Channel Controls
The US-224 has 4 channel strips and a master fader. The master fader controls the volume for
any and all tracks that contain master faders. Regular channel strip faders never affect a master
fader track.
Each channel strip contains a fader, a SELECT button, a SELECT
LED, a RECORD LED, a MUTE
button, and a MUTE
LED. The four channel strips affect a bank of four contiguous tracks within
Digital Performer’s Mixing Board window. The set of tracks being controlled may be changed as
described in the “Bank Selection” section below.
The channel fader directly controls the volume of a track (unless it’s a master fader track). Select
a track by pressing the SELECT button. The corresponding SELECT
LED will light. Pressing a
SELECT button will deselect any previously selected track(s). With the T
RACK window active, the
currently selected track is highlighted.
Pressing SET+SELECT will toggle the select state of a track. This may be used to select or
deselect multiple tracks, or to change the set of selected tracks.
To pan a track, select the track by pushing its SELECT button, then turn the data wheel. Holding
the SET button down while panning gives you finer control.
