Sigma Delta supports:
Pro Tools (AAX and RTAS plug-ins)
For Pro Tools, Cubase, Nuendo and Ableton Live
A very powerful feature of Delta Control is that the plug-in stores its volume data in the track using the same dB law as the DAW fader volume data.
This means that the automation cut/paste edit commands in the DAW allow you to copy DAW fader automation into the δelta Control plug-in volume track, to play out on the Sigma channels with an accuracy better than 0.2 dB.
Other VST, VST3 and AAX-compatible DAWs still allow Sigma Delta to be automated from within the DAW, but cutting and pasting automation from the DAW fader to the Delta Control plug-in fader will not be accurately translated.
