SX1000 is a faithful emulation of the JEN SX1000, a vintage Italian synth released in 1978. The SX1000 was one of the earliest affordable analog synthesizers, designed for musicians seeking hands-on control without breaking the bank. We have carefully emulated the SX1000’s M110 chip, and also expanded its capabilities by adding features like polyphonic mode, a sub-oscillator (down to -3 octaves), and additional controls for legato modes. We’ve also integrated an arpeggiator borrowed from a vintage classic polysynth and enhanced the sonic possibilities with four effects featuring flexible routing. Available as AUv3 and Standalone.
