Isn't the crosstalk one of the things that give us "that" sound we all like?
OHF

There is a company doing just that, putting a T.G. and an AO-28 in a box
that hooks up to a midi keybosrd. I can't remember who the are.

Would not such a device use some sort of solid state keying between the TG
and the AO-28? I guess if you wanted it to really sound like a B3 you could
use 61 9 pole relays for keying. I can't see that solid state, computer
(MIDI) controlled keying would sound the same as key contacts, no key click
for starters!

Hi Chris,
I have an A-100 and I don't think I hear any key click at all. Of course, being 68, my hearing is not what it used to be, but the organ has been in the family since it was new and I don't recall any "key click" from my better hearing days. We do not have a Leslie on the A-100. Would that make the difference?

About the shielding with steel your right about that.How about a lower
grade
stainless steel that is magnetic,I think the material cost would be offset by
less
handling and no plating or paint either.The stainless may discolor but NO
rust
and can be polished for a show model.

Yes Yes please forgive me for bringing that up what was I thinking?

My L-100 definitely has one "HELL" of a key click. Especially if run with out
a leslie or some type of animation.

There is a website about this on the net punch in L-100 and you should
come
across it.It is an extensive modification but it does sound good.You can also
drop in
an upper manual in the lower manual position and get 9 main busses instead of
7.
OR find an M-3 instead which is a drawbar only spinet with B-3 guts.

Hi Laddie,
The attack characteristic or "key click" of the Hammond organ has long been
part of the Hammond sound loved by jazz and rock players. It's most
prominent when played through a Leslie on chorale, with a few drawbars and
percussion (try 888000000 + 3rd harmonic). The effect does depend on
playing style and registration used as well as the individual organ.

Some organs have louder keyclick than others. A Leslie will definatley
bring out more keyclick than the internal speakers or a tone cab. The
Hammond speakers do not reproduce the same high frequencies that the treble
driver in the Leslie does, so the Leslie has more pronounced keyclick.

Thanks Ron...

HA!!! Stainless might just be the ticket lad, We shall see!!

Two things Laddie - One, what Ron B said about the console speakers
being lower-fi than a leslie's horn driver, and one suggestion - Try C3
Vibrato, 8' only (008 000 000). That particular drawbar with the Chorus
Vibrato on (which peaks up the highs a bit) can keyclick dead a Palmetto
Bug at 20 paces.

Hello Old Guy,

Just thought you would like to know that Hammond used a soft magnetic
steel in the dividers and installed the dividers to isolate all the
tonewheels from the effects of each other. They also matched the 4 or
less tonewheels to be frequencies that are harmonically related so as to
keep each tone as pure as possible. I am not completely sure of this but
I also seem to remember that the wheels were milled not stamped.

Hammond had also gone to great lengths to reduce several other
undesirable effects in the finished tone of each tonewheel. One of which
is responsible for that dearly loved "key click" that the pros of the era
asked Hammond not to eliminate. A great trivia question is; Does anyone
know what components cause key click?

The complete story of the organs development over the years is indeed
quite interesting. One fact in the story is that the idea of producing a
tone in that manner was not new. Another great trivia question is: Where
did the idea came from or what it is based on? Let's make this a trivia
quiz. The first person or persons to give the right answer or both
answers gets a BIGGG ATABOY from me. You may send your answers direct to

Yep, we saw. Evidently, you didn't see the Guinness I uploaded for you!! Much praise have I heaped upon you for that info. As I posted previously, I've turned that info over to my attorney. He has a good patent attorney on staff who will be contacting H-S next week to see what can be worked out. Thanks for the concern.

Guys...did you see my post linking to the patent? Its still valid.
Please make sure you cover your backs on this one or you could get
yourselves into trouble if you want to market it:( I still think a
recon exchange scheme would be a better bet..safer and more viable.

Hello Chris:
Well, it must be the Leslie that I don't have.. I use that registration and like it but no clicks.
I am working on that Leslie...if I don't get outbid.

This is a trick question, right? I'll bet it has something to do
with the start/run switches.

Sorry. Seriously, it's the contacts in the manuals vs the point in
time when they actually hit the busbars.
The tonewheels are in a constant spin (hopefully) and randomly
phased at any given moment. When one presses a key down, it could be at
any point in the wave. If it's at a zero crossing point, there's no
click. If it hits at the very top of the wave, a big DC component is
added to the sound, and you get a big click. At any point in between,
the click is less. But - except for the one case of hitting the key on
the zero, you'll get some kinda DC click.

If you have only one drawbar pulled out, you have a greater chance
of hearing one of those big clicks than if you have more than one out.

Why?

1. The contacts don't all hit at once. Pull all of the db's out,
and extremely slowly press a key down. You'll hear the tones all appear
one by one the further you press down. The clicks from each tone will
tend to cancel each other out if you press the key down normally. Also -
the aggregate volume of all the tones is loud enough that you won't hear
the clicks - they are masked by all the other tones.

2. The 91 tones in the generator are in 'relative phase' to each
other, but never twice the same. Everytime the organ is started, this
relationship will be different. This is why the idea of an optical disc
with 91 sensors ain't gonna sound the same as a real TG. All octaves of
a given note will always be the same relative pitch apart, but the phase
between those wheels is going to be different anytime the tg is
disturbed. Each generator wheel is dancing to it's own beat, phase wise.
A disc would always have those relationships locked together.

The complete story of the organs development over the years is indeed
quite interesting. One fact in the story is that the idea of
producing a
tone in that manner was not new. Another great trivia question is:

Uh. No Need. Anybody who has access to the internet can/could/has found
these answers already.

The Cahill Teleharmonium. Interesting device. Kinda the late 1800's
equivalent to music on hold!

Practically every trivia question that has ever been asked or
thrown out has already been answered. The Hammond community has been
doing internet lists since early 94, and before that it was via a
newsletter. In all practicality, there really shouldn't be very many
questions regarding the hammond organ and leslie speaker anymore,
because all of the answers are up here somewhere.

But its always easier to get on a list and ask, I guess.

Hey Laddie, try playing very staccato and with the one drawbar and V/C3,
you should be able to hear it then, even through the internal speakers.
