The Roland XV-5080 128-Voice Synthesizer Module is the ultimate sound module based on the best-sounding, most expressive and expandable new synthesizer/sample player architecture in Roland history. With a massive 128 voices, the it is capable of extensive layering and multitimbral applications! There are true stereo waveforms per tone, expressive Matrix Control, expandability via 4 expansion slots for 64MB SRX-series waveboards (when converted into 16-bit linear format) and four SR-JV80 expansion slots. The sounds include those from the JV-2080 plus many more new sounds and waveforms from the JD-990 and Super JD.Packed with the most professional features you can find in a synthesizer, the XV-5080 has plenty of quality built-in digital effects including reverb and effects derived from Roland SRV-3030, V-Studios, and RSS technology. There is an R-Bus port which provides eight-channel 24-bit digital output to other R-Bus devices as well as an S/PDIF digital output! The XV-5080 is compatible with Roland S-700 and Akai S1000 CD-ROMs via its SCSI port. The sample-memory can be expanded up to 128MB, allowing you to load, edit and playback sounds from these libraries!Programming the XV-5080 is in-depth but intuitive and well documented. There"s a Patch Finder for quickly finding sounds sorted by type, as found on the JV-2080. Programming the new Matrix Control gives sounds an unprecedented level of nuance! The XV-3080 is almost identical to the XV-5080. The XV-3080 does not have the ability to read and playback Akai or S-700 sample libraries. The 3080 does not have digital output. It also lacks the COSM effects processor. The XV-3080 only has a 2-line LCD display screen whereas the XV-5080 has a giant JV-2080 style LCD display. Minus these few limitations, the XV-3080 is still an immensely powerful pro-quality sound module. But for the most professional and elegant Roland synthesizer ever, look no further than the XV-5080.
