What we say about the Oberheim TEO-5 Desktop Module...

All the fantastic sound and heritage of the TEO-5 polysynth, now in desktop format!

Manufacturer's description

NEW: OS update November 2025 includes:

• Poly Chain, which lets players link two TEO-5s for a fully integrated 10-voice instrument
• 10 new arpeggiator patterns, including creative modes like Spiral and Leapfrog
• Whiplash arp timing mode, which dynamically adjusts note values based on how many keys are held
• Violet noise, for expanded sound design possibilities

The TEO-5 desktop module is a compact powerhouse for musicians and producers seeking the iconic Oberheim sound in a space-saving format. This new addition to the Oberheim synthesizer family delivers all the same signature sounds and synthesis features as the acclaimed TEO-5 keyboard.

Featuring genuine analog oscillators and the legendary SEM™ multimode filter, the TEO-5 desktop module enables users to recreate the classic Oberheim sounds that have defined music for decades. With extensive modulations, including linear and through-zero FM, and modern effects, TEO-5 opens up new sonic possibilities.

Designed for intuitive use, the TEO-5 desktop module retains the knob-based experience of its keyboard counterpart. All synthesis features are easily accessible from the top panel, allowing for real-time adjustments and fine-tuning of sounds. This hands-on approach ensures musicians can quickly achieve the perfect Oberheim tone.

Ideal for those with limited studio space, the TEO-5 desktop module offers all the exceptional presets and sonic control of the keyboard version in a footprint less than half the size. Its compact design integrates seamlessly into any creative workflow, making it a versatile addition to any setup.
