If I use the Delta and a Midisport will I have trouble configuring my computer to use both simultaneously?
Shouldn't be any trouble at all.
I´ll be recording R&B, Hip Hop and Soul which means that most of the backing will be done by MIDI instead of audio.
Really? I thought you would be heavy with loops doing that kind of stuff...
You
dorealize that the Delta has no MIDI synthesizer on it? Do you already have any outboard sound modules? Or are you planning to use VSTi softsynths?
By the way, in your original post you said:
is there any way of doing this without a USB connection? I.E. is there an "all in one" professional soundcard?
I'm not sure if you
want a USB connection or not. There are several MIDI interfaces that use parallel or serial ports and some in PCI form that take up a slot in your computer and have their own ports on the backplane. There are also some "all in one" units that have audio interfaces
and MIDI interfaces on them, either as a PCI card (plus usually a breakout box) or with USB and now even FireWire I/O. Lots and lots of choices, of course depending on budget. Instead of the Delta you might consider the M-Audio Audiophile (2 analog ins and outs on RCA jacks, plus a MIDI interace, $229 list).
While on the subject, I have an MDMX4 (4 track) lying around with no use. Should I use it as a DI box before running my vocals through the audio input of whichever soundcard I get?
Well, you
will need mic preamps, yes. The 4-track can work for you there, though it might not be the best choice in the world. Try it and see if its preamps work out for you.
