3. Switching between the functions
Because the A-191 has two separate functions in it,
which share some of the controls and outputs, at any
one time it can be used
either
as a MIDI-CV interface
or
as a Shepard Generator. To switch between the two
you simply press a button (see below).

The A-191’s controls and in / outputs for
each function are explained in their
respective sections of this manual.

4. MIDI-CV interface
4.1 Basics
In its MIDI-CV mode, the A-191 provides a MIDI-CV
converter, and a MIDI-synchronized LFO.
Whenever the A-191 receives
relevant MIDI control-
ler messages
on the channel you’ve selected, it con-
verts them into control voltages (in a 0 V to +5 V
range), and sends these out on the corresponding CV
outputs. Table 1 on page 4 lists the MIDI controllers,
their corresponding CV output sockets, and their de-
fault values.

After switching your A-100 system on, pres-
sing the
Store/Reset button

sets the
voltages at the
CV outputs
to the
default
values
(see table 1).
If you’re running your A-100 from a MIDI
sequencer, you’ll need to save the appro-
priate MIDI controller messages at the begin-
ning of a Song, to initialise the A-191’s CV
outputs correctly.
