hi Jeffrey,
I ll try and post some pics next week. My setup is nothing special:
- a Dell laptop (core 2 duo, 1,6 Ghz, and 0,9 GB of RAM)
- an EMU 0404 usb soundcard
- Fedora 12 with a rt kernel, JACK and Pd-extended
- an electric guitar, and some custom foot controllers based on a cheap usb
gamepad.
I get about 5ms of latency, maybe 4.5. I don't do anything too fancy in Pd, because it needs to be playable (i play in a rock band), but i can process both my guitar and my voice in real time without dropouts (and i use some rather cpu-intensive patches, based on fft analysis and stuff). The only tricky thing i was faced with when trying to put this setup together was the output impedence of my soundcard, which had to match that of my amp's input (i bought a shure impedence matching transformer and it solved the problem).
Hope it helps.
Pierre

I would like to exclude my laptop from live performance, so to be able to upload my pd patch (or patches) to a device like the beagleboard seems perfect for my needs.
@Dan Wilcox - Where you able to build your setup? which one did you go for? how would you be using it (live processing, generation, or sampling,etc.?)
@Pierre Massat - Can you post pics or a video (with some performance maybe )of your setup?
Latency is an important issue of course so your thoughts on how to improve it would be greatly appreciated.

I will be working on a gumstix or beagleboard setup on the fall for robotcowboy http://www.robotcowboy.com/ and should have my embedded pd scripting/software environment and software available for download. I've found a number of guides on running Ubuntu on both of these platforms and would appreciate any info you have on compiling pd, etc.

Hello list,
Well i do have in mind some ideas i want to implement with pd/hardware, one of them is using a single board computer to run pd without GUI, just using some little lcd screen. Maybe using a beagle board, that features a ARM Cortex A8 that has some floating point support, with the NEON instruction SET(I will need to recompile Pd for that).
Other than that i can also post the Hardware/Setup i used on some performances.
The hardware list is : Computer - Dell Studio 1737 Audio Interface - Edirol FA-101 MIDI Foot controller - Behringer FCB1010 Bassoon bocal pickup a wireless send/receive from Sennheiser and sometimes I use external sensors, like the wiimote, or some others connected to an Arduino board.
Software side is:
OS: UbuntuStudio, Driver/sound server: Jack/FFADO and of course, Pd
I have a video of one of the performances, it was my first public performance using RT effects and using Pd, It is not very good, but I am looking forward to improve it.

What kind of documentation would you like? I can tell you about the hardware:
- Dell D520 Laptop with Intel Core2 Duo, with Fedora 12 and the Planet
CCRMA rt kernel.
- EMU 0404 USB soundcard (2 ins 2 outs)
- A small Shure transformer to turn the balanced output of the soundcard
into an unbalanced input for the amp.
- Foot controller made off the cheapest USB analog gamepad one can find
(I'd recommend going for a higher quality, though...)
I could send you some pictures of the controller, too. As i said before i doubt that my patch is written well enough for it to be worth sharing. Yet i'll always be there to help if someone wants to make his own.

It would be great to see some documentation of this setup so that others can learn from it. You might be interested in Pd on Android, iPhone, Maemo, etc. and other mobile devices. Mobile devices are getting quite powerful, and they are already small. Then you'd even have a battery powered setup ;)

Hello everyone!
There was a discussion not too long ago about suitability of Pd in a live context (off the "smoother audio" thread i think). I just wanted to say that i use Pd everytime i play a gig with my band as a super multi effects. I have never experienced any crash in Pd, and the sound is just excellent, and everybody keeps asking me what the hell are these pedals and this software and how the eff do i make all these sounds, and well, i just think this is the future. I m just hoping that sometime soon we'll have a piece of hardware that's small and powerful enough to run Pd in realtime and I'll have the perfect gear (perfect for me). Just wanted to share this.
Cheers!
