Kawai SX-210

Kawai SX-210 Image

The Kawai SX-210 (also manufactured under the name of Teisco) was widely ignored when released back in 1983 and is actually quite an underrated synthesizer. The SX-210 uses DCOs (1 per voice) with traditional analog VCF (filter) and VCA envelope generators. It features 8-voice polyphony, a 4-voice mode using 2 DCO per voice, and a monophonic unison lead mode (8 stacked oscillators!!). The SX-210 certainly stacks up well against the more popular Roland Juno-60 and Korg Polysix synths.

Program changes are entered using a global "Increment" wheel sort of like those used on the Roland Alpha Juno series. Fortunately its implementation is much better on the SX-210 - just hit a parameter switch and adjust the dial to the desired value or effect. The downside is there are only 32 memory patches. The oscillator section offers 3 waveforms, a sub-osc and PWM control plus a noise generator. The low pass VCF (filter) has its own ADSR envelope generator. There's also a high pass filter. The LFO can modulate both DCO, VCF and VCA, all at the same time! It is also one of the only synths to feature both glissando and portamento.

The SX-210 is pretty rare, only a few thousand may have been made. This rarity and its capable sound quality make it a great find, but it won't replace the Roland Juno or Korg Poly synths.

I put my Sx 210 up on ebay tonight... I figure someone who really needs one should have it. Unlike me who happened into it.

I have one of these synths. I bought here in San Francisco about a month ago and I think it's sick. I have a Juno 106 as well and I definitely like the Kawai. It's sound isn't so played out like the Junos and it never will be because only like 6 of them are left.
