via this auction. Video of one previously posted here.

"One of the very first offerings from Kurzweil Music systems, when they were still located in Waltham, Massachusetts. This is the expanded "FS" (Fourier Synthesis) version of the K150. Besides being an early additive synthesizer, the K150 is notable for its implementation - a rack of 240 digital oscillators? 256-stage envelopes? MIDI velocity, polyphonic aftertouch, splits, layers and more? The MIDI implementation is more impressive than most modern instruments, and this was from 1986, when gear like the Juno106 were dealing with simple note on/off messages. It is utterly unlike anything else. Not a great general purpose box for all sundry tasks, but a programmers dream machine for those who desire to craft some sounds which could not be done with anything else. Unlike most digital synths (which lack low-end), the K150 is all low end. In fact, it cuts off around 8khz-10khz. You can play with the included presets for days, or hook up to an old Apple computer for full harmonic editing. Embrace this rare opportunity!"

hollydog68 Arp Quartet Demo pt.2




via this auction

"Has ARP label but is basically a re-branded Siel Orchestra. Limited production years, 1979-80 ….a four part analog orchestral synth with Brass, Strings, organ, and Piano. Polyphonic, fat sounds…nice Chorus effect on Strings is like an Arp Solina on the cheap ! Brass patch is especially fat and nice. all voices can be turned on at the same time for a nice layered sound.

All keys works, has all original slider caps, all voices work and sound as they should with the exception of..

Brass Sustain …makes the sound brighter but does not add sustain, and its LED does not light.

Has pop-up "stand" on bottom of case for playing on top of another keyboard....Case is okay for a 34 year old instrument…paint is crinkled in a small area on right of control panel, and there are some dings on the back. some chips in the wood side blocks.

To hear demos of this particular synth, i have posted YouTube clips with external reverb added….

It was manufacture on "Estradin" military radio plant in Zhitomir city in January 1987. The serial number of the unit -3700.

Condition

This auction synthesizer after full professional service and in really excellent working condition.

All electronics was checked and tuned. All old soviet capacitors was changed on good quality new. All potentiometers and switches was cleaned and works without any noise on mooving. Old soviet In/Out connectors was changed on good quality Amphenols. 3 Oscillators was fine tuned. Cheap original plastic sides was changed on great wooden. In two words the old machine reincarnated in new spaceship...

Altair has the same architecture as Minimoog model D and the sound is also very similar. But due to original soviet electronic parts it has it`s own unique character.

It has very fat and impressive analog sound with wide sound palette. It can produce fat analog basses, classic rock leads, hard razor waves, various space fx`s , noises, ambient textures etc... The filter is really extreme and sounds fantastic.

The set include >>> Altair 231 synthesizer + original volume pedal + set of main rare soviet chips used in the synth, that you can see on the last picture..."  Like little robots ready to explore.
