Why is this not easy?
It's just pasting a few lines into ~/.asoundrc, and then
you're done... Pretty decent latency too. I'm pretty
sure this solution is generally the best.

Hello dear all.
Lately I've found this devices by APC that seem quite interesting to
me given my interest and projects around Raspberry PI and Linux Audio:
http://apc.io/products/rock/http://apc.io/products/8750a/
I love this presentation as a book,,
http://apc.io/products/paper/
... and that, presenting a device in a nice and not PC-like way, is
something I've been thinkinf of for a long time, but I couldn't do it
myself without a lot of building and DIY.
Does anybody have or tried one as it is? And with Linux?

hi folks,
i have a yamaha wx5 (midi saxophone). i was thinking to use my midi2usb
cable to plug into raspberry pi which would use some fluidsynth soundfonts
to synthesize music realtime.
do you know about such project existing, or should i work on it from
beginning? (i.e. find some rt kernel, install sw, rearrange system for no
gui etc...)
do you think raspberry can handle it well?
thank you.

Hi list,
I'm know this has been asked a thousand times already but could someone
please point me in the direction of instructions to enable non-jack
applications (like vlc) to work concurrently with jack? The well-known
situation is that jack "hogs" audio and makes other applications
unusable. How to get around this?
Many thanks,
Peter

I'm trying to compile (or otherwise obtain) the jackd utilities found
at http://rd.slavepianos.org/sw/rju/ , but I don't seem to be able to.
In particular, I'm interested in using the jack-osc tool to convert
jack transport messages (from Ardour) to osc messages. (Incidentally,
if anyone knows of another way of doing this, please let me know.)
Although the sources are there, I can't figure out how to compile them
- in fact I don't even know if they're in a compileable state. I tried
running make and playing around with gcc, but they seem to depend on
some files that aren't present there. I'm running Arch Linux, but
can't find a package for them in the AUR (Arch user repository).
Are these tools still current, or have they succumbed to bit rot? Does
anyone know how I might be able to compile them?
Thanks,

Hello LAD/LAU members:
I teach introduction to western music courses at a local
community college, and one thing I have to deal with is
students cheating by using a smart phone during the
exam. Sure, I am in the room and occasionally walk
down the aisles, but these enterprising students are still
often able to hide a smart phone from me.
The way these smart phone cheaters are usually caught
is when answering an essay question, they usually
look up the topic on Wikipedia and copy word for word
several sentences.
On these exams, there are a few audio identifications,
and recently one student did a surprising thing.
The audio example was from Pierrot Lunaire, and not only did
answer the question by writing down the title and composer but
she ALSO WROTE DOWN the title and composer of a track by Webern
which was on the original CD that I ripped the Schoenberg
from.
To summarize, from an mp3/ogg file that was put on-line
of one track from a CD, the student was able to identify
_other_ tracks from the CD that were not put on-line.
How did the student do this? Here are links to the two sound
files that the students had access to:
https://www.dropbox.com/s/66qkorouak19gpu/07_20th-pilu_p03_15-18.mp3https://www.dropbox.com/s/z17qoxey9ju4lei/07_20th-pilu_p03_15-18.ogg
Are there some tags embedded in these files? How would I
be able to see these tags myself?
If there are no embedded tags, how did this student obtain
this information?
Thanks;Â Ivan
Hi everybody
I’ve just stumbled on a very simple issue that I can’t solve.
Is there a simple command line player for JACK that plays .ogg files?
My first option would be the mplayer but it has got loads of dependencies and , as I’m working on a embedded device, I’d like to keep things as lean as possible.
Any help or suggestion is appreciated
Kind regards

actually, you are right Ben.
I intended to prepare RPi to use some external battery to play "on street",
or somewhere more mobile, instead of taking my precious VL70m synthesizer
all the time.
Thank you for reminder. You say "rapid stuff gets laggy", I will try it
anyway, using minimalistic raspbian and some performance tuning, but thank
you for your "kind warning", will keep it in mind. Will try to use some
more simple soundfonts (but probably not any "cheap" 8-bit like
synthesizers..)
Regards
Milan
