Specifications

26
For Stack, both layers respond to MIDI notes for the entire key range, enabling
two patches to be played simultaneously with a single key stroke. Voices 1 and
2 are assigned to layer A, 3 and 4 are assigned to layer B.
Split assigns layer A from the lowest note to below the split point (see previous
parameter) and layer B from the split point to the highest note.
Note: In Combo Mode and Multi Mode, layer B is ignored.
Clock Parameters
The sequencer and arpeggiator share the BPM and CLOCK DIVIDE settings.
BPM: 30…250 — Sets the programmed tempo for the sequencer in BPM (beats
per minute).
Clock Divide: see table — Sets the note value for each sequence step relative to
the BPM.

Arpeggiator Parameters
Tetra’s arpeggiator has four different operating modes and can be synced to a
MIDI clock source.
Note: If the arpeggiator does not seem to be working, check the G
LOBAL
parameters to make sure Clock is set to Internal. If Clock is set to use an
external clock source, Tetra must be receiving MIDI clock messages in
order for the arpeggiator to run.
The tempo and note value are determined by the Clock Parameters.
