I have purchased the best Leslie simulator to ever hit the market and the best part is that I have adapted it the KN7000 drawbars. The sound is absolutely as good as this link.

Not only that, but the way I congured it, I am able to play other instruments and rythm at the same time.

Most arranger keyboards will send the organ section to "sub out", but not the drawbar section. The great KN7000 does, as follows.

Program Menue/Separate Out Setting/Mono X 2/Mono1-RH/Mono2-Left

Choose Digital Drawbars for each and turn off DSP or you will not hear anything. Using a Y mono cable, connect Sub Outs to an analog volume pedal and into a mixer channel. VOILA, a thrilling Leslie 122 sound through the drawbars. If you don't want to run the L and R1 through the Ventilator box, you can hit bypass, and play as usual. The rythm and R2 are going through the mains and are not affected.

You can Google "Ventilator Rotory" and come up with all kinds of information. It is imported from Germany at a cost of $450 to US.

I have tried all kinds of keyboards and Leslie sims, and nothing comes close to this.

hi Bernie , thanks so much for sharing the information on this leslie sound module .

i think from the video that it sounds very good .

i have to midi accordions one an Elka 83 which has 4number 1/4 inch outputs split ie
flutes , strings , solo voices & Bass .
I think that this instrument would connect up fairly easily .
My other midi accordion is a Concerto digital accordion and only has 2 number 1/4 inch outputs Audio 1 mono audio2 for (stereo sound )
don't know if that would work to just get the leslie effect on the organ sounds ?

regards ..Giovanni
