If your bag is dance, trance and rave then this Groovesynth may be all you need! It has been used by Astral and M83.

The all-important sound generator is a high-performance synthesizer offering 64-note polyphony. A rich array of parameters, including sharp filters and ADSR envelopes can be modified using the knobs on the panel to create your own sounds. The sound generator can also be used as a multitimbral sound module, providing up to eight parts.

The JX-305 contains 274 high-quality preset patterns for immediate use and 494 RPS patterns.

been optimized for dance music.

The JX-305 provides three key modes: single, dual, and split. It's ea.sy to divide the keyboard into left and right zones, which can play different sounds simultaneously, or you can layer two sounds for every note. You can construct a song in real time as you play, sim- ply by switching the playback patterns. During recording, you can switch the recording part to record non-stop.

The JX-305's internal memory by itself can contain approximately 75,000 notes (up to 200 patterns).

You can play back phrases simply by pressing a single key. This has a wide variety of uses, such as adding accents during a song, or playing an entire song using just RPS. Play quantize changes the groove in real time The JX-305 provides three types of play quantize: Grid, Shuffle and Groove. Simply by rotating a knob, you can produce your own "groove" in real time.

The JX-305 is designed for live performance, with features such as a mute button that lets you instantly silence the playback of a specific part or rhythm instrument, and a Real-Time Transpose function that lets you transpose during pattern playback. Of course, you can also move knobs during pattern playback to modify the sound in real time.
