"Antique Bridgeport organ which was digitally modified by Pro organ technician. Organ has now 61 semi weighted keys, every key is touch sensitive(you can control volume/brighteness by your playing fingers) All stops have numbers from 1 to 11(hard to see in video).By rotating first stop you can control volume, 2nd stop(push in) is power switch ON and OFF, 3rd stop is grand piano, 4th stop is electropiano1, 5th stop is electropiano2, 6th stop is organ 1, 7th stop is organ 2, 8th stop is strings, 9 and10 stops are harpsichords, 11th stop gives you variety of sounds. let's say if you push 3rd stop grand piano with 11 stop you'll get different sound of grand piano OR if you push in 8 stop strings and 11th stop you'll get vibraphone sound etc. The organ has 2 speakers, pedals on a bottom functions now as sustain pedal(right one, left one is locked). Organ also has MIDI IN and OUT, so you can use the organ as a controller or hook up other keyboard or computer. Under the hood is Yamaha NP series guts. Dimentions: 68" High, 48"wide including handles, 23" deep. Made in late 19' century."

"Customized Yamaha E70 organ into 2 and half Yamaha CS80: uppwe and lower keyboards are 2 polyphonic synths 2 OCS's per voice, 7 voices and monophonic synth with 2 OCS's per voice for bass pedal or extra keyboard. Same heart like CS80, same P.A.S.S. sound technology, same filter. Plus 7 individual outputs, inputs for sustain pedals, 2 general outputs. You can dual upper and lower synths + 2 organs. Sounds like CS80? yes, absolutely, it is CS80,but now it could be much bigger by mixing 2 synths and 2 organs together"
"...extremely rare vintage analog home type organ/synth Yamaha D85 in chopped condition. The organ came from original 1st owner. I bought one recently and it was modified into what You see now in the pictures, the organ weight is around 100lbs now( Yamaha YC-45 is 136lbs, CS80 242lbs). Yamaha D85 is basically model the E-70, top line at that time, made in 1977, with the addition of a rhythm sequencer, digital tempo readout, more rhythm variations, as well as Vocal and String Ensembles and 3rd keybed as a synth!!!. You can mix not only different waves, but You can mix keybeds. 3rd small keyboard has phenomenal synth sounds by itself plus AFTERTOUCH!!!, but if You mix with sounds of 2 orchestral presets and active orchestral waves... fattest I've ever heard. Also You can mix 2nd and lower keyboard in any possible way and even to add bass pedal orchestral sounds. D85 was top-of-the-line home console model that used Yamaha's "Pulsed Analog Synthesis System" (PASS) to create more lifelike sounding instruments. PASS took technology from the GX-1 and incorporated it into a consumer model instrument. The ramifications revolutionized the organ industry. Instruments voices began evolving towards emulating the true orchestral instruments rather than theater organ equivalents. Same technololy applied to Famous Yamaha CS80. Strings and voices beat ARP Solina and probably better then on CS80( I had one for a while)and of course much better than YC series including YC30 or YC 45D. Unit has also arpeggiator in 6 variations, sequencer, hold effect and tons of other feature included stupid drum machine. Yamaha D85 is certainly better than YC 45D and this particular one even weights less on 30lbs. I have to say sounds awesome, very rich and unique sound. Organ is practically is in very nice condition, everything looks fine and works fine. I hate to sell even this one, but I simply cannot afford to keep one at this moment. Besides chopping job and whole rewiring was not cheap at all. it's very rare vintage organ and it's hard to find one these days especially in great electronic and cosmetic chopped condition,You wil be shocked how good and sensitive aftertouch on organ and that's piece of history. which give you unique sound not buying Yamaha CS80 for $9000(I can't believe it!!!)"

Update via e man in the comments: "There is no CS style VCO, it's just the VCF's and VCA's - the VCO's in the electronic design are what's used to clock the waveform data from the basic waveforms in ROM. It's like the Korg DW series, only analog on the VCF/VCA side. It has very little pitch control other than minimal glide (semitone range) and same for the vibrato (if even)... the source oscillators are purely phase locked digital constructs."
