Getting Connected
Tetra has several inputs and outputs on its back panel.
Power Input — Connect the power supply included with your Tetra. The power
supply comes with different AC adaptor prongs that allow it to work anywhere
in the world. If for whatever reason you need to use a different supply, it must
match the specifications printed on the front panel.
Note: The power supply label says “Evolver” on it; we use the same
supply for the mono Evolvers, Mophos, and the Prophets.
USB — Tetra transmits and receives MIDI data via this standard, Type B, USB
receptacle.
MIDI In — To receive MIDI data from another device, connect this to the other
device's MIDI Out.
MIDI Out — To send MIDI data to another device, connect this to the other
device's MIDI In. This output can also be configured as a MIDI Thru using the
MIDI Out Select parameter in the Global menu.
Poly Chain Out — Up to four Tetras can be chained for increased polyphony
and multiple Tetras can be poly chained with a Prophet ’08 or Mopho Keyboard.
For details, see Using Poly Chain on page 36.
Note: When Poly Chain is turned off in the Global menu, the Poly Chain
Out simply mirrors the MIDI Out and transmits the same data.
Audio Outputs — Tetra has four, unbalanced, ¼ inch outputs. 1/Left and
2/Right are the summed outputs of all four voices in Stereo or Mono mode and
are typically used for “normal” polyphonic or unison playing. They are also the
direct outputs of voices 1 and 2 in Quad mode. Outputs 3 and 4 are the direct
outputs of voices 3 and 4, respectively, and are always mono. The individual,
direct outputs are typically used in Multi Mode or Combo Mode, so that each
voice can be mixed and processed separately. For more about the Audio Out and
Multi Mode parameters, see Global Parameters on page 13.
Phones — A ¼ inch stereo headphone jack.
