Tracktion 4 Reference Manual

Note: You can quickly arm or unarm all tracks by holding down the MCU’s shift button, and simulta-
neously pressing the record button.
Signal: The MCU’s green signal LED will illuminate in time with a channel’s audio level, in order to
show that audio is present on that channel. The light will illuminate solidly when the channel’s signal is
at 15 dBFS.
Solo: Toggles the track’s solo state.
Mute: Toggles the track’s mute state.
Select: When the MCU is in plug-in mode, the select button selects the track ready for plug-in editing.
A scribble strip at the top of the unit displays information related to the cur-
rent track, or V-pot. The information displayed on the scribble strip depends
on the mode that the MCU is in. The four modes are: pan, aux, plug-in, and
marker (Fig. 7.4.9). These modes are available by selecting the correspond-
ing button in the assignment group. They are described below:
Pan mode: When the MCU is in pan mode, the V-pots control panning for
the eight current tracks. The pan position is shown by an LED in the V-pot’s
collar. Pressing the V-pot causes the pan to reset to centre. The scribble
strip shows the track name for each track on the top row of the LCD, to make
track identication easy. A level meter is also shown on the bottom row of the
LCD for each track.
Aux Mode: When the MCU is in aux mode, the V-pots are assigned to the
auxiliary send lter’s send amount. The page left and right buttons select
which auxiliary bus is currently active. The scribble strip shows the track
name, along with the currently selected aux send.
Plug-in Mode: When the MCU is in plug-in mode, the V-pots are assigned to
the parameters of the currently selected lter. The cursor and zoom buttons
can be used to move between the lters in your edit. The scribble strip shows
the current parameter, and the current level for each of the V-pots. The page
left and right buttons can be used to scroll through the lter’s parameters, if
there are more than eight.
Markers Mode: When the MCU is in markers mode, the V-pots act as push
buttons that can be used to quickly jump between markers in your edit. The
marker names are shown on the scribble strip for easy identication. The
page left and page right buttons allow you to page backwards and forwards
through the markers eight at a time.
The fader banks buttons can be used to scroll the MCU through Tracktion’s
tracks. The bank left/right buttons move eight tracks at a time, whereas the channel left/right buttons
scroll just one track at a time.
Flip: The ip button transposes the faders and V-pots, such that the V-pots act as volume controls, and
the faders are assigned to whatever task the V-pots were previously serving. You can use the ip option
in all of the MCU’s modes, so the faders can be used to control lter parameters or aux send levels, for
example.
The large scrub wheel at the lower right-hand corner of the MCU is used to scroll the play-head cur-
sor through the edit. It is equivalent to using the LEFT and RIGHT CURSOR keys on your keyboard.
To the left of the wheel there are four arrow buttons, and a zoom button. The up and down arrow but-
tons scroll vertically through the on-screen track list. The left and right buttons scroll the edit horizontally.
These two buttons are equivalent to dragging the scroll bars located below the tracks, and to the right of
the lter section.
