If "Audio During Fast Forward/Rewind" is not selected under Setups/Preferences.../Operation, then you
can tap the REW or FFWD keys to move backward or forward in steps. (The step size depends on your
selected time display mode.) Or you can hold down the REW or FFWD keys to move the time line
continuously.
"Pass Through Null" Controls
In using the US-428 with Pro Tools, the physical faders and rotary control positions at times will not match
their on-screen counterparts. When you move a control, like a level fader, pan control, or effect parameter
knob, it will not affect the on-screen control until it has moved past the on-screen position, called the null
point. The on-screen control will then stay locked to the physical control after this. Once you have stopped
moving the control, it will still stay locked until the Touch Timeout time has passed. Then, once again, you
have to pass through the null point to regain control. (You can adjust the Touch Timeout setting in
Setups/Preferences.../Automation.)
Channel Strips
Each channel strip has controls for level, mute, solo, select, and record enable. The channel strip fader
controls the corresponding on-screen level fader, but remember that you must move it through the on-
screen position before it takes effect. As you start to move a fader that is not locked to its on-screen
counterpart, either the HI-MID or LO-MID LED will light up to show you which direction you need to move
the fader to reach the null point.
You can press the MUTE keys to mute/unmute a channel. The MUTE light displays the current MUTE
state for that channel. If you press the SOLO key, the SOLO LED will light up and you are in SOLO mode.
Now the MUTE keys become SOLO keys for the 8 channels, and the MUTE lights become SOLO lights.
Press the SOLO key again, and you are back in MUTE mode.
Pressing a SELECT key selects a track for panning, send level, or plug-in parameter control, and
deselects other tracks. Once selected, its on-screen name will be highlighted in green. Hold the SET key
and press SELECT to toggle the selection of a track for editing, deleting, etc. Its on-screen track name will
get a white background.
You can move to different banks of 8 channel strips by using the BANK keys (<BANK and BANK>).
Pressing these will move the selection by 8 to the right or left (or as far as possible) and the MUTE and
REC lights will be updated for the currently active channel strips. The currently selected track for panning,
etc. will also move (and the same green LED will stay lit).
Changing Parameters
When a track is selected, you can use the four rotary knobs in different ways to control the track's pan
setting, send levels, and plug-in parameters. There are different sets of parameters for a track that these
four knobs can control. The "top" set includes pan, and five send levels. With a track selected, you get to
its top parameter set by holding LOCATE> and pressing the HIGH key. The HIGH LED lights to show that
the top set is selected.
Now you can move the PAN knob (through the null point!) to change the pan setting for the selected
track. You can also change the send level for all five sends, A through E. (See the summary at the end for
details.) Hold the SET button while moving a knob for finer control.
On screen you can select any plug-in and display its settings. The track for the plug-in, if it is different
than the selected track, will have its name highlighted in red. Load the "4-band EQ II" plug-in in an insert.
Now press the LOW button several times. As you do, a set of plug-in parameters is highlighted (up to 6 at
a time for a plug-in). The set goes to the bottom then cycles back to the top. Now try turning an EQ knob
back and forth. Once it moves through the parameter's null point, you can control it with the US-knob. All
six plug-in parameters selected can be controlled (only 4 are used per set for this EQ). See the summary
at the end for details, and for more on using plug-ins with Pro Tools, see "DigiRack Plug-Ins Guide.pdf"
that came with Pro Tools.
