Hi Joanne,

The best Leslie rotary speaker emulation that I have found is UVI's Rotary:

https://www.uvi.net/rotary.html

It lists for $79 USD but it does go on sale.

This is fully adjustable and has presets for both instruments and vocals.

YMMV


I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
