Similar design to SX240 but one DCO/voice and no midi or sequencer. Digital control interface with analog filters. Funky sounding or nice more ethereal sounds/helicoptors etc. Decent strings though sweeter on SX240 in my opinion. Perhaps the ensemble is set up a bit different. Nice unit for quick/smooth editing in performance.
I went over the solder and cleaned up a little funky crackling on mine as I recall. Battery definitely should have been replaced by now. Any other known issues write me.
I should have many parts for these. Contact me if you need something.
