Sequential Split-Eight - User Manual

Announcing The Split-Eight,
Sequential^ New 8-Voice Programmable Synthesizer!
The Split-Eight is a fully programmable eight voice
synthesizer featuring a full 5-octave keyboard and
programmable keyboard split for $1,195.00 suggested retail.
And that's just the beginning!
For instance, The Split-Eight offers a choice of four
keyboard modes: Single, Unison, Double or Split. In Single
Mode, the same sound is played across the length of the
five-octave keyboard. This provides the user with eight full
voices for traditional polyphonic playing. Unison mode
assigns all eight voices to a single note, creating a very full,
bold sound ideal for lead synth playing.
Double mode lets the user layer different sounds on top
of each other. In this way, two sounds are triggered by each
key to create complex sounds utilizing the full programming
capabilities of two independent oscillators, filters, and VGA's
at one time.
The exciting Split Mode is particularly useful in
performance, because it lets the user play different sounds
at each end of the keyboard (such as playing a bass sound
with the left hand and a flute with the right)! The split
point can be programmed. When in Split Mode, the
instrument automatically assigns four voices to each side of
the split point. The Split-Eight also features a programmable
link feature which lets you call up Split or Double programs
simultaneously.
The fully programmable Split-Eight comes with 64 pre
programmed sounds, including a variety of original sounds
and several impressive orchestral and keyboard timbres. All
sounds can be easily modified or replaced with custom
sounds.
A built-in chorus provides programmable on/off
chorusing.
The Technical Stuff
Each of the instrument's eight voices feature a multi-
waveform VCO, a 4-pole lowpass filter, a VCA, two ADSR
envelope generators and an LFO. The Split-Eight comes with
64 pre-programmed sounds.
Creating custom sounds is easy! There is a graphic matrix
which allows fast selection and easy editing of 31 different
parameters. LEDs clearly indicate the selected program, and
if the program is being edited, will also display the
parameter value.
The back panel contains individual outputs for channels A
and B along with a 1/4" main output that gives you the
chorus mix. Cassette In and Out, a multi-purpose
footswitch, and MIDI Input and Output are also included.
Sequential supports the Split-Eight with an extensive array
of MIDI functions. Modes 1 and 3 (Omni and Poly) are
available along with the ability to disengage MIDI. Each side
of a split program may be assigned to a separate MIDI
channel. This allows the user to control other MIDI
keyboards independently with each side of the keyboard.
Through MIDI, the Split-Eight can send and receive program
change information, and transfer programs to and from a
second Split-Eight. Other MIDI features include the ability
to receive and send pitch bend and modulation information.
