messages from your sequencer (one for each channel) for every note; a layered
program would need only one Note On message.
When layers of a Program are designed to be used together, and the
individual layers by themselves wouldn't be used alone (for example, the
percussion layer of the organ sound).
Use Mix Play Mode:
When you want to layer more than four voices. In Mix Play Mode, it is
possible (though not advisable) to stack all 64 voices onto a single key.
When each sound is likely to be used by itself by other setups. For
example, if you are programming three different keyboard splits, each of which
uses the same left-hand bass patch, it makes sense to use Mix Play Mode.
When you want different sounds to respond to different MIDI channels.
QuadraSynth Plus Signal Flow

The Four Sounds of a Program

Each Program is made up of at least one to four sounds. A sound is
made up of several components including a voice (the original sound
material) which passes through a low-pass filter and an amplifier. The
voice, filter and amp modules each have direct modifiers (Pitch LFO,
Filter LFO, Amp Envelope) which affect how each will function in the
Program. You can layer these sounds together, or divide them into
regions of the keyboard, or a combination of these things.
The following diagram illustrates the signal flow within each
QuadraSynth Plus Program.
