[ANNOUNCE] DJster Autobus – Real-time pitch and rhythm generator

Mar 29 2012 | 7:13 pm

DJster Autobus is based on Clarence Barlow’s legacy real-time pitch and rhythm generator, originally running on the Atari ST computer. The device has 12 parameters which control various musical textures that encompass a wide range from tonal to atonal and from rhythmic to arhythmic structures, with strong allusions to historical and ethnic styles. The device reads text files containing the definitions of scales and meters and also opens .scl files from the scala library with well over 4000 different scales. The device improvises according to probability distributions – based on theoretical research performed by Barlow in the 1970′s – and uses a sound font player and/or a sampler for microtonal playback. Documentation for the original program is available at

Looks great, I can’t seem to find where the installer has put the .amxd though. A search for djster .amxd on my computer comes up with nothing.

Are you on Mac OS X Lion? In this case, you may need to make you Library folder visible. See
Then just look for DJster Autobus in the Max MIDI Effect/DJster folder. Please let me know whether this helps, or whether you’re on Windows after all.
