Virtual V-4 Element Manual

VirtualV4 Element

Livid's "VirtualV4" Element is designed to turn an Edirol V4 video mixer into a control surface for Livid Union. Most of the V4's buttons and knobs output some sort of MIDI messages, so, in principle, the V4 could be used to control Union, just like any other MIDI controller, such as an M-Audio Oxygen 8. However, the V4's MIDI output could be politely described as "non-intutitive." We found that with some additional programming, the V4 is turned into an extremely powerful controller for Union, using an existing interface that is very familiar to V4 users. Once you start using the V4 with Union, you may find your V4 will only need a power source and a MIDI cable to your computer!

Getting Started

Opening the VirtualV4 Once Union is open, select "Elements" from the "Modules" menu, or just press cmd-E. In the Element window, select "VirtualV4" from the "Controls" menu and click the "open" button. This will load the VirtualV4 window in Union. When first using the VirtualV4, it is best to open the Union application, start with Unions Sample Project, then open the VirtualV4 Element. This will ensure that the vV4 is populated with its default effect settings for the Memory knob. Configuring your Edirol V4 for MIDI output By default, the Edirol V4 does not output MIDI information. Configuring each control can be a timeconsuming task of navigating the V4's primitive menu system. In the VirtualV4, we have programmed a process to make MIDI setup as easy as possible, so the only menu item you need to set in the V4 is the "Device ID." You may have already created a MIDI setup for your V4, in which case you will want to configure the VirtualV4 to match your settings. To avoid future confusuion.please note that the Edirol V4s BPM/CONTROL knob and TAP button do not send out MIDI, and therefore cant be used to control Union or the vV4. The vV4s BPM and TAP functions do communicate with Unions TEMPO module. The Easy Way Observe - This "Easy Way" will overwrite any existing MIDI Settings of your V4, via a MIDI sysex dump. If you wish to preserve the MIDI settings of your V4, you will not want to use the "Easy Way."
Long Version Connect MIDI Hardware - First, you'll need to connect the MIDI input and output from your V4 into a MIDI input/output device. This establishes MIDI communication between your Edirol V4 and your computer. Set Device ID - Connect a preview monitor (such as a TV) to the V4's "PREVIEW OUT" jack. On your Edirol V4, press the "MENU" button to display the V4 menu on the preview screen. Select "MIDI Setup" and press "ENTER" to enter the MIDI setting screen. Select "Device ID", and set it to "0x00" (which is hexadecimal for "0") You can use any ID you wish - just remember what it is! Send Setup from Computer to V4 - Click the blue "MIDI" button in the VirtualV4 interface to open the MIDI Configuration window. In the "DEVICE" panel of this window, select the MIDI ouptut port on which you will be sending data to the VirtualV4. Set the Device ID of the VirtualV4 you wish to configure (most likely it is "0"). If you have particular controller numbers you would like to configure the Edirol V4 to use, enter those numbers in the "SETTINGS" area of the window. Press the "send" button to send the current setup to the V4. Congratulations - your V4 is setup to transmit MIDI to Livid Union! Move the knobs and click the buttons on your Edirol V4, and the corresponding controls in the VirtualV4 will animate and send data to Union. If you changed the settings at all, you will probably want to press the bottom "save" button to write the setup as the default MIDI setup. This file is saved in the "Defaults" folder as "VirtualV4MIDI.txt" and is read automatically when the VirtualV4 Element is opened in Union. The Less Easy Way If you have an existing MIDI setup programmed in your Edirol V4, you will likely want to configure the VirtualV4 to match that setup. Navigate the Edirol V4's menus to confirm the MIDI settings for all the controllers. If there are any that are off, set them to the desired controller number. In the Virtual V4's window, select the MIDI port and channel ("Tx Channel") on which the v4 is sending data. Click the blue "MIDI" button in the VirtualV4 interface to open the MIDI Configuration window. In the "SETTINGS" area of this window, enter the controller numbers that correspond to the settings you noted in the Edirol. The VirtualV4 is now configured to respond to your Edirol's MIDI output. Press the bottom "save" button to write the current setup as the default MIDI setup. This file is saved in the "Defaults" folder as "VirtualV4MIDI.txt" and is read automatically when the VirtualV4 Element is opened in Union.

