Introduction
VariOS-8 is a trial application that transforms your VariOS into a completely different sound module.
When the VariOS-8 program is installed, you can use the VariOS as an analog modeling synthesizer.
You can use a rich array of parameters to produce realistic analog synthesizer sounds.

About this program
File structure
• VariOS-8 main program
If this program is installed in the VariOS's internal flash ROM, the VariOS can function as an analog modeling synthesizer.
• VariOS-8 controller software (Windows/Macintosh)
This is editor software that lets you control the functions of the VariOS-8 from your computer.
Features
Once you have installed the program into the internal flash ROM of the VariOS, you can use a simple button operation to start up
the VariOS as the VariOS-8. Since the previous program will still remain, the normal power-on operation will start up the VariOS
with its conventional functionality.

Page 2: Specifications/System Requirements
* Although Roland has tested numerous configurations, and has determined that on average, a computer system similar to that described above will permit normal operation of the VariOS-8 Controller, Roland cannot guarantee that a given computer can be used satisfactorily with the VariOS-8 Controller based solely on the fact that it meets the above requirements. -

Page 5: Startup And Settings
Before you start up VariOS-8 Controller, you must connect the VariOS to your computer via a USB cable and start up VariOS-8. If you first start up VariOS-8 Controller and then start up VariOS-8 or connect the USB cable, or if you have turned off the power of the VariOS or disconnected the USB cable while VariOS-8 Controller is running, you must close VariOS-8 Controller and then restart it. - Page 6 If you’ve connected a MIDI keyboard, set this channel to match the channel your MIDI keyboard is using for transmission. * The setting of the Receive Ch field is linked with the [Menu2 Receive Channel] setting of the VariOS hardware module. Refer to “Setting the MIDI Receive Channel” on p. 8.

Page 22: About Midi Channels
When playing VariOS-8 from a sequencer, choose Roland VariOS MIDI as the output port for the corresponding track in your sequencer, and set the MIDI output channel to match the MIDI Receive Channel of the VariOS. You can use either of the following two methods to set the VariOS’s MIDI Receive Channel. - Page 23 First use the "Installation" (p. 4) procedure described in this manual to copy VA.prj to the internal flash ROM of the VariOS. 1. Make sure that a PC card is not inserted in the PC card slot of the VariOS. Then use a USB cable to connect the VariOS to your computer, and start up the computer.
- Page 24 This completes the installation. Refer to "Usage," below. Usage 1. When you insert the PC card into the VariOS and power-on the VariOS, the VariOS trial application that was written to the PC card will start up. If you want to start up the internal program of the VariOS, remove the PC card and power-on the VariOS.
