Tempo, Timing and Cycling
10.1
TEMPO
The "Tempo" parameter controls the rate
of
the Cloning output if being driven by the
CJclone's
internal hardware clock. It
is
displayed
as
one-half the actual beats
per
minute due to the wide range
of
available tempos and the limits
of
the 2-digit display.
The Tempo range is displayed
in
"Beats Per Minute" from
10
bpm to 398 bpm (each
beat represents a quarter-note). This translates to a display range
of
5 bpm to 199 bpm
when cut
in
half. (Note that the display will revert to the "deciheximal" convention at
an actual Tempo
of
200 bpm).
If
either External Sync
or
MIDI Sync has been selected
in the corresponding Master Parameters, the Tempo parameter display shows
f1EC"
as
a reminder, and editing
of
the Tempo
is
not allowed.
When
in
Play Mode, the Play LED will flash at the actual Tempo as an indicator that
the Sync source is providing the appropriate timing reference. This applies to the
internal hardware clock as well.
Tempo
Tap
The C)'clone provides the ability to "tap" a Pedal
in
order to define
or
alter the
Tempo. The procedure for defining a Pedal
to
do this
is
described
in
the "Pedals"
section. (Note: the
Cyclone
ships from the factory with Pedal 4 already set for Tempo
Tap). This section describes how
to
actually use that Pedal for Tempo
Tap
in real-
time. Assuming that such a Pedal has been assigned, all that is required is to
understand how the
C)'clone interprets the taps received from the
Tempo
Tap
Pedal.
Each tap is considered to represent a quarter note. The C.yclone uses an average
of
the
two intervals defined
by
the last three taps to calculate what the intended Tempo should
be. The full range
of
the Tempo parameter
is
available from the the
Tempo
Tap
Pedal,
so a little arithmetic shows that the slowest tap that can be interpreted
is
6 seconds.
Once beyond the 6-second limit, the
Tempo
Tap "times out" and resets, throwing out
the previous tap times and starts waiting to get three new beats to update the Tempo.
If
a tap is missed, it
is
possible to force an early reset by pressing and holding the Enter
button and then tapping once. This can be useful since 6 seconds
is
often a long time to
wait
in
a piece
of
music.
As the resolution
of
the tapped Tempo is much more than can be displayed, the Tempo
is shown with the Value/Edit dot lit
if
the Tempo has been defined by tapping. The full
resolution is also stored and recalled with the Program.