Using the VirtualV4

The "VirtualV4" is designed to replicate the experience of mixing analog video sources on an Edirol V4. The basic architectures of Union and the V4 are quite similar: two channels of video (A/B), four layers of effects per channel, and instantaneous control of your media. Once you have configured your Edirol V4 for MIDI, you can use its buttons, knobs, and Tbar to mix and effect video and Union, with onscreen feedback of the controls actions. You can, of course, mix analog video inputs with the Edirol V4 while controlling Unions digital media at the same time! Following are explanations of each area of the V4's interface and how they relate to controlling Union.
Transition & Transform Buttons The three buttons "Mix", "Wipe", and "EFX" change the action of the Tbar as follows: "Mix" will crossfade between A and B. "Wipe" will engage the "Metrics Position X" effect in Union, moving Channel A's image from left (offscreen) to center. "EFX" will engage the "Metrics Zoom" effect, changing the size of Channel A's image from 0x to 3x normal size. The "BPM Sync" button will automate the action of the Tbar according to the BPM in the VirtualV4's display. Note that the Edirol V4's BPM display is irrelevant for this program, since there is no way to transmit BPM information from the Edirol hardware to Union. The transform buttons behave as you would expect: if the Tbar is leaning to Channel B, the Transform A button will result in only Channel A's image output, until the Transform A button is released. Effects and Memory Each channel has four effects buttons, corresponding to Union's four Effects layers. Just like the sliders and knobs in Union's Main interface, you can assign any Effect Parameter to these four buttons. To activate an effect, press one of the buttons on your Edirol V4, then use the "Control" knob to change the value of that parameter. The Control knob will change the value of the most recently activated effect. The Virtual V4 emulates the effect button behavior on the Edirol V4. As a result, you are not able to simultaneously use all four layers of effects that Union offers. (If this bothers you, let us know! We decided it was more important to emulate exactly the V4 to reduce performance time-confusion.) Of course, the memory knob can be used to store and recall different arrangements of effects on the A and B channels. Just assign some effects and parameters on A and B, then turn your Edirol V4's "Memory" knob to a new location number. These setups are saved with your Union Project, and restored when a project is open. When you first open the Virtual V4, it will automatically load the Virtual V4 settings in that project. Input Select The input buttons can be used to select different video clips to play on Channels A and B, as well as turn on video digitizer input. Buttons 1-3 on will select video clips 1 thru 3 on Channel A, and button 4 will turn the Video Input on, much in the same way the "Clips/Video In" buttons work in Union's Main interface. Channel B's input select buttons will work similarly, but input select 1-3 will trigger movies 4-6. There are probably a million different maps that could be used for the Input Select buttons, each satisfying a different performer's desire. Let us know your ideas, or download the source code (see below) and make your own in Max/MSP! BPM Control & Tap BPM control is tied to the "Tempo" module in Union, and can only be controlled onscreen with your mouse or "tab" key. It is unfortunate that the Edirol V4 does not send MIDI clock or tap information, but that's the way it is! As a result, the BPM display of the Edirol won't match the display in the Virtual V4. If you want everything to look matched and you are using an external MIDI clock to sync Union, you can send that clock to the Edirol V4 by turning the "Sync V4 to MIDI Clock" switch on in the Virtual V4's MIDI

configuration window. If you are using the V4 to mix analog source AND Union at the same time, then this will be a functional bonus! Output Fade By default, the output fade knob will affect Union in same way the knob works on analog source for the Edirol V4. Turned all the way to the left, output will be black. In the middle, images will display at normal brightness. Turned all the way to the right, the output will be fully white. But because the Virutal V4 is so damn cool, you can of course remap this knob to any effect parameter you want, and it will act on whatever the current layer is, as assigned in the main Union interface. Previews On computer systems with smaller monitors, the Virtual V4's window will likely cover the preview windows of Union's main interface. If this is the case for your setup, you will probably want to turn the preview windows on, using the "V-4 Previews" button in the top right of the window.
The VirtualV4 is merely a patch designed in Max/MSP, saved as a collective. You can download the source code for the VirtualV4 from http://www.lividinstruments.com/elements/virtualv4/VirtualV4-src.zip Special thanks to Brian Dressel of OVT Visuals for testing and inspiration!

