This set of videos, via Ghost Money, captures a selection of pieces and demonstration for modular Mixtur-Trautonium, with Trautoniks, Doepfer, Analogue Systems and SynthTech modules.
The Trautonium is an electronic instrument that uses a wire controller to capture continuous pitch and pressure, allowing for vibrato and other types of expressive performance. This particular set up features dual ribbon controllers, controlling a modular synthesizer.
The next video takes a look at Oskar Sala’s Mixtur-Trautonium formant filters:
The filter was originally designed by Freidrich Trautwein as vacuum tube (or rohrentechnik) technology in 1930. The filters here are version of the design from the halbeiter, or semiconductor mixtur trautonium, dating from around 1989, and were made by Trautoniks.
The next pair of videos take a look at the Trautonium’s Subharmonic Generator:
Finally, here’s a performance video, by Ghost Money, of Meadow Clary:
