Control Sources
Descriptions of Control sources
25-9
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 first for exter-
nally received MIDI clock messages, and if none is received, it responds to the
K2vxÕs 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 ev-
ery clock beat (the square wave is 180 degrees out of phase with that of B Clock).
60, 61 Global Phase 1 and 2 (G Phase 1, G Phase 2)
These bipolar global control sources are both rising sawtooth waves that rise from
-1 to +1 with each MIDI clock beat. Like A Clock and B clock, they look for an ex-
ternal clock signal, and if none is received, they respond to the K2vxÕs internal
clock.
62, 63 Global Random Variant 1 and 2 (GRandV 1, GRandV 2)
These are also bipolar and global, and generate random control signal values be-
tween -1 and +1 when assigned to a control source parameter. There is a subtle dif-
ference in the randomness of the signals they generate, therefore choosing between
them is a matter of preference.
96 Note State (Note St)
At any moment, any given note is either on or off; this is its Note State. Note State
can be used as a unipolar control source that responds to each note thatÕs played.
It switches to +1 when the note starts, and stays on as long as the note is held on
(by the sustain pedal, for example), or by holding down the trigger for that note. It
switches to 0 when the note is no longer sustained by any means. For example, if
you play a note, then hold it with the sustain pedal, its Note State is still on (+1)
even if youÕve released the key that triggered the note. As soon as you release the
sustain pedal, the noteÕs Note State switches to off (0), even if it has a long release
and you can still hear the release section of the note.
97 Key State (Key St)
This is a unipolar control source that responds to the motion of your MIDI control-
lerÕs keys. It switches to +1 when a key is pressed, and switches to 0 when the key
is released. Its effect differs from Note State in that when the key that switched it
