Organ Flutes (Psr-740) - Yamaha Portatone PSR-640 Owner's Manual

Organ Flutes
The Organ Flutes function lets you create your own original organ voices, just as on a traditional organ,
by increasing and decreasing the flute footages, and adding percussive sounds.
Your original organ voice is stored to voice number 761 (Organ Flutes) for selecting and playing.
Parameters
Organ Type
This determines the type of organ sound or tone generation to be simulated:
Sine or Vintage. The vibrato-enhanced variations provide different modulation
effects.
Settings:
• SINE1
• SINE2
• SINE3
• SINE4
• VINTAGE1
• VINTAGE2
• VINTAGE3
• VINTAGE4
Vibrato Speed
This determines the speed of the vibrato effect (when one of the vibrato-
enhanced Organ Types is selected).
Attack Mode
This determines how the attack (or percussive) sound is applied to the organ
flutes: First or Each. When this is set to FIRST, the attack sound will only be
applied to the first note in a chord or a held group of notes. When this is set to
EACH, the attack sound will be applied equally to all notes.
Attack Footage
This determines the level of each volume in the percussive portion of the voice.
Footage settings are 4', 2-2/3', and 2'.
Length
This determines the decay of the attack sound, or how long the attack portion of
the sound sustains. The higher the value, the longer the decay.
Response
This parameter affects the sustain portion of the organ flutes, increasing or
decreasing the response time of the initial swell and release, based on the
FOOTAGE parameter (below). The higher the value, the slower the swell and
release.
Footage
The footage settings determine the basic sound of the organ flutes.
The term "footage" is a reference to the sound generation of traditional pipe
organs, in which the sound is produced by pipes of different lengths (in feet).
The longer the pipe, the lower the pitch of the sound. Hence, the 16' setting
determines the lowest pitched component of the voice, while the 1' setting
determines the highest pitched component. The higher the value of the setting,
the greater the volume of the corresponding footage. Mixing various volumes of
the footages lets you create your own distinctive organ sounds.
