Karp is a plucked string synthesizer that utilizes the classic Karplus-Strong algorithm to produce realistic and expressive string sounds. Designed to integrate seamlessly with modern digital audio workstations, it supports MIDI Polyphonic Expression (MPE) for detailed per-note pitch bending, enhancing performance dynamics when enabled. This feature allows musicians to add nuanced pitch variations that bring the instrument to life.

Optimized for live performance and efficient operation, Karp runs its graphics smoothly on the GPU, which reduces CPU load and ensures stable audio processing. This design approach helps maintain low latency and high responsiveness during complex sessions, making it suitable for both studio production and stage use. The interface provides intuitive controls such as Decay, which adjusts the length of the note’s fade-out, and Damping, which shapes the tonal character by filtering the feedback loop and controlling the noisiness of the exciter.

Karp’s user-friendly implementation of MPE requires activation within both the plugin and the host DAW, allowing musicians to fully exploit its expressive potential. By enabling MPE, users gain access to per-note pitch bend and other expressive controls that elevate the realism and musicality of string synth sounds. This combination of classic synthesis and modern performance technology makes Karp a powerful tool for artists seeking detailed control over plucked string textures.
