Lydian Audio
If its one thing I dislike about the digital world is it seems to be very wishy washy. There is no clear cut "this is how you do it" scenario.
Nah... you can actually do more, so people feel the "need" to do more (just because they can sometimes).
Simplicity is elegant... and many "best known" songs have that element.
The digital age introduced a few wonderful things... For audio, if you get the cleanest signal, you can save this and always come back to it years later... decide the processing "doesn't fit," alter it to a completely new sound "instantaneously," and off you go. For MIDI, the data is simply key information, so can "plug and play" to different synths and tailor the audio output in the same way. Digital allows you to always go back and "change your mind" and those changes do not require re-recording (or figuring how to make the tape not squeal because it has been shelved for years).
AT said it most succinctly... resist (violently at times) the urge to pile effects onto
anything... if you feel that need, the base signal might simply need to be redone.
