Yamaha RX5 - Edit Voice

JOB #02: PITCH EDIT
FUNCTION то ater the pitch of the selected voice.
This function can be carried out on the voice that has been selected using EDIT VOICE
JOB #01.
OPERATION
1. After selecting a voice in JOB #01, select JOB #02.
EDIT VOICE :keyA
Pitch=+ бісепі
2. Use the --1/МО ага +1/YES keys or the DATA ENTRY slider to change the pitch
by semitone units. Holding the "0" key while using the -- ИМО or +1/YES key to
change pitch allows pitch change in 10-cent (1/10th semitone) units. Pitch values are
shown in 1-cent (1/100th semitone) units.
Range: +24/—36 semitones, displayed as 4 2400/— 3600 cents.
JOB #03: ENVELOPE EDIT
FUNCTION то edit the envelope generator of the selected voice.
This function can be carried out on the voice that has been selected using EDIT VOICE
JOB #01.
Each voice on the RX5 has an envelope, with six separate parameters, as shown in the
following diagram.
LEVEL
TIME -
-— 6.GT -
AR = Attack Rate (parameter 1) ГІН = Decay 1 Rate (parameter 2)
DiL = Decay 1 Level (parameter 3} ПӘН = Decay 2 Rate (parameter 4j
RR = Release Rate (parameter 5) GT = Gate Time Ce Б)
EDIT VOICE MODE
This graph indicates visually what happens to the level of a single sound. With
percussion instruments, the initial “attack” is usually very rapid — you hit the instruments,
and the sound builds to a peak almost instantly. Slower attacks (where the sound takes
a noticeable time to reach the maximum level) occur with violin, flute, the human voice,
or a cymbal played with a soft mallet.
Then a first “decay” follows as the sound drops in level, to the first “decay level". This
is followed by a second decay, and a final “release” as the sound dies away to silence.
This kind of envelope can be heard clearly in the case of а cymbal played with a hard
Stick. The sound begins instantly (a high Attack Rate). The first bright tone decays
quickly to а more muted “middle tone” as the complex harmonics of the initial impact
dissipate (high Decay 1 Rate, then a lower Decay 1 Level). The middle tone slowly
decreases in level (low Decay 2 Rate). Finally, the tail end of the sound consists of a
few lower harmonics which die away to silence (low Release Rate). And in many other
instruments, a similar envelope structure occurs, perhaps with more rapidity.
Of course, each voice on the RX5 is an accurate digital recording of a real percussion
instrument (or in some cases, a synthesizer sound) and contains its own built-in
envelope. The Envelope Edit function allows you to modify the envelope in a very natural
way, to create new, equally authentic voices.
The Gate Time indicates the overall length of the envelope, excluding the Release part
of the envelope. It can be described by comparing it to what happens in a synthesizer
such as a Yamaha DX7. When you hold a note down on a DX7, it's like opening a digital
"gate", allowing the sound to pass. Then, when you release the key, the sound dies
away gradually according to its Release Rate. So the Gate Time does NOT affect the
Release Time, but as it is decreased, it will progressively cut the Decay 2 time, then the
Decay 1 time.
Generally, increasing the attack or decay rate will shorten the attack or decay time, and
vice versa.
NOTE: If envelope settings are set so as to create a long envelope, the original sound
is usually lengthened by "Iooping" — taking a short portion of the sound and repeating
it with increasing or decreasing level, for a natural extended effect. Refer to EDIT VOICE
JOB #06 to see how to turn a loop off.
Also, the decay length cannot be setto more than 6.5 seconds (the maximum gate Time
on the RX5). Therefore, very long decays may be cut off before they have faded to
silence.
