to add more presence of the KICK
what you can consider is
1. the envelope:
if a sound ( whatsoever that is: kick , pluck, bass ) happens to be dominated from others what you can do about it, is choose between reducing the volume of everything else, or maybe you want to EDIT the sound to make it compete with everything else and something cool to start with is the ENVELOPE of the sound, if you bring up more attack, more sustain on the sound it happens to become more dominant
and you do that by setting different VOLUME ENVELOPES on the synth,
or you may want to use a COMPRESSOR on the samples to bring up more sustain of the kick, o-hat, ride,
2. the frequencies of the sounds:
the sounds that have more frequencies sound louder
if I want a Saxophone like IN YOUR FACE as a LEAD , it already has good enough frequencies, it has good enough presence, and it is easy to do
but something like a FLUTE, may not have too much power to stand in the front, and may easy be dominated from other sounds, but if you add a little distortion you can make it a little more powerful, more frequencies, more louder
it is good to understand the body of the sound, from frequencies perspective for example a snare has: pulse, smack, wires, head, and when you play with these frequencies by increasing and decreasing you get to feel that what is that you want more of that, if its pulse, smack, wires, head
or if we talking about kick drum, is it more boom that you want, is it more punch, more mid, more of high ( 3K, 5k )
but you also need to understand that where the sounds should sit on the mix, if you have something like a pad playing to loud and masking everything else, that can create problems you may want to reduce the volume so other sounds don't have to fight so bad to get attention
so you may simply need to reduce something that is masking everything else, and problem solved
