Expert Sleepers Augustus Loop v2.3.0 - Manual (Page 40)

Ignore AudioUnitReset
This setting applies to the Audio Unit version of the plug-in only. Audio Unit plug-ins
usually have the ability to be ‘reset’ by the host application, which usually occurs when
the transport is started or stopped (e.g. Logic resets AUs on transport start, Ableton Live
resets AUs on transport stop), and is intended to clear any delay or reverb tails which
might be undesirable when re-starting playback at a new position. However, sometimes
this is itself undesirable - for example when using the plug-in in a live context, you might
very well want to stop and start playback without wiping whatever loop you had running
in Augustus Loop. Therefore this setting tells the plug-in to ignore the reset messages.
Note that the behaviour of the VST versions of the plug-in is the same as the AU version
when this setting is on, since there is no equivalent reset mechanism for VSTs.
