Lexicon PSP 42 Operation Manual
14
The DLY<>CLK switch
switches between the two main Lexicon PSP 42
operation modes. In DLY mode the delay time is set in ms using DN/UP buttons or
any of two the invisible sliders available. In CLK mode time is tempo-related. If
your host is capable of providing the plug-in with tempo information, Lexicon PSP
42 will automatically lock to it. If not - it is still possible to set the tempo manually
by dragging the invisible sliders while in CLK mode. The DN and UP buttons
navigate through the allowed numerator and denominator values, respectively.
When either shift or ctrl is pressed, the numerator/denominator value is decreased.
The resulting fraction is the delay time as part of one bar (e.g. ¼ means the delay
time of one beat or quarter note). If the resulting actual delay time exceeds the
maximum allowed value (due to the limited delay buffer size) the numerator and
denominator values start to blink. If plug-in is locked to the tempo information
received from host application, tempo changes affect the actual delay time in real
time.
When switched from CLK to DLY mode, the delay time in ms is always set to be
equal to the time resulting from the numerator/denominator settings and tempo. It
enables the delay time to be set in rhythmic units in CLK mode and then to be made
independent to host tempo changes, by switching to DLY mode. The fine
adjustments can be applied as well if the exact timing is not intended.
When switched from DLY to CLK there are three possible ways the Lexicon PSP
42 can act, depending on the key pressed while switching:
-
no key
- the recent numerator and denominator values are restored,
-
alt
- the latest denominator value is restored and numerator is recalculated to
match the tempo, set in ms as close as possible,
-
shift –
both the numerator and denominator are recalculated to match the tempo
set in ms, as close as possible.
The DN/UP buttons
change the
delay time up and down when in DLY mode. Shift
and ctrl keys alter the step size to 10 and 100, respectively. When CLK mode is on,
the buttons navigate through the allowed numerator and denominator values. Please
note that changing the denominator value, may imply the automatic change of the
numerator value too, if the resulting delay time exceeds the internal buffer size. Be
aware that the actual delay time is the result of the delay buffer size, which is set by
DN and UP buttons and invisible sliders, and the delay buffer sampling rate which
is affected by the modulation section, MANUAL knob and DLYx2 button.
The DELAY TIME invisible sliders
let the delay time and tempo to be controlled
with the mouse in a convenient way. Clicking the left mouse button on any of the
sliders and dragging left and right (or up and down for faster changes) controls the
delay time or tempo depending on the mode Lexicon PSP 42 is operating in.
Pressing shift while dragging allows for fine adjustments. Manual tempo
adjustment is not possible if host application provides the plug-in with tempo
information.
