Katja Vetter

Katja VetterMorris Library, in conjunction with the organizations New Blankets and Openspace, is hosting Artist-in-Residence Katja Vetter from the Netherlands.

Katja comes from a background of carpentry, musical instrument making, and electronics.  She uses digital signal processing techniques including the open source programming language Puredata to analyze and manipulate acoustical sounds.

Come visit Katja during her stay at Morris Library.  She will be welcoming anyone that wants to come see her work, collaborate, or learn more about Puredata.  She will be located in the music studio on the 3rd floor of Morris Library, room 321.

Examples of some of her work can be seen on the tab labeled Katja's Work above.

What is Puredata?

Puredata is an open source visual programming language geared to musicians, visual artists, performers, researchers, and developers.  Created by Miller Puckette for interactive computer music and multimedia, it allows software to be created graphically without having to write lines of code.

Workshop Descriptions

Kaja will be delivering several workshops on PureData.  The workshops can be attended individually or as a series.  The theme is live sampling in PureData - real time capturing, processing, and playback using the PureData open source digital signal processing framework.

Slice//Jockey the App - Monday, September 29th: 2:00-4:00

Although Slice//Jockey is a program written in PureData, and as such is still fully editable into something else, it can be approached as a ready-to-use instrument and operated without any knowledge of PureData as a programming language and DSP framesork.  People use Slice//Jockey for live performances and some use it for tracks in composistions.  This workshop will introduce Slice//Jockey as a music tool, and explain its user interface which looks much like a memory game initially.

Under the Hood of Slice//Jockey - Tuesday, September 30th: 2:00-4:00

This workshop presents Slice//Jockey as a case study of a music tool written in PureData.  We will peek into its guts to see how it is built up from the ground using PureData's graphical objects.  The workshop illustrates how a highly personal software concept can be realized with the help of an open source tool and collaborative community.  References to online documentation, video tutorials, and lectures will be given for further investigation as a starting point for those considering designing their own music software.

DSP Routines in and Beyond Slice//Jockey - Wednesday, October 1: 2:00-4:00

Essentially, digital signal processing (DSP) audio effects are mathematical processes.  PureData is a programmable calculator for signals.  This workshop illustrates a few audio effects from this perspective, going a bit deeper behind the scenes of DSP programming (without pretending to be an engineering course).  This is intended as a session just for the curious.
