I have a song that is entirely on keyboard (Alesis Quadrasynth). I have some mixing features on that keyboard (line paning and effects) when the song is played with a sequencer but I don't have the possibility to EQ the individual tracks. The only way I can change the frequency of a track is by going into the individual sound but the filters are not designed to perform mixes (no mid range EQ with variable frequency). Is this a common problem with keyboards or do the new keyboards all have that mixing feature ? If not, do you have to EQ keyboard tracks during a mix or are you just modifying the sound until it fits better frequency wise ?
