Page 2: Oscillator basic/Oscillator 2 relative

Here you can select the basic oscillator type: i.e.,
whether the program will use one or two oscillators, or
a drum kit. You can also specify whether the sound of
the program will be maintained even after a Note-off
message is received, and whether the program will
sound monophonically or polyphonically.
Oscillator type
Assign
OSC2 transpose
OSC2 detune
Oscillator type
[SINGLE, DOUBLE, DRUMS]
This parameter determines the basic structure of the
program.
SINGLE (single oscillator program) will cause the pro-
gram to use only one oscillator. Maximum polyphony
will be 32 notes.
DOUBLE (double oscillator program) will cause the
program to use two oscillators. This allows more com-
plex sounds to be created, but the maximum polyph-
ony will be limited to 16 notes.
DRUMS (drum program) will assign a drum kit
(instead of a multisample) to the program. (For details
refer to the explanation for the Multisample/Drum Kit
parameter which follows later.)
Assign
[MONO, POLY]
This specifies the number of simultaneous notes that
the program will sound in response to Note messages
received on one MIDI channel.
MONO will cause the program to sound only one note
at a time.
POLY will allow the program to play chords.
Hold
OSC2 delay
Hold
[HOLD, NORM]
This specifies whether or not a note sounded by the
program will stop when you release the iS35's key-
board or when a Note-off message is received.
HOLD causes the sound to continue sounding even
after the note is released. This is convenient when
playing drum sounds. For other types of program you
will usually set this parameter to NORM.
Even with a setting of NORM, the sound will continue
playing forever if the VDA EG Sustain Level parame-
ter ( P. 181) is set to a value other than 0.
Iv (OSC2 Interval)
[–12...+12]
This parameter raises or lowers the OSC2 pitch rela-
tive to the OSC1 pitch, allowing a program to sound a
two-note parallel "chord" for each note. This can be
adjusted in semitone steps over a maximum range of 1
octave.
Positive (+) values will raise the OSC2 pitch, and neg-
ative (–) values will lower the OSC2 pitch.
Det (OSC2 Detune)
[–50...+50]
This parameter detunes OSC1 and OSC2 in relation to
each other, producing a richer sound.
Positive (+) values will cause the OSC2 pitch to rise
and the OSC1 pitch to fall, and negative (–) values will
produce the opposite effect.
This setting indicates the pitch difference between
OSC1 and OSC2 in one-cent steps, and as shown by
the following table, raising the pitch of one oscillator
will lower the pitch of the other.
