The rack mixers do not have DAW Mode, which integrates hardware and software (Studio One) to quite some extent. What you can do is to use Studio One as "insert" to the 32R's channels, like adding a plug-in or plug-in chain to a channel. You can also replace the rack mixers effects by using effect plug-ins of or in Studio One. Another possibility would be to create effects in Studio One and send the effect bus to the rack mixer via "Tape In" (Digital Return). You can use automation on recorded tracks only, not as adjustments of live signals. DAW Mode in a Series III console would also not allow this, but the "worlds" would be closer together.
You probably have to look for another solution or work with (stereo) tracks.
