The Upright

The Upright

Session Keys has been created with the philosophy that the best piano is the one that suits the music you are making. Sometimes you need a grand piano and at other times an upright fits better.

Session Keys Upright works well in pop, rock but is equally at home in hip-hop and scoring, cutting through the mix with clear tones and stacks of personality.


Dual Sound Universe

Dual Sound Universe

Select from two distinctive sample sets, each with its own look, feel and sound identity.
"Open" is characterized by spatial stereo sound with individual notes meticulously detuned, creating a chorus-like effect when combined.
"Closed" is for musicians demanding a modern, intimate and perfectly tuned piano for their tracks – direct, focused and edgy.




This stylish pentagonal controller makes Session Keys Upright more than just a great piano. Not only is it beautifully designed, but it's a phenomenally powerful tool, able to transform the whole sound from normal piano to eerie atmospheres to pure mechanical sounds and back.
Instant flexible control in a single knob.




The sound of ideas coming to life: the Animator offers an intuitive and inspiring way to jam with more than 400 flexible piano phrases that follow your harmonies. Use the pitch bend and modulation wheels to increase or decrease complexity and control the dynamic of your session partner.