About Ground Terminal

In some cases, depending on the environment in which the unit is installed, the surface of the panel may sometimes feel rough and grainy. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect ground terminal (see figure) with an external ground. When the unit is grounded, a slight noise may result, depending on the particulars of your installation. If you are unsure of the connection method, contact nearest Edirol Service Center, or authorized Edirol/Roland distributor, as listed on the Information page.

Ground Terminal

Unsuitable places for connection
Water pipes (may result in shock or electrocution) Gas pipes (may result in fire or explosion) Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
Connecting peripheral devices
This section explains how to connect your peripheral devices to the V-4. You can connect up to four video playback devices (sources). Heres how to connect sources such as a video camcorder, VCR, DVD player, or DV7PR, and play them back to create an impressive video performance. To prevent malfunction and/or damage to other devices, always turn down the volume, and turn off the power on all devices before making any connections.
Typical connection example

DV-7PR VCR DVD Camcorder

Projector

Preview Monitor

The V4 does not have audio inputs so will not mix audio. Audio outputs can be connected directly to speakers or via an audio mixer if mixing of audio from multiple devices is necessary. No video cables come with this product. Please use appropriate video cables for connection with source devices or TV monitor/Projector. It is recommended to use composite cable rather than S-video cable where you need to connect devices long distances (unless using S-video amplifiers). If devices are installed closer to the V-4, it is recommended to use S-video cables so that you can obtain better image quality. If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the Svideo signal will take priority.

Video signal flow

The video signals received from the four input jacks are assigned to channels A or B of the video mixer. (These assignments are made manually.) The signal of A and B channels are processed by the video mixer section, and sent via the output fader to the output jack.

Various setting menus like effect parameters are displayed on preview monitor. If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the Svideo signal will take priority. When switching on Preview Selector is done, image on preview monitor may flicker briefly. This does not affect image from output jacks.

Turning the power on/off

Turning the power on
1. Check the power cable Make sure that the cable from the AC adaptor is firmly plugged into the V-4. 2. Press the POWER button. Press the POWER button located on the rear panel of the V-4. It will take approximately five seconds for the V-4 to initialize itself and begin operating.
To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown in the illustration.

Turning the power off

1. Press the POWER button. Press the POWER button located on the rear panel of the V-4. All of the front panel LEDs will go dark.
Checking the inputs and outputs
Checking the final output
Heres how to check that the signal from each source device is correctly being input to the V-4, and is correctly being output to the TV or projector as final output. 1. Play back the source device. Operate the source device (e.g., camcorder, VCR, DVD player, DV-7PR) connected to the V-4 so that it will output video. 2. Check the output monitor. Power-on the TV monitor or projector that is connected to the output jack of the V-4, and verify that the image being output from the V-4 is displayed correctly. 3. Switching the input channel Now, try switching the V-4s input channel. Move the T-bar all the way toward the channel A or channel B position. If you moved the T-bar toward channel A, press the left input selector (INPUT SELECT). If you moved the T-bar toward channel B, press the right input selector. Successively press buttons 1 through 4 to switch inputs. Confirm that the image shown on your TV monitor or projector changes accordingly.
In the case you do not see output on TV/Projector

