● Amplitude
This unit controls the output level (amplitude) of the sound
output from Filter. The signals are then sent at this level to the
Effect block. Also, by setting the AEG (Amplitude Envelope
Generator), you can control how the volume changes over time.
AEG (Amplitude Envelope Generator)
Using the AEG, you can control the transition in volume from
the moment the sound starts is to the moment the sound
stops. You can create the AEG by setting parameters as
illustrated below. When you press a note on the keyboard, the
volume will change according to these envelope settings.
Furthermore, different AEG parameters can be set for each
Element Key.
n When you release the key while holding the Footswitch connected to
the SUSTAIN connector, the sound will maintain at the Sustain Level
shown above. For Voices having a Sustain Level value greater than 0,
the sound continues. For Voices having a Sustain Level of 0, the
sound decays naturally to silence.
● LFO (Low Frequency Oscillator)
As its name suggests, the LFO produces a wave of a low
frequency.
These waves can be used to vary the pitch, filter or amplitude
of each Element to create effects such as vibrato, wah and
tremolo. LFO can be set independently for each Element; it
can also be set globally for all Elements.
Single Timbre Tone Generator (Voice/
Performance mode) and Multi-timbral
Tone Generator (Song/Pattern mode)
The internal tone generator block operates in two different
ways (Single timbre and Multi-timbral) depending on the
selected mode. The difference between the two is whether
they can handle the multi-MIDI channels or not at the same
time.
●
Single Timbre Tone Generator (Voice/Performance mode)
A MIDI tone generator that receives over a single MIDI
channel and plays a single instrument part is referred to as a
“single timbre” tone generator. This is the operating status of
the internal tone generator in the Voice and Performance
modes.
n To set the MIDI receive channel for single timbre operation (Voice and
Performance modes), use the following operation in the Utility mode.
[UTILITY] → [F5] MIDI → [SF1] CH → BasicRcvCh
● Multi-timbral Tone Generator (Song/Pattern mode)
A MIDI tone generator that simultaneously receives over
multiple MIDI channels and plays multiple instrument parts is
referred to as a “multi-timbral” tone generator. This allows
playback of multi-channel MIDI song data — such as on a
MIDI sequencer or computer — with each internal part being
assigned to and played by a different track or channel. This
is the operating status of the internal tone generator in the
Song and Pattern modes.
n To set the MIDI receive channel for multi-timbral operation (Song and
Pattern modes), use the following operation in the Utility mode.
[SONG] or [PATTERN] → [MIXING] → [EDIT] → Part selection → [F1]
VOICE → [SF2] MODE → ReceiveCh
n When using an external MIDI sequencer or computer to play this
instrument, make sure to use the Song mode or Pattern mode.
Maximum Polyphony
Maximum polyphony refers to the highest number of notes
that can be sounded simultaneously from the internal tone
generator of the instrument.
The maximum polyphony of this synthesizer is 128. When
the internal tone generator block receives a number of
notes exceeding the maximum polyphony, previously
played notes are cut off. Keep in mind this may be
especially noticeable with Voices not having decay.
Furthermore, the maximum polyphony applies to the
number of voice elements used, not the number of voices.
When the normal voices that include up to four elements
are used, the maximum number of simultaneous notes
may be less than 128.
n When the Plug-in board is installed, the maximum polyphony
increases accordingly. For details on maximum polyphony for
the Plug-in Boards, refer to the Owner’s Manual of the
particular board.
