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.
QSR 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 QSR Program.

When editing a Program, check the upper-middle section of the display (SND) to
determine which sound layer you are editing.
