To select a Program, move the cursor to the Program Number field and use
the data knob to choose the desired Program.
If the Program Mode Main Screen is displayed and MIDI Program Changes
are enabled in the SYSTEM menu, a MIDI Program Change command of 1–
50 will select the corresponding Program.
If the Program Mode Main Screen is displayed and the Foot Switch is set to
STEP in the SYSTEM menu, pressing the foot switch will step to the next
higher numbered Program.
To move to Song Mode (see below), move the cursor to the top line and
use the data knob to select Song Mode.
Song Mode Main Screen
When in Song Mode, this Main Screen appears as follows:
Song:XXaaaaaaaaaaaaa
Step:YYbbbbbbbbbbbbb
where XX is the song number, aaaaaaaaaaaaa is the song name, YY is the
Song Step number and bbbbbbbbbbbbb displays the name of the Program
or navigation message at Step YY.
To select a Song, move the cursor to the Song Number field and use the
data knob to choose the desired Song.
If the Song Mode Main Screen is displayed and MIDI Program Changes are
enabled in the SYSTEM menu, a MIDI Program Change command of 1–20
will select the corresponding Song.
If the Song Mode Main Screen is displayed and the Foot Switch is set to
STEP in the SYSTEM menu, pressing the Foot Switch will step to the next
non-”0 Song Step in the Song’s Step list.
When in Song Mode, the Speed and Vibrato settings programmed for the
selected Song override the Speed and Vibrato settings in any Programs
called up by Song Steps. 
						

							22
Each Song Step must contain one of the following items:
ITEM CODE MAIN SCREEN STEP DISPLAY
0 (no program)
## (Program number) the program name
B (B bypass)
 link)
Please note:In the Song Mode main screen, the Cursor buttons can be used to move
the cursor to the YY field and the data knob can then be used to select
any Song Step and display the item programmed for that step. How-
ever, when the MIDI increment message or the foot switch step func-
tions are used, the Song Steps may not necessarily appear sequentially.
Any steps programmed with zeroes are skipped, and the control func-
tions ( and E) will cause changes in Song Step recall order.
For details on the function of each of these options, see the section on
programming Songs on page 26.
To move to Program Mode, move the cursor to the word SONG on the top
line of the Main Screen and use the data knob to select Program Mode.
Program Edit Pages
Pressing the PROGRAMS button while the Program Mode Main Screen is
displayed will place the ATR-1a in Program Edit Mode. The fields on these
pages allow you to set the parameters which control the ATR-1a pitch
processing algorithm.
To edit a specific Program you must first select that Program as the current
Program. Do that by calling up the appropriate program number on the
Program Mode Main Screen. Then, press the PROGRAMS button (the red
LED under the PROGRAMS button will light). The number of the Program
being edited will always appear in the top left corner of the various
Program Edit pages.
When editing a Program, you progress from one edit page to the next by
pressing the PAGE button.
When you are finished making changes, press the PROGRAMS button
again. You will be prompted to save the changes (see the Save Program
Page, below). 
						

							23
Speed Page
The first edit page displayed is the SPEED page:
Program:XX Speed
(0 is fast): yy
The SPEED control determines how rapidly pitch correction is applied to
the incoming sound. Values range from 0 to 25. A value of zero will cause
instantaneous changes from one tone to another and will completely
suppress a vibrato and any purposeful expressive pitch variations (note
that any related volume changes will remain). Values from 6 to 10 are
typical for vocals. Higher values allow more vibrato and other interpreta-
tive pitch gestures, but will slow down the rate at which pitch corrections
are made.
Although the above suggestions can be used as starting points, finding
the correct Speed setting for a particular performance is largely a matter
of trial-and-error and depends on such attributes as song tempo, note
duration and vocal style, among others.
Make Scale From MIDI Page
In most cases, you will probably tell the ATR-1a which notes to correct
using the Scale Page described below. However, there may be occasions
when it is not clear exactly what key a melody line is in, or where the line
has too many accidentals to fit comfortably into a conventional scale. For
those occasions, the Make Scale From MIDI function allows you to simply
play the line into the ATR-1a from a MIDI keyboard or sequencer and let
the ATR-1a  construct a custom scale containing only those notes that
appear in the line.
Prog:xx  Press < to
make scale from MIDI
To use the Make Scale From MIDI function, ensure that your MIDI source is
connected to the ATR-1a’s MIDI input and is transmitting on the same MIDI
channel specified on MIDI Page 1 in the System Edit section. Then press the
left cursor button to begin the process. The following screen is displayed:
xx:
Press PAGE when done 
						

