Yamaha DGX 670 Leslie Simulator

A lot of people have been asking about the internal Leslie simulator on the DGX670.

I've made a quick video. Please visit YouTube link:

How do you turn this on?

If you have the (3) pedal unit (purchased separately), then the LEFT pedal will automatically be assigned to control Rotary Speed.

But, if you're only using a standard sustain pedal plugged into the AUX PEDAL input on the back of the DGX; then, you'll have to assign that pedal to control the Rotary fast/slow speed. Here's how to reassign the pedal function:

MENU -->CONTROLLER --->ENTER

On the screen you will see (4) rows labeled 1 Aux: xxxxx, 2 Right xxxxx, 3 Center xxxxx, 4 Left xxxxx.

#1 is the row that assigns what the pedal will function when you plug a pedal into AUX PEDAL input.

I'd you have the optional (3) pedal unit, then:
#2 is the row that you would assign what function the RIGHT pedal will control.
#3 is the row that you would assign what function the CENTER pedal will control
#4 is the row that you would assign what function the LEFT pedal will control.

On the bottom left-side of the window, you will see an up/down arrow above the number 1.

Those Up/Down buttons are used to scroll through the menu to decide what "function" you would like each of the 4 pedals to control.

On the bottom right-side of the window are up/down arrows to turn on/off the pedal for each of the PARTS (i.e. LEFT/MAIN/LAYER.)

NOW: to reassign your pedal from Sustain to Leslie Speed Control:

If you're only using a single standard pedal plugged into the AUX PEDAL input, then use the primary up/down/left/right pad (located below the MENU button) to scroll and highlight Row #1. "AUX: xxxxx"

Then, use the up/down arrows (bottom left-side of window) to choose the function: "MODULATION ALT".

Note: I realize that in the scroll menu, you will see a function called "Organ Rotary Slow/Fast". You would think that function would be the function that actually is used to control the Fast/Slow speed.....but on my DGX670, it doesn't....I have to use the function "MODULATION ALT". Maybe, your DGX670 has a different firmware and you actually use the function "Organ Rotary Slow/Fast" to control the Leslie speed. You'll just have to experiment and see what works for you.

Thanks so much for your quick and detailed reply. I only have a sustain pedal, but I’ll buy a 3-pedal unit and check this out.
Cheers!

Yea, adding the 3-pedal unit was a good purchase. Since the DGX doesn't have Modulation Wheel (only pitch wheel), the Center Pedal defaults to Modulation for all the synth voices. Very Cool. The Left Pedal defaults to Rotary Fast//slow and the Right Pedal defaults to Sustain. I use the AUX Pedal (4th Pedal) to be a floater-pedal that I can assign any function I want; And, all this is totally storable per Registration.

Later,
Joel

How did you make it. Can you have the leslie speed up and slow down realistically?

I'm not sure what you mean by, "how did you make it?" The rotor sim effect is already part of most of all the Organ voices. So, you don't have to insert any kind of rotary effect. But, in order to change the speed of the rotor, you have to assign the "fast/slow' speed to the Sustain pedal...OR if you got the optional 3-pedal system, you can assign the Fast/Slow speed to one of the three pedals and still have one of the pedals assigned to Sustain.

But, to answer your second question, the Leslie sim just goes from slow then straight fast and visa-versa. It's very odd and not really realistic when playing by itself. But, it sorta sounds much better when playing in a band setting.

As a follow-up to this rather old thread - mostly to keep track of discoveries I've made that may help others too...

I had better luck using "Organ Rotary Slow/Fast" on the Controller page (see screen capture), then using "Legacy DualRotSp1" for my DSP Type on an organ Voice (see multiple screen captures, including where I went into the "Detail" page.

In testing and experimenting, I noticed that when I pressed the Aux (4th) pedal the "Speed Control" on the Voice Set page would switch in real time between "Slow" and "Fast" to confirm that I set that up correctly, and that the speed would ramp up and down in proportion to the values in "Slow-Fast Time of Woofer" and "Slow-Fast Time of Horn to the speeds as set in the corresponding "Woofer Speed Slow" etc. I also saved my tweaked settings to a user voice for later retrieval and playback.

Hope this helps other newbies like me...
