42 Utility Mode 1

U2: Accompaniment Volume Mode
Normally the Auto Accompaniment volume controls are used to adjust the volume of the Rhythm, Chord 1, Chord 2,
and Bass accompaniment parts, as labelled on the PDP-400 panel. This function can be used to assign these volume
controls to other operations.
1: Rhythm, Chord 1, Chord 2, and Bass volume control.
2: Modulation, Pitch Bend +, Pitch Bend -, and Expression. In this mode the RHYTHM slider
controls modulation depth, the CHORD 1 slider controls upward pitch bend, the CHORD 2
slider controls downward pitch bend, and the BASS slider controls expression (overall vol-
ume).
3: Reverb depth for the Rhythm, Chord 1, Chord 2, and Bass tracks. This applies when playing
with ABC and when playing back performance memory data that was recorded with ABC.
When playing back performance memory data that was recorded without ABC, and when
playing back Disk Orchestra Collection data, the CHORD 1, CHORD 2 and BASS controls
correspond to tracks 4-10, 1-2, and 3, respectively.

XPress the Key To Be Tuned Once.........................................................................................................
Press the key to be tuned once to display the current tuning value on the SONG NUMBER
display. “0” indicates normal pitch, positive values indicate that pitch has been increased by
the corresponding number of steps (about 1.2 cents per step), and negative (“-”) values indi-
cate that pitch has been lowered by the corresponding number of steps.
The Individual Key Tuning Feature makes it possible to individually tune each key on the PDP-400 keyboard in
order to match different tuning standards. The pitch of each key can be raised or lowered by a maximum of 50 cents
(approximately) from the standard pitch.
