Hi, I’m Rudiger Meyer, a composer interested in the play between traditional concert music and new media. This site, my home on the web, is part documentation, part platform, and part experimental playground. It is also a place for writing – from notes & tweets to more extensive articles.

Modular Diary

I’ve packed the modified uLope sub-stages into a module that more closely resembles the ADBDR envelope in Hordijk’s Dual Envelope generator.

One of the innovations in his design lies in replacing the sustain section with second decay stage that can slowly taper off, thus allowing for more ‘natural’ sounding contours. With the decay knob turned all the way up, a conventional flat sustain can be achieved. The second decay is also preceded by a break setting that adjusts how far the first decay falls. The resulting shapes are perhaps most easily understood by taking a look at the diagrams in Hordijk’s schematic.

Each stage also has a modulation input that adds to the values set by the knobs. Since modulation is most effective when the pitch of the modulating waveform is lower than the one being modulated, a sample & hold has been included. Hordijk provides a nice explanation of this technique in one of his NOVARS tutorial videos.

The patch can be found on the Audulus forum.

Web Things

Branches of concert pieces created for the web:


First experiments in creating versions of concert pieces specially for the web. I’ve collected some of my thoughts on this in a few blog posts.
