DJ Fresh once said - never go to far with a track without checking the notes used for the sub. Well.. I have this track where the 2 notes in the bass is "in between the frequency" of a bass and a sub bass. The 2 notes used (togehter with F0 which is a "good" note (43Hz) in the bassline would be: The keys D1 (aprx. 74 Hz) and C1 (aprx. 70 Hz) My question: In J Majiks Feel about you 2 of the notes in the higher region of the bassline (which also could be considered as in between notes) is: D#1 (aprx 78 Hz) - only a semitone higher the my - and F#1 which is (aprx 92 Hz) However I noticed he has placed a Sub one octave below to FILL IT UP. Since a bass with notes in 78Hz-92Hz wouldn´t be especially FAT IN A CLUB. The notes underneath D#0 is aprx. 40 Hz and F#0 47 Hz. Would it be a good idea to fill my two notes of 70 and 74 hz using the same techique with a: C0 (33 Hz) and a D0 (37 Hz) Where is the Bottom LIMIT for GOOD subbbass notes? PLEASE ONLY SERIOUS REPLIES! This is how the bass looks with a D1 and D0, would this be reasonable?
