m-audio transit on Ubuntu 12.04

I freshly installed Ubuntu 12.04 and the ubuntustudio meta package. To get the m-audio transit card working I followed my older post (m-audio transit and ubuntu linux), i.e. installing madfuload which comes in the repository and adjust the udev-rules. They do not work the way they come installed.

So I used the content from corrected-madfu-rules and saved it as /etc/udev/rules.d/41-madfuload.rules. The according file in /lib/udev/rules.d I left untouched. The “41” instead of “42” is there because it reads “…Pick a number higher than the rules you want to override, and yours will be used. …” in /etc/udev/rules.d/README.

Something hang on my machine when trying the outcome so I rebooted the machine, although this might not be necessary for everybody. After that the sound card works as it used to.

m-audio axiom 25 and linux

This is a short message  informing that I plugged a M-Audio Axiom 25 MIDI controller into the USB port and it was recognised immediately. Sooperlooper, Specimen, JackRack, Hydrogen… perfect. I didn’t yet figure out how the transport buttons work.  The manual is telling me weird stuff…

(as of Ubuntu 8.04, 2.6.24-23-rt)

eeepc as a linux audio workstation

A few days ago I told you about the first steps into using an eeepc as a real-time audio tool. jack runs up fine. I chose the internal audio card with the combination 48kHz,  256frames, 4buffers (which gives a latency of  21.3msec) and running on its  own  it doesn’t cough up any xrun.

I couldn’t get sooperlooper working yet. Sooperlooper works (see solution)! freqtweak works  (A nice little thing!), too.  Ardour works very nice, too. Sometimes the screen is a bit small for the whole window, but  I was using ardour a bit today and it wasn’t too much of  a hassle. Audacity is buggy (converting to mono + playing results in a segmentation fault).

I will try and find out about sooperlooper and audacity. Other programs and how an external audio card  connects  (I hope  my older posts will tell me what to do), a midi interface and all that will come up soon…

things to come

Since the last post it has been a while, but the blog is not dead! That concert drained a lot of energy, therefore the publishing had to wait. Back on track, at the moment I am working on new posts. If working out as planned, there will be

  • a follow-up to the “Introduction to Sooperlooper”,
  • some insights into sound generation with python
  • and hopefully good news about using ATOM powered platforms for making live music.

I know that most people think, only the fastest and the best computer is good for music generation. But music has been made on computers for many years by now. Actually, this ATOM cpu seems to be close to the performance of the 1.4GHz Centrino, with which I have made some very good experiences. So, what is more important in the end is the creativity of the musician rather then the capacity of the equipment.

I haven’t been able to find a working real-time kernel for an ATOM cpu and my efforts on compiling my own haven’t been very fruitful. But I’ll keep looking for it. Maybe one should launch something like a netbookRT.sourceforge project? Any comments/ideas?

a live looping concert with open source software only

So this is a comment on the first concert I did together with a friend, using live looping software (sooperlooper) and an effect program (creox) to connect a microphone. Well, to a cheap stereo audio interface (m-audio transit) which got its input from a little DJ mixer (as a preamp with band filters) which had the mic plugged in. The output of everything (the live voice and the loops) left through one stereo output into the master mixer. My friend entered into it with an electric bass guitar (with echo). A forty five minute “gig” without any major problems. I’ll tell you how I connected it, the problems I ran into and some tips and tricks.
