LFO Rate Switching?

I use mostly Reason, Ableton and VST's right now...and it seems like all the synth's I've been trying to use to make various wobble beats proves to be difficult. I want to be able to effectively switch between different LFO rates for filter frequncy cutoff. IE, I know that I can assign a rotary knob to an analog LFO rate and go up and down that way or I can assign a knob to different resolutions of time like 1/8, then 3/16, 1/4, etc. But I want to be able to switch between only a few parameters and skip out the ones I dont' want mixed in between....

I'm looking for a way to go span, say 3 rates with different midi buttons or way to toggle between each...so that I can go directly from 1/8 to 3/16 or 1/8 to 1/4 or 1/1 directly to 1/8....etc?

Is there a way to do this with ease or does everyone just record each wobble rate independently and then sequence them together to make it sound like you went from one rate to another dramatically....OR do you try your best using the anolog rate first and then clean up the automation for those rates you didn't want mixed in?

Thanks for any help!

yes you can do this.

read about Ableton live's dummy clips

you could also try sampling each rate and triggering them with drum rack or a rex file

im sure there are other ways

the way i tend to do it is go to the automation lanes on cubase under the vst find the lfo sync rate and hand draw them in

yea duh, i should have mentioned that

if your rewiring into ableton than do all your work in the arrange mode, and open up automation lanes for your synths filter rate, and then add others for cut off and lfo amount if you please

its that little + sign next to the automation lane

then just do as deadly said and draw it in.

but if you like trying things live for fun dummy clips are worth the shot

i'm sure there is some way to config your midi controller like a pad control to send a specific value to the lfo rate like in relation to midi cc
ie: find the percentage approximation on the knob setting for it then relate it like you would on a rotary knob or fader via midi
midi having 0-127 (128 values) and then crunch the numbers to what value it needs to send
say 1/8 sync is at like 60% set on the knob

60 x
---- = ---
100 128

edit: for some reason the x won't space out over the 128 but you should get it

im going to make a preset on my trigger finger doing this

props

just remember midi values go from 0-127 :wink:

I asked the same thing not long back...

If your in ableton some guy showed me a way of switching between 2 rates with a midi button... But the problem with more rates is having different midi buttons for the same knob. Couldnt get round it... If ayone can please let me know!! :D

Here it is:

Here's my roundabout way of doing it with macro's, there may well be a better way but this works:

* Create an instrument rack. It's one of the default live devices.
* Add the synth you're using to the rack (drag it into the marked space on the rack, anything will work, live device, vst whatever)
* Expand the panel for your instrument by clicking the right-facing arrow at the top left of it. Click configure, then click whatever changes the sync on the vst's gui, then click configure again. You should have just created a slider in the instrument panel with something like LFOSYNC as the name.
* Open up the macro panel on the rack (just below the bypass/power icon at top left, its like a little circle with a bent in bit). Click Map Mode, click the slider you just created, then click the Map button under Macro1. Deselect Map Mode.
* Check that the first knob in the Macro Panel adjusts your sync rate. If not, you did it wrong, start again
* Right click the knob, and click edit midi map. Press the button on your controller you wish to use for changing the speed. In the window that just opened up to the left of your arrangement/session called "Midi Mappings", when you press the button an entry gets added here - the min and max values will be the values switched between. The only real way to get the numbers except by guesswork is to, BEFORE doing the "map mode" part of this, drag the slider you created in the instrument panel around and watch the GUI of your synth change, and make a note of the number under the slider when the rate is what you want.

Voila, a button that switches between 2 rates. You can make it much more complex than this, but its a start. Sorry if it dosen't make a lot of sense, I realised halfway through it's more of a bitch to explain than i thought

D'oh, this is for ableton live btw, forgot to mention.

You need this USB LFO switch.

Nice one... :)

Also for Live. I'm using massive as my main wobbler at the moment so this trick wont work with synced lfo's...

Although I am contemplating if this trick might work if you layer maybe 4 instances with different automation speeds or even slight differences in patches to make it more interresting. Then you could map the instances of massive to different parts of the midi keyboard. Only trouble is you would want to transpose the notes of the lower and higher regions (since they sound bad anyway for most wobblers) to match the sweet spot... Don't know if this is possible.

Workaround would be do this with the velocity to 4 synced wobbles from different massives. I know it's possible to map velocity to different instances...

Mind you... These make for a lot of CPU off course 8)

Haven't tried these out yet. But I think these setups are possible if you get deeper into the instrument rack... They do offer cool possibility's :twisted:

If I get this working I might consider writing a tutorial for here...

Good thinking batman!

Although a pretty hefty rack! ( I love hefty racks! ;)

Let me know how you get on.

heres yet another way i remembered when falling asleep last night


in ableton live go to your auto filter

open the midi map

click on the sync rate

now hold down one note on the keyboard your not using, and select another note an octave up while holding the first one.

let go.

you now mapped the speed to a range of keys that will increase per note you play.

you can also do this with anything else, freq, q, etc

UNBELIEVABLE!!! BEST ABLETON TIP EVER!!!

If used along with the method above! This gives full midi control of the rate...

Throw the synth ( TESTED WITH ALBINO IN LIVE8) into an instrument rack > map the LFO rate to a macro knob > midi map 2 octaves on a keyboard!!! BOOMSHANKER!!! LFO RATE INTERCEPTION!!!

I'm not sure how you'd do the assigning different speeds to different midi keys in Fl Studio (would be interesting if anyone knows how),

But what you can do in FL is use the LFO function within the editevents screen.
1. Open up edit events (on any parameter, it doesn't have to be filter cutoff! hmmm interesting)
2.Highlight the bars that you want to control with the LFO
3. press alt+O, and a an lfo screen will pop up, allowing you do draw your automaton with knobs that control speed, cutoff and range. It has these three parameters for the start and the end of the selected bars. So you can have it increase or decrease in speed, range and cutoff as it proceeds.
4. So to chop and change the LFO rate, highlight e.g Half the first bar, and set it to LFO at this rate. Then highlight the second half of the bar and set it to oscillate at a different rate.
5. Since it's an edit events screen, after inputing the oscillations, you can then make alterations by drawing them in with the mouse.

To have one LFO edit events screen that controls both the sub and the mids, open up a X-Y controller in a mixer channel, and assign e.g. volume of sub, and filter cutoff of mid bass both to knob X. Now create the wobble patterns in edit events for X, and you'll have both wobbling crazily and perfectly!

Maybe this way isn't as fun as having midi keys assigned, but you can make some crazy wobbles with it :)

yea that method is key for fruity! i dont know why but the envelopes and automation in fruity sound amazing when you use those windows instead of a linear graph

In reason it's well easy, just assign different buttons to different rates on a combinator (both on and off) and press away while recording.

any suggstions for logic pro and Massive

...I can make a wobble bass but i dont know who to make it change the rate with out changing it on everything
