Roland JV-2080
64 Voice Synthesizer Module (1997)

Updated version of Roland JV-1080 module keeping same waveform but adding for expansion slots, a bigger display, better effect DSP and some extra sounds onboard.

RACKMOUNT 2 rack units.Main panel features a 320 x 80 pixels display, 35 buttons, 2 knobs and 1 slots for DATA memory card - note that PCM card slot card from previous JV80/1080 has been removed.

Back panel terminal connectors:
- Midi interface
- main out
- 4 AUX assignable outs

Front panel terminal connectors:
- headphones.

 

 

SOUND main core cpu manages up to 64 voices polyphony or TONES- relative DAC is a 18 bits Burr Brown PCM 69AU.
STRUCTURE: a basic pacth is composed by 4 PCM tones samples with edit parameters:
- keyzone assignment
- pitch tuning
- panning position
- delay start time
- FXM oscillator crossmodulation.

 

WAVETABLE is a 8 Mb ROM contains 448 PCM at 16-bits waves, split into 2 main families:
- 193 PCM percussive and chromatic one-shot
- 255 PCM acoustic instruments.

 

EXPANSION Jv2080 is expandable using SRJ-V board (usual size is 4 or 8 MB) fitted in 1 of the 8 available slots. There are 21 SR-JV available with different instrument styles, here is the list:

SR-JV80-01 POP   SR-JV80-02 ORCHESTRAL   SR-JV80-03 PIANO   SR-JV80-04 VINTAGE SYNTH   SR-JV80-05 WORLD   SR-JV80-06 DANCE   SR-JV80-07 SUPER SOUND SET   SR-JV80-08 KEYBOARDS OF THE 60's & 70's   SR-JV80-09 SESSION   SR-JV80-10 BASS AND DRUM   SR-JV80-11 TECHNO COLLECTION   SR-JV80-12 HIP HOP   SR-JV80-13 VOCAL COLLECTION   SR-JV80-14 ASIAN   SR-JV80-15 SPECIAL FX Collection   SR-JV80-16 ORCHESTRAL II   SR-JV80-17 COUNTRY Collection   SR-JV80-18 LATIN Collection   SR-JV80-19 HOUSE Collection   SR-JV80-98 EXPERIENCE promotional board. SR-JV80-99 EXPERIENCE 2 promotional board.

 

STRUCTURE the tones can be combined in 10 structures (signalpaths) inspired from classic synthesizer D-50. These are pre-fixed audio patch that connects the 2 pair of tones into variable setups mixed with audio elements such as amplifier / filter and 2 digital processes:
- Booster amplifies the signal causing a distortion with new harmonics 18 levels of effectiveness
- Ring modulator.

PERFORMANCE the JV engine manages up 16 parts each with assignable:
- Midi channel assignment
- zone assign
- panning
- volume gain
- effect amount
- pitch tuning
A special GM (General MIDI) bank reads SMF Midi for a total compatibility.

 

 

FILTER it is the TVF - Time-Variant Filter - features 4 modes:
- lowpass
- bandpass
- highpass
- peaking (the "PKG" emphasizes frequencies around the cutoff value)
In addtion a filter keytrack function with +/- 200% harmonic content cutoff over octaves.

 

LFO there are 2 syncable delayed modulators fade-in/out time; they do provide 7 shapes with adjustable symmetries: triangle, sinewave, sawtooth, trapezoidal, random, sample-hold and chaos random.

 

ENVELOPE each TONE features 3 EGs:
- EG1 amplitude: 4 segments + 3 times, 8 velocity curves + key follows option
- EG2 filter : 4 segments + 4 times.
- EG3 pitch 4 segments + 4 times, keyfollow + random pitch

EFFECTS DSP is organized into 3 main sections:
- EFX: 40 inserts algorithms :overdrive, phaser, EQ, Leslie, tremolo, flanger, delay, and pitch-shifter
- Reverb: 7 classic algorithms (Hall, Room, delay, stage) with adjustable damp time
- Chorus: digital chorus has variable rate, pre-delay, feedback and depth.
The new 2080 FX DSP allows up to 3 EFX for each multitimbral part.

MEMORY:
- 768 ROM patches (128 are special GM/GM compatible bank )
- 64 ROM performance
- 128 RAM patches
- 32 RAM performances .
External media: it is possible to use 2 kinds of memory cards: model M-512 (32 performances + 128 patches + 2 rhythms sets) and common model M-256 (16 performance + 64 patches +1 rhythm set).
Battery replacement: classic lithium 3V CR2032 in battery holder.

 

 

EDITORS there are some free and commercial editors for Jv2080, generally they are the same used by 1080:

- Soundquest (MAC/PC $$)
- Jv1080 editor (MAX MSP beta)
- Changeit (old PC OS free)
- Jv1080 ED (atari st, free)

 

RELATED FAMILY:

	JV-1080 previous mode, same polyphony, structure, wavetable. Less expansion slots, different DAC, less presets. LISTEN TEST: JV1080 vs JV 2080
	XP-60 61 notes keyboard, quite same as 2080 with sequencer VIDEO
	XP-807 6 notes semi-weighted keyboard, quite same as 2080 with sequencer VIDEO
	JD-990 a cousin :) with very high sound quality but a different concept
