AMS (Alternate Modulation Source) List
Physical and MIDI controllers
Off
This means that no modulation source is selected.
Note Number
This is the note’s MIDI note number, from 0 (C-2) to
127 (G9).
Velocity
This is the note’s MIDI note-on velocity.
Exponential Velocity
This is MIDI note-on velocity through an exponential
curve. The curve means that low velocities won’t have
very much effect, and the difference between two
lower velocity values won’t be very noticeable.
On the other hand, high velocities produce
increasingly greater effects, and the difference between
any two higher velocity values will be more
pronounced.
Poly After Touch
Polyphonic aftertouch allows a different aftertouch
value for each note. This can be received from external
MIDI devices or generated by the internal sequencer.
The OASYS keyboard itself does not generate poly
aftertouch, however.
After Touch
This receives MIDI Aftertouch, as well as aftertouch
generated by pressing down on the OASYS keyboard.
JS X
This is the horizontal movement of the main joystick. It
also receives MIDI Pitchbend.
JS+Y (CC#01)
This is the vertical movement of the main joystick,
upwards from the center. It also receives MIDI CC#01
(mod wheel).
JS–Y (CC#02)
This is the vertical movement of the main joystick,
downwards from the center. It also receives MIDI
CC#02 (breath controller).
JS +Y & AT/2 (Joy Stick +Y & After Touch/2)
The effect will be controlled by the joystick +Y (Vertical
upward) and by after touch. In this case, the effect of
after touch will be only half of the specified intensity.
JS –Y & AT/2 (Joy Stick –Y & After Touch/2)
The effect will be controlled by the joystick –Y (Vertical
downward) and by after touch. In this case, the effect
of after touch will be only half of the specified
intensity.
Foot Pedal (CC#04)
This AMS source receives MIDI CC#04. It can also be
generated by a foot pedal connected to the rear-panel
ASSIGNABLE PEDAL input, if the Global Foot Pedal
Assign parameter is set to Foot Pedal (CC#04). For
more information, see “Foot Pedal Assignments” on
page 982.
Ribbon (CC#16)
This is the side-to-side movement of the ribbon
controller, which corresponds to MIDI CC#16.
Value Slider (CC#18)
You can use the value slider as a modulation source,
but only when the following are true:
• You’re on the Program mode P0-Main page, and
the big Program name is selected, or
• You’re on the Combination mode P0– Prog
Select/Mixer page, and the big Combination name
is selected.
In these cases only, the value slider sends MIDI CC#18,
and can be used as a modulation source.
Knob Mod.5 (CC#17)
This AMS source always responds to MIDI CC#17. A
MIDI value of 0 (far left) causes the maximum negative
modulation; 64 (center) means no modulation; and 127
(far right) causes the maximum positive modulation.
(You can invert this response, if desired, by using a
negative AMS intensity.)
It also usually corresponds to Knob 5 (USER 1) on the
Control surface- but this depends on the Modulation
Knob Assign settings for each individual Program,
Combi, and Song.
Basically, there are two separate things: a physical
knob named Knob 5, and an AMS source named
named “Knob Mod.5 (CC#17).” This provides a great
deal of flexibility–but’s it’s also easy to link the two
together. To do so:
1. Go to the current mode’s Controllers page.
2. Set Knob 5’s Modulation Knob Assign to Knob
Mod.5 (CC#17).
For more information, see “1–8: Set Up Controllers” on
page 45, and “Realtime Knobs 5–8 Assignments” on
page 980.
Knob Mod.6 (CC#19)
This AMS source always responds to MIDI CC#19, and
will usually also correspond to Knob 6 (USER 2). For
more information, see “Knob Mod.5 (CC#17)” on
page 967.
Knob Mod.7 (CC#20)
This AMS source always responds to MIDI CC#20, and
will usually also correspond to Knob 7 (USER 3). For
more information, see “Knob Mod.5 (CC#17)” on
page 967.
