Applied Acoustics Systems' Strum GS-2 represents a comprehensive overhaul of their guitar synthesis plugin, delivering a genuine production tool rather than a novelty instrument. The plugin addresses a real need: realistic guitar performances from keyboard controllers without the latency, setup complexity, or performance demands of traditional sample libraries.
The core strength lies in its modeling architecture. A completely revised string simulation engine handles pick and finger interactions with bridge coupling, producing articulate acoustic and electric tones that respond naturally to velocity and timing variations. The factory library spans both guitar types with production-ready presets, though the real power emerges when customizing voicings through the redesigned interface.
The strumming engine is sophisticated without requiring deep parameter diving. Automatic chord recognition translates MIDI input into playable voicings, while an integrated MIDI loop library provides rhythmic templates across multiple styles. The new Keyboard Mode and Loop Mode expand flexibility beyond traditional chord-based playing, enabling melodic lines and elaborate rhythm figures.
Signal chain additions matter here. A dedicated compressor, equalizer, and limiter allow realistic amp simulation and mix integration without reaching elsewhere, though the plugin pairs well with external processing. The limiter specifically prevents ear-fatiguing surprises during experimentation.
This upgrade suits producers and composers seeking convincing guitar parts without learning classical technique, particularly in pop, country, and singer-songwriter contexts. Experienced users familiar with Strum Session will find the modeling improvements and expanded controls worthwhile, though the learning curve remains modest. Among keyboard-based guitar tools, it occupies solid middle ground between simplicity and realism.
