I just recently started working on this track and once I had finished the piano section, I added in some drums and a synth to beef it up a bit. It sounds fine in reaper when playing back but once I render it or bounce to disc and upload to soundcloud, the cymbals get this weird shimmering type sound happening which I don't know how to get rid of. I initially used a rhodes organ type sound instead of the keys but it was having the same sound on it as well so I changed it to a piano and now it's not as noticable, but with the drums its quite obvious on the cymbals
. I played the track in windows media player and I'm getting the same problem! Plugins used are SD2.0, Dimension Pro, Taurus, audication compressor and Waveslimiter and altiverb on the master. does anyone know what it is/how to fix it?
