 Hi,
 
 I want to experiment a bit with different tuning systems (temperaments) 
 so I was hoping I could find some software in which I could try some of 
 these, by either having some presets or by either indicating manually 
 the frequency for each note. By searching on Google I ended up on this 
 page (http://www.huygens-fokker.org/scala/), which seems exactly what 
 I'm looking for. Before I download/compile/read the manual/etc. does 
 anyone have a comment on this software or some other similar ones (if 
 they exist?).
 
 Thanks a lot,

If you connect the outputs of Rakarrak to the System playback_ 1  2 
can you hear your guitar? If not then check Setup in QJackCTL and try to

If you cannot hear your guitar, then your JACK configuration still isn't

is always the option of using an adapter to plug your guitar into the
microphone input on your sound card.  Not a GREAT solution, but it is a

It is likely a thermistor in line on the degaussing coil.

Flash Audio Issues

2010-11-30 Thread Tim Cook
Hi All,

I have a problem that I have not seen reported anywhere.  Maybe someone
here has a clue.

I installed Ubuntu Studio over Ubuntu 10.04 (AMD64)
Then upgraded to Ubuntu 10.10 

I am using an Alesis iO2 Express USB audio interface for my electric
guitar.

All of my apps and hardware work just fine for recording and playback.
Including apps that are not JACK aware (i.e. Sound Recorder, Skype).

The problem is with Flash apps.  It is not browser dependent.  Same
symptoms any browser.

For playback they generally work.  Occasionally I will lose audio on
video or just audio playback. Reloading the page sometimes fixes it.
Sometimes I have to restart the OS.  :-(

But one thing that doesn't work at all is my microphone (internal or
external) with flash such as Livemocha.com and others that I need  it
for professionally.  The flash apps see the microphone but I get no
audio to the app.  The situation is the same with or without the USB
audio interface plugged in. 

Any ideas at all on how to trace this down?

Thanks,
Tim

Mike,
I like this approach.  It is much easier to add things than it is to
take them away if they are in a meta-package.  There are several things
I do not and will never use.  But because of them being in the Ubuntu
Studio meta-package I can't (AFAIK) remove them.  

The work on the workflows and having them around for new users is great.
Then they can add what they need.  We can have workflows that
specifically say to install application XYZ in addition to UBS to
accomplish a specific task.

Thanks for all the hard work.

As an example though.  If I attempt to remove Gtick. Then Synaptic says
it will remove unbuntustudio-audio.  Not exactly what I want to do.  

Maybe it is because; I originally had Lucid installed then installed the

Re: Maverick and RT

2010-09-29 Thread Tim Cook
Hi All,

I am not trying to start a flame war.  Although I am a newbie here and
new to using real time kernels.  I am not new to computers (since 1976)
nor to open source (since 1994).  

As such, I think that I am in a position to say the below and I am *not*
picking on Jeremy.  He just happens to be the one that wrote this email.

If you are not in a position to be able to write code etc.  Then there
are a ton of other things you can do to help. Actively recruit on other
mailing lists for people to help out the author.  I see college students
all the time looking for projects like this on the Google Summer of Code
mailing lists.  Help Alessio put together a project plan and specific
tasks that will interest the GSoC team so the project gets accepted in
next years list.  

Cash incentives may or may not be interesting to Alessio. But think
about this.  If you, like Jeremy, *cannot work* without realtime
support.  Then what is the benefit of this project worth to you?
Probably a great deal.  Pool some users together and come up with some
money.  Your alternative(s) are what?  Probably spending lots of cash on
proprietary solutions.  If a group of you cannot come up with enough
cash to make it interesting for Alessio then you can probably hire a
couple of college undergrads that love music and love computer science.
Pay them to accomplish certain tasks as laid out by Alessio. Or to fix
certain bugs or add enhancements you want.  

