You don't see these too often.  This was the beginning of Roland's Variphrase vocal synthesis technology.  When it first came out there it was a significant release as it introduced a new method of synthesis, however if I remember correctly there were various issues or bugs with the unit.  I forget what they were and if they were resolved.  If you know feel free to chime in.   The technology next made an appearance in Roland's VariOS rackmount module which was meant to be a chameleon of sorts.  You could load different engines in it including a Roland Jupiter-8 emulation, but rather than host all engines at the same time, it would turn into whatever you had loaded.

"Here is a 1972-'74 ARP Odyssey Mk1 Model 2800 vintage analog synth. It is in great condition, particularly given its age. I had this passed down to me recently. This synth is very, very clean inside. I replaced all the bushings and contacts, refelted, cleaned the keys, and most importantly took every single slider completely apart, cleaned the parts thoroughly and reassembled after a lube-up: the sliders all operate smoothly and without static. I am not a keyboardist, believe me, but I did sit down and put this synth through its paces using the presets from the manual .pdf online, and the functions all appear to work great, as I was able to evoke all of the varied sounds the patches prescribed- pretty incredible. Also seems to hold tune perfectly, which is a problem with some of these. One thing I will add is that at some point an extra hole was drilled at the back, I assume to add a jack for a CV controller mod, so if you decide to do this, some of the work's done for you. Secondly, my benefactor removed the little colored tips from the sliders. It's just a cosmetic thing- you can buy a set here on eBay for $35..."

Akai VX600 Vintage Synth

via this auction

"The VX600 is a unique and compact analog synthesizer produced by the sampler-meisters at Akai. It's a six-voice synth with two analog VCOs per voice. This will give you some pretty thick and rich analog bass, pads, strings and so on. A very flexible Modulation Matrix allows you to route waveforms from each of the VCOs through the various edit functions. There is a lowpass resonant filter, a highpass filter, two LFOs, three envelope generators, two external sound inputs and more.

The VX600's patch memory stores over 100 patches, each of which can contain key group splits, MIDI info and voice allocation. Add classic analog performance modes such as unison, stacked mono and a new six-part multitimbral mode and you've got yourself some thick and full analog sounds! Its MIDI implementation allows for seamless integration into any MIDI studio. Additionally, a dedicated connector jack allows direct connection to the EVI1000 and EWI1000 wind synthesizers and a 13-pin DIN connector gives six individual voice outputs. Quite a powerful little beast!"

A Patch A Day, No. 27

Published on Jun 4, 2013 hamiltonulmer·28 videos

"This patch is fundamentally about attenuating clocks to produce different intervals, and using the same clocks to control the movement form one pitch to the next.

Here, we have the same basic idea - Wogglebug sending a clock into the Clock Divider. But we are using the clock divider in a very particular way, patching out of the various divisions, and attenuating either through the DPO's EXPO knobs, through the Dual Index, and through the Maths channels 2 and 3. These attenuated clocks switch between 0V and whatever voltage is necessary to produce an interval.

In other words, each oscillator is moving between two pitches according to their clock source of choice.

I have the Graphic Sequencer also being clocked by the Clock Divider, and that voltage going out to various modulation sources on the Dixie, the DPO, and ch 1 of the Maths (the fourth oscillator).

All in all, a delightful patch, and an idea I'd like to explore more in the future."
