Pitch down a kick drum's tail only (envelope lfo question)

kick drum sample.
want kick drum’s tail to go down in pitch.
how do?

because envelopes/LFOs always create a positive numerical output, this can be more of a challenge than it seems it should be. the best way i can imagine is pitching the drum down an octave or so, and then routing an envelope at a positive octave amount, sustain 100%, and use the release as the pitch down part, (or hold etc etc) but can you think of a better way to do it? i’m getting dyslexic over this.

maybe envelopes and lfo’s themselves should go from -1 to +1 and that would do away with ‘bipolar mode’ as well as save a step or two with routing tricks to accomplish the task i mentioned. but i get the wisdom of the bipolar mode for being able to use one LFO for several different sorts of tasks. maybe bipolar mode is the solution i’m looking for anyway. tips?

You can make LFOs bipolar by right-clicking on the circular indicator and chosing that option.

I know that, so i guess that’s one of the use-cases that bipolar mode is exactly for. i’ll try to integrate that understanding more.

You want to modulate the pitch of an oscillator or noise sample downwards? Can’t you just make a normal envelope and turn the modulation target the opposite way? It goes beyond zero into the negatives - if I understood your question correctly…

the part that confuses me here is that if you push an envelope into reverse, then the point between attack and decay (the hold level or 100%) will be pushing the target modulation value down to start with, then the release will gradually relax that value and the result would be an upwards pitch bend at the end, so i guess while using an envelope, the solution is actually to push the modulation positively but to pitch the base value of the oscillator down a few octaves to begin with.


I read your post and the responses to it. Perhaps two oscillators that cross fade would give you the sound your looking for? This might compromise the patch if it already uses multiple OSCs for the body of the sound, but perhaps, one OSC could play the body of the sound, fade and a second OSC plays “the tail.” It could be tricky to set up but might achieve the sound you’re looking for.
