δ-Ctrl is a native AAX/RTAS/VST/VST3/AU plugin that allows the user to automate Sigma channel Volume and Mute data,
as though they were standard DAW Plugin parameters. The δ-Ctrl plugin is inserted into a DAW mixer channel, which then
receives and sends control data for the assigned Sigma channel via a high speed Network connection. Any associated
audio on the track is unaffected and passes through the plugin slot unprocessed.
The channel volume and mutes are represented as plugin parameters and will have automation data saved in the
associated plugin track automation playlist. This data together with any associated automation record enable commands
generated from an MCU surface connected to Sigma are streamed via the same network connection that carries ipMidi
and the Remote app messages using proprietary SSL Logictivity Network protocols. The plugin decodes the messages
In Automation Playback the plugin converts the stored automation data, from the DAW automation playlists, into δ-Ctrl
and converts them to conventional plugin parameter values, which can be saved as automation streams in the DAW track.
messages and routes these back to Sigma via the Logictivity Network connection.
These automation playlists can be viewed and edited as normal plugin data in the DAW tracks and will be saved alongside
the rest of the session data. The plugin's data values are expressed in dB units for faders or as text for the mutes, which
relate directly to the parameter being controlled when automation moves are viewed in the track automation lanes for
editing. Sigma Volume data is saved using the same dB law as Pro Tools Fader automation so that the 'Paste Special'
command can be used to copy existing Pro Tools fader data into the plugin. This feature is DAW specific and may not
necessarily be available with other systems.
