MasterRig is great, but could be much better if we have option to add 3rd party VST effects into the rig chain. For example Equalizer A -> UAD Oxide Tape Recorder -> UAD Elysia Alpha Compressor -> Stereo Imager -> Limiter.
Now we have to load up MasterRig with Equalizer A, then Oxide Tape and Alpha compressor as another insert effects, then MasterRig with Stereo Imager and Limiter.
Another and very useful feature would be something like safe clip for compression file like MP3. Sonnox Codec Toolbox has this feature which prevent audio in mp3 or aac from clipping. As Im using multi format export, where i have 16bit wav, mp3 192kbit, 320kbit, aac and aac+ for iTunes, there is no way how to control the compressed output level. So if i want to prevent 320kbit mp3 and aac+ from clipping, I have to pull the master fader approx about 0,8dB down, but 192kbit has still numerous clips in the exported file, so i would have to do separated export with lower loudness level for this particular format. Then i have to open the exported wav file and gain the exact volume level ive lowered by the master fader. If we would have the “safe clip” option which will prevent mp3 and aac from clipping it will make our life much easier and we could fully use multi format output.
