It provides considerably more than on/off switching. The FreqInOut plugin controls hardware routing, unit and device selection, send and return levels, phase, delay trim, bypass, Hardware Mix for wet/dry processing, M/S processing, and analog-matrix routing. These plugin settings are saved with your DAW session.
However, the FO1’s physical controls are not assignable plugin controllers, and the plugin cannot move or automate the knobs and switches on connected analog equipment. The plugin’s photo-capture feature lets you save a visual reference of your outboard hardware settings with the session for easier manual recall.
FreqInOut FO1 has four balanced line-level inputs. You can record line-level sources such as synthesizers, outboard equipment, or signals coming from an external microphone preamp.
FO1 does not include microphone preamps, Hi-Z instrument inputs, or 48 V phantom power. Microphones therefore require an external microphone preamp, while guitars and similar instruments normally require a suitable DI box or instrument preamp.
The plugin provides gain controls for level matching, but these do not replace a microphone or instrument preamp.
