(this is a duplicate post i did on the forum, but want to see if i can get help here)
is there someone here doing pd on mini devices yet?
i want something with low latency, audio output at least, but audio in/out even better.. the ability to connect some sort of sensors or controllers (even really basic stuff)
basically, i want to put pd in a guitar pedal.
any help?
cheap would be best, but i have a small budget i could use if a good option is not bargain basement.
i must also mention that i'm really not good at soldering, and my coding ability in anything other than PD is pretty shocking.
what options are there? i have heard of beagle board, does that work?
It's a current topic at the London hackspace. Im often thinking about new development boards that can run a decent guitar FX patch with usable latency on a playing card sized board costing less than a $50
Depends what you mean by mini devices though.
In theory a usable CPU only board would need USB, and a power supply, everything else, including LAN and audio can be added.
Most SBCs are actually very expensive dollar per cycle but there are some interesting possibilities

well, something like that raspberry or the beagleboard looks absolutely great, IF i can get one to run pd with just some really minimal patch.
the most important thing is low latency. i know how hard that is to get even on a 'proper' computer, so that's going to be the hard thing, yeah?
i don't mind if the device is a bit bigger. but you know...even these smart phones now can run pretty decent pd patches. surely there has to be some good option with dedicated audio in/out and low latency???
i can attempt a custom linux install even but i'd need some hand holding.

The basic arrangement is a real-time kernel and ALSA. If you can get those running you have a start. But very few people have any inclination to mess around at that level. Something like http://www.emdebian.org/ is often at the heart of a usable system.
Bear in mind that you have no hard drive. So a good idea is to make a live system. That means the whole system boots from a USB compressed filesystem and runs only in RAM. If you partition the USB stick and create a persistent home directory, then you have what behaves like a normal desktop. Except you won't want a desktop.
The bare bones are
Kernel core-utils, busybox ALSA telnet/ssh
With ssh you have a handle on the device, you can log in, transfer files using scp, remotely start and stop services. Try compiling a simple test program that produces a sine wave and get that coming out your audio device. Then see if you can get vanilla Pd on there. Note that if you go the Debian or Arch route you'll be able to use a package manager to pull a pre-built version for ARM very easily.
apt-get install puredata
This is high level guidance. Before getting stuck in see what some of the others say. I haven't played with this for a few months and it's a fast moving stream. There may be one or more off-the-shelf ways of getting Pd running on a small board ARM or intel, but you want a suitable kernel to try real-time guitar fx.

I did managed to run puredata on a beagleboard clone (igepv2) the audio IC on the beagle and clones is really bad, but with an external USB interface it works very well. I did tried a pitchshifter patch and ot worked. Better yet is to use LibPd. I also tried it using a puthon wrapper, amazing and super low resources.
Only problem. The ARM processors are diferent so you will need tocompile lots of externals from scratch. (Unless pd - extended start to have an ARM build system. No dia 31 de Out de 2011 12:02, "Andy Farnell" padawan12@obiwannabe.co.uk escreveu:

Hi Ricardo,
this is very encouraging news!
i don't need any externals, just basic pd. LibPd sounds like it would be ideal.
when you say about using beagelboard with an external audio device, is that hard to set up?
What is the latency like? i think i really need less than 20ms, but as low as possible is best.
It is not dificult to setup, provided that the usb device is supported by alsa/kernel. The latency depends greatly of the device cpu, kernel, driver etc. Low latencies like 4 ms seems to me hard to achieve. No dia 1 de Nov de 2011 13:07, "i go bananas" hard.off@gmail.com escreveu:
