How to use the Performance View

Like the Library View, it shows the Articulation List and Articulation Options - please see these articles for details about those two UI areas.

The left of the Performance View holds an area that displays relevant articulation-specific controls. These can be Variations (for example different vibrato styles), Tempo Controls, etc.

These elements will only show up if an articulation that needs/supports them is selected.

Variations are different sets of base samples for the same articulation. The most prominent example is vibrato style.

Move the Variations Slider with the mouse or use the assigned MIDI CC to switch between the possible Variations.

In the middle of the Performance View is the Articulation Grid. Here, one articulation at a time is selected per instrument. This selection can happen via Key Switches, MIDI CC values, or Program Changes. See Articulation List of details about how to map these modes.

The Performance Articulations let you switch and morph between a stack of articulations on the fly while playing. 

At the bottom of the Performance View you will find the Virtual Keyboard.

It shows the Playable range of the currently editable articulation (the articulation marked with a dot in the Articulation List), all active Key Switches and shows representations of the Pitch Wheel and Mod Wheel.

The Virtual Keyboard is velocity-sensitive: Play closer to the upper part to trigger softer velocities, closer to the bottom end of a key to trigger high velocities.

If you wish to use your computer keyboard to play the virtual keyboard, Click on the keyboard, and the ASDFGHJKL keys will play white keys, while WE TYU OP will play black keys. This computer keyboard will start on C4. Keep in mind, it is possible your computer keyboard will not be taken as a Midi controller by your DAW and will not record what you play with it. 

The Playable Range (e.g. the range the current articulations sound in) is displayed by white keys on the Virtual Keyboard. You can use the <> marker in the middle to shift it and drag the left and right edge to change the lower and upper end. Note that extreme range extensions will sound less than pleasant.

If the current instrument has multiple articulations loaded, and is set to react to Key Switches, these are displayed in a brown color in the Virtual Keyboard. You can use the <> marker in the middle to shift the Key Switch range. Note that this change will only influence the current instrument; if you want to change the Key Switches globally, it is best to change the setting in the Options View.
