It's been several years since I last found much time to indulge my music hobby but I'm starting to think about it a lot lately so I want to get back up to speed a bit, at least conceptually.
When I was last active, MIDI was already well established and it did a lot of wonderful things but programs like Cubase 1.0, which is what I used, had no ability to handle analog sources like voices or guitars. I suspect things have come along quite a lot since then. When I looked for a MIDI interface the other day to connect my MIDI keyboard and drum machine to a more modern bit of software - I'm looking seriously at Cakewalk due to budget issues - I found interfaces that had the standard MIDI ports AND inputs for guitar and voice. I am really hoping someone who is far more current on the technology than me can tell me just what can be done if I buy such an interface.
For instance, will I be able to modify the analog sources by applying effects of various kinds to the guitar (assuming I record it more-or-less "dry")? Will I be able to apply things like autotune or doublers to the voice channel? Will I be able to raise or lower the pitch of analog instruments? Will I be able to edit the analog sounds the way I can a MIDI instrument by holding a note longer or moving its starting point? Or do the analog channels remain pretty much untouchable, meaning they have to be perfectly played when recorded and have all the necessary effects applied outside of the program?
I hope someone who is much more current on the technology can enlighten me so that I have a realistic idea of what is - and isn't - possible.
