Bleeding tracks

[bootz42]

my set up is instruments into a mackie 1604 vlz-pro going into an echo audiofire4 and a mac with dp7. set up with 25 stereo tracks. outputs to bus 1&2 into two aux channels. Aux channels out to the board.



I am getting bleeding when I record.
I am recording one track at a time.
I record onto the second track ,and monitor the recorded tracks.
With all my mics muted, I am using headphones, the second track is guitar and the piano from the first track that is playing into my headphones are being recorded onto the second track. Both tracks have their outputs going to the aux channels for comp. and reverb. then out to my mixer and to my headphones.

I took audio engineering classes about ten years ago so please be patient...what engineering "trick" did i forget?

Usually the best way to get audio out of the Mackie when tracking is to use the direct outs on channels 1-8. That will assure isolation.
Another way, but which is more prone to operator error, is to hook your Mackie sub outs to the A/D converters. Then you click in the sub switches on next to your fader when you want to record them.
The other thing that is usually done is that Mackie channels 1-8 are used for preamps and sending (because they have the direct outs) to the computer inputs. And Channels 9-16 are used to monitor playback from the computer outputs.

So you think the bleeding is happening on the analog mackie end and not in DP7?

My D/A converter has only 2 inputs and 4 outputs. so taking the 4 direct out from channels 1-4 won't work. That was one of my reasons to send them to the mains out and into the comp. I could send the signal to sub 1-2~into the comp~ out to the mackie and to the Mains, but what is the difference? I'll try that first thing tomorrow morning, but what are your thoughts as to where the bleeding is coming from?

thanks for your time and sharing your expertise.

My setup is somewhat similar. I haven't experienced track bleed per se however there have been many instances where I routed a signal incorrectly and that has usually occurred on the outboard mackie. Is this a new configuration for you? Perhaps you are routing signals to channels or busses unintentionally.

What I'm saying is that I think the likelihood of 'bleed' occurring is low unless you've got some really hot gain settings somewhere. It's probably a routing issue, from your description. (Hope I haven't introduced a red herring.)

I think it is time for mackie to have "dummy" L.E.D.'s on every button. I did, in fact, have the "assign to mains" buttons depressed on the sub out 1-2. But why I didn't get a ton of feedback I still don't understand. Thanks for your thoughts!!!!

You can send the audio you are recording in two directions. Use the the direct outs to get an unaffected signal to DP. Also, send it to the sub output if you want to hear it with compression if that's how you set it up. Alternatively, you could use the main inserts and put a compressor there. There's no way to record and monitor with the same compressor and keep tracks isolated.
