something new or get a mixer, but I don't have good acoustics in my studio so I don't can't sacrifice any more sound quality. What should I do (I'm on a low budget)?

Its a mixer (or new multi-input soundcard with 8 ins) theres not really any other proper solution to your question. Workarounds: 1. Overdub (but I'm guessing you would have done that already if you wanted to!) Split your drum part into 2 parts and record them separately. I'm not really a drummer, but I'm guessing you could do hat, kik, snare on one take and then Toms and cymbals on the next. This will be a little tricky, but thinking about the parts seperately will be good for your drumming head too (though might give you a headache initially!) 2. Substitute some live drum parts (sacrilige!) Leave out how ever many mics you need. If say 2, I would sub the kik and snare with synth parts. Program these parts and then play the full kit over the top, recording the other parts of the kit live. The sound of the kik/snare will get picked up by the mics you are using on the rest of the kit. This "spill" from your kik/snare into the overheads etc will help the synth part sound more live (as long as the timing is good & well matched!!) Note: bad room acoustics and good recording equipment = bad sound. The better the equipment the more you "show off" the bad sound. Think of it like a $20 cd player through the best speakers ever - all you'll get is a good quality reproduction of a bad signal. I know your budget's tight but we used to use this - really good (depending on why the acoustics are bad). Or just look into it a bit and see if you can't improve or deaden the room sound on a budget (be careful of overdamping - you'll kill the cymbals!) http://www.sweetwater.com/store/detail/PSSGrayPoly/ Hope that helps!!

i don't recommend splitting up the drum parts as one of the undocumented aspects of recording any instrument is GROOVE. If you chop up those drums then you loose a lot of groove : (...a mixer is a great solution, as is updating your audio interface...i have a presonus firepod and it has 8 mic inputs (2 of which have 48 phantom power) outside of buying a new unit or an electric drum kit, there aren't really any efficient ways to do this.
