Dear friends,
as a former owner of an Hammond with Leslie cabinet, in the many keyboards I had, I always searched for a decent "rotary" effect.
I found an excellent effect on my Clavinova CVP309 (Rotary Speaker 5), enough intense, also featuring the gradual velocity change from slow to fast, and opposite.
Few days ago I got my new Genos, and I was quite disappointed for the "Vibrato" quality and intensity of Genos rotary effects.
But insisting in my search, I finally discovered that Genos still carries the effects from older keyboards, under the list "Legacy".
And I happily found that the beautifull "Rotary Speaker 5" is there! ....just the same.
Before to go to detailed procedure, I need to strongly advise to connect an expression pedal (as Yamaha FC7), to may really enjoy the beauty of the organ sounds, including Leslie effect.
I use the expression pedals also for other sounds, like pads, solo instruments (sax, trumpet, synth, ecc.), getting more realistic results (the velocity control does not get to the same level of control).
-Press Right1 button (only: mute Right 2 and 3)
-Just above, press Voice Select-Right1 (a page with all the main voices will appear)
-In the left part of this page, select the voices group "Organs"
-Select "Gospel Organs" (since this is a Voice of the "Organ flutes", you may personalize the sound at your test trough the 9 drawbars/sliders, also adding Percussion, if needed)
-On the right part of the pannel, press "Voice" button
-In the Voice page, press Effect
-Press the area of Right 1 (small square space above the send effect slide controller
-Press "Type"
-On the left side, "Category", scroll to page 2 and
-Press "Legacy" (is where the many effects from older keyboards are)
-On the right side, scroll "Type" till page 32
-Select "Rotary Speaker 5"
-go to mixer, and adjust volume of Righ1 (this effect boosts volume a lot)
-to switch from Slow to Fast, and opposite, use the dedicated button on the left pannel.
That's it.
Please consider that by using the 9 drawbars, you can make hundreds of different Hammond sounds, starting from the epic organ sound of "A whiter shade of pale" (drawbars volume: 6-8-8-6-0-0-0-0-0, with a nice Reverb).
Hope it will help.
Greetings from Roma
