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!

Welcome back!
First things first... Are you able to get the sound of your keyboard into the mac? And are you able to record the sound. Also are you able to playback the sound you just recorded to play back (in metro)? Let's get that working before moving on to the night mare of midi! You should go ahead and run the sound of your mixer out into the mac. That way when you are sucessful at audio recording, at least you won't be totoally stuck. By that I mean you will be able to record vocals, other instruments, and be able to mess around with the keyboard. That will give you something ineresting to do while gstting the midi mess straightened out. Any way I'll wait for you answer to these questions before moving on.
I am assuming that you know that midi is not an audio signal, and that you will have to make an audio connection from the keyboard to the computer regaurdless.
