Re: [PD] Pd on a headless Raspberry Pi
Nope, I used a randomly generated sequence of notes made with phasors, ranging from 0 to 127 on the midi scale. Anyway, the quality of the analog output is not what concerns me here, since it sounds ok with aplay. The problem is that the same type of sound generated directly in Pd makes an awful lot of noise when i launch Pd at start-up, though it sounds ok on the hdmi output. Maybe it's something about the samplerate, no idea really. It's a pity that no real serious documentation exists on how the audio works (like the fact that the analog output is switched off when the hdmi in plugged in : is it in the hardware ? can it be configured to not work this way ?). I'll try an ask on the RPi forum. Nicorette is a brand that sells patches to stop smoking in France.

Re: [PD] Pd on a headless Raspberry Pi
Great thread, I join the list mainly to work on such a a project, it's quite exciting to think of having a portable programmable open source synth engine on the PI with a portable midi controller. I am working with the AKAI mini mpk, which has pad and keys and knob and nice feature like arpeggiator, sustain and program and prog change which is nice for such a small device. With the PI the alsa is in alpha development on the arm platform and therefor won't be at it's best for a little while. The floating point integration in the latest system made the audio a lot better, as on the first gen OS of the PI the audio was just impossible. I tried to play with chuck for a while, and it created a lot of audio garbage. I think it will be a hit and miss until the ALSA is stable enough sadly. I read also that using usb headphone made the sound even better, but I haven't tried that myself. For the HDMI out what did you use? A dac from the HDMI ? I am looking for a simple solution to convert the HDMI to analog whether as a DIY simple solution or a really small and portable interface that could be boxed with the PI.

well the analog output has been reported as being of inferior quality by a lot of folks in general as well as some on the PDlist. most recommended the HDMI audio out (you'd need a splitter cable) or possibly an external USB interface, but given the USB power issues lately reported by Pi owners i imagine that might cause further issues. scott On Tue, Aug 28, 2012 at 12:10 PM, Pierre Massat pimas...@gmail.com wrote: Hi all, I succesfully ran Pd on a headless Raspberry Pi (which is no big feat per se.

I've written a tutorial here : http://guitarextended.wordpress.com/2012/08/28/running-pd-on-a-headless-raspberry-pi/ ), but i'm getting a really heavily distorted sound from the analog output. No idea why... Any experience to share?

It sounds much better than Pd on the analog output. So it should be an issue with Pd itself. Perhaps it start to quickly. I dont know... just a short note: did you use a sine-sweep file for your test with aplay? Or something similar smooth and simple? I reckon the built-in PWM-output can handle complex sounds better than simple ones. I'm having some sort of deja-vu - didn't we discuss that some weeks ago? ;-) BTW, nicorette?? :-) Cheers, Pierre. 2012/8/28 m.e.grimm megr...@gmail.com hey pierre, what r u using for line-in? i have one of these: http://www.amazon.com/gp/product/B0069L9PZA/ref=oh_details_o04_s01_i01 but have not had the chance to try it. im curious what might be the best usb in/out for cheap. i also got this: http://www.amazon.com/gp/product/B005CLMJLU/ref=oh_details_o02_s00_i00 so i can ssh in on my local network (headless). although i have not tried it w/out the powered usb hub. just my own status update. m On Tue, Aug 28, 2012 at 3:10 PM, Pierre Massat pimas...@gmail.com wrote: Hi all, I succesfully ran Pd on a headless Raspberry Pi (which is no big feat per se.
