Overall System Structure
If we now put all four elements together, and add in the all-important control and effect blocks, the
system looks something like this:
In this diagram note that the KEYBOARD, CONTROLLERS & LFO block affects the PITCH,
FILTER, and AMPLITUDE stages of each element, as well as the EFFECT block.
KEYBOARD, CONTROLLERS & LFO
The EX5 and EX7 keyboards include both initial and aftertouch response which can be used for
realtime control of an extremely wide range of parameters. The EX5R does not have a keyboard,
but it accepts corresponding MIDI data from an external device which can be used to the same
effect. The extremely versatile realtime control assignment system allows just about any controller
to be assigned to any parameter — or multiple parameters, as required — for extraordinary
expressive control. The LFO (in some elements multiple LFOs) can be used for pitch, filter, and/or
amplitude modulation.
CONTROLLER parameter details begin on page 103.
EFFECTS
The EX internal effect system provides an extensive range of programmable effects including
natural reverberation, modulation effects such as chorus and flanging, compression, distortion,
auto-wah, rotary speaker, and much, much more. Controllers can also be assigned to specific effect
parameters for unlimited realtime effect variation.
EFFECT parameter details begin on page 105.
FDSP ELEMENTS
The structure of FDSP elements is just slightly different from those shown above with the addition
of an FDSP stage between the basic AWM element and effect block. The FDSP parameters are
available via the FDSP parameter page which is accessible via the COM (COMMON) parameter
page.
FDSP parameter details begin on page 123.
