Muddy Noise

Im currently making a song with only 5 tracks…track 1 has a kick on every 4 beats starting at 0 (0,4,8,12)…track 2 had a bass synth every 4 beats starting at 2 (2,6,10,14) track 3 is a hi hat every 4 beats starting on 2 (2,6,10,14) track 4 is a clap every 4 beats starting on 0 (0,4,8,12) and track 5 is synth melody…my problem is that the bass synth and the hi hat, and the bass synth and the synth melody all clash and mud up the sound pretty bad, yet i saw somebody make a song on a video tutorial that was quite similar, and his sound quality stayed the same through out…what am i doing wrong?
