Roland JV Master Class: The ABC’s of Editing Tones & Performances
AS SEEN IN KEYBOARD MAGAZINE
There’s a lot more to Roland’s JV series instruments than just playing the factory presets. If you’ve been playing
your JV synth for a few months now and you’re ready to take it to a deeper level, read on; in this article we’ll talk
about Tone layering, controller routings, setting up Performances for sequencing, and some little-known
parameters that can add new colors to your music.
The tips in this article are for the JV-80, JV-90, and JV-1000. While all these instruments are based upon the
same synthesizer engine and have basically the same parameter displays, the JV-90 and JV-1000 have very
similar front panels, while the original JV-80’s is slightly different. If there’s a difference in procedures, patch
numbers, or buttons, those for the JV-80 will follow in parentheses. However, it may be necessary for you to
consult your owner’s manual to find the display pages under discussion.
Most of these tips will apply to the rack-mounted JV-880 as well, but its front panel is naturally compacted, though
most of the parameters discussed can be accessed. The new JV-1080 is based on a more advanced processor,
and though many of these tips can be employed by it as well, the JV-1080’s panel and menus are significantly
different. The JV-30, JV-35, and JV-50 do not provide the user access to many of the parameters we’ll discuss.
Panel Tour
Before we get inside the JV, we need to be familiar with some important portions of the front panel. First, each of
these instruments has mode buttons - Performance, Patch, Rhythm, and V-EXP (Performance Play/Edit and
Patch Play/Edit) - that are used to select the current mode of operation. Each has eight buttons on the lower left
side and eight sliders, collectively known as the Edit Palette. As you press any of the Edit Palette buttons, the
respective parameter is called to the display, and the sliders can be used to edit its value. The Edit Palette buttons
will call different parameters depending upon which mode you’re in: Performance or Patch, Play or Edit, etc.
Also important is a set of eight Function buttons (different locations on each model) labeled tune, effects, control,
and so on. These buttons have multiple functions as well, depending upon which mode you’re in. Each is multi-
labeled with a pointer to its function in each mode (color-coded lines on the JV-80).
Finally, under each display are eight buttons. In Patch mode, these are the four Tone Switches and four Tone
Select buttons. In Performance, they are the eight Part Switches.
Architecture & Terminology
To make sure we’re all speaking the same language, let’s continue with an overview of JV terminology and the
basic synth architecture. We’ll begin with JV basics: Tones and Patches.
But first, just what does that word synthesizer mean? Let’s call it a device that uses electronics to create and
control sounds. JV synthesizers, like many others, create their sounds from digital recordings, usually referred to
as samples or waveforms, stored in ROM memory. Those waveforms can be controlled in pitch, loudness, and
frequency content, then combined to produce the sounds you hear when playing the keyboard.
How do the JV synths accomplish this? Each Patch you call up is a combination of from one to four Tones. Each
Tone is essentially a complete synthesizer voice. In a tone, one of the JV’s waveforms is processed by pitch
controls, an amplifier, a resonant filter, two LFOs, modulation routings, and effects. (See Appendix 1 — “Reading,
‘Riting, & Roland” — for definitions and explanations of Roland synthesizer terminology.) The ability to layer these
“mini-synthesizers” into Patches adds to the richness and realism of the sound.
At a higher level than the Patches reside the Performances. A Performance is a collection of seven Patches and a
Rhythm Kit. Each Patch is assigned to one of the Performance’s eight Parts, and can be layered, split across the
keyboard, or assigned to its own MIDI channel for sequencing applications. Performances also control the JV’s
MIDI master controller features.

Palette vs. Patch Editing
Call up Preset Patch A17, “MIDIed Grand.” The Tone Switches under the display light to indicate this Patch uses
Tones 1, 3, and 4.
