With today's plugins and a myriad of signal splitters, DI boxes and MIDI, everything can be recorded dry (or at least, have a dry signal tapped along with the processed signal) and eventually tone-massaged in the post.
However, some musicians argue that having too many fallbacks can get in the way of the creative process. There can be option overload. There can be a problem with dealing with mediocre sounds during tracking thinking that in can be fixed during post.
If you set up your rig for both approaches, (dry and processed simultaneously), it would take more time to do so. In the case of MIDI that would be very easy, but for drums and guitars, that can be such a pain. For drums you have to select the drum heads and tune them right, and alongside, you might wanna use triggers through a drum module so you can record the sampled sounds and MIDI. For guitar, you would need a Y splitter so one channel goes to a DI box, and the other goes to your rig.
I just wanna know the general trend in recording now. Are you a "tone-massager" or a "no turning back" type of recordist?
