I always have trouble with compression.I tried to use it on a recording I did and you can listen to it by going here: mp3.com/Maligna. That is my band. Well anyway, I use a Roland VS840 and dump tracks one by one onto my computer using the Acid pro 3 and and then I start editing from there.But I used a regular stereo 8th inch cable from Radio Shack to down load into my computer into a Creative Labs Sound Blaster card using the mic in line,lol.Pretty cheap i'll say but oh well,when in rome. Well the compressor thing.I can't seem to really know where the use of one comes in.Can anyone help this ttroubled soul?Thanks.