							24
Now simply play the melody to be corrected from your keyboard or
sequencer. Tempo and rhythm don’t matter, so take your time and make
sure you don’t play any wrong notes. As each note is played, its name
appears in the top line of the display. Assume, for example, that your
melody starts with D

, B, and then A. After playing those notes the display
would look like this:
xx:    D#       A  B
Press PAGE when done
When you have played the entire melody, press the PAGE button to end
the process and automatically take you to the Scale Page, where you may
further edit your scale as described below.
If you happen to make an error during note entry, or want to try again for
any other reason, continue pressing the PAGE button until you return to
the first screen above and start the process again.
Note:When you start the process by pressing the left cursor key, all notes are
first removed from the current Program’s scale in preparation for
adding just the notes you play. If you then press the PAGE button
without playing any notes, you will be taken to the Scale Page below
which will display a scale with no notes present. In this state, the ATR-1a
will pass all notes with no correction applied. So don’t do that.
Another Note:We realize that there is some possibility of confusion between the
Make Scale From MIDI function and MIDI Note Mode selected on MIDI
Page 1 in the System Edit pages. To clarify: the MIDI Note Mode is used
to specify target pitches in real time while pitch correction is occurring,
while Make Scale From MIDI is used in advance of correction to create a
custom scale for a program.
MIDI Note Mode does not need to (and, in fact, shouldn’t) be enabled
to use the Make Scale From MIDI function. MIDI Note Mode always
overrides the current program’s scale, including one created by the
Make Scale From MIDI function.
Scale Page
You tell the ATR-1a exactly which notes you want to correct on the Scale
Page:
XX:CC#DD#EFF#GG#AA#B
By: 
						

							25
This page allows you to specify the scale notes to which the ATR-1a tunes
the input sound. If you have used the Make Scale From MIDI function
described above, the notes input via MIDI will already appear on the page
and can be further edited here. There are 12 notes in this scale, i.e. C, C #,
…etc. Each note in the scale can be set to one of three states:
Tune (i.e., the note name appears in the display, but the “By:” field under
the note is blank): When the input is near a note set to Tune, the ATR-1a
will retune the input to that note.
Bypass (i.e., the note name appears in the display and an “*” appears in
the “By:” field under the note): When the input pitch is close to a note set
to Bypass, the output remains uncorrected.
Blank (i.e., the note name disappears from the display): A note set to
Blank will be omitted from the scale. For example, setting C

, D
, F
, G
,
A
 to Blank causes a C Major scale to remain. In that case the ATR-1a
would always retune the input to the closest note of the C Major scale.
As an example, the following settings result in a D Major scale with no
pitch corrections applied to F

 and C
:
23: C#D E F#G A B
By:  *     *
Why set Scale notes to “Blank”?
To understand why it is sometimes necessary to set even correct scale notes
to ”Blank,“ let’s look again at the example from Chapter 1.
CORRECTED 
BY ATR-1
ORIGINAL
PERFORMANCE 
						

							26
This phrase is in D Major and, if all the pitch errors were no greater than
about 49 cents, would work fine with a standard D Major scale (D, E, F
, G,
A, B, C
). However, the pitch error of three semitones at the end of the
last note is so large that with B and C
 present in the Scale, as the pitch
fell, the ATR-1a would see first C
 and then B as the target pitch and
therefore allow the error to remain. With C
 and B removed from the Scale,
the ATR-1a continues to see D as the target pitch for the entire duration
of the note and therefore pulls the phrase up to the correct pitch.
Vibrato Page
Prog:XX Dpth Rt  Dly
 yyyyyy xxx zzz dddd
These parameters allow you to superimpose a vibrato (periodic pitch
variation) onto the output sound. The yyyyyy field allows you to select the
shape of the vibrato’s pitch variation through time. The choices are: (off),
SINE, SQUARE and SAW (sawtooth).
The Dpth (Depth) control varies from 0 to 100 cents, controlling the
amount of pitch variation in the vibrato. The vibrato depth can also be
modulated (controlled) by the MIDI MOD WHEEL input.
Note:The Depth setting is used by the MIDI Mod Wheel controller to define
the maximum modulation. You must have the Depth set to a positive
value and the wave type set to SINE, SQUARE or SAW in order for Mod
Wheel control to work.
The Rt (Rate) control varies from .1 to 9.7 Hz and controls the speed of the
vibrato.
The Dly (Delay) control varies from 0 to 3500 milliseconds, and controlls
the time between the beginning of a new note and the full onset of the
vibrato. For example, if Delay is set to 1000, the first 500 milliseconds of a
new note will contain no vibrato and the next 500 milliseconds will make
a transition from no vibrato to the full vibrato.
The vibrato is restarted each time the ATR-1a detects a new attack (i.e.,
input is detected after some finite period of silence). As long as the input
is sustained without interruption, changing pitch will not restart the
vibrato delay. The vibrato is applied after the effects of the SPEED control.
Hence, even with a slow SPEED value of 10, a SQUARE wave vibrato will
still result in instantaneous changes in pitch.

