(as they are in multiple-trigger mode). Instead, the envelope is
triggered only when all previous keys have been completely released.
This allows you to selectively accent notes by touch.
Delay
Range:00-03
00s off
01 s 20 millisecond delay
02s 40 ms
03s 80 ms
When Unison is on, use this for an interesting flange, doubling, or
echo effect.
Footswitch Accent
This parameter allows the footswitch to temporarily change the
setting of one of the following parameters:
Glide
Filter Cutoff
Filter Amount
Filter Attack
Voice Volume
Amplifier Decay
Amplifier Release
To program the footswitch:
1. Switch Preset off.
2. Hold down Record and press PROGRAM SELECT 2. The control
panel blinks, and the Glide parameter is selected.
3. To select other parameters, press the footswitch.
4. When the desired accent parameter has been
selected, press
Record again. (It stops blinking.)
5. While holding.the footswitch, adjust the Value knob for the desired
accent tone or effect. When you release the footswitch, the displayed
parameter returns to its original programmed value.
6. Switch Preset on.
7. Switch Record on. It blinks.
8. Enter the desired two-digit program number.
9.
Pressing
on
the
footswitch
temporarily
selects
the
accent
parameter value.
Footswitch Sub-program
If the accent feature is not used or desired, you can program the
footswitch to temporarily switch to a new program:
1. Switch Preset on.
2. Hold down Record and press PROGRAM SELECT 2. (Blinking
starts.)
3. Enter two digits for sub-program number. (Blinking stops.)
4. Press the footswitch.
5. Pressing the footswitch alternately selects the main program and
the subprogram.

SYNTHESIZER PARAMETERS
This
section
describes
the
Split-Eight's
programmable
voice
parameters.
The Split-Eight actually contains eight synthesizers, termed "voices."
Figure 1 diagrams one of these voices at a very general level. The
Split-Eight
fits
into
the
tradition
of
voltage-controlled
analog
synthesizers. To understand these instruments it has proven useful to
identify
three
basic
functions:
controllers,
audio
sources,
and
modifiers (filters and amplifiers). Each voice contains several of each
type of function.
Basically, controllers provide
the
control
voltages (CVs) which
determine
the
pitch
of
the audio
sources, or
the
filtering
or
attenuation effects of the modifiers. Controllers can be mechanical
devices such as keyboards and wheels. For example, as the CV from
the
keyboard
to
the
oscillator (audio source) is increased, the
oscillator frequency increases. Or controllers can be electronic, such
as the LFO or the two envelope generators. For example, as a
rapidly-decreasing CV from an envelope generator sweeps down the
the filter cutoff frequency, it imparts a "pluck" to the voice. Other
controllers include The MASTER TUNE knob and PITCH wheel, which
in effect provide two CVs which control all of the oscillators.
There are two audio sources: the oscillator,
and the filter,
if it is
adjusted for self-resonance.
The mixer, filter (when not in self-resonance), and amplifier are
modifiers.
A more detailed examination of the voice parameters follows.
