Working with Martin Howse's TOAD circuit for this as the description of "resonant, clanging and metallic sounds" made me think of bells. By virtue of patching it with other ERD modules to allow chaos a more firm grip on the proceedings, I imagined the resultant sputtering to be in some sort of alignment for the deconstruction of a peel o' bell.
"TOAD can also model a mass-spring-damper system, or series of damped oscillations, which also can be used as a state variable filter.
Here the equation is: x’’=1/m(-(Dx’ + sx) with m as mass, D as damping coefficient and s as springiness. This is a simple equation to begin with, and can produce resonant, clanging and metallic sounds.
x represents the vertical displacement of the spring, x’ is the first derivative of x (which would be speed) and x’’ is the second derivative (which would be acceleration). We patch the equation by feeding the lower derivatives (x’ and x) produced by the first two integrators into the collector. Paying attention to norms, this can be seen in the next diagram. We can use the first multiplier pair as VCA for our input"
Disquiet Junto Project 0682: Unring a Bell
The Assignment: What if you could?
There is just one step to this project. The idea that one cannot “unring a bell” is a fairly common saying, at least in English. But what if you could? What might it sound like? And what use might the unrung bell serve in the making of music. Please record a track in which you try to unring a bell.
