StringLab is a physical string modeling synthesizer based on Karplus-Strong theory. It is capable of reproducing the sounds of many different types of instruments, but is especially useful in the reproduction of hammered or plucked strings and other types of percussive instruments. It works by passing carefully crafted waveforms and short bursts of white noise through a series of tuned delay lines. The delay lines have an internal feedback loop with a series of filters to mimic the natural decay of harmonics found in a real instrument. StringLab allows you to discover the character of real-world accoustics, exploring the physics of how materials interact. Many new and original textures are born out of experimenting with the settings, so don't be afraid to experiment and create your own unique and dynamic instruments. Features •Karplus Strong based physical modeling. •Exciter Impact with multiple modes. •Exciter Noise with many envelope driven filters. •2 resonator objects with feedback. •8 bands per object with inversion. •4 Coupling modes. •Supports Frequency Dispersion. •Feedback low/high Damping. •Per object Body Filter. •Pitch Deformity. •External live input mode. •Preset randomiser. •Build it Preset Manager & Favourites. •Search Presets. •Drag & Drop preset export of presets. •Supports Color Sets.
