Beta testing Kaivo has been a blast and if you’re familiar with Madrona Labs’ Aalto, you should be familiar with the architecture of Kaivo, however the sounds are nothing alike. Physical modeling and granular made fun. Surachai presets are coming with the next update.
Kaivo, a new software synthesizer from Madrona Labs, is now available for Mac OS and Windows. Kaivo combines two powerful synthesis techniques, granular synthesis and physical modeling, with a patchable interface designed for ease of use.
Physical modeling is a way of making sounds using equations that model vibrating objects in real time. Like a picture is sometimes worth 1000 words, a physical model is worth 1000 samples. Every time a model is triggered, it makes a slightly different sound due to the initial conditions when the sound starts. This subtle variety can quickly give a very lifelike quality to sounds that would be tedious to recreate with sampling. Kaivo’s models include metal, nylon and gut strings, different sizes of chimes and springs, wooden instrument bodies, membranes and metal plates.
Kaivo brings some of the latest academic research in physical modeling to a patchable package for the first time. Mathematically speaking, its finite difference time domain (FDTD) models let the player reach inside the instrument and affect the internal vibrations at any point. This allows for a fine degree of realistic detail, like the bridge rattles on a “gut string” model, for example. And while Kaivo is capable of making very realistic sounds, it is also designed to apply this subtlety to abstract creations.
Expansive spatial sounds are possible in Kaivo, with independent panning available on grains, resonators, and body. Kaivo’s granulator feeds all of its models from a 2D map of sound with up to four channels. The body is a true 2D vibrating model of a physical object, with left and right pickups that create a spatialized mix of all the frequencies flowing through it.
Users of Madrona Labs’ Aalto synthesizer will find Kaivo’s design very familiar, with its fully resizable, vector-based user interface. Every control is on a single page. The patcher in the middle makes it possible to create complex patches quickly and easily, with connections that can never obscure other controls.
“Kaivo” is Finnish for “well,” as in, a deep well of sounds. Kaivo combines the natural qualities of vibrating objects with a huge potential for experimentation.
Kaivo is available in AU and VST formats for Mac OS and in VST format for Windows. Both Mac and Windows versions are fully 32- and 64-bit compatible. System requirements: Mac versions require OS 10.6.8 or higher. Windows versions require Windows 7 or 8. All versions require a 1.6GHz Intel Core Duo processor or higher.
Kaivo is available to purchase at the Madrona Labs website for $129. Free demo versions are available for download. For more information about Madrona Labs and to purchase software, visit the website at http://madronalabs.com.
