UVI U1250 | Instrument
The first keyboard to deliver sampled waveforms via oscillator, the K250, was a joint effort carried out with legendary musician Stevie Wonder, the founder of ARP - Alan Pearlman, and prolific synthesizer artisan Bob Moog, among others.
Able to produce brilliant acoustic sounds without the use of disk drives, the K250 was the world's first ROMpler. Boasting an impressive 24 voices of polyphony and a beastly 88-note weighted keyboard, the K250 was designed with performance in mind. Following in its success the K1000 was released with a sportier 76-note keybed. It offered extra portability and sounds at the expense of a simplified front panel.


In making U1250 we decided to tackle both the K250 and the K1000, programming a wide range of sounds including acoustic and electric pianos, bells, mallets, drums, percussion, guitar, bass, pads, wind, brass and other orchestral instruments. The sounds in U1250 evoke a nostalgic vintage vibe thanks to the character of early digital sampling implemented in these instruments. The hardware was tediously multi-sampled to create an authentic playing experience and dynamic sound that feels and acts like the real thing.
All the sounds in U1250 can be serve as immediate inspiration, or starting-points for your own sound design. Built-in amplitude ADSR, multimode filter with ADSR, stereo unison, legato, noise oscillator, quick modwheel mapping, modulators, and high-quality effects from UVI allow you to quickly adapt a sound to your needs to radically warp it into something completely new.
Two studio icons of the late ‘80s and early ‘90s impart a special sound and history, and through U1250 a new life as a modern instrument with an uncompromising vintage-digital flavor.
