SuperSynthFX (SSFX) is a freeware software synthesizer and sample player designed with a focus on touch interaction. It offers an intuitive analog-style control surface optimized for use on Touch Panel PCs and Tablet PCs. Instead of relying on traditional mouse inputs, SSFX allows users to manipulate virtual sliders, buttons, and knobs using their fingers or a stylus, recreating the tactile experience of classic analog synthesizers. This design enhances creativity by making sound shaping a hands-on and natural process.

SSFX combines synthesis and sampling capabilities in a compact package, featuring a 48 MB sample library and 32 demo sound patches. The engine includes four oscillators and one wave player, each capable of handling multiple sample zones, with six-voice polyphony per oscillator and wave player. Users can explore an extensive range of modulation possibilities through four LFOs targeting various parameters, as well as cross- and ring-modulation between oscillators. The instrument also provides comprehensive envelope shaping with multiple ADSR modules and a dual filter section offering low-pass and high-pass filtering with resonance.

Beyond synthesis, SSFX integrates a versatile effects processor enabling simultaneous use of six effects including reverb, delay, flanger, phaser, chorus, and overdrive. This combination of sound design tools and touch-optimized control makes SSFX suitable for musicians seeking a hands-on approach to creating rich, dynamic sounds whether on a tablet or within a traditional DAW environment. Its free availability further encourages exploration and experimentation in sound design.