Program Name Page
This page allows you to name each of your Programs. Typically, you would
name the program after the scale that it contains. Alternatively, you could
name it after the song or portion of a song in which it’s used. Do whatever
helps you best remember what you had in mind when you created the
Program.
Program:XX
Name:aaaaaaaaaaaaa
To enter the name, place the cursor under each character space and use
the data knob to select the appropriate character. Names may be a maxi-
mum of 13 characters.
The following characters are available for naming (in this order):
(space) (UPPER CASE LETTERS) (lower case letters) – . / 0 1 2 3 4 5 6 7 8 9 !
“# $ % & ‘ ( ) * + , : ; < = > ? @ [ ¥ ] ^ _ ` { | } ->

To edit a specific Song, you must first select that Song as the current Song.
Do that by calling up the appropriate Song number on the Song Mode
Main Screen. Then, press the PROGRAMS button (the red LED under the
PROGRAMS button will light). The number of the Song being edited will
always appear in the top left corner of the various Song Edit pages.
When editing a Song, you progress from one edit page to the next by
pressing the PAGE button.
When you are finished making changes, press the PROGRAMS button
again. You will be prompted to save the changes (see the Save Song Page,
below).
Song Speed Page
Song:YY      Speed
(0 is fast):  xxx
The Song Speed page operates in exactly the same manner as the Program
Speed page described above. However, the Song Speed overrides the
Speed settings of any Programs called up by any of the Song Steps.
Song Items Page
Song:XX :  1 2 3 4
Programs:  0 0 0 0
Here’s where the action is. The Song Items page allows you to specify a
sequence of Programs along with a variety of options for navigating the
sequence.
To specify the contents of a Song Step, use the cursor buttons to move to
the step number and then use the data knob to select the desired Item for
that Step. Each Song contains 15 Steps. Continuing to press a cursor
button when the cursor has reached the leftmost or rightmost displayed
Step Number will cause additional Step Numbers to cycle across the display.
Each Song Step may contain one of the following Items:
## (A Program Number)While this Song Step is active, the input audio will
be pitch corrected according to the scale associated with this Program. All
other Program parameters (i.e., Speed and Vibrato) will be ignored.
B (Bypass)While this Song Step is active, the ATR-1a is put into Bypass
Mode. 
						

							29
 (Link)When a Song Step containing a Link item becomes active, any
Song Steps in the remainder of the current Song are ignored and the ATR-
1a moves immediately to the next Song (in numerical order). If Song Step
#1 of the new Song contains a “0” (No Program) item, the Song moves
forward to the next non-”0” Step.
Use Link when your Song requires more than 15 Steps.
0 (No Program)Song Steps containing a No Program Item are ignored
when stepping through a Song using either the Foot Switch or MIDI
Increment commands. (i.e., If Song Step #1 contains a Program Number,
Song Step #2 contains a “0” and Song Step #3 contains another Program
Number, pressing the Foot Switch while on Step #1 will move you immedi-
ately to Step #3.)
You can, of course, move to a Song Step containing a “0” Item by using
the the front panel data knob. In that case, no pitch correction will occur
while that Song Step is displayed.
All unprogrammed Song Steps initially default to “0.”
Song Vibrato Page
Song:XX Dpth Rt  Dly
yyyyyy  xxx zzz dddd
The Song Vibrato page operates in exactly the same manner as the Pro-
gram Vibrato page described above. However, the Song Vibrato settings
override the Vibrato settings of any Programs called up by any of the Song
Steps.
