One of the most useful and exciting features of the A6 is its ability to mix sound
signals in a multitude of ways. Having a wide choice of audio paths – routes that the

oscillators and other sound sources can take as they make their way through the A6 –
provides another set of power tools that you can use to create sounds.

The 

, 

 and 

 are modules used to blend the A6’s

sound for the Programs. 

 is also important when setting the levels of

different Mix Channels in Mix Mode. But for now, we’ll focus our efforts on Program
functions.

The 

 and 

 modules are used in conjunction to mix the

levels of the A6’s sound sources, the Ring Modulator of each voice, and the two
Filters. 

 controls the A6’s sound sources going into the Filters and 

 handles the Filter outputs plus several unfiltered signals going into the

VCA controlled by Envelope 3.

PRE FILTER MIX O

VERVIEW

The 

 module contains six knobs that control the initial output levels of

their respective sound sources before they are processed by the Filters and then have
their final output levels set in 

. It is the 

 module that you use

to mix the relative output levels of the VCOs (and add in their sub-oscillators if
desired), select and mix in a noise source or external audio (but not both), mix in
Filter Feedback, and set the level of the Ring Modulator. All of these sound elements
can be mixed into a Program at the same time.

You can route the “output” of 

 – any combination of the VCOs (

and 

) plus their sub-oscillators (

), the Ring Modulator (

),

Noise/External Audio (

) and 

 from the 

 –

in a number of different ways:

• into 

 only

• into 

 only

• into both Filters in parallel – each Filter processes the 

 signal

independently and at the same time

• into both Filters in series – the output of 

 goes first into 

,

then into 

, effectively permitting the “filtering of a filter”

The Ring Modulator is especially interesting in that you can route it into the Filters as

above, bypass the Filters altogether (it has a direct route into 

) or have

both the Filtered and unfiltered signals at once. See the topic on the following page
for the complete story.

Note that all audio sources are available at the same time, with the exception of
Noise or External audio – you must select one or the other.

In addition, each level control in the 

 has its own 

 button for

controlling levels from any of the modulation sources. You can modulate the levels
of the VCOs and their sub-oscillators, the level of the Ring Modulator and the level of
the Noise Generator/External Inputs.
