I am playing around with Sound Designer in Logic 9, I want to create a really old bad quality audio track, like bad 1920's LP. There is a transistor preset and that pretty much gives me what I am looking for..........but I want to edit the preset, any preset........nothing I do really changes the sound. There is wet/dry mix, and reverb blend but I would expect to see tons more knobs to turn, I don't. anyone help me with this. thanks.
