"An unsung polysynth from the glory days of Akai still being an actual instrument manufacturer, the AX60 on the surface may seem like a Juno clone, but offers a very different sonic signature. Outside of being a six voice instrument with VCOs, the AX60 offers offers filter modulation from VCO2 for metallic FM effects. An additional feature of this instrument is the ability to use Akai samplers (S-612, S-700, X-7000, S-900 and S-950). Synth is in great condition with the exception of one missing slider cap."

"Rare Soviet synt for sale . WITH MiDi OUT ! Synt looks good and with own case . Fully functional . 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. ALTAIR-231 synth has fat and rich vintage analog sound with it`s own character and can be compared to 'MINIMOOG MODEL D' synthesizer."

Sound Semiconductor Announces Two New VCA Chips
"SOUND SEMICONDUCTOR SPINS OUT SINGLE AND DUAL VCA CHIPS

June 23, 2020 – Sonora, California – Sound Semiconductor today announced single and dual channel VCA additions to its product lineup, the ProCircuitTM SSI2161 and FatKeysTM SSI2162.
VCA’s – or Voltage Controlled Amplifiers – are used for automatic, remote, or CPU control of audio gain and/or attenuation in such systems as music synthesizers, dynamics processors, noise reduction systems, effects processors, and mix console fader automation; as well as design of voltage controlled filters, exponential voltage to current converters, and many other basic audio building blocks. Sound Semiconductor’s SSI2164, a low noise and distortion VCA with four independent channels, was introduced several years ago and has been embraced by the audio community.
In pursuit of even better performance, the newly launched SSI2161 internally parallels all four SSI2164 channels for a 6dB noise improvement, offering the lowest noise among VCA chips. Likewise, the SSI2162 internally parallels two pairs of SSI2164 channels for 3dB lower noise.
All VCA’s have exponential control with a –33mV/dB gain constant. Current inputs and outputs allow a wide range of input and output resistance to suit design needs, and a unique mode control permits selection of class A, AB, or intermediate biasing of the gain core to optimize noise versus distortion characteristics. A gain range from +20dB to –100dB is possible.
The SSI2161 and SSI2162 are both housed in a 10-lead Shrink Small Outline Package (SSOP). Pricing at 1000 pieces is $0.84 for the SSI2161 and $0.99 for the SSI2162. Both are available now.
Sound Semiconductor is composed of musicians and technologists with the goal of developing affordable, high-performance integrated circuits for music creation. For more information, please visit www.soundsemiconductor.com."
