Pro II stands as Wave Alchemy's most comprehensive sampling-synthesis hybrid, drawing direct inspiration from the Sequential Circuits Pro One while transcending its limitations through modern scripted architecture. Built for Kontakt 4 and 5, the instrument combines 6,500+ multisampled waveforms with raw oscillator synthesis, offering producers both immediate sonic gratification and deep sound design capability.
The core strength lies in its dual-layer approach. The preset library delivers 138 expertly sampled patches from an original Pro One, capturing that instrument's characteristic warmth and aggressive filter character. These patches serve as starting points rather than endpoints - they're designed to layer with the synthesizer engine's raw oscillators, enabling true hybrid construction. The oscillator section provides two primary oscillators, two sub-oscillators, and dual noise sources, all derived from Pro One recordings, ensuring sonic coherence across the instrument.
The sequencer deserves particular mention. Tempo-syncable and step-based, it moves beyond simple step sequencing by offering per-step filter modulation alongside shuffle randomization, capable of generating everything from subtle stepped filtering to complex, evolving sequences that justify the "analogue style" description.
Pro II occupies a specific niche within the sampling-synthesis landscape. It's particularly valuable for producers seeking authentic vintage monophonic character without hardware constraints, especially those working in bass-heavy genres where the Pro One's legendary status carries sonic weight. The extensive scripting and intuitive GUI lower the barrier for sound design compared to raw Kontakt programming, though serious synthesis work demands engagement with multiple editing pages. For engineers valuing authentic sampling-based synthesis over purely algorithmic generation, Pro II delivers focused, expertly crafted sound sources.
