okay hopefully someone knows what this **** is that i'm talking about, because quite frankly, it is pissing us (my band) off. we bought the Mackie Tapco Line.USB recorder thing, and it came with this software called Tracktion 2. we have all the stuff set up correctly, registered and all. when we plug the mic into the usb recording device, and record, it comes through our monitors correctly, but when we play it back, it is all jumpy and ****, like it leaves out tiny gaps in the recording during playback. is there any way at all to fix this? is it the tracktion software? any help at all? please?
