Inspiration

PX Apollo is based on a rare synthesizer prototype from the early ‘70s of which only 2 are known to exist. Part of a larger project that was eventually abandoned, this instrument was the precursor to one of the world’s first and most prolific polyphonic analog synthesizers. With a sound that can be described as rich, warm and surreal, this instrument was extraordinarily playable for the time, sporting velocity sensitivity and a performance interface, while its polyphonic 71-voice architecture signaled the coming paradigm shift in synthesizer design that would soar during the following decade.

Instrument

The UI for PX Apollo was inspired by the aesthetics of the original hardware, while the layout and control schema were designed to provide intuitive and efficient use while maximizing flexibility, allowing for both quick edits to preset sounds and deep customization by way of a full compliment of synthesis tools and effects including 3 oscillators, envelope generators, high-quality filters, pitch and stereo controls and per-oscillator modulation and arpeggiation.
The PX Apollo project represents an enormous effort and commitment to quality on many levels. Due to the components available at the time of their design, early polyphonic synthesizers were and remain particularly susceptible to failure and require continued maintenance. The unit used for PX Apollo was no exception, initially inoperable it required a tremendous restoration effort and no expense was spared to ensure complete authenticity and original functionality.
With the restoration complete we set about to document this historic instrument as accurately as possible. We created a huge master sample catalogue with the best hardware available. Each key was sampled in a multitude of configurations and for each 4 round-robins were created per note. The resulting PX Apollo sound bank consists of over 4,000 samples. From this library over 150 patches were made by our sound design team, delivering a fantastic collection of ready-to-play patches.

PX Apollo is one of those really rare synths that is beautiful modelled here! The bass sounds sounds so good and fat with beautiful harmonics in them. The moment I heard it went straight into my template!

I often feel the original hardware is no longer needed or wanted, they're THAT good. Kudos to you all... Keep 'em coming.

As a collector I always dreamed of having the machine, but every one out there is in bad shape or damaged. It's very hard to find a good one! My hunt is over with the PX Apollo! It sounds just perfect.

This one will become your polyphonic analog go to synth. Incredibly friendly interface, all the classic waveforms and more oscillators than you think. UVI achieved another amazing instrument that gives you a magnificent warm and creamy sound that will blow your mind.

"PX Apollo sounds gorgeous - warm, lively and very 'analog'."
"The 14 Master Voice presets perfectly capture the sound of the original instrument and UVI’s factory presets all begin with the original sounds but take advantage of the host’s architecture to make them more exciting."
"PX Apollo sounds great and produces a hott of warm vintage sounds or more modern sounds at the drop of a hat. It’s easy to work with, but fully customizable."
