Subseptance is a sound experiment by Pär Carlsson. With it, he delivers lush ambient music, most often written for (/with) a custom built instrument that makes use of 6 hospital infusions, dripping water at individual rates. Every time a drop is released from its tube it triggers a message that is sent to his computer in order to generate musical information in the form of midi data and randomization of parameters within Ableton.

To accomplish this he has developed a custom setup based around MAX/MSP and Ableton live. Because of the way the device is constructed, the rates of dripping will never be the same twice. This, in combination with the randomization happening in the Samplers and Synths, makes every performance of the pieces written with the instrument unique and never repeating.
