Controllers

The A6 provides all the standard hardware controllers you’d expect in a keyboard

synthesizer plus a few more. Most obvious is its 5-octave (C-to-C) semi-weighted
keyboard that responds to velocity and aftertouch. It can be played normally with
one Program across all keys, or can be split so that one Program plays from the lower
range of keys and a second Program plays from the upper range. In fact, three-way
and four-way (or more) splits are easy. In all cases, split points are user-assignable
and programmable. Also, two or more Programs can be layered, and the balance of
the Programs as well as any transposing are user-assignable and programmable.

The A6 features several keyboard performance modes under the

KBD MODE

heading.

In addition to the A6’s polyphonic (

POLY

) play mode, monophonic (

MONO

) and

unison (

UNISON X

) voicings are also available along with a wide range of Portamento

(

PORTA

) modes.

And where would we be without assignable Pitch and Modulation wheels? Notice
that the controller wheels are not specifically labeled Pitch Bend and Vibrato. That’s
because you can define each wheel as you like it using the

ASSIGN

buttons. Some of

us like the Mod wheel to be the one on the right, because in the days of hard-wiring
controllers, most manufacturers just did it that way, and we got used to it. But you
can assign Vibrato to be the one on the left, if you so desire. In fact, you can make

both wheels Pitch or both Vibrato. Or make them do something else, like

add/remove brightness, control volume level, you name it.

There are also back panel inputs for

FOOTSWITCHES AND PEDALS

. The A6’s

PEDAL/CV

(commonly used for volume) and

SUSTAIN

pedal inputs allow the use of foot

controllers for master volume control and sustain. A third input jack labeled

SWITCH

is ideally suited for footswitch control of patch changes. The electrical specifications
for these switches and pedals are listed in Appendix C: Specifications.

That long strip of fabric along the top of the keyboard is the A6’s Ribbon Controller.
Normally assigned to the VCOs’ frequency to create a pitch bend device, it can be
assigned to countless other parts of the sound.

The rear-panel

CONTROL VOLTAGE INPUTS

labeled

OSCILLATOR

and

FILTER

are the

classic control inputs from the early analog era. These inputs make controlling the

VCOs and VCFs possible from external analog devices like an analog sequencer,
guitar synth or wind controller.

The A6’s Real-time

ARPEGGIATOR

takes held chords from the keyboard and/or

incoming MIDI Notes and creates an arpeggio from the original chord. You can

arpeggiate “up” (from the lowest note being played to the highest note), “down”
(high to low), or up and down. You can also extend the range of the held notes to up
to five octaves above the actual notes being played.

Another classic analog controller is the A6’s 16-event, programmable

SEQUENCER

– a

step sequencer that takes its design right out of the pages of analog genesis. The
notes and filter settings are programmed by hand – not recorded like you’d expect

from a digital or MIDI sequencer. There’s a programmable sequence for each of the
128 Programs.

The

MASTER CLOCK

control sets the tempo for both the Arpeggiator and each

Sequence, and can be slaved to received MIDI Timing Clock.