My point is that there are a number of ways to help.  Remember that
Alessio's time has value.  Depending on your perspective it has
different values for each of us.  This is not a capitalist community.
But you need to look inside yourself and see if yo are contributing to
the betterment of the community or just living off of it. 

This is kind of a rhetorical email.  As I  said, it isn't meant to pick
on anyone.  In fact, it isn't even helpful to discuss the abilities of
any individual to contribute.  It is best if you decide how and what you
can contribute.  But, contribute you must.  otherwise these types of
project do not continue. 

Have a great day all.  

Cheers,
Tim

 Hello all,
 
 I might be able to help out testing and once I become confident enough
 with packaging I could help with some of the other aspects of
 maintaining a kernel. It would be great if a real-time kernel would be
 available for 11.04 again, which depends of course if there will be a
 real-time patchset available for the kernel 11.04 will ship with. Afaik
 the current RT patchset maintainer is Thomas Gleixner.
 But I'd like to stress that I MIGHT be able to help out, it also depends
 if other people want to participate and if I have enough time (I am
 before all an active musician).
 
 Speaking for myself, I can't work without a real-time kernel. I need the
 tasklet API that a real-time kernel provides so I can use rtirq. Without
 rtirq my FireWire devices don't work properly at low latencies or don't
 work at all. And even on systems that run well without a real-time
 kernel I prefer using such a kernel so that I can get the best
 performance out of my systems.
 
 Best,
 
 Jeremy

Seems to me that Ardour (or maybe even Audacity) would allow you to do
this.  I play my guitar into Ardour using pre-recorded play alongs or
backing tracks and it works great.  

So if you have a Vocals input and import your karaoke tracks; when you
start Ardour you start singing. You should be able to use JACK to route
the Ardour master channels to your server input. ???

I am not sure what you mean by live tracks.  Are you using a live band?

Actually I took the time to look it up myself (cat /boot/grub/grub.cfg)
and found that I have both the -rt kernel and the -preempt kernel
installed.  However, the last time I did any editing in GRUB was before
GRUB 2.x  In GRUB 2.x you have to edit /etc/default/grub NOT the
grub.cfg file.

http://ubuntuforums.org/showthread.php?t=1195275 

So I found now GRUB looks for a SHIFT key held down during the delay
period (default = 10 secs. )  so now I will checkout using each of the
kernels to see if I can get rid of the few xruns I have. Which is only
about 20 / hour on the generic kernel but I am running 256 frames/period
and 3 periods/buffer.

Well, I did some experimenting today and maybe I do not have the

Ardour with the same simple project.  In both cases; 2.6.32-25-preempt 
2.6.31-11-rt Ubuntu SMP  x86_64 GNU/Linux were worse at creating xruns
than the generic kernel.  Now I *know* this is nonsensical however I do
not know of another way to test to see which kernel I should be booting.

I also need the machine for email and web browsing. There seemed to be
very little if any performance differences in those categories between
the various kernels.  But this is subjective and not verified in any
quantitative manner.

Thoughts?

Amateurs ???

2010-09-25 Thread Tim Cook
Hi All,

This seems to be a fairly low volume list.

I am wondering if there are other amateurs like myself using
UbuntuStudio?

I just picked up a guitar again after not playing for 30 years.  I
wanted to start learning to play Blues properly.  In order to track my
progress I wanted to make recordings of my practices.

I started with Audacity on Ubuntu 10.04, Inspiron Laptop with 4GB of
RAM.  Audacity does way more than I need but as I started learning about
using the real time kernel I found UbuntuStudio and decided to give it a
shot.  

Now I am having as much fun playing with the recording and effects tools
as I am playing guitar. 

I bought the Alesis iO2 Express USB interface and after a bit of a
learning curve on setting it up it works great with JACK and Ardour.   

There are so many great tools to use I hope I can at least provide some
feedback for all the hard working developers on these projects.

As an open source developer myself.  I know I like to hear that people
are getting some benefit from the work.  Thanks to those developers for
such an awesome set of apps.


Cheers,
Tim
