5 VA Voice Edit
Editing VA voices becomes possible with EL-900m.
The available parameters are the same as the ones on AWM.
NOTE:
You need to understand the functions of
each parameter to edit the VA voices.
OL (Output Level)
Determines the level of the VA sound.
Range: 0 - 127
AR (Attack Rate)
Determines how quickly the Operator will reach its maximum level after the key is played.
Lower values produce a slower attack.
Range: -64 - +63
DR (Decay Rate)
Determines how much time it takes for the Operator to reach its second level.
Range: -64 - +63
RR (Release Rate)
Determines how much time it takes for the level to reach 0 after the key is released.
Range: -64 - +63
LOW
Determines to boost or decrease the output of the lower range of the keyboard.
Range: -64 - +63
HIGH
Determines to boost or decrease the output of the higher range of the keyboard.
Range: -64 - +63
The basic concept and necessary operations are the same as the ones for AWM
voice editing.
As you can see the algorithm, a VA voice is configured with three factors: VA,
AWM and FM.
However, the output levels of AWM and FM tone generators are set to off, and
VA voices sound using VA tone generator only. (This is true for all VA voices.)
You can edit the VA voices adding AWM and/or FM voice elements. Now listen
to the "hidden" voices by raising the AWM and/or FM output levels.
NOTE:
Some voices may not have distinctive
effect.
NOTE:
The VA voices built in EL-900 are also
configured with VA, AWM and FM.
