New With ??? About My Set Up Options

[torchsong]

Hi, new girl here with lots of questions about hardware and software.
I've read just about everything I can that is somewhat related to my situation but still have ????

I am a cellist and vocalist and want to make backing tracks to play with live and also make demo recordings on my computer. I come from the portastudio school of home recordings so the MIDI stuff is making me nuts!

Here's what I have:
imac running OS 9.2
DX7
Boss DRmkII
Behringer Eurorack
MOTU Fast Lane
Metro 5
OMS 2.3.8 grrrrrrr.....
cello with pickup (although I usually am miked for studio recording)
guitars
cables

I've tried to keep the basic set up simple but am having problems with OMS I think. Metro doesn't seem to like to work with Free MIDI.
I am also having problems playing back audio after recording a track, how am I supposed to hear what I've played to do over dubs?

BTW, I downloaded Pro Tools Free to try it out and just can't get the thing to open (memory error 1,010) so I gave up and went with Metro instead because it was inexpensive to start.

Thanks for any help, this is a great site!

Wait a minute! Did I just hear you say "Norton Utilities"?!?!

Now, I know tastes and experiences vary, and I have no doubt that the next statement may bring out a mob with pitchforks and torches, but I wouldn't let Norton and his Utilities in the same state where I was trying to do music, much less on the same computer. I mean, when people come in here they get frisked to make sure they don't have a copy of Norton Utilities on them.

I will not give any alternative recommendations, because I don't think DiskWarrior has solicited my endorsement, and might even consider legal action if they got it.
