PROFORMANCE

BASIC OPERATION
■
Power/MIDI Activity LED -
Glows green, indicating that
power is connected and flashes when MIDI data is being
received.
■
Volume Control -
This is the master volume control. The
PROFORMANCE has a relatively high output level in order
to drive headphones. If you hear the sound start to "break up"
or clip, the output level should be reduced using this control.
■
Fine Tune Control -
This control is used to tune the
PROFORMANCE to other instruments. With the control set
in the center detent position, the PROFORMANCE will be
precisely tuned to concert pitch (A=440 Hz). Tuning the
control clockwise raises the pitch and turning it counterclock-
wise lowers the pitch. The range of this control is ± 1/2
semitone, with a resolution of 1 cent (1/100 semitone).
■
Transpose Selector -
Transposes the PROFORMANCE
up or down one octave in semitone increments. It also has
settings to transpose ± 1 or 2 octaves. Transpose selections are
referenced to C on the musical scale. With the control set
straight up at C, there is no transposition. The two positions
on either side give 1 and 2 octave transpositions. As the knob
is rotated clockwise, transpose is shifted up in semitone steps
from C# up to B. When the knob is rotated counterclockwise,
transpose is shifted down in semitone steps from B down to
C#.
