Flute of the Andes by Maggot Emperor - NL
Simple boring flute when played dry, but gets heavenly when some reverb is being added... I just felt the Condor flying through the Andes while playing the flute!
I just designed it by turning some knobs and pushing buttons in search for some high (lead) sound, so I don't know if every button parameter contributes to the sound, but I just didn't dare to change a knob after creating and saving it.
(audio preview is with external hall reverb - Zoom MS-70CDR).
