Still excited after installation, I've just wildly improvised this "vintage" demo of IK Multimedia / IK Multimedia Italia "AmpliTube Leslie®".
You can use it to record in your DAW or to play live as I do in this video. Its sound is mind blowing!
Check this state-of-art plugin that recreates a the truly authentic sound of the legendary Leslie® amps and cabinets in the digital world: www.ikmultimedia.com/products/atleslie/
Tunes with backing track at 1:12 and 3:20 written by Dave Limina, taken from his book "Hammond Organ Complete" (© 2002 Berklee Press).
