Main Features
Versatile algorithms and
high-quality sound that
rivals dedicated professional
equipment
The VF-1 provides 46 effects, and 36 algorithms (effects
combinations).
A variety of simulations including preamp / speaker
simulators produced by COSM as well as a rich array of
effects such as reverb and chorus are provided.
It features 24 bit AD/DA conversion, and uses high-speed,
custom DPS to ensure quality that rivals expensive
professional equipment. It is a perfect match for any
instrument, and is ideal for use with any instrument, even for
serious recording efforts.
Algorithms and effect settings can be saved as patches.
In addition to 200 preset patches, the VF-1 allows you to
create 200 user patches.
Rapid searching by category
Each patch is classified by a category such as guitar or vocal,
etc. You can use the Category Search function to rapidly find
the desired patch. (p.19)
Graphic LCD
The front panel of the VF-1 features a graphic LCD for easy
and highly visual editing.
Quick setting
A preset setting is provided for each edit function. You can
easily create the desired effect sound simply by selecting the
preset setting for the function (effect) you wish to use. (p.26)
Guitar input jack
The front panel provides a high impedance input jack for
direct connection of an electric guitar. (p.12)
Built-in tuner function
The VF-1 contains a chromatic tuner function. (p.22)
Realtime parameter control
Parameters can be controlled from a foot switch or
expression pedal, or via MIDI messages. (p.33)
2-IN, 2-OUT
The VF-1 supports stereo input and output. You can apply
effects without impairing the stereo input image, or apply
two independent effects in parallel. (p.13)
Mountable in a 19-inch rack
A separately sold rack mount adapter (RAD-50) allows the
VF-1 to be mounted in a standard 19-inch rack.
Digital out connector
A coaxial type digital output is provided, allowing
connection to another digital device with no sacrifice in
audio quality. (p.127)
COSM (Composite Object Sound Modeling)
Once a musical instrument generates sound vibrations, it
reaches the human ear through various mediating
objects, each of which signi-ficantly affects the sound.
The material and configuration of the instrument, the
electric/electronic/magnetic amplifying system, the air
and the reverbration of the room all affect the final
sound. Sound modeling, the latest DSP technology,
"Virtually" reconstructs these objects. Roland's
breakthrough Composite Object Sound Modeling
(COSM) uses the advantages of multiple modeling
methods and succeeds in accurately emulating existing
sounds, as well as producing sounds that have never
before been created.
