FBV MkII Advanced User Guide: FBV Control Application

7 - No Device Connection Indicator: If no FBV MkII device is detected when you launch the Line 6

FBV Control application, you’ll see this alert at the bottom of the application window, meaning that

you either neglected to connect the FBV unit’s USB cable, or there is a problem detecting the device:

If your FBV is disconnected, you can plug it into your computer’s USB port while the Line 6 FBV

Control application is still open, and the application will automatically detect it momentarily.

Note to Windows® Users: An inherent behavior of the Windows® 7, Vista® & XP USB Class Compliant

driver is that it does not permit more than one application at a time to utilize a common USB MIDI device’s

MIDI port. The Line 6 FBV Control application utilizes the FBV MIDI In Port to send your edited

Control settings to the FBV device. Therefore, you’ll want to avoid setting your MIDI/DAW software

to enable the FBV MIDI In port if you want to be able to have FBV Control open at the same time and

communicate with your FBV. (You typically only need to enable one of the FBV MIDI Out ports 1 through

4 within your MIDI/DAW software to receive MIDI commands from FBV.)

Footswitch Control Behaviors

As described within the Control Properties List section on page 3•3 , the FBV MkII footswitch controls

offer several different behaviors based on the type of MIDI Command and Value selected. When

selecting MIDI CC as the Command type, you’ll have the choice between three different Switch Mode

options; Single, Toggle, or Momentary. Each footswitch control is actually capable of transmitting

either one or two MIDI CC commands (depending on the Switch Mode), which is handy for some

software parameters. Different software manufacturers might utilize one switch mode or the other for

their speciﬁc parameters, so you’ll need to check their documentation to determine the best switch

mode choice. But we can provide some helpful examples of how these three switch modes work here.

For this example, let’s say you’ve selected the following options for the “A” footswitch control:

By selecting the “065” Value, this actually sets both the MIDI CC assignments for the footswitch

control to CC #65. At the far right you can see this indicated in the “Toggle 1/Up” and “Toggle 2/

Down” CC and Val ﬁelds (even though they are not editable, you can see the numerical settings that

are in use). The speciﬁc Values are automatically conﬁgured for 127 and 0, respectively. With these

settings, the resulting behaviors for each Switch Mode setting are as follows:

• Single: Always transmits only the Toggle 1/Up CC number and Value when the footswitch is

pressed (CC 65 and Value 127 in our example).

• Toggle: Alternates transmitting the ﬁrst and second CC & Value on each successive press (like

an on/off switch). So, in our example, it will send CC 65/127 on the ﬁrst press, and CC 65/0 on

the next. Some software parameters utilize this type of switch mode for things such as toggling a

function on and off. Typically, the Value of 0 - 64 toggles the parameter to its “off” state, and a

Value of 65 - 127 toggles it to its “on” state. However, you will also ﬁnd that some software titles

utilize MIDI CC commands with the Momentary Switch Mode to toggle parameters on/off (see

next bullet). You’ll want to check your documentation (or just try different Switch Modes with

your software) to see which Modes work for your application.
