my sub bass just sounds wrong to me!

[thierry_le_dj]

i've been playing around with my sine bass for sometimes but every time i try to make a normal sine under neath a mid range bass or even by it self it gives a big booom sounds instead i was a normal proper sub that i can feel for some reason the sub is only on the 1st kick then it cuts off by the 2nd kick
am not sure why its doing that and what i am doing wrong

for example check it here on this track from 1:52
Soundcloud
the bass here at 1:52 sounds like a big booom but i just want a normal sub vibe, straight sine bass

anyone know whats wrong with it?

It sounds to me as though you have clashing frequencies.
Check that you don`t have overlapping bass frequencies in the same range playing at the same time.

cheers but it's not
just one bass there nothing else
am not sure
am playing around with it now i still don't know

[Electric_Head]

What I`m meaning is, do you have the bass note starting while the previous note is playing?

wat ma boy electric head here is saying...listen harder.

sustain?

Wow...I didn't realize I haven't posted any introduction! Excuse my post!

Yeah check your amp envelope. Its got some decay. turn your sustain + Decay all the way up, then it wont loose its initial volume after the attack
