Hi,
@ Miller : I think it's Pd 43 something (I use 42 on my latptop and it look slightly different). Unfortunately the phase vocoder example doesn't work, I do get some sound out of it but only in small distant chunks. Even the pitchshifter example doesn't work. The reverb example does work though. Please note that I tried all of these with the ethernet cable plugged in, I think it was using a substantial share of the CPU.
@ Richie : I haven't tried the GPIO yet. I find it a bit frustrating when they say that audio input can be added easily through the GPIO. I don't think it's true. It would take a lot of hardware around a good ADC, plus I guess a custom driver. There aren't any DIY audio ADCs on the web that I know of, except a project by a German guy who builds ADCs and DACs frm scratch.
One thing I would like to know is how difficult it would be to run Pd on this machine at a very low level, with a very minimal OS (I know nothing about this kind of things). 700MHz is a lot I believe, considering that a lot of digital audio gear was available before this chips were affordable. I'm pretty sure that a standard digital multi-effects for instance doesn't need 700MHz at all. I've been dreaming of building this "Pd box" people have been talking about for many months now, and I can imagine what a revolution it would be if it was open source.
Cheers,
Pierre.

This is really excellent news! I haven't tried Raspbian yet. I will as soon as I have some time. Has anyone tried accessing the GPIO with Pd yet?
cheers

Thanks to whoever made this happen -- I think some of the credit goes to Guenter Geiger who packaged Pd for Debian. I'm curious - what version of Pd cane up? And can you run the phase vocoder (audio example (doc/3.audio.examples/I07.phase.vocoder.pd) ? That took $30,000 worth of hardware when I first got the equivalent patch running around 1994.

Dear List,
I'm happy to inform you (some of you may already know this) that PD
vanilla
works out of the box on my new raspberry pi running the standard
Raspbian
OS. A simple apt=get install worked like a charm, no need to tweek anything, I got the sound working right away. The method proposed by
TedbOt
recently doesn't seem to be necessary anymore. I'll try pd=extended sometime soon.
Cheers,
Pierre. Sent from my Raspberry Pi, hahaha !
