[. . . ] A crossfade event is a trigger to change the value of a control -- most often but not always a fader -- between two levels, that of the current control position and that of the position in another scene, over time. If the level in the next scene is higher than the current level, the crossfade uses the 'fade up' time; if it is lower, it uses the 'fade down' time. About the crossfade Edit Event window You can edit the parameters of a crossfade event in the Edit Event window. As this window is event-specific, only the crossfade-specific elements are shown here. These are not used for crossfades Parameter drop-down list 5 1 4 2 3 Item 1 2 3 Description Crossfade Group Edit button, opens the Crossfade Groups screen (see "Crossfade groups" on page 211).

XL8 Live Performance System Owner's Manual 208 Item 4 Description Chapter 23: Crossfades (Automation) Parameter drop-down list (as shown above), for choosing the level control that you want the crossfade to operate on. For details of level control/parameter associations, see "About the crossfade parameters" on page 208. Crossfade Group drop-down list, contains all of the available user-configured crossfade groups. Also, includes the example group, which is the XL8's default group and contains all possible crossfade sources. 5 About the crossfade parameters The following diagram shows the XL8 configured for 5. 1 surround mode, which utilises each available parameter option. The presence of the divergence, centre level and LFE level sections are dependent on the currently selected surround mode. image/front back Mute Pan Front Div Fader F-R div Rear Div Mute Fader Centre Sub Figure 32: Parameter assignments Using a crossfade mute The Mute option of the Parameters list lets you initiate a mute at the end of a crossfade down operation. For example, if you set a crossfade of two seconds, the mute will turn on after this time has expired (provided it was off). If the crossfade is a `crossfade up', the mute will turn off during the crossfade up time (provided it was on). XL8 Live Performance System Owner's Manual About the crossfade Edit Event window 209 Crossfade set up section in the Edit Event window The crossfade set up section, which is at the bottom of the Edit Event window, is where you set up how the crossfade operates. Note: The graph display shows the current longest crossfade in progress. So, if a delayed crossfade starts during the current one, and it is longer than the current one, the graph will change to show the new crossfade. You can manually override the crossfade using the controls in the automation section of the output bay (see "Manually controlling a crossfade" on page 213). XL8 Live Performance System Owner's Manual Crossfade groups 211 Crossfade groups Crossfade groups let you choose which channels/buses/groups will contain the crossfade. These groups are managed at the GUI's Crossfade Groups screen. 1 2 3 Item 1 Description Crossfade source panel, contains lists of channels, buses and groups from where you select the sources for your crossfade group. To aid source selection, each list has A, I and N buttons that select all members in the list, inverts the current list selection and deselects all members in the list, respectively. Crossfade group management section, where you can create new crossfade groups or delete existing ones, add/remove members to/from the currently selected group, and select the desired group from the Control Group List. Shows the members of the currently selected crossfade group in the Control Group Member List. The ALL and NONE buttons underneath the list aid group member selection by selecting/deselecting all list members, respectively. 2 3 >> To open the Crossfade Groups screen At the GUI menu's Automation screen, click Crossfade Group Edit. XL8 Live Performance System Owner's Manual 212 Chapter 23: Crossfades (Automation) >> To set up a new crossfade group 1 2 At the Crossfade Group screen, enter your chosen name for the new crossfade group in the Control Group Name field. The new group will appear in the Control Group List. By default, your new group will contain "IN1Mic1" as a member, as shown in the Control Group Member List.
