This is the famous sequence from the 1973 Pink Floyd Track “On the Run”. The melody sequenced here is © by the original writers and publishing company; covered here in the framework of fair use for educational purposes.
Play a 12th fret flageolet on the lower E string of a guitar (or 7th fret flageolet on the A string of a bass). Expression pedal controls filter frequency. Hold current preset footswitch to clear the feedback loop.
Disclaimer:
Most of my patches are made from scratch (some started from factory presets). Most require firmware 1.1 (or possibly higher). Most were programmed with an expression pedal hooked up to the LVX. So, if the preset does nothing or way too much, you may have to connect an expression pedal an experiment with pedal positions :-)
