Members alexstelsi Posted December 15, 2017 Members Share Posted December 15, 2017 Vintage Soviet Analog 3-VCO Synthesizer "ALTAIR-231" Up for sale is legendary, very rare & powerful soviet analog synthesizer "ALTAIR-231". It is a 3-OSC monophonic precise equivalent of infamous western MINIMOOG MODEL D, produced in the USSR in 1986 by Elektroizmeritel military factory in Zhitomir. Altair-231 is a refined version of another well-known soviet analog synthesizer Estradin-230. Both synths has identical electronic architecture, functionality and rich sound palette. Estradin-230 was manufactured from early to middle eighties and then Estradin factory changed synth`s design (new casing) and labelled it as "Altair-231". So Estradin-230 & Altair-231 are the same machines only in different bodies. Synth has 4-octave keyboard (F-C) with velocity (sensitivity assign to vibrato effect). For live performance there is a wheel which provides pitch shift. ALTAIR-231 is based on 3-VCO (OSC-3 can work as the modulator), 1 VCF (lowpass 24dB/oct) with ADSR, 1 VCA, 3 LFO, noise generator (white/pink), glide, memory. It has an EXTERNAL INPUT allowing to use FILTER and GENERATORS with OTHER INSTRUMENTS such as guitars, synths, etc! ALTAIR-231 consists of 5 main sections - OSC, MIXER, MODULATION, FILTER and AMP.ALTAIR-231 is one of the most impressive vintage Soviet synthesizers. It has inimitable peculiar sound and very powerful filters. A fat, lush and very analogue sound with the unique architecture of the Soviet-era components; in addition, highly reliable military technologies were applied in the process of production. The synthesizer is universal & may be used for hard electronic music, or for soft ambient/old school projects and for modeling various effects as well...endless possibilities (check the Demo section). ALTAIR-231 synth has fat and rich vintage analog sound with it`s own character and can be compared to "MINIMOOG MODEL D" synthesizer. +++ MIDI INTERFACE INSTALLED +++ The synth is in perfect working and cosmetic condition, fully refurbished & tested and works as it should. The mains power of the unit is universal: 110/127 to 220/240 volts. Device is RARE. In EXCELLENT working condition!
