Endless Undo: album release on clang


I’m very happy to announce my first solo release on the danish label clang.

playing with Benjamin @ elektrosmog


In June I’ve been in Mannheim again, playing a gig with Benjamin Brodbeck @ zeitraumexit. It’s good to see that the same crew (Flo&Volker) is still there and that their concert series “elektrosmog” is still happening.

Core Audio: a quick example using Extended Audio File Services


This post is more a reminder to myself: every now and then I keep running into Core Audio – and need to start all over again, cause I can hardly remember anything from the last encounter… Yes Core Audio is quite convoluted as it goes very deep, but it opens a lot of possibilities.

MaxMSP: Reduce CPU load by avoiding excessive GUI updates


In MaxMSP it’s very easy to create relatively good looking graphical user interfaces (GUIs) quickly, which no doubt can be very helpful in a lot of situations (user guidance, performance, teaching etc.). But it’s also true, that the display of (especially dynamic) graphics taxes the CPU quite a lot.

Most of the externals in my setup are from code that I wrote myself – so no big problem updating those. But one of the few externals from other people that i use is the famous sigmund~ object by Miller Puckette.

using vDSP_deq22 correctly


On a mac the Accelerate framework delivers a lot of very useful DSP functions. Most of them are pretty straight forward to use, some are a little complicated. One of those is vDSP_deq22 / vDSP_deq22D which implements a vectorized 2 pole 2 zero filter (biquad).

Flyer Art


I’m moving houses (again…) and while packing up my things I found this collection of old flyers in my drawer. As far as I know they were all handmade by Gilbi Trefzger (Smacks Tracks, Nuns n’ Hoses, Paris Safari), and even back then, I thought that they deserved a longer life time than just being […]
