Where to begin? There's just so much. Synthcom's Europa Mod gives it an up-to-date and comprehensive MIDI implementation like you'd expect out of a synth today. All parameters are controllable via Continuous Controller or SysEx. Europa also features an extensive arpeggiator which will sync to MIDI clock with programmable clock divisors and rhythms, and has about 50 more playback variations than the JP-6's original Up, Down, Up/Down, and Down/Up. A Europacized Jupiter-6 is a thoroughly modern synth with a classic sound.
