Roland JV series

The Roland JV series is a line of PCM ROM sample-based (ROMpler) synthesizers, mostly in sound module form, produced by Roland from 1992 onwards. While containing similar underlying synthesis technology to the prosumer Roland Sound Canvas series, they target a more professional market, with most models being full-width rack units, and having a focus on high-quality, fully-editable multi-layer synth patches and expandability, and less of a focus on multitimbrality. Some units have basic General MIDI support, but in general not Roland GS support (see below).

It was succeeded by the Roland XV series, which replaced mono sample layers with stereo sample layers, and switched from 32kHz to 44.1kHz sampling.

Notable models:

• Roland JV-80 (first model, keyboard)
• Roland JV-880 (module version of the JV-80)
• Roland JV-1080 (most famous JV module)
• Roland JV-2080 (enhanced JV-2080)
• Roland JV-1010 (half-width, cost-reduced version of the JV-2080 with minimal panel controls and built-in Session expansion)

Very unusual models:

• Roland JV-50 and Roland JV-35 are JV-branded keyboards, but contain a Roland GS-compliant (approximately Roland SC-55) tone generator and therefore are radically different to other JV synths. They can however be upgraded with a VE-JV1 expansion board, which contains a normal JV tone generator.