And: "There is no analog VCO in this entire synth, certainly nothing resembling the CS80 or any other CS synth - zip, nada, zilch - anyone telling you otherwise is trying to sell you swamp water. This is a giant polyphonic that has much more in common with the Korg DW series (also having crude basic waveform in rom), but very much lacking in it's ability to do any pitch control - what little there is, is a an digital approximation of minimal range. The only place you could add modulation circuitry to any great effect is the VCF and VCA section of the Orchestra Voices - pitch modulation is either limited global vibrato or equally minimal vibrato on the upper manual via wiggling the keyboard that drives a photovoltaic shutter combo, again going to a digital interface having little effect - even the glide is minimal and digital. You will never get anything properly analog out of the the Wavetable oscillator end as it's a giant digital construct with loads of sample and holds to distribute the wavetable rom voltages that approximate the basic synth waveforms (ramp, pulse, square). It's basically 3 waveform samples in ROM with very little control over pitch other than basic notes (the speed that the sample is read out from the ROM)."
The following is the original post starting with the video description:
"Mystery is resolved. Chopped and completely electronically modified analog Yamaha E70 organ into Yamaha CS80 synthesizer. What You see now is 2 fully programmable polyphonic synths 2 OSC's per voice + fully programmable 2 OCS's per voice monophonic synth in a body of Yamaha E70. Same P.A.S.S sound technology, same analog filters and same sound, same offspring of legendary Yamaha GX1.
Any questions, please visit www.alvek.us"
"Here's one more organ from my collection: Yamaha E70 . What You see in the pictures is completely modified Yamaha E70 in body and electronically. Organ after chop work went 327lbs down to 130-140lbs(Yamaha CS80 is 242lbs) and under the hood all electronic carts are located pretty close to like inside of CS80. It's been a while people talking about E70 which has same P.A.S.S technology like CS80 and electronic carts, all wiring are practically the same like CS80. Yes, E70 has absolutely the same analog filters like CS80, same sound synthes and it does sound like CS80. This particular E70 has beed modified from organ into 2 and half fully programmable CS80. All presets still have same functions except FUNNYII preset green buttons. Those 3 green buttons(1 for upper, 1 for lower keyboard, 1 for pedal board or extra keyboard) function now differently. When You push FUNNY II E70 starts to work as most powerful and expensive programmable synth-Yamaha CS80. On left top of organ You see control box. The box has 3 sections: 1st for upper keyboard, 2nd for lower keyboard, 3rd for footpedal/or extra keyboard you can hook up. You can see all signs under the switches(3 waves forms sawtooth and 2 square waveshapes) and pots, they have same function like on CS80. So after all this E70 has 2 polyphonic 7 voices 2 OCSs per voice CS80 synths and one monophonic 2 OCS per note synth (pedal or extra keyboard which can be connected to E70 is monophonic, it's perfect for bass lines and pretty good even for leads as far as You will move 2 OCS slider from 16' up to 4'). Oscilators can be detunes between each other and between keyboard. Does E70 sound like CS80?. Yes, it does. Main different between E70 and CS80: no velocity and aftertouch on E70. Big flaw. On another hand You have 2 and half CS80 under the hood. You can build sound on upper keyboard and MIX IT with sound you built on lower keyboard. Also you can add organ/orchestral section(they all can be saved in memory-see small control panel on a botton of organ to left-very much the same look like on CS80) from upper keyboard AND organ/orchestral section from lower keyboard. Same thing can be done between lower polyphonic and monophonic keyboard/pedals: monosynth also can be played on first 2 octave of lower keyboard. Now You realize CS80 is kind of kind of behind! PLUS very powerful arpeggiator! and even cheesy drum machine and 100 lbs less. From control box You can see 3 cables coming inside of E70, each cable has 25 pins . The connector 9 pins in a middle of a back of E70 serves expression pedal. 3 inputs 1/4 on back are not hooked up. Could be 1/4main output(original main output on a bottom of organ)or sustain pedals-it's easy to hook up. Same about 6 inputs on control panel-they are not hooked up. It's your choice how to use them. I didn't connected any inputs for 1/4 jack, coz basically all extra functions are on control panel of organ. I don't play on stage, so I can turn on sustain effect simply by hand. The organ is absolutely stable in tune and doen't have overheat problems like CS80 Anyway, if you are still skeptical about what You read here, please check some INFO on line about unlocking Yamaha E70 and Yamaha CS80 both children of Yamaha GX1. And don't forget how much money you will save not buying CS80. Please check, read and watch all links below and You will see it's not a dream anymore. You can get 2 and half CS80 more than 4 times cheaper... compare to ebay price for last month. "
