Random rate controls how often the playhead will jump to a new random point.
Playback speed does what it says on the tin: controls the speed of playback of the clip. This is the part that still needs work, because ideally this should take its cue straight from VDMX.

Now also with automatic or manual trigger options:

auto_trigger_switch turns automatic triggering on or off
random_trigger gives a new random value when auto_trigger is off

goto10_RandomPlayback.qtz

This patch now uses some private beta VDMX options and I don’t feel comfortable sharing that on the world wide web yet. Please contact me directly if you want to beta test.
