Question

I have a ghost track when I record Audio Tracks?

I'm using Logic 9 on Macbook Pro running OS10.6.7. I have my audio routed through a M-Audio Fast track, however I have recently begun to notice when recoding audio that thre is a ghost of either the click tracks or drums when recording guitars and a ghost of all tracks when I record Vocals? I've not changed any settings and have had the devise for a number of years, used on 3 Macs and both Garage Band.

I have tried 2 different guitars with different pick up configuration fearing the pic ups may by "Microphonic" and have tried with no power supply in case of electric interference?

Whn I use internal input/mic, everything appears normal, however I cannot connect a guitar this way as I don't have the kit to trouble shoot?

Any Logic Pros out there shoo may have experienced something similar?

I understand the fast track is not the best interface, but it has work for me up till now.

Logic Pro, Mac OS X (10.6.7), M-Audio Fast Track USB

Is the "ghost" on the audio tracks with the program material or just in the headphones/monitors?

The ghost appears on the recording, it would of of course appear in monitors and cans when recording otherwise I wouldn't be able to hear what i'm recording.

I Have Samson monitors which are powered from Fast Track and Sennheiser HD205 Cans which I use to monitor when recording either guitars or vox?

Does this make it any clearer?

The ghost in the vocals can probably be explained by headphone bleed being picked up by the mic. As to your guitar, I have had a few situations where my guitar picked up audio from my near field monitors which were up turned up loud and I was sitting very close, but that's a rarity.......

If there is an M Audio user forum you might be able to get some help there. Is your interface new? Maybe its a hardware problem.

Someone else reported the same problem 2-3 weeks ago, I think they were using the Mac's internal Line-In audio.

Exact same symptoms, also a Mackbook pro I think.

@Data Stream The interface is several years old, but I have only started to experience the issue on the latest track i'm working on. Always start from a blank project too.

I'll check the M-Audio Site and have a mate coming round in the week with a different interface to try to isolate if it is the fast track?

@Pancenter I've tried internal mic but no line in, I couldn't replicate the problem this way, Maybe I'll try recoding data from iPhone into logic via lin in to see is I get the same results.
