Note this is not an analog modeling synth like the AN1x but is rather has sample based oscillators.
"The second generation of the popular CS1x synthesizer is back in a bold and bright new Analog Modeling synth - the CS2x. Many new improvements and enhancements have been made. Polyphony has doubled to 64 voices and there's 16MB of sampled waveforms! There are 64 resonant 24dB filters! The Arpeggiator now holds 40 patterns for animating your sounds. All functions are MIDI capable, even the Arpeggiator can transmit its pattern data to other synths or sequencers! There is even a direct TO-HOST connector for direct hook-up to your computer..."
"The AN1x is a powerful retro-analog synth with a really cool new feature that lets you record real-time editing and filtering and be able to store it as part of the sound! A major contender in the new wave of analog-digital synths using DSP modeling of analog waveforms to recreate the coveted sounds of analog synths with modern digital specifications. It offers truly traditional yet modern methods of analog synthesizing, 10 notes of polyphony, 8 knobs for tweaking, and an arpeggiator with dozens of inspiring patterns!"
"This keyboard was inherited from a family member who kept this synth in BEAUTIFUL condition. There is hardly a scratch/scuff on the keyboard. Very light use with minimal signs of wear. *Please note* I am not a keyboard player by any means but I did turn it on and experienced a slight "wooshing" sound. Upon further research, I found out that ALL Multi-Trak keyboards suffered from a bad battery from the factory. BUT there are a few synth shops I called that said it would be no problem to replace the battery."
There is a relatively easy fix to prevent the battery from draining in the future as well.
"Korg vocoder VC-10 in near mint condition. This one has spend 35 years sitting in my smoke free home studio. Never gigged , used probably no more than 10 hours.
True collectors item , you will not find another in this condition, I still have the microphone original plastic."
I bought this synth refurbished about a month when it had 'its had all the signal path electrolytic capacitors replaced, a new 230v transformer (was originally 100V Japanese spec), and a couple of new potentiometers for the front panel controls.'
Cosmetically the synthesiser is in great clean condition just a few minor scuffs."
