Tone.TickSignal

↳ EXTENDS Tone.Signal

Tone.TickSignal extends Tone.Signal, but adds the capability to calculate the number of elapsed ticks. exponential and target curves are approximated with multiple linear ramps. Thank you Bruno Dias, H. Sofia Pinto, and David M. Matos, for your WAC paper describing integrating timing functions for tempo calculations.
