Sound: Sophisticated fusion of a PCM synthesizer and COSM modeling sound generator
Sounds produced by a high-quality PCM synthesizer and a realistic COSM modeling sound generator can be freely
combined to take advantage of each method’s unique characteristics.
You can intuitively create new sound combinations with a high degree of freedom. For example, you could create a
new lead guitar sound that’s based on a standard distorted guitar combined with a synth lead or organ. Alternatively,
you might layer a ute or a synth bell sound with an acoustic guitar to create fantastic new tones.
COSM amps and various eects units are provided independently, allowing you to create an incredible variety
ranging, from raw guitar amp sounds to tricky noise sounds.
Expressiveness: Newly developed guitar pitch detection technology
The independent pickup signal from each of the six strings is analyzed at high speed by a newly developed
algorithm, ensuring quick and accurate response from the sound generator.
In addition, your picking position as well as the dierences between notes played with a pick or with your ngers are
also detected and transmitted to the sound generator, giving the GR-55 a range of performance expression that’s
much broader and more natural than any previous guitar synthesizer.
Easy use: Use SOUND STYLE to select a sound, and use EZ EDIT to edit it
The three SOUND STYLE buttons “LEAD,” “RHYTHM,” and “OTHER” provide performance-ready sounds in a wide range
of musical styles. A large-screen LCD ensures excellent visibility at your feet.
Press the [EZ EDIT] button to make easy graphical adjustments to the sound; this is a great convenience especially
when playing live.
What is the COSM?
Technology that simulates existing physical structures, materials, and the like using dierent, virtual means is called “modeling technology.”
COSM (Composite Object Sound Modeling) is a technical innovation from Roland that combines a number of such sound-modeling
technologies to create new and unique sounds.
