  • A Slew limiter is a device that "smoothes" an incoming signal, limiting the maximum rate of change of the output voltage over time.
  • It is widely used with pitch CVs to obtain portamento but is also very useful to convert a gate signal into a basic envelope.
  • The module has independent time controls for rising and falling voltages, each with it’s own CV.
  • The “SHAPE” control allows you to change the curve response from linear to logarithmic.
