VOICE main (mask) CPU H8/532 (at IC9) part of manages up to 24 voices polyphony with a 16 bits DAC UPD6376GS.
A JV-30 tone is composed by one or various PCM multisample - internal samples cannot be really edited just like previous classic digital model Roland U-20.
WAVETABLE up Internal ROM (3 X IC) wavetable features 445 tones (317 GS + 128 drums) or samples at 16 bits resolution mainly derived from classic Roland Canvas SC-55. Each tone offers 8 variations presets ready to go, easily accessible from panel.JV sounds are organized in instruments families (eg: brass, piano, orchestral) mostly bread and butter sounds
PERFORMANCE system manages up to 16 parts each and some parameters:
- volume mix + effects send
- fat mode: stacks 2 voices and adds a panning position
- otave add 1 octave lower layer
- dual: 2 different tones on a layer
- split defines 2 zones for split play
- solo mode (monophonic)
- transpose: up to 12 tones
- panning position
classic resonant filter with single cutoff parameter.
a simple delayed vibrato modulation with 2 parameters:
- adjustable frequency rate
- depth amount
section features a simple ADR (attack / decay / release) for amplitude: not really articulated.
EFFECTS DSP offers 2 engines A-B:
- ENGINE A: 8 chorus models: classic, flanging and short delay
- ENGINE B: 8 reverb models: hall, plate, delay and room.
MIDI good implementation for its time: exclusives systems that can access to all in-deep edit parameters.
MAINTENANCE AND REPAIR typical issues are:
- old tact switches for the buttons, replacement is quite easy but involves soldering
- Display flickering, try to search for cold solder joint.
" An early digital JV machine limited to general Midi purposes, with limited sound edit. Today at cheap price, but probably with technical issues. "
- only GS structure
- limited sound edit
- good for GS canvas
