Cautions When Using a One-shot Waveform

It is not possible to use the envelope to modify a one-shot waveform to create a decay that is longer than the original waveform, or to turn it into a sustaining sound. If you were to program such an envelope, you would be attempting to shape a portion of the sound that simply doesn’t exist, and the envelope would have no effect.

Cautions When Using a Loop

Waveform

With many acoustic instruments such as piano and sax, extreme timbral changes occur during the first few moments of each note. This initial attack is what defines much of the instrument’s character. For such waveforms, it is best to use the complex tonal changes of the attack portion of the waveform just as they are, and to use the envelope only to modify the decay portion. If you attempt to use the envelope to modify the attack portion as well, the characteristics of the original waveform may prevent you from getting the sound that you intend.

Chapter 5. Creating Patches

Functions of Patch

Parameters

This section explains the functions the different Patch parameters have, as well as the composition of these parameters.

Parameters marked with a can be controlled using specified MIDI messages (Matrix Controller). Settings in the Matrix Control page will determine how these parameters are controlled (p. 78, p. 79).

Settings Common to the Entire Patch (COMMON)

On this display you can assign a name to a Patch and set the volume and pan of the entire Patch.

PATCH NAME

You can assign a name of up to 12 characters to the Patch.

For details on assigning names, refer to “Assigning a Name” (p. 28).

PATCH CATEGORY

Category (Patch Category)

Specifies the type (category) of the Patch.

The Patch Finder function uses this setting. It also determines the phrase that will be sounded when using the Phrase Preview function.

For details on the possible category names, refer to (p. 31).
