PX WaveFrame is a rather distinctive synth that is unlikely to become your "do-it-all synth," but it offers atypical, original, and dated sounds, making it a good complement to more universal plugins or modules. It's very appealing and, as is often the case with UVI, it comes with good presets that are very usable as they are or can serve as a foundation for easily creating more personalized sounds.
In any case, it is an interesting addition to the Falcon ecosystem, which I particularly appreciate. I discovered UVI's platform when the production of "The Journey" was already well underway, but it quickly became absolutely essential for me. It is even the "foundation" for most of the tracks in "Lostblood," chapter 2 of the musical adventures.
