V 1-16
The

routes a mono or single-channel external audio source to all 16 of the A6's Voices.
This means that you can process a mono signal polyphonically through the A6's
filters, complete with all of the modulation normally available to the Filters:

FILTER FEEDBACK
A little trick that was used in the days of modular synthesizers to achieve a gritty,
nasty sound was to connect the output of the filter module back into the mix module.
Since the mix module is normally routed to the filters to begin with, a feedback loop
was created. (MiniMoog users might remember this capability by connecting the
Mini's headphone output to the auxiliary audio input).
The A6 pre-wires this circuit for you internally: no patch cords required. Press the

AUDIO EXT IN
You can process external audio sources through the A6.
Examples of audio sources you can use include an electric
guitar, a high-impedance microphone, a digital sampler,
an audio CD player or cassette player, just to name a few.
You may want to process your external audio by the A6's
Filters. And since the Filters can be modulated, you can
also shape the external source by an envelope and add a
host of other mod sources if needed.
