You can set up send/return device mappings yourself, but it’s a pain and easily prone to error (speaking from experience..!). BUT open the project wizard, and scroll down for ‘Create new mixer bus mappings’ in the Audio Mixer Mappings section.
This will create a ‘Bus (x) Send’ and a ‘Bux (x) Return’ mapping in your devices folder (or wherever yours end up). I generally rename them straight away according to function (‘Reverb Send’/’Reverb Rtn’, etc).
Now in the arrange window create a new track, and assign it the ‘Reverb Rtn’ mapping. Then create a group track around it and map a reverb to that group. You now have a return bus.
In a track that requires some ‘verb, create a group track around it, and assign ‘Reverb Send’ to it. This will route as much of the audio as you want (a ‘Send’ dial appears on the track) down to the ‘Reverb Rtn’ mapping.
Repeat the last paragraph for every track that requires the ‘verb.
On a piece I am doing at the moment, I have 4 bus mappings. One track uses all 4 busses, so has quite a heirarchy of sends! The way that Frits has done it allows you to route to the send at any point, which is quite powerful – you could send some of the raw audio to a verb, then add some chorus, and send to a delay, and finally add a touch of overdrive, so the resulting sound is 3 different layers thick – all from one track. Most over DAWs would have to use 3 tracks to accomplish this!
