Cableguys has updated the Curve software synthesizer to version 2.0.4, and the VolumeShaper effect plug-in was updated to version 3.1.2.
These updates fix a crash bug in Curve and VolumeShaper for old versions of OS X and a bug for Curve which could result in wrong sounds when switching presets while holding modwheel or aftertouch.
