How well does Reaper deal with outboard gear? In terms of mix use, does it's delay compensation provide phase accuracy to the originals?
I've never used outboard with Reaper but yeah there is a ReaInsert plugin that you just insert in your chain and within the plugin itself you can patch in the hardware, then you can move the plugin wherever you want and the hardware setup is maintained within it. I've never used it but apparently people have mixed results when using a LOT of instances. Most people seem to have no trouble using only a few instances of it though, but again I haven't used it. Best is to try it yourself and see how it works for you.