If you want to change the direction in which the image is inverted, you will need to edit the parameter settings. For details on making this change, refer to p. 75 or later.
Switching in synchronization with music
The V-4 can switch images in synchronization with the beat of the music. You can use the BPM or TAP functions to switch images as you see in VJ performances.
Using BPM sync to switch images
You can use BPM (Beats Per Minute) to specify the timing at which images will be switched. The V-4 will switch automatically, without you having to operate the video fader or the transformer buttons. 1. Input images to channels A and B. Use the channel A and B input selectors to input images into each channel. Input different images into channels A and B. 2. Set the BPM. Turn the BPM control dial (BPM CONTROL) to set the BPM. Smaller values will cause the images to be switched more slowly, and greater values will cause faster switching.
Press the BPM sync button (BPM SYNC). Press the BPM sync button. Notice that the images switch in time with the BPM you specified. You may also turn the BPM dial at this time to change the timing.
Using the tap (TAP) function to switch images
As an alternative to specifying the BPM numerically, you can use the tap button (TAP) to specify the timing at which the images will switch. 1. Input images to channels A and B. Use the channel A and B input selectors to input images into each channel. Input different images into channels A and B. 2. Press the BPM sync button (BPM SYNC). Press the BPM sync button. The images will begin switching at the BPM timing shown in the BPM indicator.
Press the tap button (TAP) in time with the music. Play back the desired background music, and press the tap button in time with the beat. The BPM readout will be constantly updated to reflect the timing you use while tapping the button, and the images will switch according to this BPM.
Applying an effect on the music
The V-4 cannot only switch images but can also apply effects in time with music. You can use the BPM or TAP functions to apply effects that are synchronized with the music, as in a VJ performance.
Using BPM sync to apply an effect
You can use BPM (Beats Per Minute) to specify the timing at which an effect will be turned on/off. The V-4 will apply the effect automatically, without the need for you to operate the buttons manually. 1. Input the same image into channels A and B. Use the channel A and B input selectors to input the same image into both channels. If you choose input select button 1 for channel A, choose button 1 for channel B as well. 2. Select the type of effect. Decide whether you will use a channel A effect or a channel B effect. 3. Set the BPM. Turn the BPM control dial (BPM CONTROL) to set the BPM. Smaller values will cause the effect to be switched on/off more slowly, and greater values will cause it to switch more rapidly. 4. Press the BPM sync button (BPM SYNC). Press the BPM sync button. Notice that the effect is applied to the image in synchronization with the BPM you specified. You may also turn the BPM dial at this time to adjust the timing.

Changing the assignment of the mix button (MIX)
With the factory settings, mix (MIX: dissolve) is assigned to this button for all eight positions of the memory dial. Heres how to assign a different type of transition effect to the mix button for one of the dial positions. 1. Set the memory dial to the number whose settings you want to change. Set the memory dial to the number (2 through 8) whose settings you want to change.
Press the mix button(MIX) The button lights up when pressed.
Press the menu button (MENU). Press the menu button (MENU) located in the upper left of the panel. The settings edit menu will appear on the TV screen connected to the preview output.
Select MIX. Use the cursor buttons to select Mix (Trans1). It will blink when you select it. The memory dial number you select is displayed following Mix (Trans1). If you have selected memory number 2, this will indicate [Mem2].
Press the enter button (ENTER). Press the enter button (located at the right of the cursor buttons) to make your selection. The preview screen display will change.
Select the transition effect. Use the cursor buttons to select the type of transition effect. With an effect selected (blinking) and the video fader set in the center position, the output screen will show the type of transition effect that is selected. Operate the video fader to see the result.
Return to the previous screen. When you have selected an effect, press the menu button to return to the previous screen. Press the button twice to exit the menu screen and return to the previous screen.
Changing the assignment of the wipe button (WIPE)
With the factory settings, eight basic wipes are assigned to this button for the eight settings of the memory dial. Heres how to assign a different type of transition effect to the wipe button. 1. Set the memory dial to the number whose assignment you want to change. Operate the video fader while you turn the memory dial to different positions. Notice how the dial selects different wipe patterns. Set the memory dial to the number (2 through 8) whose settings you want to change.
Press the wipe button (WIPE) The button lights up when pressed.
Select WIPE. Use the cursor buttons to select WIPE. It will blink when you select it. The memory dial number you select is displayed following WIPE (Trans1). If you have selected memory number 2, this will indicate [Mem2].

