 Factory presets on the JX-8P were created by Eric Persing and Dan DeSouza.Though the JX-8P is relatively complex, it may appear otherwise for its lack of traditional synthesizer controls.It features two DCOs per voice, two software-generated (and relatively soft) ADSR envelopes, high- and low-pass filters, two types of (fixed-rate) chorus effect, three different sync modes, etc.
