The rattle element sits across the 2 strings and transfers energy from collisions on one end to the other. This has a variable mass on each end, as well as stiffness, gap and edge parameters. The fret is underneath the strings and each one can hit it depending on the amplitude of vibration and the distance between them.

Shape your sound with fully fledged Equalizer, Compressor, Mods, Shaper, and Delay/Reverb effects, five modules that can be re-ordered then programmed deeper in their own tab. Preparation 2’s EQ, Distortion, Drive, Fuzz, Phaser, Tremolo and Wah effects come from Orastron’s Brickworks. There are also 2 LFOs, and keyboard and velocity modulation to customise the response of the model and the FX parameters.

The nonlinear strings can be excited with a customisable pluck, allowing you to choose different impulses for the minimum and maximum Note-On velocity. Or use the scrape of a virtual bow, with bowing force controlled by the Pitch bend wheel and position by the Mod wheel.

Preparation is based on mathematical modelling of 3 basic elements; strings which can be configured as bars, a rattle that joins strings together, and a dynamic fret. Each voice contains a pair of strings which are excited with either a customisable pluck, a bow, or side-chained audio. The acoustic model’s properties are tailored by you, generating a range of sounds from unique instruments to experimental soundscapes. Preparation uses our latest research into collision modelling and fast solver techniques.
