Based on the legendary Leslie® 122 and 147, PSP L’otary is capable of reproducing as precisely as possible the classic sounds of those famous rotary speakers while also adding creative divergences from the original.

The PSP L’otary2, is our ultra high quality emulation of a rotary speaker (VST, AAX and RTAS for Windows; AudioUnit, VST, AAX and RTAS for Mac OSX). We based our algorithm upon two original and legendary models: the Leslie® 122 and 147, and spent hundreds of hours perfecting our simulations. In other words, this is not just another modulation effect! PSP L’otary is capable of reproducing as precisely as possible the classic sounds of those famous rotary speakers.

That said, the PSP L’otary2 is capable of creative divergences from the original. For example, you could set up both the rotating high frequency horn and the rotating low frequency drum independently from each other and emulate speakers with a static drum or even a broken horn or drum engine.




I just integrated the new PSP L’otary plug-in to the film score for the movie Chappie. It was a perfect blend of authentic and creatively flexible. It added so much to my mix. I even used it on percussion. Great new tool that does something that no other plugin I have does.

The PSP L'otary is so great that I'm thinking of selling my Model 120 Leslie. It's not only the best rotary sim, it's one of the best rotary cabinet sounds I've ever used. Amazing!

I have to say, I think PSP "nailed it" on the L'otary plug-in.  I've owned Hammonds and Leslies for years, including  the old 122 I've played a '51 C2 through on tons of records.  But these days, when so much is done "in the box", I've wanted a way to get the same sound with VIs  and recorded tracks. Now I can.  And the beauty is, you can run anything through it.  Organ, Wurly, Clapton style guitar, Lennon style vocals, synths,  pretty much anything you would want to hear through a real one, sounds great through L'otary.   I'm particularly impressed with both the realism and the adjust-ability included.  There's mike positions & distance, ambiance, ramp up and down speeds, amp types, crunch and distortion, and my favorite, a knob for bringing in the mechanical noise that a real one makes as motors turn and wind hits the microphones.  Awesome!

The new PSP L'otary - rotary cabinet simulator plug-in is the most authentic Leslie cabinet sound I've ever heard. I've used it as an insert on a track and also as an effect to send to a track. Either way, it has the sound and feel of having a real leslie cabinet in the room. The bar has been raised!

Wow, this new PSP L'otary plug-in is incredible, very subtle and real and can be used - as is - as a direct Leslie rotating horn replacement.  I should note this plugin is very sweet sounding, so depending on the microphones you would normally mic a physical studio Leslie with, you may want to post EQ slightly in the case of getting a slightly screechier top horn sounds that typical live performance PA SM57s give. Very real and a great sounding piece of software.  All in all, another "A" level plugin from the PSP VintageWarmer guys in Poland. Kudos!

I'm a B3 player from way back and I know the sound of a Leslie speaker intimately, so believe me when I say that the new PSP L'otary is the best Leslie simulator that I've come across. All PSP plugins are killer to begin with, but the company might have surpassed itself with this one.
