The Keyboard & Polyphony 13 The PDP-400 has "32-note polyphony" which means you can normally play up to 32 notes at once. This number varies, however, according to the functions being used. Keyboard only Keyboard only (dual) Keyboard + rhythm Keyboard (dual) + rhythm Keyboard + ABC Keyboard (dual) + ABC 32 notes. 16 notes. 24 notes (rhythm uses 8). 12 notes 12 notes (rhythm 8; ABC 12). 6 notes q The number of available notes is further reduced if the performance memory or a Disk Orchestra Collection disk is being played at the same time. Further variation occurs with "1-layer" and "2-layer" voices. The polyphony is halved with 2-layer voices: voices 56 (JAZZ ORGAN 2), 58 (COSMIC 1), and 60 (COSMIC 3). The PDP-400 also offers keyboard touch response, so the volume and timbre of notes played can be controlled according to how "hard" you play the keys. The amount of variation available depends on the selected voice. Pitch Wheel PITCH UP 0 DOWN The PITCH wheel can be used to "bend" the pitch of notes up or down while playing. The PITCH wheel is self-centering, and will automatically return to center position - i.e. normal pitch - when released. The PITCH wheel will affect both voices in the Dual and Split modes. Pitch-bend data is also transmitted via the MIDI OUT connector along with the note data. The range of the PITCH wheel is plus or minus one whole tone. Modulation Wheel MODULATION MAX MIN The MODULATION wheel can be used to apply "modulation" in the form of a vibrato effect to notes played on the keyboard. More modulation is applied as the wheel is rolled upward. Unlike the self-centering PITCH wheel, the MODULATION wheel will stay where it is set so you can set any degree of modulation you like and leave it that way. Please note, however, that when you select a different voice the "normal" modulation level for that voice will initially be recalled regardless of the position of the MODULATION wheel. The MODULATION wheel will affect both voices in the Dual and Split modes. Modulation data is also transmitted via the MIDI OUT connector along with the note data.

The PDP-400 has “32-note polyphony” which
means you can normally play up to 32 notes at once.
This number varies, however, according to the func-
tions being used.

The number of available notes is further reduced if the performance memory or a
Disk Orchestra Collection disk is being played at the same time. Further variation
occurs with “1-layer” and “2-layer” voices. The polyphony is halved with 2-layer
voices: voices 56 (JAZZ ORGAN 2), 58 (COSMIC 1), and 60 (COSMIC 3).
The PDP-400 also offers keyboard touch response, so the volume and timbre of
notes played can be controlled according to how “hard” you play the keys. The
amount of variation available depends on the selected voice.
Pitch Wheel
Modulation Wheel
The
MODULATION
wheel can be used to apply “modulation” in the form of a
vibrato effect to notes played on the keyboard. More modulation is applied as the
wheel is rolled upward. Unlike the self-centering
PITCH
wheel, the
MODULATION
wheel will stay where it is set so you can set any degree of modulation you like and
leave it that way. Please note, however, that when you select a different voice the “nor-
mal” modulation level for that voice will initially be recalled regardless of the position
of the
MODULATION
wheel. The
MODULATION
wheel will affect both voices in
the Dual and Split modes. Modulation data is also transmitted via the MIDI OUT con-
nector along with the note data.
The
PITCH
wheel can be used to “bend” the pitch of notes up or down while play-
ing. The PITCH wheel is self-centering, and will automatically return to center posi-
tion — i.e. normal pitch — when released. The
PITCH
wheel will affect both voices
in the Dual and Split modes. Pitch-bend data is also transmitted via the MIDI OUT
connector along with the note data. The range of the
PITCH
wheel is plus or minus
one whole tone.
