Is it possible to link multiple Tascam 788 recorders? How can I move files between my computers? How do I use a degausser to demagnetise tape heads? What's the difference between the Sennheiser MD421 and MD421 MkII microphone? Can you suggest a good weighted keyboard? Can I copy vinyl to CD via an S/PDIF connection? Can I use my Logic plug-ins with another sequencer? How do digital errors affect the stereo image?
