When I bounce tracks on my tascam 38, if the destination track is directly adjacent to any of the source tracks I can barely turn it up past -20 or so or i'll get this strange high-pitched feedback like sound that suddenly oveloads all the VU meters. Same thing happens if it's two tracks away as well, but I can turn it up much louder before it does so this isn't really an issue. Is this just something that I have to watch out for and deal with, or is there a way around it?
