The architecture applies a friction
algorithm to a 2nd order mass-spring, modeling the
reactivity of surfaces in contact. Two waveguides
are used to model the primary resonances of a
physical object. The synthesis engine employs 4x
oversampling, providing reasonable emulations of
sounds produced by friction, such as squealing
tires, squeaky hinges and wiping noises.
Modulation consists of three
32-stage envelopes (designed by Chris Kerry,) 4
configurable LFOs and an x-y pad. A group of sends
allows modulators and controllers to be assigned to
multiple destinations, similar to those used on
xoxos' other physical models such as Fauna
and Oscine Tract.
generates MIDI sequences using an algorithm modeled
on biological behaviour. The measure is treated as a
'year' and note events are determined by parameters
describing the 'life cycle' of each note.
The sequences are usually patterned,
yet rarely repeat exactly, creating motif-like
