"General Description :
The Kawai SX-210 (also manufactured under the brand name of Teisco) is probably one of the most underrated analog synths ever. Being a true analog machine and holding a set of features which many other single oscillator synths are missing, it is still a mystery why such a great instrument like the SX-210 has never been through the popularity of other equivalent synths like the Juno 60/106 and Polysix for example. Still it is quite rare as not many have been made.
The Kawai/Teisco SX-210 is basically an 8 voice single DCO synth based on the SSM2044 filter chips. It is generally very stable (as you might expect from it, being a DCO synth). The overall sound is very warm, yet not as fat as either the Junos or the poly Korgs.
On the other hand, it does feature an envelope for its filters, which you won't find on "basic" synths like the Juno 60/106. And it sounds like nothing else actually. I was able to nail that VCS3 "Welcome to the Machine" leads quite easily !
The SX-210 is also one of the first to feature an alpha dial, but not like most alpha dial based synths, you won't find any cumbersome menus to hate to deal with ;)
Instead, there is a switch for every function, and a small indicator to present the value for the switch selected. This is a great approach to implement, as you are still able to check into every parameter of a particular preset and read its current value !
The SX-210 is also 8 voice polyphonic, and can be used at 8 single voice, 4 dual voice and 1 eight voice configurations, which means you can stack all 8 oscillators into a one fat lead sound or a mega power chord lead ! Can you do that with your Juno ?! ;)
The LFO can oscillate the DCO section, VCF and VCA, all at the same time ! (use a Polysix and you'll have to decide which of the section you'd like to modulateן¿½ no simultaneous LFO action !) It is quite versatile and features a Reverse mode and 3 different waveforms plus a Trigger, as well as an LFO Delay and a Bender. Quite impressive for a single DCO synth, huh ?!
The single DCO section can do PW, PWM, SAW and Sub, and noise as well (non for the Polysixן¿½) The SX-210 also has a built in stereo Ensemble effect which is very rich sounding and will "widen up" just about any pad or a string preset very nicely, but I must admit it is not as warm as our well known Polysix Ensemble effect, and generally, far from being versatile as the Chorus/Phaser/Ensample Polysix section. The instrument could do wonders has it had the Polysix effect board ;)
Using the VCF modulation section (KCV / LFO / EG) it is possible to create some really interesting sounds. My SX-210 had two bad 4066 chips at the same place on two different voices, making the EG section going bad, only a few months separating between each incident. So this is where you should first look at when you're starting to experience strange EG behavior !"

A couple of new posts on the upcoming Moogseum are up on the Bob Moog Foundation blog.
* Several interactive instrument-based exhibits that will allow people the ability to experience the science behind the sound of electfonic music. We envision bays of Theremins hooked up to Moogerfoogers and rows of synthesizers hooked up to oscilloscopes filling our interactive area. A modular synthesis wall is planned as well.
