Oberheim Announces TEO-5 OS Update

Oberheim has announced a free OS update for its TEO-5 synthesizer, which they say adds powerful new features that make the instrument even more versatile and inspiring. The update is now available for download from Oberheim's website.

Tom Oberheim told us, "TEO-5 was designed to bring the classic Oberheim sound to more players. This update pushes that vision further -- adding features that make it even more useful and inspiring."

Here's more details direct from the company...

The highlight of the update is Poly Chain, enabling two TEO-5 units to be linked for a fully
synchronized 10-voice Oberheim experience. This allows for complex chords and lush
textures without compromise, and all panel controls are mirrored across both units for
consistent sound and performance.

Additionally, the arpeggiator now includes 10 new play modes that go far beyond
traditional patterns. Modes like Spiral and Leapfrog introduce new rhythm and melody,
creating parts that twist, turn, and evolve in ways that spark creativity.
Also new is Whiplash, a timing mode that keeps each arpeggiator cycle the same length
no matter how many keys you hold. This means the note values shift dynamically,
producing rhythmic tension and release that stays in-step with the overall bar-length of
your composition.

To round out the update, violet noise joins the sonic palette. With its emphasis on high
frequencies and reduced low-end content, violet noise is ideal for creating smooth
shimmering textures, airy effects, and unique percussive elements.

TEO-5 combines authentic Oberheim tone with modern creative tools. With true analog
oscillators, the legendary SEM filter, linear through-zero FM, and a deep modulation
matrix, TEO-5 offers a vast sonic palette in a compact, performance-ready design. Take the
next step with TEO-5 and download the Poly Chain OS Update today.
