Phoscyon 2 is a sophisticated instrument plug-in that delivers an authentic emulation of the iconic 303 bass synthesizer, enriched with enhancements beyond the original hardware. Its completely redesigned sound engine captures the classic 303 tone with exceptional accuracy while offering additional synthesis parameters inspired by popular 303 modifications and circuit bents. Users gain access to a deep range of controls, including service trim pots originally meant for calibration, as well as unique hidden parameters not found on the original unit. A standout feature is the innovative vibrato effect, which replicates a rare technique used by 303 artists, creating a distinctive sound through a two-note tremolo smoothed by note sliding, controllable via intuitive knobs.

The plug-in features an integrated sequencer and advanced arpeggiator, allowing for flexible pattern creation and playback with tight synchronization to digital audio workstations. Patterns can be triggered through multiple methods such as MIDI notes, MIDI CC, or directly via the interface, with drag-and-drop export capabilities for seamless workflow integration. Creative expression is further enhanced by real-time non-destructive control over accents, slides, and vibrato, as well as a built-in randomizer to effortlessly generate and fine-tune sequences. Phoscyon 2 offers two distinct pattern editor views—a modern piano-roll and a classic keyboard layout—catering to different user preferences while maintaining the character of the original 303 sequencing experience.

Complementing the authentic sound engine is a comprehensive effects chain that includes distortion with 19 selectable models, compression, a five-slot insert effects rack, algorithmic reverb with detailed control over reflections, parametric EQ, tempo-synced delay with filtering, chorus, and a limiter with soft clipping. The plug-in supports various play modes, including monophonic synth operation with expression controls and pattern-based sequencing for dynamic performances. With over 800 presets and patterns, scalable high-resolution graphics, MIDI learn functionality, and a user-friendly interface, Phoscyon 2 offers an immersive and powerful tool for producers seeking the classic 303 sound with modern enhancements.
