STRUCTURE a basic patch is composed by 4 tones or PCM samples with indipendent parameters:
- keyzone assignment
- pitch tuning
- panning position
- delay start time
- FXM oscillator (crossmodulation)

 




editWAVETABLE
is a 8 Mb ROM (2x IC at 25 + 26) 448 PCM at 44,1 kHz / 16-bits waves

wavetable jv1080

The wave XP ROM is split into 2 main families:
- 193 PCM percussive and chromatic one-shot
- 255 PCM instruments

structure ALGORITHMS
the tones can be combined in 10 structures partially inspired from classic synthesizer Roland D50.

wavetable jv1080 click on pic for structure list.

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.



multitimbral PERFORMANCE the XP engine manages up 16 parts each with assignable:
- Midi channel assign
- zone assign
- stereo panning
- volume gain
- effect amount
- tuning pitch

TIP: A special GM (General MIDI) bank reads SMF Midi ensuring a total compatibility.



 


filter FILTER
the TVF Time-Variant Filter offers 4 modes:
- lowpass
- bandpass
- highpass
- peaking: PKG emphasizes frequencies around the cutoff value.
In addition a filter keytrack function with +/- 200% harmonic content cutoff over octaves-



Eg LFO there are 2 delayed and syncalble modulators, they do provide 7 shapes (triangle, sinewave, sawtooth, trapezoidal, 2 random modes and sample-hold) with adjustable symmetry.


lfo



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



FX EFFECTS the DSP is split in 3 sections:
- EFX: 40 inserts algorithms including distortion, 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 with variable rate, pre-delay, feedback and depth.


 

sequencer SEQUENCER quite similar to hardware MC-50 MkII, the xp50 manages up to 16 tracks at 96 clocks resolution per quarter note. Standard functions such as Overdub, Punch In-Out , Loop Parts, Quantizes and Copy-Paste.


sequencer

TIP: Internal tool load function imports old format from MRC sequencers such as MC-500/ 300/ 50/ 50mkII and Midi files in format SMF 0 or 1.




memroy MEMORY:
- 640 ROM patches (including GS MIDI kit)
- 96 ROM performances
- 128 RAM performances
- 32 RAM performances
- 100 patterns
- 20.000 notes
- 99 measures





memroy STORAGE
whole data memory can be saved to built-in 3.5" Disk drive Teac FD-235HF to either 720 Kb or 1.44 Mb density

disk drive
TIP: It is also possible to store SONGS made by sequencer for a maximum of 99 Songs (or 180.000 notes) on a single 1.44 Mb.

MAINTENANCE there are 2 common issues:

- LCD is well-known to have some technical troubles as the display writings disappear from the display, and this problem just get worst after a while! generally the nearby capacitors could have leaked and need replacement. There is a TUTORIAL about this, but I did personally replaced capacitors and it worked.

display replacement

 

- BUTTONS another frequent issues are contacts on the mainboard, tact switches need to be replaced soon or later as they get hard to push.

tact switch repair

 

mrmory EDITORS some computer-based patch softwares:
- Soundquest
(MAC/PC $$)
- JV-1080 editor (MAX MSP beta)
- Changeit (old PC OS free)

Should be a free release but I cannot figure this out. Surely NOT approved by Roland anyway, so it cannot be legally sold.
