Simultaneous Notes

AWM Voices

The maximum simultaneous polyphony of the EX5 and

EX5R AWM tone generator is 126 notes, and that of the

EX7 is 64 notes. This number decreases, however, as

the number of elements and layers used increases. For

example, the maximum simultaneous polyphony when a

6-element performance setup is played on the EX5 will

be 21 notes (126 ÷ 6 = 21).

FDSP Voices

As you probably already know, FDSP voices are limited

to 16-note polyphony on the EX5/5R (8-notes on the

EX7). In the Performance mode, however, you have

sufficient polyphony to use several AWM voices in

addition to one FDSP voice when creating a song.

Here's an example: Part 1 uses an FDSP voice with 2

elements. This voice will use 2x16 = 32 notes maximum

(if 16 notes are actually played at the same time - a

relatively rare occurence). In this case, you have 126 -

32 = 94 notes (or 48 on the EX7) available for additional

AWM voices in Part 2 and subsequent parts. Each

additional FDSP element will reduce the polyphony by

another 16 (or 8) notes. Again, try to limit the number of

voice elements you use in the Performance mode.

Although the EX instruments offer more than enough

simultaneous note capacity for most applications, be

aware that unnecessary elements and layers can

reduce the available number of notes significantly.

Always try to create voices and performance setups that

use the capabilities of the EX-series instruments

efficiently.

Static Control Filter

In addition to the DCF (Dynamic Control Filter)

parameters, each voice element has a range of SCF

(Static Control Filter) parameters including EQ and

filters which can be used to shape the sound of the

voice (manual page 86). The SCF parameters require a

considerable amount of processing power, however, and

can contribute to slow response. For situations in which

the fastest possible voice response is essential, it may

be better to set the SCF parameters to "Thru".

Zone Assignments & Voice Response

In the Voice Edit mode each voice element can be

assigned a note and velocity zone (manual page 82).

The note zone assignments, in particular, can affect

voice response, so a brief explanation is in order.

A graphic representation of the zone assignments for

the current voice is provided in the Voice

Edit/OSC(F2)/ZONE(F8) display.

When the full range of notes is assigned to all four

elements in a four-element voice, for example, all four

elements will sound when any single key is played so

the total polyphony is reduced to 1/4, and the

processing requirements are increased fourfold.

In the example below each element is assigned a

different range of notes and none of the zones overlap,

so only one element sounds when any single key is

played. In this case the polyphony and processing

requirements are the same as for a single-element

voice.

Element 1

Element 2

C-2

By expanding the above example it is possible to create

as many as 8 split zones on the keyboard.

It may be possible, for example, to assign more than 2

voices (which is the limit in the Performance Mode) to

the keyboard. That way you can combine 2 voices each

using up to 4 of the above zone assignments (with

limited keyboard ranges) in order to achieve the desired

results.
