Cableguys update Curve to v1.3.1

Cableguys have updated Curve to version 1.3.1.

In some cases, Curve 1.3 was crashing host software. This is fixed now, and Cableguys highly recommend that you update to the latest version of Curve.

Also, as a result of user feedback Cableguys have improved the behavior of Curve's new One-Shot-LFO.
