Real-time Control of KDFX
Tempo-based control of KDFX
4-18
For example, letÕs look at an Algorithm that has an LFO Rate parameter in Hz. LetÕs say we
want the LFO speed to be twice as fast as the tempo. Here are the values for the FXMod:
Parameter
:
LFO Rate
Adjust
: The slowest vibrato we want is 2 x (3.75 BPM/60), or 0.125 Hz.
0.13 Hz
is the
nearest value available.
Source
:
Tempo
Depth
: The fastest vibrato we want is 2 x (240BPM/60), or 8.00 Hz, so this parameter is
8.00Ð0.13, or 7.87 Hz; the nearest value available is
7.80 Hz
.
The Tempo parameter exists in Control Source lists throughout the K2500Õs operating system,
not just in FXMod pages, so you can use it for controlling just about any function, including
pitches of sample loops, envelope lengths, Þlters, volume, and more.
Tap Tempo
A real-time tap on a footswitch or button can also be used to control the tempo of a parameter
in KDFX. Like the Tempo parameter, Tap Tempo is not KDFX-speciÞc, but can be used
throughout the K2500Õs operating system, including the Sequencer.
To use Tap Tempo, you have to assign it a physical controller inside a Setup or Control Setup (if
you are in Program mode). ÒTap TempoÓ is on the controller Destinations list, located at
number 39 (press

an octave and a major 3rd
below middle C). Tapping or pressing on a controller that is set to ÒTap TempoÓ sends tempo
information, based on the average time between taps, to the Internal Clock.
It takes four taps to determine the tempoÑif you tap fewer than four times, no information is
sent. If you tap more than four times, the average of
all
of your taps is continuously calculated
and sent to the Clock. Later taps are weighted more heavily than earlier ones, so that if you
change the rate at which you tap, the tempo information being sent will change accordingly,
but there is a ÒßywheelÓ effect, so the ClockÕs tempo changes will lag somewhat behind the
changes in your tapping rate.

In order for Tap Tempo to have any effect, the
Clock
parameter on the
Song Mode:MISC
page must be set to ÒInternalÓ.
