Teisco • SX-240
The SX-240 is a programmable polyphonic analog keyboard synthesizer with MIDI from Kawai. It was originally released under the Teisco brand-name. It is a well rounded analog synth with 2 DCOs (pulse, sawtooth and sub-osc), a lowpass filter with ADSR envelope, a flexible LFO, MIDI and 48 memory patches. In terms of patch editing, the SX-240 is very much like a Roland Alpha Juno or Moog Source which resort to using a dedicated data-wheel to edit the values of selected parameters when you edit sounds. It also has a built-in real-time 1500 note sequencer and chord memory. And the sequencer can be split into 8 separate 200 note songs, roughly. The SX-240 is cheaper and comparable to similar Sequential synthesizers from this time period like the SixTrak and the Prophet 600, but sound-wise, is not as popular or cool as them or any of the Roland synthesizers either.
sounding synth. (its really a matter of opinion though) also, when your not playing notes, it is much quieter / less noisy than the six trak. I have never needed a noise gate for the SX240, ALWAYS had to use one on the six trak.
so its still reasonably priced.
