The vertical arrows represent possible modulation routings to the basic signal path.
Instrument
This is the sampled sound wave. The pitch of the instrument can be modulated by any modulation source. The sample start point can only be modulated by a velocity or key source (see the next page).
Tone
Tone is a simple low-pass tone control which can be used to darken the sound. Tone can only be set at Note-On time (see the next page). Key velocity is commonly used to modulate the tone (in a negative way) so that the harder you play, the brighter the sound becomes.
Z-Plane Filter
The Z-Plane Filter controls the harmonic content of an instrument in a highly controlled manner. Any modulation source can be used to control the various aspects of this complex filter.
DCA
Digitally Controlled Amplifier. Together with the Alternate Volume AHDSR, the DCA is used to shape the volume contour of a sound. The DCA can be controlled by any modulation source. Key Velocity is often used as a modulation source for the DCA so that the harder you play, the louder the sound becomes.
Pan
Adjusts the balance of sound between the left and right channels.

NOTE-ON MODULATION CONTROL
Modulation sources must be connected to a destination in order to have any effect. The diagram and the LCD screen above show how modulation sources are connected to destinations. The modulation sources can control any of the destinations indicated by the small arrows.
▼ Note-On modulation sources are only measured once at Note-On time, hence the name. Even a controller like the Pitch Wheel is only measured once (at note-on time) when routed as a Note-On control. The Realtime Modulation screen (on the next page), allows continuous variation.
The possible modulation routings are completely flexible as shown in the diagram above. Multiple sources can control the same destination, or a single source can control multiple destinations.

REALTIME MODULATION CONTROL
Realtime modulation sources are parameters which can be continuously varied over time. The velocity and keyboard modulations, in comparison, are set at the key depression. Modulation sources must be connected to a destination in order to have any effect.
The diagram and the LCD screen above show how modulation sources are connected to destinations. The modulation sources can control any of the destinations indicated by the small arrows. The possible modulation routings are completely flexible as shown in the diagram above. Multiple sources can control the same destination, or a single source can control multiple destinations.

KEY NUMBER
The Key Number is affected by the Keyboard Center parameter which can be set to any key from A-1 to C7. The keyboard center establishes a reference point for keyboard modulation; keys above this point will have a positive value, while keys below it will be negative. For example, if we wished to change the volume of an instrument using key number and the key center were set to key A1, the instrument would get progressively louder above A1 and progressively softer below A1.

VELOCITY CURVES
Incoming velocity values can be scaled by one of the four velocity curves or by one of the eight Global velocity curves in order to match your playing style or better adapt to the MIDI controller. Experiment with the curves to find the one that works best for your style and MIDI controller.
