1
LEDs
The LEDs
1
indicate the frequency of the internal
LFOs. They indicate the state of the
sawtooth
signal
at output
S0
and/or the
triangle
wave at output
T0
.

Freq. –
Buttons
2
and
3
have a double function in the MIDI-
CV interface:
•
Setting LFO frequency
Pressing buttons
2
or
3
increases
and/or
de-
creases
the
frequency
of the internal LFOs.
While buttons
2
or
3
are pressed,
LEDs
5
and
6
blink to show the increase or decrease in the LFO
frequency. If you reach the upper or lower limit of
the frequency, the LED stops blinking.

It’s easier and definitely
more precise
to
alter the LFO frequency
by MIDI controller
#92
.
Setting the MIDI input channel
If you simultaneously hold down buttons
2
and
3
,
"
learning mode
" is activated. This is signalled by
LEDs
5
,
6
and
8
all flashing at once.
You can now set the MIDI channel you want the
MCV16 to respond to. To do this, send a valid
MIDI
controller
(see table 1) to the A-191. This automati-
cally ends learning mode, the LEDs go out, and the
MIDI channel of whatever controller was used beco-
mes the input channel for all the MIDI data sent after
this.
LFO frequency and MIDI- input channel are only tem-
porarily stored, unless you save them by pressing
button
9
(see below).

The labels on LEDs
5
and
6
("Fast", "Slow",
"--") don’t have a function yet in MIDI-CV
mode, but are hoped to have in a future
update.

LEDs
5
,
6
and

light for about a second to confirm
the save procedure has succeeded. At the same time,
all CV outputs are set to their default settings (see
table 1).
