The JV-2080 ("2080") is a sample + synthesis synthesizer with support for 768 internal
patches, including General MIDI. In addition to the synthesizer, it also includes a multi-effects module, with 40 effect types, of which three can be used simultaneously. The 2080 is expandable via proprietary modules that contain both sample-based waveform data and patch information. The internal memory of the 2080 is divided into five sections. • USER – User re-writeable storage (RAM), initially contains a modified copy of PR-E. • PR-A, B, C, E (Preset A through C and E) – Presets in read-only memory, cannot be modified. • PR-D (General MIDI) – Presets compatible with the General MIDI system. • XP-A through H (Expansion A through H) – Patches and Rhythm Sets from expansion boards, installed in slots A through H. • CARD – Data from compatible memory cards and sound library cards (PN-JV80 series). The JV-2080 can also be 'stacked' with up to eight units ganged together to increase polyphony to achieve a 512 voice multitimbral performance. ==On-board demos==
