Realistic Organ Chorus/Vibrato Effect

[hammondblues]

I am a new Fusion owner, and I thought I would share this trick I learned with everyone. I use a lot of organ patches with the band I play with, and I noticed that some of the factory preset organ patches lack choppy Chorus/Vibrato effect. If you combine the "Organ Rotary" effect with the standard "Rotary" effect, you can get a really cool choppy organ tone. You just set the standard "Rotary" effect at a high speed (low rotor rate: 3.039hz, depth 70%)(high rotor rate: 3.039hz, depth 75%). Use the standard "Rotary" effect in the Bus, and use the "Organ Rotary" as an insert. You can also set the level of the standard "Rotary" to the assign knobs if you like. When you set the "Organ Rotary" effect to fast, it sounds choppy, like the old Hammond's. I noticed that this trick works on the organ samples that were not recorded with vibrato/chorus or rotary on during original sampling. Give it a try, and tell me what you think. Thanks again to Hollow Sun and Alesis for all the wonderful sounds and patches you have come up with. Excellent work!!!

Thanks,

Ernie,
Welcome to the Club. That sounds like a good suggestion. Does that work because the Leslie speaker had a woofer and a tweeter that could travel at different speeds?

Thanks for sharing this, Ernie !

hey mps, the Hammond organ used a scanner type vibrato chorus that was attached to the tonewheel generator and spun at the same speed as the tonewheel motor. When you turned on the chorus/vibrato the audio was routed through the scanner, when you turned on the chorus (C1,C2,C3) it caused a choppy vibrato effect. If you used a Leslie cabinet, and you had a stop or brake feature which turned the rotors off, you could hear the choppy effect as it would be without the Leslie. If you listen to some older Santana with Tom Coster Sr. playing the Hammond organ, you will hear some really good use of the Chorus/Vibrato. At the end of "O ye como va" is one good example. It almost sounds like running two Leslies at once at tremolo speed.

Thanks for this tip! As I all so use a lot of organ sounds in my band and I don t allways cary my leslie with me.

And it all so works great with organ rotary combin with owerdrive rotary... I wont be needing more of new hammond sounds after all... Tnx for tip again!!!

I've recently tweaked -> created a set of hammond-oids on my Fusion. The factory program that I used as a departure point (sorry, too many edits, I no longer know what it was) used a chorus insert at 4.8 Hz to simulate hammond chorus going into the Leslie. I didn't like it.

Some of the old Hammonds simulated chorus by having the vibrato bend pitch only on half the drawbars, providing a feeling of motion-against-steadiness. So, that's what I did, like this: Let multisample 1 be the 888800000 voice. Multisample 2 was already pre-programmed for percussion. So I set up "high drawbars" (probably 000088888, but it's not specified) for multisample 3, and set up an LFO around 6 Hz to modulate the pitch of sample 3 only.

The end result provides a tolerable little wiggle in the higher harmonics, especially effective through a slow Leslie.

There's more to the patch, not really relevant to this thread. As soon as I figure out the little details of transferring it to my laptop and uploading to some web space provided by my ISP, I'll try to post the whole set of 7 organs with programming/playing notes, etc.

If you want a very good leslie without the hernia, have a look at this:
soundslive.co.uk/product.asp?id=4461

It gets great reviews and though I haven't got one I know someone who is over the moon with theirs. It models a 145 and a 112 including the valve overdrive.

And you can take advantage of the fusions aux outputs, programming your hammond sound to send to the aux instead of the main, and then only your hammond will go through the leslie sim. (That is a Steve from HS tip BTW)

I am actually pretty tempted by this thingie.

Nice suggestion. Can you please, if this does not disturb you, upload a preset with your changes ? or can you tell me please which program/samples do you use to apply your suggestion ??

Thank you very much in advance

Looking forward to see your programing Tom. Tnx.
