Description:

I experimented a little in making dubstep wobble basses.
A test of LFO-Filtering capabilities of LMMS. Conclusion: It's hard to keep your LFOs syncronized with the beat, since they get off very fast. The phase-setting renders useless, because the LFO phase angles are not reset when starting playback. I managed to syncronize the wobble-effect manually, by automation of the cutoff-frequency and massive use of the inertia setting from CALF filters. The straight way, i.e. using LFOs to change the cutoff frequency yields very poor results.

You have to play a few bars with drums and other instruments before starting from the beginning, so all peak-controllers for the sidechain-commpression-effect of the bass can trigger once.

Have fun with it! Note: This is not a finished song.

That's cool :DPosted by: Fiona on 2011-03-10 14:14:38
Cool dubstep very good i like it...

I would appreciate more information on what you've handled the LFO and how, if any track, the instrument, the track editor effects or ritmoAgradeceria more information on what you've handled the LFO as if some clue The instrument, the track editor effects or rhythm.Posted by: Mistertrufa on 2011-03-11 15:07:40
I wonder if i get you right. Are you interested in how i made the usual dubstep wobble sound, or more generally, what I used the LFOs for?

I'll start to comment on the wobble effect.

Normally, you would insert an LFO to the controller rack, set up the desired cycle duration by syncing it with the beat (right click on the knob). Then connect it to let's say your lowpass filter frequency knob. Then adjust the phase and it's done. The mean thing is: LMMS doesn't really syncronize it's LFOs. It just calculates the cycle duration due to your setting. The LFO cant be triggered and run all the time, hence, it is really hard to use them for syncronized filter adjustments.

So I started to try someting new:
The Calf Filter LADSPA has an inertia setting, i.e. fast cutoff changes are damped. So with the right damping, a squarewave will get a sine-like thing. So I made an Automation track ("wobble"), which is actually a beatandbassline, which contains several automation tracks. One for the fast wobbles and one for the slow. And all of them shifted 180°. The shifted ones are old ones, i experimented with. What you are concerned about: I automated the cutoff-setting of the Calf Filter instead of linking it to an LFO. I used very harsh automation and fiddled around with the inertia setting to get the sound right.

I hope, this cures your curiosity.
