Re: Hi there, I need help to configure Ubuntustudio on my machine
I highly recommend qjackctl (see http://qjackctl.sourceforge.net/ ) for controlling the jack audio server. If you're running ubuntu studio it should be installed already. It makes starting/stopping/configuring the jack server much easier. Jack never runs on computer startup because it is designed to handle any audio needs from basic to extremely complex. It therfore has a bewildering array of options that take some time to figure out. That being said, qjackctl makes using jack about as painless as using such a complex piece of software can be.

I suggest you should begin your tests with the default settings and report the errors. Just: jackd -dalsa -dhw:Juli Cheers!

Summer Design Workshops 2012 using Embedded Ubuntu
Dear all, Come realize an exciting project of your own design at one of our summer workshops: • June 11-15, Satellite CCRMA: Interaction Design, STEIM, Amsterdam, Netherlands http://steim.org/event/ccrma-invention-embedded-instrument-design/ • July 16-20, New Music Controllers, CCRMA, Stanford University, USA https://ccrma.stanford.edu/workshops/new-music-controllers • July 23-27, Stompbox Design, CCRMA, Stanford University, USA https://ccrma.stanford.edu/workshops/stompbox-design The idea is basically that Beagle Board + Arduino + Your Design = Wow! Embedded linux makes new kinds of projects possible, including autonomous projects that are independent of the Internet. We teach you the basic principles of Physical Interaction Design to help guide your project's development. Depending on your interest, you can select a flavor of the workshop more oriented toward new musical instruments, sound art installations, or sound effects. The workshops are appropriate for artists with minimal knowledge of computers but who are interested in technology like Arduino, as well as makers, engineers, computer scientists, and product designers who are interested in exploring artistic outlets. Visit the links above for more information individually about the workshops. We are looking forward to welcoming you. If you have any questions, please contact me or the other instructors.
