Just get a 16 channel Mackie or something similar.
And you got a very simple but versatile set up.
Use first 8 channels for tracking, and the last 8 for monitoring. This way you can have all your recording inputs available and don't have to change anything to monitor.
When you’re all done tracking, you now have a full 16 tracks available to you on mixdown (effects returns, midi, etc.
This is a setup I used for years with great results.
