ARP / SEQ
This module contains two very important features: the Arpeggiator and the
Sequencer. In addition to the controls found here, the PLAY, HOLD, and TAP buttons
located on the Left-Hand Controller are active in operating the Arpeggiator and
the Sequencer. This module also contains patch points for KB OUT (Keyboard Pitch
Control Voltage), GATE OUT, and KB VEL OUT (Keyboard Velocity Control Voltage).
ARPEGGIATOR
The Arpeggiator takes the notes being held on the keyboard, and plays them one at
a time in a repeating, rhythmic pattern. This is useful for creating swooping cascades
of notes, building a rhythmic base, or for generating new and fun musical ideas.
Grandmother allows you to select the order in which the notes are played, and also
provides the option of repeating the pattern in different octaves.
SEQUENCER
The Sequencer is a step sequencer that can store up to 256 steps per sequence.
Each step can be entered as a Note or a Rest, and individual steps can also be
entered with a Tie and/or an Accent. Three separate sequences can be stored and
called up during performance.
NOTE: Sequence memory is retained even with the power off, so sequences can be programmed in
advance and used later in performance.
RATE
The RATE knob sets the playback speed of the Arpeggiator and the Sequencer,
with a tempo range of 20 – 280 BPM (Beats Per Minute). The accompanying
LED ashes at the current Rate setting. If Grandmother is synced to MIDI,
External Clock, or Tap Tempo, then the RATE knob selects timing values that
are musical subdivisions of this external tempo.
TIP: The Rate can also be set by pressing the TAP button, at the desired tempo,
at least three times in a row. To exit Tap Tempo, press and hold the TAP button
for about one second, until its light turns off.
NOTE: When synced, turning the RATE knob selects even and dotted note values; pressing the SHIFT
button while turning the RATE knob selects triplet note values.
MODE
The MODE switch allows you to select between the Arpeggiator and the
Sequencer. A third position places the Sequencer into Record mode.
ARP
With the MODE switch in the ARP position, pressing the PLAY button will
activate the Arpeggiator.
SEQ
With the MODE switch in the SEQ position, pressing the PLAY button will activate the Sequencer.
REC
With the MODE switch in the REC position, the Sequencer is armed for recording. From here, entering
a new note will overwrite any existing sequencer data for the currently selected sequence (1, 2, or 3).
If the MODE switch is set to REC while the sequencer is currently playing back an active sequence,
individual notes in that sequence can be updated in real time.
