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.

SX1000's advantage is rating (5.0 vs 3.7) and ratings volume (10 vs 3). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
