thanks GJ for your reply, but I feel how I have stuff structured really does have a effect on what I need to eq if I have 4 instruments playing at the same time in the hook im gonna have to give or take somewhere along the line unless I have the notes a octave apart
instrument use is not part of structure (the different sections of a song/tune/beat) - it is part of the arrangement/orchestration applied to individual parts of the structure
I use a lot of sampler instruments so when you get up into the higher and lower octaves it starts to lose its sparkle as a instrument.
I don't follow this argument, an instrument that is properly sampled has a base range of notes that it can be assigned to before another sample needs to be used.
Most sample libraries use many different samples per note to replicate different velocities of the same note and use maps to determine which sample gets used where during playback.
All instruments have regions of notes that are more brilliant, more shrill, more dark, more thin than others across the instrument - this is the basic tenet of orchestration: using the appropriate range of notes to achieve the required sound.
Even if you are using a synth instead of a real instrument, the basic idea remains: some of the notes played by the synth will be more brilliant, more shrill, more dark, more thin than others across the instrument. EQ can change the nature of the instrument to some extent but cannot correct poor range choices
Its like if I have a hoover as a bass, a pizzy pluck as a melody, a piano as my counter melody, and a dirty south squill come in for the hook all of those instruments really shine in the low mid and the upper mid range
Maybe this is true, but then this can be said of most instruments, as they are built or designed for reproduction in certain frequency ranges more so than others, even if they are capable of playing higher or lower
I know this is possible because ive heard it clearly on a lot of albums. I know you got vetern mix engineers with a couple million dollar equipment but it isnt anything fabfilter EQ and a couple of waves plugin cant handle.
All of this is true.
However, we come back to a few basic questions (and some suggestions):
1) how are you panning your instruments before you apply eq?
2) what sort of eq are you using in the first place?
3) what ranges are each of your instruments playing in to begin with?
a) if they are all playing in the same octave then separation is difficult - consider moving one or more to the octave above or below
b) even if the timbre (overtone structure and phase/amplitude relationships of the overtone structure) is different for each instrument, they will still be trying to occupy the same frequency range and thus obstructing and masking each other
c) shifting some parts up or down an octave will do wonders for your mix (before you apply panning and EQ)
d) never assume that something must be fixed in a particular octave
e) never assume that you should only use one octave for a particular line to be played - the art of orchestration is about doubling at the octave above or the octave below as much as it is about choosing the key octave to begin with
