Features & Capabilities

Synth Super JX is an advanced subtractive synthesizer designed for musicians and producers seeking warm, analog-inspired tones. Featuring two oscillators, LFO, amplitude and filter envelopes, this synth provides rich sound-shaping capabilities. It supports MIDI control with dual MIDI drivers allowing connection of two keyboards or controllers simultaneously, including Bluetooth devices.

The synth offers polyphonic and mono modes, a 432Hz tuning option, octave transpose buttons, and zero latency performance for real-time playing. Users can explore 36 built-in voice patches, save custom patches, and import/export via System Exclusive (SysEx) messages. MIDI program change and continuous controllers (CC) enable detailed control over parameters like glide rate, oscillator mix, filter cutoff, envelope stages, reverb, delay, and more. With intuitive knob controls (double tap to reset) and a comprehensive preference menu, Synth Super JX is a powerful tool for expressive synthesis on Chrome.
