This video, via midierror, demos one of Arturia MiniBrute designer Yves Usson’s Five Mods That Will Totally Void Your Warranty.

The idea of the mod is to add a lever switch at the back of the MiniBrute that makes it possible to toggle between the normal vibrato range and an extended audio range. With the audio range, the vibrato turns into a FM modulator for the main oscillator. With this one can create bell sounds and other ‘crazy FM modulations’.

Usson has provided details on the mod – which will totally void your warranty – at his site.