If you want to start up in Normal mode and then switch to Presentation mode by making a menu setting, choose the Utility menu item V-4 Mode and then select Presentation.
Switch the background image. Successively press the channel A input select buttons 1 through 4 to switch the image.
Apply the Picture In Picture function. Set the memory dial to number 2. Picture In Picture will be applied.
Apply other effects to composite two images. Turn the memory dial to other positions to try out other types of effects. Numbers 2 - 5 change the location of the secondary screen of the Picture In Picture function. Numbers 6-8 apply other effects (luminance key/chroma key).
Switch the secondary image. Press the channel B input selector buttons to switch the secondary image.
Switching between NTSC and PAL
The V-4 can be switched to support either NTSC or PAL format signals. To start up in PAL mode, hold down preview select button 1 and OUTPUT, and press the power button.
The next time you start up, you can simply press the power button to start up in PAL mode. If you want to return to NTSC mode, once again hold down preview select button 1 and OUTPUT, and press the power button.
When the V-4 starts up, an indication of whether it is starting up in NTSC mode or PAL mode will appear for several seconds in the preview screen.
Changing the video fader orientation
The V-4s T-bar style video fader may be installed in either the horizontal or vertical orientation depending on your preference. When shipped, the video fader is installed for vertical operation. If you prefer to operate the fader horizontally, you can turn the video fader 90 degrees. 1. Remove the screws. Four screws fasten the video fader. Remove these four screws from the round video fader mounting plate, being careful not to lose them.
Reposition the video fader. Turn the video fader 90 degrees. Align the triangle printed on the round mounting plate of the video fader with the triangle printed on the panel of the V-4.
Fasten the screws. Fasten the video fader to the panel, using the screws that you removed earlier. Firmly tighten all four screws.
The cable that connects the video fader to the V-4 may become disconnected if you pull strongly when unfastening the video fader panel. Please use caution when pulling the T-bar away from the panel.

If you attempt to rotate the vide fader panel further than 90 degrees, the internal cable may be damaged. Note the location of the triangle symbols, and do not rotate the video fader panel further than 90 degrees.
To remove the screws, use a screwdriver that matches the screw heads, and work carefully. If the screw heads become damaged, you will be unable to fasten the video fader in place.

Troubleshooting

If you suspect a malfunction, please check your system once again, taking note of the points listed below. If it still does not function correctly, contact an Edirol Service Center or the dealer where you purchased the unit.
Operating the video fader does not switch the image
If the same image is being input to channels A and B, operating the T-bar will not produce any change in the output image. You must input different images into channels A and B.
Operating the transformer buttons (TRANSFORMER) does not switch the image
With the factory settings, when the memory dial is set to 1, these buttons will cut between images. Check the position of the memory dial.
No image is output even though you play back the source device
Make sure that the output fade dial is set to the center position (green LED lit). With the factory settings, turning the dial toward the left will fade to black, and turning it toward the right will fade to white. If the dial is set all the way to left or right, no image will be output. Also make sure that the input select setting is correct.
Turning the control dial does not change the effect
Not all effects have parameters that can be modified by the control dial. If you have selected an effect whose parameter can be modified by the control dial, the channel A/B effect button will blink. If the button is only lit (not blinking), the control dial will not affect the parameter.
Image does not switch (effect not applied) in time with the BPM
Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be pressed if you want to switch the image or apply an effect in time with the BPM.
Image does not switch (effect does not apply) in time with TAP
Did you press the BPM sync button (BPM SYNC)? The BPM sync button (BPM SYNC) must be pressed if you want to use the TAP button to switch the image or apply an effect.
Operating the video fader does not switch the image in the expected direction
It is possible that if you detached the video fader to reposition it by 90 degrees, the internal connector may have been pulled out and re-inserted in the opposite orientation. Detach the video fader with its mounting plate, and try reinserting the connector in the opposite orientation.

Examples of using the V-4
Using the V-4 at an event
Heres an example of using the V-4 to switch between multiple live images and sources such as a video tape, as might be used at events such as exhibitions or performances.

Live source Preview

Large display (plasma) Video images
Advantages of using the V-4
Two images (two live images, or live video + recorded video) can be mixed Use picture-in-picture to display two screens simultaneously * * For details on switching images, refer to p. 23. For details on using picture-in-picture, refer to p. 26.
Using the V-4 at a concert or VJ performance
You can project the output image on a large screen such as the stage backdrop, and create a video performance that follows the music. Images from the DV-7PR can be mixed with multiple live images.

Projector (1)

Projector (2)
Use BPM/TAP to switch images in time with the music Use numerous effects such as mirror, strobe, or colorize * * * For details on using BPM/TAP, refer to p. 37. For details on using strobe, refer to p. 34. For details on using colorize, refer to p. 32.
Using the V-4 at a presentation
You can use the V-4 to switch between live images and VTR/DVD output, or add images/text from a personal computer.
* If you are using a personal computer that does not have a video output, you will need to use a scan converter to convert the computers VGA output into a video signal.
