, or unplug it more system wise and not physically? Thanks for any hints. Best, Popesz

Gem 0.94 - camera settings on windows ...
by oliver 08 Apr '19

08 Apr '19

hi, i am trying to make a patch involving a live camera on PD 0.49.0 (64bit) with Gem 0.94_pre1 (64bit) on a windows 7/64bit machine. so far everything works alright, but i can't set the camera resolution ! unfortunately the default resolution is 160x120, which is pretty useless. so far i found no way to change that resolution, the "dimen" message does nothing and setting width/height via the props method also doesn't work. now here's another strange thing: with PD 0.48 and Gem 0.93 (both 32bit), when i opened the camera dialog (with the "dialog" message to [pix_video]), 2 windows opened: 1 for the camera driver settings (brightness, contrast, exposure etc.) and 1 for the resolution. so with the fomer (32bit) version of Gem i COULD set the camera resolution to the desired dimension. however, sending "dialog" to [pix_video] in the 64bit version described above, i only get 1 window, the one with the driver properties (which btw i can also set via the "props" method) can anybody help me in this regard ? is there a workaround to manually set the camera's resolution ? unfortunately i need the 64bit version of Gem because of the amount of RAM i need (i record video frames over some peroid of time, and the 32bit version is limited for my needs). plus the 32bit version doesn't work (i already reported that to the list) thanks for any hints best oliver -- \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ /////////////// http://pendler.klingt.org ////////////// \\\\\\\\\\\\\\\ http://oliver.klingt.org \\\\\\\\\\\\\\ ////////////////////////////////////////////////////////

sending patch + folder to PDParty
by enrike 07 Apr '19

07 Apr '19

hi I am trying to test in iPhone a patch built using PDDroidParty. My problem is that together with the droidparty_main.pd I have a folder with pd abstractions. For me the best solution to install the patches would be to send them into an email or some kind of message same as we do in Android: all zipped together in a .dpz file. We are going to be sending this to a group of people with different types of phones and we need to get this up and running as soon as possible. However the iphone does not recognises the .pdz as a PdParty file and it does not give the option to copy it to the PdParty folder. I can send them the .pd files attached individually but then I have to one by one copy them into the folder and they are a few of them. Is there any other easy to use method to send them all into the PdParty folder? thanks enrike
