Control Sources
Main Control Source List
4-9
You can use this control source in several ways. One example is to limit the volume
of each note so that you have a more nearly constant volume regardless of how
many notes youÕre playing (this is independent of the effect of attack velocity on
volume). To set this up, you would go to the F4 AMP page in the Program Editor,
and set the Src1 parameter to a value of
ChanCnt
. Then set the Depth parameter to
a negative value. This will decrease the overall amplitude of each note as you play
more simultaneous notes. This example works best with short-release sounds. ItÕs
great for an organ program, for example.
Channel count is also useful for controlling the modulation applied to a sound. For
example, you may have a sound that you use both as a lead and for rhythm.
Suppose you want a deep vibrato when youÕre soloing, but less vibrato when youÕre
playing chords. Set up the vibrato by using
LFO1
as the value for the Src2
parameter on the PITCH page in the Program Editor. Set the MinDpt parameter to
72 cts
, and the MaxDpt parameter to
12 cts
. Then set the value of the DptCtl
parameter to
ChanCnt
, and YouÕll get maximum vibrato depth when only one note
is active. (Channel count outputs a control signal of 0 when no notes are playing, so
with only one note playing, its value is near 0, which causes the DptCtl parameter to
generate a value near its minimum: 72 cents in this case.)
If you want to increase the depth of the vibrato as you increase the number of active
notes, set the value of the MaxDpt parameter higher than that of the MinDpt
parameter.
Note
: There are no control sources that correspond to the numeric entries 47Ñ54.
55 Sync State (SyncSt)
This unipolar control source responds to MIDI clock messages received from an
external MIDI device. Sync State switches on (+1) at each clock start, and switches
off (0) with each clock stop.
56 A Clock
This is a unipolar square wave that responds to MIDI clock messages. It switches to
+1 and back to 0 with every clock beat. This control source looks Þrst for externally
received MIDI clock messages, and if none is received, it responds to the K2600Õs
internal clock, which is always running. The internal clock speed is set with the
Tempo parameter in Song mode.
57 Negative A Clock (~A Clock)
This is the opposite of A clock, that is, it switches from 0 to +1 with every clock beat
(the square wave is 180 degrees out of phase with that of A Clock).
58 B Clock
This is similar to A Clock, but itÕs bipolarÑit switches from +1 to -1 with every clock
beat.
59 Negative B Clock (~B Clock)
The opposite of B Clock, this bipolar control source switches from -1 to +1 with
every clock beat (the square wave is 180 degrees out of phase with that of B Clock).
