darrenbkl : ok first of all, as you can see the questions james asked you have pretty much kicked in order as stated on my recording FAQ (I conveniently linked :
http://tinyurl.com/diyrecording )
Recording Purpose > vocals/instrument > mic > preamp > soundcard > USB/Firewire/PCI > PC > DAW
your wants = genre : instrumental rock,sentimental and symphony stuff
your instruments = guitar (apparently with a processor you want a diversed range of clean to rock guitar sounds I assume) and piano . no vox nothing else.
your planned setup = midi for your piano, and guitar input DI recording.
your expectations = acceptable quality. (this one you'll need to learn mixing. raw recordings won't come out magic on their own unless you own some serious pieces of gear)
your budget = not stated, but i'm guessing you haven't struck bigsweep yet.
this in mind now it looks like this :
For Recording your compositions > guitar (DI) /piano (midi) > none > ? (Preamp) > ? (soundcard/audiointerface) > ? (does your macbook have firewire?) > Mac > ? (probably garageband)
I see for a good start you got a pretty nice midi controller there which has USB connectivity to function as a midi controller in your DAW right? so now for the guitars, if you're not looking to spend much, I believe Line6 Toneport UX1 will suffice. (remember that toneport UX1 only supports Dynamic mics, so in case you're considering to record vocals in future with a condenser, you might wanna opt for UX2 at least) reason why I suggested toneport UX cos it's got an inbuilt guitar processor and lots of Softies have it! I'm not a fan of guitar processors, more of a mic up guy , so I got what james recommended the Zoom H4 and D888, but planning to sell off to upgrade soon.
Monitors, because you're recording Midi and Guitar DI processors, you will have no need to worry about "microphone bleed" , you don't have to "isolate your monitoring sound away from the microphones" . i'm sure you have decent comfortable pc speakers to work with.
but if you want headphones my vote is with this : Audio Technica M30fs , available at simlim hungbrothers , website is
www.hungbros.com DO NOT key in "brothers" lol.. I'm at work and it turned out to be a porn site when I spelt it fully..
cheap , good, long cable cord, great sound isolation, nice lows, the mid scoop is deceiving for mixing the mids. long reliability.
villanovajunction : thanks haha. i wouldn't call it wisdom la.. more like "tried'n'tested experience". le experience ..
