Portamento Time - Roland V-Combo VR-09 Workshop Manual

Understanding SYNTH Programming
The VR-09 Editor app reveals the complete structure of a VR-09
SYNTH sound. If you're familiar with synthesizer programming, it'll
all look familiar, as the sounds are built using a traditional subtractive
synthesis architecture.
If, however, you're new to synth programming, the following sections
explain how everything works.
The Anatomy of a SYNTH Sound
Each SYNTH sound in the VR-09 is made up of the combination of
as many as three "partials" playing together. Each partial contributes
some characteristic to the overall SYNTH sound.
Partial 1
Partial 2
Partial 3
There are controls that affect the individual partials, and controls that
affect the behavior of the overall SYNTH sound. Let's start on the first
SYNTH screen with settings that control the whole sound.

SYNTH Sound Control Area
Sound name
Value display
The SYNTH Sound Control area applies to the entire SYNTH sound. It
shows you the sound's name and category, and its Value display shows
you the current value of any parameter you adjust as you're adjusting
it. Here's what else is there and what it does.
Setting This parameter:
UNISON SW turns the Unison feature on and
off. Unison slightly detunes the
sound's partials to make the
sound bigger.
UNISON SIZE adjusts the amount of Unison
detuning.
MONO sets whether only single notes
can be played at a time, or
whether chords can be played.
PORTAMENTO turns Portamento on and off.
SW Portamento causes pitches
to glide from played note to
played note.
PORTAMENTO sets the speed of note-gliding.
