In my current song I created a bass I really like in NI Massive. The only problem is that in my melody, there are a few notes that are REALLY low, c1, c0 range. It also has a decent amount of mid-range tones in this synth.
When the synth is played in this low range, it causes them to get slightly detuned and makes them sound slow. By slow I mean the regular notes have a sort of bite and feeling as if someone were strumming them ridiculously fast (best way I can describe it). When they are played in this low note range the reverberation or super fast strumming effect slows down more and more the lower it gets. Its almost analogous to someone applying and LFO to the bass at a extremely high rate, but this rate gets lower and lower evenly as the pitch goes down.
This is extremely frustrating because when I raise those notes up an octave they sound great but it totally throws off the melody. I wrote a melody that works well with the sound because of this but if possible I would like to use the original.
EDIT: Here is a clip from the song that shows what is happening. The first part has the really low notes and the second part is the revised edition but if you listen carefully you can hear the slight detuning of the notes in that part. The melody matches the theory of my chord structure... so it shouldn't be this off.
EDIT: One last thing in case anybody knows much about Massive. The three oscillators I chose were a sawtooth (I believe sin/saw 1 with the wavetable position all the way on saw), deep throat, and modern talking (not the overused dubstep method). The last two are talking/vocal/formant type oscillators.
Why does it do this and can it be avoided?
