Description This command sets the automatic selection of the millimeter source
module interface connector. The synthesizer looks at both front and
rear connectors and determines the type of source module
(if any) connected. If a source module is present at both connectors,
the synthesizer selects the front connector as the active one. After
selecting the interface the instrument frequency limits and multiplier
are altered accordingly. However, the leveling point is not changed.
See Leveling Point Module to set the synthesizer to level at the
output of the source module.
An asterisk next to the key label indicates this feature is active. This
feature is the default after preset.
