Tinker is a free Rack Extension for entering mathematical formulas to manipulate CV signals. A formula can contain numbers, variables, constants, operators, functions, and parentheses. The result of evaluating a formula is clearly displayed, and an integrated help menu lists all available functionality for quick reference. Tinker also supports patch loading and a configurable patch description.
You could use Tinker to perform arithmetic between different CV inputs, generate a tempo-synced waveform, build branched routings using the built-in knob and switch, and more. Explore endless possibilities!
