Frontier AlphaTrack Description

AlphaTrack Elements
The AlphaTrack is shown in Fig. 1 above and Fig. 2 below. The unit has a 100mm touch-
sensitive, motorized fader, 22 momentary pushbuttons, a touch-sensitive horizontal strip, three
encoders (which also act as pushbuttons), 21 LED’s, and one 16-character by 2-line backlit LCD
display. (Note that 4 buttons on the left have LED’s under them used in a backlit fashion. It is
powered from its USB cable.
The following sections describe the MIDI implementation for each of the AlphaTrack’s
elements. Note that any LED that is associated with a button shares the MIDI note number with
that button; the button activity is reported via the AlphaTrack MIDI IN device, and the LED is
controlled via the AlphaTrack MIDI OUT device. The AlphaTrack makes no internal logical
connection between a button and an LED – the application must control LED’s directly.

There are a few “local” adjustments on the AlphaTrack. The first adjusts the LCD’s contrast. To
access it, hold the SHIFT and STOP buttons down. The LCD will display local operation labels.
