PSP L'otary2 is a master quality emulation of legendary rotary speakers.
PSPaudioware based the algorithm upon two original and legendary models: the Leslie 122 and 147, and spent hundreds of hours perfecting the 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'otary 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.
PSP L'otary is available for Windows and Mac OS X in VST, AU, AAX and RTAS plug-in formats.
