Re: [PD] [OT] Raspberry Pi Wolfson Audio Card
While I'm sure that Dan is right that the UDOO is the better choice for USB audio, I do have to say that I've had decent success using my Raspberry Pi as a guitar effects processor, with the Behringer UCG102 interface. There's definitely a lot of quirkiness to getting it running... for example ALSA gets in an infinite restart loop when attempting low latency on pd-extended, but vanilla starts up fine under the same settings. And then there's the fact that an issue in the kernel screws up USB audio on major distros like Raspbian. I'm using the Satellite CCRMA distro right now with much better success. So far I've got various delays, a looper, and a waveshaper distortion running within the same patch, at 20ms latency with very few noticeable dropouts. Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub.

Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub. Ultimately for one audio input the Raspberry Pi could probably serve most purposes, while the UDOO is more likely to scale to bigger installations. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- Rafael Vega email.r...@gmail.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] [OT] Raspberry Pi Wolfson Audio Card

Re: [PD] [OT] Raspberry Pi Wolfson Audio Card
Ok for small projects, but you're not going to interface a real stage mic or guitar easily. Would be much better if the next pi version comes with an onboard usb controller, which is the main problem for usb audio on the current pi. For now, the UDOO is where it's at for that.

Re: [PD] OT: raspberry pi
I would love to find that! i assume it's not an alsa thing since the HDMI audio is different. Hopefully someone here has already found this.

I got wheezy up and running and installed pd-extended. I could not get audio out of the headphone jack on the Pi, but it comes out of the monitor that has HDMI on it. I then of course got greedy and over-clocked it and corrupted the file system. grrr. I picked up a mini usb audio card a Soundblaster X-fi GO! Pro and in the boot screen it sees it and it's in the drop down menu for AUDIO SETTINGS but i cannot do anything after i select it and the whole system freezes.

For me what's worked best is to find a super-minimal install and then build requirements on top of that. With the project I'm working on atm I couldn't get my pmpd patch to even run with the standard install (there is quite a lot going on though). Now the patch runs fine with a whole heap of other stuff on top of that (2 sensors, 6 channel soundcard etc). My htop reading fills me with joy-I think there's about a dozen processes including 3 shells. As it's a rev1 board I built a system on top of the hexxeh image (same guy who's done the 'rpi-update' program for updating the firmware. My understanding though is that with rev2 boards don't do it. The one that I've been keeping my eye on, and they've just released a brand new version is Mobius http://moebiuslinux.sourceforge.net/ This is what I'll be testing out for my rev2 boards. There's a whole host of conflicting info re RPi's out there, particularly overclocking to squeeze every last morsel of goodness out of them. Us audio bods have specific needs - like I want mine running flat out all the time without blowing up and there's a big difference with that to someone who very occasionally pushes their RPi and wants to tell everyone that there way is the best. My own take has been to only use smaller cards (4gb) from reputable sources - very hit and miss though, very definitely YMMV This has been useful for tweaks: http://blog.extremeshok.com/archives/1081 Indispensable resources for audio: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=286064#p286064 http://wiki.linuxaudio.org/wiki/raspberrypi Don't do video so can't help on that front but my friend was just showing me his rpi xbmc setup which was really good so must be well-doable. And of course there's a ton of stuff on our lovely list.

GPIO sounds like a microcip PIC io port.

They can be easily added via the GPIO. So, still a possibility in an embedded openstomp-ish device.

Which has audio-in/out and gpio on a single plug. Combining that with a stompbox that holds, for instance, an msp430 (launchpad, by ti) with an lcd-screen and some nobs would make for a very nice interface :) Still looking in to compiling for their OS. The pandora is then again a very small niche, hence I was reflecting on the current interest towards the RasPi. However I didn't realize this device doesn't have line-in, so that indeed is a little discouraging. Alexander On Sun, Mar 4, 2012 at 6:15 PM, Ed Kelly morph_2...@yahoo.co.uk wrote: Hmm. Doesn't seem to have an audio input though, so perhaps it'll work for a synthesizer but not for a stompbox straight away. The site recommends a USB microphone for audio in, so that's not encouraging... Ed So what about a Raspberry Pi inside a stompbox that runs pd? But could the arm11 in that thing handle awesum (sic) audio processing? ;) Well the Raspberry Pi is based on an ARM chip. Does anyone know how these chips compare when running RJDJ or libPD applications? Perhaps this is a possibility, without too much modification of libPD or even RJDJ. ...but someone would need to write a host for the Raspberry Pi. What do you need by writing a host for Pd? Something like a very simple OS? Er..well I can see they run Linux, so I think I was mistaken. My head was in the world of BASIC - nostalgia gets in the way of the facts! Of course, Pd would need to be compiled for the hardware. I think we need to wait until one of us gets one and tries it out before we find out what they're capable of. I've expressed interest, but they're massively oversubscribed. I bought mine yesterday, and should receive it in about a week. The first thing I'll do is try to install Pd. On the other hand, the idea of a dedicated PDOS isn't a bad idea... Ed Yes, how hard would it be to have this? Well, it could be a highly stripped-down version of Linux. I don't think anyone has the time to write an OS, so I was being mischievous in suggesting this. I am having some funny ideas today... Ed Pierre. Even if it was just the PD core, it would enhance the educational scope of the Raspberry Pi - which is the whole point of this single-board computer (I learned my first programming on a Sinclair ZX Spectrum in the 1980s). I never thought I would see the day when the BBC Microcomputer would rule the world in telecommunications, but ARM chips and the ARM RISC instruction set are running every smartphone on the planet right now (correct me if I'm wrong :) and some of these smartphones run RJDJ and libPD really well. Dataflow music programming in schools. Maybe...
