Owner's Manual
The V-Synth XT comes with the VC-1 and VC-2 titles from Roland's "V-Card" software series preinstalled. Without having to cycle power to the unit, you can simply press a single switch to transform the V-Synth XT into a completely different product.
VC-1 “D-50” transforms the V-Synth XT into a sound module that's equivalent to the Roland D-50 (a classic digital synthesizer that was released in 1987). Not just the preset patches, but every bit of functionality has been faithfully reproduced, giving you that distinctive D-50 sound with the stability of modern hardware.

Main Features
Perfect Simulation of the D-50's Tones!
The VC-1 comes complete with all 64 of the D-50's preset patches, including the famous preset tones "Fantasia" and "Digital Native Dance." It also is programmed with the D-50/D-550 sound libraries PN-D50-01-04 (with 256 patches). Since it naturally handles MIDI bulk dumps, you can use the VC-1 to create your own original tunes exactly as you would with your D-50. Of course, this gives you a perfect simulation of the D-50's tones, from the sound generator algorithms to editing of the parameters! It even reproduces the subtle nuances obtained when playing the instrument.

In addition, it also comes with an additional 64 new patches, which use waves (28 types) that are so large that the original D-50 would have been technologically incapable of containing them.)
All sound generator parameters are assignable to the V-Synth XT's full complement of editing controls. Parameters can also be edited with the touch panel, allowing you to almost instantly turn your creative inspirations (no matter how fleeting) into sounds you can use. Whether the fun of creating sounds or pleasure of performing, this far outdoes the original.
Pro Spec Legacy Synthesizer!
Internal processing upgraded with the latest technology vastly improves the response and dynamic range from the time you press the keys to the moment the sounds are played. The V-Synth XT hardware is used as the means of outputting sounds, which means it's also compatible with digital outputs (optical/coaxial). This gives you a legacy synthesizer with professional specs good enough for the latest recording environments.
What is the digital synthesizer: D-50?
The D-50, released in 1987, was Roland's first fully digital synthesizer. Equipped with an LA (Linear Arithmetic Synthesis) format sound generator that combined PCM and subtractive synthesis, it opened the door to countless new sounds for levels of creativity surpassing anything up to that point. The D-50 is a renowned, historically significant synthesizer that Roland, the company that laid the foundation for digital synthesizers, is proud to have created.
The D-550, also released in 1987, shrank the D-50's powerful synthesizer engine into a mere two rack spaces.

Now, more than fifteen years after it came on the scene, the D-50 continues to be used by creative artists around the world. There are numerous sound libraries stocked with many original patches. In the course of time, however, keyboards and buttons age and wear out. It looked like the day would come when the D-50's sounds would no longer be heard.
In taking up the challenge of realizing new possibilities for the synthesizer, Roland has created a revolution in technology. At the same time, we want you to continue to using your treasured D-50 with peace of mind. Hence, the VC-1, which transforms your V-Synth XT into a D-50, not only sweeps away any worries about your D-50 growing old, but also offers new potential that goes beyond the original instrument.
We hope that you will discover and enjoy the unrealized potential that the D-50 still offers. And if you have never played the D-50, you definitely need to check out its vintage sounds.
When using the VC-1, the actual functions of the V-Synth XT's buttons and knobs may not correspond to the functions ascribed to these controls on the V-Synth XT's panel. Here is a description of the names and functions in each section of the V-Synth XT when it is used with the VC-1. Please read this material together with "Panel Descriptions" in the V-Synth XT Owner's Manual.
