Triplex Classic

Classic FM sounds with a modern twist! Triplex Classic takes inspiration from famous digital synthesizers of the 80s and puts them in an easy-to-use, accessible interface. The synth engine was developed from the ground up to facilitate sounds ranging from pristine modern FM sounds to crunchy bit-crushed mayhem - with everything in between.

To try it out, get the Triplex Classic Demo.
