Hammond X-77 XTP-S

[ripz]

Does anyone know if there is a way (reasonably) to connect two Hammond XTP-S speakers to my Hammond X-77. I realize I may lose some special effects, but the main sound is what I am after.

If you do a bit of searching, you'll find that the general consensus is that the X77 only really works with its X77L. That's not to say that you can't bodge a connection to something else. But it can be a lot of hassle for little success.

Are you thinking of the small boxes that clipped into the XTP? I can't imagine them doing anything reasonable with an X77.

free set of XTP speakers on kijiji over here today, verted as a Leslie and a bass speaker lol

andyg,
I am looking at using 2 Leslies. One is a rotating bottom drum only and the other has a spinning top horn and rotating bottom drum. My other thought is using a 4 channel mixer to take the outputs from the X-77 and mix them to a amp. Any thoughts?

Andy is passionate about physical Leslies. I am not. I use a Hammond built stereo speaker simulator to make my vibrato.
x77 had a compllicated switching network to send flute sounds (sine waves) to the leslies, strings and reeds, not. IMHO. It takes some design work to replicate that. General consensus is that bass boesn't belong in leslies and complex waveforms don't either. Up to you, you're the designer.The separation was sone in the leslie cabinet on the X77, so a missing X77 leslie means some work.
X77 has a 96 tone geherator, and 10-11 drawbars and harmonics, which I love in my organs, H100's. You can make some complex waveforms with that. Unlike a divider organ where flutes and reeds are made on different boards and easily separated, X77's make the complex waveforms out of flutes and the only separation possilble is 0888000000 (flutes) on the top, 08765006732 etc (reeds) on the bottom manual.
X77's without a suffix had design problems of the wiring harness to the preamps, which allegedly caused hum. If I had one and couldn't fix the hum easily, I'd pitch the whole X77 transistor preamps, and run direct from the mixer transormers into a modern solid state mixer. Thence from the mixer, out to two or three power amps. pro mixers have "main" and "monitor" feeds, you can set different frequency curves, like bass cut, to the different outputs. The flat response output, you could sent through a graphic equalizer or sub cut filter to cut the treble and run a stationary bass only channel (woofer only) off of that.
As an experimental bed, an X77 could be a lot of fun. As a working organ, x77 without the suffix and without the leslies designed for it could be a problem.
Look up "x77 corner" or use the x-77 tag cloud for a lot more opinions from experts on X77's. I don't own one, the leslies run the cost and size up too high for me. H100's are $50=200 more in my price range.

X77 doesn't have strings or reeds, or complex waveforms, Indie, it's basically an H without its vibrato scanner, but with the X77L leslie. Drawbars only, plus Harp Sustain, which it also uses for its Arpeggiator.

Which model leslies are you thinking of? That would help a bit! What you've described could be any two of dozens of models. You could presumably take the 4 channels to a mixer and sum them for stereo amplification, but what are you then going to do for animation of the sound without vibrato or leslie?

Like I said,ripz, it's complicated and you should read through the existing threads like the X77 corner one that Indie mentioned.

, X77's make the complex waveforms out of flutes and the only separation possilble is 0888000000 (flutes) on the top, 08765006732 etc (reeds) on the bottom manual.

You make reeds on a Hammond tonewheel organ out of flutes. Don't know what hammond did in ths x77l to separate reeds, as they did in the next model Concord. That is why missing x77l is a problem. Possibly they just high cut the leslie input, but the schematics are not obvious.

[andyg]

They didn't. As the 'reeds' are only drawbar combinations they don't get routed anywhere else. The Concorde is a different ball game. It doesn't have any reeds either as such. It does have a percussion section with 'Second Voice', where the Harpsichord becomes a 'Violin' and the Banjo becomes an 'Oboe'. These voices are permanently routed through a stationary speaker, with the drawbars being routed through stationary or leslie, at the discretion of the player.

The only Hammond consoles of that era with proper reeds and strings were the G100 church organ, the X66 and the Regent theatre model. All the others had to fake the reeds with various drawbar combinations, as you know.

[kkeys]

Add an Elegante to the list of consoles with reeds and strings. Reeds on organ are both pipe and orchestral. No second voice tab needed for access and no derivation from drawbar harmonics.

[andyg]

Of course, but I did say "of that era". Elegante was a tad later. And it had more amplification channels to cope with all the non-drawbar sounds.

[kkeys]

Yes, the Elegante did come later than the Concorde. Since the Concorde is an LSI organ, my thought is the Concorde and Elegante are both from the LSI era.
