Steinberg’s HALion product planners may look all these cool videos of the upcoming Vengeance Phalanx sampler:
Looping features, loop can be modulated!, special scratch mode: Vengeance Producer Suite - Phalanx Tutorial Video: 05 Loop Page - YouTube
Browsing with instant preview: Vengeance Producer Suite - Phalanx Tutorial Video: 01 Library - YouTube
These features were all requested for the next major HALion update at the start of this thread.
There are more vids, worth to check for great ideas and implementation.
