Sinh is a control-domain math block that outputs the hyperbolic sine of its control input. It works purely on control signals, mapping a single control input to a single control output, and has no adjustable parameters.
On every tick it evaluates the hyperbolic sine of the current control value and writes the result to its control output. It runs once per engine tick, one sample-frame at a time, in keeping with WaveWarp's sample-per-sample engine.
