PSP L’otary a master quality emulation of legendary rotary speakers!

The PSP L’otary, is our ultra high quality emulation of a rotary speaker. 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’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.
