I tend to agree with Craig on this, its not harmonic beating but an inherent artifact of the sim used (Vent) in Cal's clip. Sounds like close micing for sure but more over, its the inability of a digital simulator to create randomness. A real leslie has 2 stack motors, a cloth belt, an idler pulley and a mechanical spinning horn rotating on a rubber and steel washer sandwich with a film of oil in between the rotor bearing and the steel washer.. All these oscillate at random intervals meaning there is a lot of speeding up and slowing down going on amongst all those moving parts. This is what gives that Leslie ramp character. The fact that its all random plays a big part of the sound. So what I hear on Cal's clip is the rotor 'whoo-whoo" in fast is too perfect, is repetitive, reaches its maximum rotation in the exact same way and stays there at the exact same speed and sound, ramps down in the same predictable manner and therefore annoying to those that can perceive it. Guess we get what we wish for. Cloning means exactly that, exact duplicates. I had this same discussion with Steve Hayes some years ago when he made his monster Leslie, a rubber belt instead of cloth, with no idler pulley. I told Steve he had overlooked the randomness of the original system which made for an unnatural ramp up/down effect. The idler pulley acted like a clutch and even if serendipitous, added a pleasing character to a stock mechanical Leslie. The cloth belt would slip and stretch doing its own thing, now gone because of the rubber belt he used. Made his top rotor take off like helicopter. Steve said he would then retrofit his Leslie parts design as he realized he forgot the idler pulley and the rubber belt was overkill. Back to the Vent, I'm sure adding a randomness factor to that would take a lot more calculations. To its credit Neo got closer to it and kudos to the brains behind that but its not perfect and I'm sure they know this. So either you accept the Vent for what it is, a very portable hands-on tweakable device not sounding exactly like a true Leslie, or you haul a real Leslie to the gig. And then, not all Leslies are created equal.

Sorry guys but I call bullshit on this "I hear harmonic beating".. There is no harmonic beating on this recording. This ventilator is merely set on a pretty close mic setting which gives that pronounced "beating sound" but this is NOT harmonic beating, it's nothing more than a close mic setting.
