Hi! Budget? That will play a HUGE part in what u r asking. What computer do you plan to use? Will you be able to dedicate one for Cubase use?
For doing what you want:
Computer (since Cubase is host based, more power=better)
Sound Card (high quality=$$$)
Converters (once again, quality=$$$, big time. )
Pre-amp(s) (getting mic'd sound in; if doing drums, and want max flexability, figure on at least 10 channels; I would do 16 channels, using a single 8 channel and mix and match for the rest)
Mics (couple vocal mics, lookin at about 3k for quality drum mics, and a couple "multi-purpose" mics)
If "mixing in the box," dont need to worry about a mixer, and dont need a mix down deck. Otherwise- more $$, and depends on what you want.
Outboard- once again- staying in the box? Otherwise, depends on wants and needs.
DVD recorder in computer for back up.
Quality mic stands, shock mount(s), wind screen(s).
Furniture to house it all.
"Average to good" is really point of view. To me, average to good would be a budget of at least 50k. Pro would be a min budget of about 500k-600k, and that would be "slumming" it on alot of things. Average to good consumer level:
AMD based computer, dual CPU even better.
RME card, and convertors.
one 8 preamp, and a couple 2 pre units (Great Rivers, Grace, Earthworks, etc; depends on whther you want colored sound, or clean)
For mics: Audix stuff for drums, SM57's, AT4040, TLM103, SE's- there is a wide choice here.
Patchbay(s): dont really need a mixer with all that stuff, just patch in, mix in box, good to go.
Good mic stands pay for themselves when the mics dont come crashing down!!!
Hope thathelps a little
