ERD TOAD DIY

Hermaphroditic analogue computer.

Which Venom kills, and saveth such as Venom chance to take.

ERD/TOAD is an hermaphroditic analogue computer driven by the times of pulses and slopes, designed to model both physical and imaginary processes underlying the vocal emissions of various twinned lunar and solar creatures (such as ravens and toads). Ruddy, bursting and overcharged, running by turns hot and cold, breaking and stretching tracts and redefining pulses and control as the venomous spots on the belly of a bulky blackened TOAD, they bring forth all the rarest colours.

By default TOAD re-implements physicist Gabriel B. Mindlin’s ouroboric differential equation which models the mechanisms of birdsong production, computing oscillations within the bird’s syrinx, or sound producing organ. TOAD’s analogue computing elements are normed to follow this model and generate oscillations; only a clock signal (normed to multipliers and all clocks) needs to be supplied to generate audio. This signal can be any changing signal or pulse (it is converted to a clock internally).

This module can be configured to simulate bird calls, or it can function as a state variable filter, or as a chaotic modulation source.

This is a DIY build, fully tested.
