Volume: VDA (ampliﬁer)
The VDA allows you to adjust volume. The "volume" referenced here is not the volume of the
entire performance, but the volume changes within a sound. For example, the volume of the piano
sound starts with a high attack level, then drops gradually. The organ sound volume does not
change until you release the key, while the violin volume varies depending on performance
technique. The VDA allows you to edit such changes in volume.
EG and MG
The X5DR provides EGs (Envelope Generator) and MGs (Modulation Generator), which are used
to add changes over time (or in cycles) to the pitch, tone, and volume.
This allows you to add changes over time to a sound. The X5DR has Pitch EGs, VDF EGs, and
VDA EGs, which are available for editing pitch, tone, and volume, respectively. For example,
adjusting the VDA involves determining how the volume changes over time by the VDA EG.
This allows you to add cyclical changes to the sound. The X5DR utilizes Pitch MGs and VDF
MGs, which are available for editing pitch and tone. The Pitch MG allows you to add cyclical
changes in pitch (vibrato or pitch modulation); VDF MG will add cyclical changes in tone (wah
or VDF Cutoff modulation).
Volume drops gradually
The level does not change until
you release the key.
