TRANSPOSE [9] Range: +/- 12 semitones
@ Overview
With the exception of the PCM percussion sounds, all Por-
taSound voices can be transposed over a range of two octaves.
In other words, you can use the TRANSPOSE function to
raise or lower the pitch of both the MELODY SECTION
and the AUTO ACCOMPANIMENT SECTION in semitone
steps.
This feature has mainly two applications. First, it lets you
set the pitch of the entire keyboard to the easiest key for you
to play in. For example, if a song is in B major and you find
it difficult to perform in that key, all you have to do is lower
the keyboard pitch by a half-tone with TRANSPOSE. Now,
if you play the same song in the easy key of C major on the
PortaSound keyboard, its pitch will automatically be trans-
posed downward (lowered) by a semitone, so that in effect
you will hear it in B major. This is sometimes handy when
playing along with other instruments, too.
TRANSPOSE can also be used to raise or lower the pitch
of the PortaSound by an octave in order to change the mood
of the music or adapt the note range to the character of the
instrument voice — e.g. transposing it downward for a deeper
and more powerful electric bass sound.
Note, however, that octave transposition is only effective for
melody voices — the auto accompaniment section returns to
original pitch when a TRANSPOSE value of + or~ 12 is
entered.
@ Operation
1, Press TRANSPOSE [9].
The TEMPO/PARAMETER & VALUE display will show
TRANSPOSE Value Display

PARAMETER & VALUE
This display tells you that the TRANSPOSE value is now
0, meaning that the keyboard is in its regular key.
2. Adjust the key with the VALUE buttons.
To raise the key, use + . Each value increase by | means
an upward transposition by 1 semitone.
— lowers the key. A minus symbol "—" in front of the
value indicates that the current key is lower than the re-
gular setting of 0.
e Press both VALUE buttons simultaneously to instantly
return to the regular key (TRANSPOSE value 0).
Points te Remember
@ The TRANSPOSE value is memorized when power is
turned off.
@ The TRANSPOSE value influences the pitch of tran-
smitted MIDI note data and received data in the 00
mode. However, received data is not affected in the
99 mode. (See MIDI section.)
TUNING [3]
Range: +/-16
@ Overview
The overall pitch of your PortaSound is normally set so that
A3 = 440 Hz (standard concert pitch). When playing together
with other instruments which have a different tuning, you
can raise or lower this pitch in steps of approximately 3.13
cents over a +/-~ 16 step range.
@ Operation
1. Press TUNING [dg].

This display tells you that the TUNING value is now 0,
meaning that A3 corresponds to 440 Hz.
2. Adjust the pitch with the VALUE buttons.
To raise the pitch, use +. Each value increase by | raises
the pitch by about 3.13 cents.
— lowers the pitch. A minus symbol "—" in front of the
value indicates that the current pitch is lower than the
regular setting.
e Press both VALUE buttons simultaneously to instantly
return to the regular pitch (TUNING value 0).
@ The TUNING value is memorized when power is turned
off.
MELODY VOLUME [35] Range: 1 — 9
@ Overview
This parameter lets you adjust the volume of the keyboard's
MELODY SECTION and the SONG MEMORY MELODY
banks in relation to the AUTO ACCOMPANIMENT sounds.
(For information on AUTO ACCOMPANIMENT, see be-
low.) Minimum value is | for the quietest, maximum is 9 for
the loudest sound.
Occasionally, chords will sound distorted if melody volume
is set to maximum and the voice has a TOTAL LEVEL (see
Digital Synthesizer section) of 90 or more. In such cases, lower
the melody volume or the total level.
