Roland Piano Saving Patches You’ve Created Write, Cautions When Using a One-shot Waveform

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.

Creating a Patch

Saving Patches You’ve Created (Write)

Changes you make to sound settings are temporary, and will be lost	Patch
if you turn off the power or select another sound. If you want to keep
the modified sound, you must save it in the internal USER group	a
(user memory)
	Creating
When you modify the settings of a patch, the PATCH PLAY screen
will indicate “EDITED.” Once you save the patch into internal
memory (user memory), the “EDITED” indication goes away.

When you perform the save procedure, the data that previously occupied the save destination will be lost. However, the factory setting data can be recovered by performing the Initialization procedure (p. 43).

1.Make sure that the patch you wish to save is selected.

2.Press [MENU].

The Menu window appears.

3. Press or to select a “Patch Edit,” and then press [8

(Select)].

The Patch Edit screen appears.

4.Press [6 (Write)].

The Patch Write window appears.
