The Hammond in Yamaha is better, than you think - Scannervibrato in chorus mode

[1-man-band-berlin]

Yamaha has a vintage drawbar organ in the keyboards, that sounds like a Hammond. There is a vibrato and it sounds a bit like the scanner vibrato in the vibrato mode, no chorus function.
Now I was thinking, how the chorus function in a Hammond works, it is so, that it mixes the dry signal with the effect signal.
So I tried to do the same drawbar setting on 2 right parts, one of them with vibrato on in depth 2 and both without rotary. Wow, it's the scanner vibrato in chorus mode. Now on the dry part percussion and there is no need for a drawbar module.
It's possible to use rotary on this, didn't try yet. It could be, that 2 insert DSP with the same rotary may sound badly, for they aren't synchronized. I would try this or maybe rotary on the part only, where the vibrato is off.

I've been doing this ever since it was possible on a Yamaha!

The trick is to put exactly the same drawbar setting in Organ Flutes for R1 and R2. One has vibrato, the other doesn't. You can then balance the ratio between vibrato and non-vibrato to your preference. Some Hammond artistes had their B-3s modified so they could do this. The result is very similar to the Hammond Chorus Vibrato.

And you can then route them both through the rotary DSP effect of your choice, again making sure that the settings are identical for both DSPs. If you add reverb, again make sure it's identical for both. And you can try panning R1 and R2 slightly apart. It's not 'original', but it adds a little extra dimension that you might like.

Thank you andy G. as always very knowledgeable! I do play around
with Organ world on my Tyros, but I really haven't a clue what I'm doing! .
Have a great day.
