That'll be essential when dialling in settings on the dual band. A different range on each band but operated from a single knob. Otherwise, one is just adjusting the same setting range on 2 identical compressors.
It's was more featured than the compressor found in the Ultrawave. The line that made me laugh in the Source Audio Youtube vids is the bit where Bob said "we were trying to put the Ultrawave compressor in a box, do it in Stereo...and then...yeah we just couldn't stop there...."
Having a list of accurate Compressor models to choose from really makes this an incredibly versatile compressor. One of the things I loved about the EBS MultiComp was the three way character switch. I could flick between a Multband, standards and tube compressor at a flick of a switch. It was only limited by it's models and the single compression knob. Where as the Atlas has lots of models, Stereo and multiband options...plus (effectively) 8 surface knobs. Plus the 8 band Graphic EQ and wide 3 band controls. This is a seriously versatile compressor. Plus all of the expression, mappable controls and Midi...it's making me very interested. I really think that Source Audio are going to sell a lot of these units. Another very strong product from Source Audio!
