Using the Group Control Inputs
The Binloop has contact-closure inputs on the rear panel that can be
used to command groups of Reproducers to Play. When used on their
own, these 8 ‘Play Group’ inputs cause the associated group to play and
loop the associate file. For example, activating the ‘Play Group 2’ input
will cause all reproducers assigned to group 2 to play and loop file #2.
Activating ‘Play Group 4’ will cause all members of group 4 to play and
loop file #4.
