AudioThing has released an update to its faithful emulation of the JEN SX1000, a vintage Italian synth released in 1978.
Version 1.1 of SX1000 comes with support for macOS 26 Tahoe, new presets, and various improvements and fixes.
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.
SX1000 features
- Added: macOS 26 Tahoe support.
- Added: 5 new presets.
- Improved: MIDI Learn.

Regularly priced 69 USD/EUR, SX1000 is on sale for 39 USD/EUR at Plugin Boutique and from the AudioThing store until February 28th, 2026.
