Overview
32 QuadraSynth Reference Manual
and by comparison, many synths sound static. Being able to layer up to four sounds
allows for creating large ensembles (e.g., brass section consisting of alto & tenor sax,
trumpet, and trombone) or extremely realistic versions of single instruments. When
creating layered Programs, keep polyphony in mind. If all Programs in a Mix use all
four available sounds, the QuadraSynth will quickly run out of voices.
Modes
The QuadraSynth is always in one of two main modes: Program mode or Mix mode.
Pressing [PROGRAM] selects Program mode, while pressing [MIX] selects Mix
mode. While in Program mode, you can use [SELECT] to access Program Edit mode
and Effects Edit mode. While in Mix Mode, pressing [SELECT] alternates between
Mix Edit mode, Program Edit mode and Effects Edit mode. Pressing [GLOBAL]
accesses Global Edit mode, pressing [COMPARE] accesses Compare mode, and
pressing [STORE] accesses Store mode. Here are descriptions of these modes:
Program Mode
Program mode lets you play the QuadraSynthÕs various Programs one at a time.
The QuadraSynth contains 128 Preset and 128 User Programs (i.e., the sounds of
various instruments, effects, ensembles, etc.) that show off just how cool this
instrument really is. Initially, both the Preset and the User Programs contain data
loaded in at the factory. The User Programs can be edited or replaced with your own
Programs. However, you cannot replace the Preset Programs, because these are
stored in ROM (permanent memory). Each Program can select any one of the 256
Effect Patches (Large Hall, Chorus, etc.). In some cases, the Program is heavily
dependent on its effect; in others, the effect is more subtle. In Program Mode, the
QuadraSynth responds to or generates messages on a single MIDI channel.
Mix Mode
Mix mode lets you audition the QuadraSynthÕs various Mixes, and use it as a MIDI
master controller. The QuadraSynth contains 100 Preset Mixes and 100 User Mixes. A
Mix can combine up to 16 different Programs, and the keyboard can generate up to
16 channels of MIDI data at once. Therefore, much thicker and richly textured sounds
can be created. In Mix mode, the QuadraSynth can be used in a wide range of
applications. It can be used for live performance, in which sounds are layered or
assigned to sections of the keyboard. It can also be used as a multitimbral sound
source for desktop music and home studio applications. Each Mix can select any one
of the 256 Effects Patches (Large Hall, Chorus, etc.). Even though there may be 16
Programs in a Mix, there can only be one Effects Patch per Mix. In Mix Mode, the
QuadraSynth can respond to messages on up to 16 MIDI channels simultaneously;
different channels are available depending on which Mix is selected.
Program Edit Mode
In Program Edit mode, you can change the various settings which determine the
sound of an individual Program, or create an entirely new Program from scratch. In
Program Edit mode you can:
¥ select which sample waveform from the 16 megabytes of onboard sample ROM
will be used, in each of the 4 sounds;
¥ change the tone, level, attack and decay characteristics, modulation inputs, and
pitch of each layer;
