Leslie 147 Roto
HX Effects
Helix's Leslie 145 sounds excellent out of the box, but it is even better with some improvement. The adjustments I did with my preset focused on the more authentic behaviour of mechanical Leslie. The first area of focus was to separate the Drum and the Horn, as in actual units, they ramp up at different speeds and rotate in different tempos too. To do that, I have used two models of Leslie 145 in parallel and panned speaker blend 100% separate for both the drum and horn. According to the sources, the horn rotates faster than the drum; hence I chose speeds as follows: Horn fast - 6.8Hz, which equals to around 410 RPM - the fastest reported horn speed I was able to find information on online. Horn slow - 0.8Hz, around 48 RPM - very consistent reported horn speed in chorale mode. Drum fast - 5.7Hz (342RPM) - is the fast drum speed on the lowest spectrum. As mentioned above, the drum is usually slower but rarely that slow. I wanted to simulate a loose belt on the drum, which translates to a slower speed and ramp-up/down times. The reason to go with the slowest reported rate was to get a bit more 3D tonality - if you want to simulate a well-serviced Leslie, I recommend upping the fast drum speed to 6.6Hz, which equals 396 RPM. Drum slow speed is set at 0.6Hz (38 RPM) - again, to simulate a loose belt, and this is the slowest reported speed measured on the real thing I found, with 0.8Hz being the fastest. The ramp time is also set different for the horn and the drum. Horn ramps up/down reasonably quickly where the drum, due to the loosened belt and the fact that it is heavier (more inertia), doesn't change speed as promptly, so it catches up slower. Lastly - I have used a 180Hz low pass cut on the drum side to cut on a boominess and added a bit of reverb. The setup is set in the way where EXP1 controls the reverb mix in 25-50% (personal liking), and EXP2 flips between Fast (tremolo) and Slow (chorale) speed. I am using this preset on Helix Effects in FX-loop of a real amp only, but I'm sure you will be just fine to apply this setup to any product from the Helix family I hope you like it.
