Delay Lama is free virtual synthesizer instrument plug-in for Windows and Mac.
Delay Lama makes your computer sound and look like a singing Tibetan monk. Delay Lama is the first software synthesizer that features both vocal synthesis and a real-time 3D animated interface, which dynamically reacts to musical gestures from the user.
To control the pitch and vowel sound (ooh-ow-ah-ayh-eeh), either a MIDI keyboard with pitchbender, or the built-in XY-controller can be used. For an extra mystical effect, Delay Lama has a simple stereo delay.
