The LFO Page
Adjust
This is the familiar Coarse adjust found on many other pages. Use it here to change the rate of
one of the envelope sections without reprogramming the envelope itself. This parameter doesnÕt
give you realtime control over the envelope. It is, however, a good way to adjust the natural
envelopes without switching to a User envelope and trying to approximate the Natural
envelope.
Key Tracking
This uses the MIDI note number of each key as the control input for the current layerÕs
corresponding envelope section. When the value of this parameter is greater than 1.000x, notes
above C 4 will make the envelope section run faster, while notes below C 4 will make it run
slower. When the value of this parameter is less than 1.000x, notes above C 4 will make the
envelope section run slower, and notes below C 4 will make it run faster. This gives you realtime
envelope control right from your MIDI controller. You might use it, for example, to cause an
acoustic guitar sound to decay quicker at the high end (set the key tracking to a positive value).
Velocity Tracking
Use your attack velocity as the control input for the current layerÕs attack section (this parameter
doesnÕt apply to decay or release). When the value of this parameter is greater than 1.000x,
attack velocities greater than 64 make the attack section run faster, and attack velocities below 64
make it run slower. This gives you realtime attack control over the envelope.
Source, Depth
These two parameters work together to let you assign a control like the Mod Wheel to affect the
current layerÕs envelopes in realtime. The value of the Source parameter deÞnes which control
affects the envelope section, and the value of the Depth parameter deÞnes how much the rate is
multiplied when the control is at its maximum.
Impact
Impact punches the volume during the Þrst 20 milliseconds of the attack of an envelope. Use
this feature to get maximum ÒthumpÓ from your bass and drum sounds.
This feature is incompatible with the K2000. K2000s running operating system version 3.54 or
earlier wonÕt even load programs that use Impact. K2000s running operating system version 3.8
or higher can load programs that use Impact. The Impact feature wonÕt work, but the programs
will play normally otherwise.
The LFO Page
These are low-frequency oscillators. YouÕll use the LFO page to deÞne the behavior of the two
LFOs available to each layer. LFOs are periodic (repeating) control sources. The basic elements
are the rate and shape, which deÞne how frequently the LFO repeats, and the waveform of the
modulation signal it generates.
With the K2600, you can set upper and lower limits on each LFOÕs rate, and assign a control
source to change the LFOÕs rate in realtime, if you wish.
Because of its periodic nature, the LFO is perfect for creating effects like vibrato (cyclic variation
in pitch) and tremolo (cyclic variation in amplitude). When youÕre editing LFOs, or any control
source, remember that it must be assigned to control some parameter before youÕll hear the
effects of your edits.
