by the way, since I've been abusing so much of the GUI to build me fancy interfaces, I can see how easily it can choke on its update and flood the CPU.
Now, could an external video card help on that? What is the issue?
I'm using a macbook air and I see that the video processor is built-in the CPU or something like that, hence no proper videocard. I figure the RPI has gotta be something like that.
So, does it mean a macbook pro or other laptop / computer with some badass video processor or card can run the patches better even with same clock?
thanks

me? guide? to what?
Anyway, regarding RPI, are these cheap soundcards being tested supposed to help in the CPU load?
I've testing some stuff with my audio card here on the macbook air, and it's a RME Multiface II (via PCI-Express Card) and it doesn't seem to affect so much the CPU load (as measured by pd's meter). I can see a better improvement on latency though.
So, regarding the RPI, is the concern only about the latency? And how much can a sound card help after all in any occasion/computer/systrem.

trying any of the cards from DealExtreme?
no no all. just the ones on amazon. i submit my receipts to the uni so they pay me back. the students can use what ever i get that doesnt work.
BTW. if you write a basic intro guide that a 1st or 2nd year student can follow (in english :)) ill use it in my class....

That's great, can't wait till you try them all, it'd be just too
expensive
for me to import them all and try here, so I'll wait for the winner.
Are you
trying any of the cards from DealExtreme?

i just tried a cheap-o mic but im assuming line-in would be the same no? i mean it was a passive mic so what the difference would be between that and a direct guitar line, for example, i do not know.
again, i ordered like 7 or 8 of these cheap-o line ins. ill test them as they get delivered and report back.
yes! i know of this http://elinux.org/RPi_VerifiedPeripherals#USB_Sound_Cards but not all of these test well with pd i am assuming by all the recent sound card crackling probs. also there are more that have not been tested or/and have been but not listed here im sure....

does it work for line input or just mic? thanks!

i just tested this card:
Logitech USB To 3.5mm Jack Audio Adapter ASIN: B0058P0I2C
http://www.amazon.com/gp/product/B0058P0I2C/ref=oh_details_o02_s00_i00
w/ dwc_otg.speed=1 in /boot/cmdline.txt
works between 10-20ms with no clicks with adc~ running various
patches
from manual (reverb, octave.divider, etc)
also works in conjunction with my edimax wifi adapter + vnc screensharing (no need for ethernet cable)
i added it and the beringer to the wiki. others should be added as discovered....
