Single Fader Plug-in

δelta-Control (δ-Ctrl) Single Fader Plug-in is a native AAX/RTAS/VST/VST3 plug-in that allows automation of Sigma channel volume as if it were a DAW plug-in. Inserting 16 instances into the DAW session will allow control of volumes and cuts for all 16 of Sigma’s channels. The automation system in the DAW is used to record and playback Sigma volume control data entered either directly from the fader in the plug-in GUI or from a SSL MCU control surface which is controlling Sigma directly. The δ-Ctrl plug-in is inserted into a DAW mixer audio or aux channel. The plug-in then receives and sends volume data from Sigma Delta via a high speed ethernet network connection. Audio on the DAW track passes through the plug-in slot unprocessed so the plug-in can be combined with other DAW plug-ins. Sigma’s Volume and Mute switch are represented as plug-in parameters in the δ-Ctrl plug-in GUI and their automation data is recorded to the automation lane of the selected DAW channel. In playback, the plug-in converts the stored automation data from the DAW into δ-Ctrl messages and routes these back to Sigma via the SSL Logictivity network connection.

16 Fader Plug-In

The 16-fader ‘Sigma Delta 16’ plug-in provides compatibility to Logic users, as well as offering an alternative workflow to ‘Sigma Delta Single Fader’ plug-in users. The plug-in is available all formats including AAX/AU/VST3/VST. The Sigma Delta 16 plug-in allows users to write automation for Sigma’s 16 analogue faders from one plug-in window, solving Logic’s inherent limitation of only being able to write data to one plug-in at a time. In addition to this, Sigma Delta 16 can control pans, Solo, Cut, mono/stereo selection and mix bus assignments.

Monitoring Plug-In

The Sigma Delta Monitoring plug-in allows full control of Sigma’s monitoring section, including monitor and headphone levels, monitor cut, dim and source selection. It allows Sigma's Monitoring section to be controlled from your DAW, a control surface or the SSL Remote Application running on a computer or a tablet device.









 

Instant Recall

The full effect of these plug-ins delivers an analogue summing mixer that instantly recalls when moving between DAW sessions. Sigma Single Fader plug-in users can continue to enjoy their established workflow and single fader-based sessions are backwards compatible, providing that the Delta Single Fader is updated to version 2.1 after Sigma is updated to 2.1 software.

Controlling Sigma Delta

Sigma Delta offers tight integration into multiple studio workflows and setups. The Sigma Delta plug-ins provide streamlined implementation with Eucon enabled control surfaces such as Avid® S3, S6 and Artist series or the Pro Tools Control app. The plug-in parameters map across Eucon control surfaces via the Insert editor, meaning that users can easily move between controlling their summed Sigma mix and their DAW session from the same surface. Likewise, Nucleus users continue to be able to control Sigma directly via the Nucleus’ ‘Sigma Delta’ MCU profile, whilst being able to switch layers to control their DAW session.
