Funking up LFO’s a bit!

Author Funking up LFO’s a bit!
SarahB
Hi there wigglers..

Just after some ideas to make my lfo’s a little less predictable. I’m currently mixing shapes together with a DC coupled mixer, which works well. Any other favourite ways to do this?

Thanks for any advice on this!
deftinwulf
This may be a kind of "duh" answer, but if the LFO has CV input over its rate and waveshape, you can mult the LFO output and run it back into itself for some LFO->LFO wackiness as the LFO modulates its own shape and rate. spinning
luketeaford
I think logic is a little more interesting-- you can use the greatest (MAX/OR) or lowest (MIN/AND) voltage available. It is a little bit like making a completely new shape instead of mixing two shapes together.

If your LFO has CV control, feeding it back on itself can change its shape so you can go beyond the typical LFO shapes.

If you have bipolar LFOs, rectifying them is cool. Half wave rectification gives you only the positive part. Full wave rectification inverts the bottom part so it becomes all positive and moves twice as fast.

Hi there, have you tried:

- Using another LFO to modulate frequency/ amplitude of the first LFO?
- Putting LFO through a VCA and then controlling the VCA with an envelope or something else?
- Distorting/Overdriving the LFO to change the shape?
- Getting random signals/ noise involved in modulating?

Just try to keep thinking of ways to modulate the LFO, or doing something weird to change the shape and you should find plenty w00t
SarahB
Thanks, some interesting ideas to try here smile

Geiger Counter is great for this! Just trying out all the wave tables for surprising results.

was going to suggest some of these, so i'll expand.

- FM the lfo w/ some other waveshape
- bitcrushing/sample rate reduction gives spikey edges and/or stairstepping (doepfer a189 ftw!)
- mix your lfo w/ another random source
- put it though a s+h with an irregular clock

do all these at once! twisted BOOM!

I like these ideas we're not worthy

I if you have batumi, then the alt firmware pushed it into much more interesting territory...

Yes, I do have a Batumi. I’ll check out the alt firmware. Is it fiddly to install?
SarahB
Also.. just thinking aloud here, but could I mix some noise (audio) in with the lfo shapes in the mixer? Just a touch? Would that add a little random wavering to the mixed shape I wonder?

Thanks for these! I think you just answered my question above!

friggin love that jwm! just got a hypster and lets splosh is near the top of list for next module.

however, all the output jack labels are greek to me and i can't make out what's going on.

aside from more ins/outs, is it doing the same thing these two do?

sorry to hijack, hopefully this is a helpful question to you OP!

Can you say a bit more about what this does? Do you have one? How do you use it? Thanks!

Putting an LFO through a wavefolder gives some added complexity, especially if you start modulating the wavefolder.
gringostar
I typically start with Kermit which is a wavetable LFO, then if I want to modify the waves further I'll mix it with other LFO's or envelopes through a CV mixer, and if I really want to f-up an LFO I'll feed it to the Tyme Sefari mkI which can repeat, delay, sample reduce, and with the ASoT utterly destroy whatever I feed it.

yeah for sure, thats actually my vid - its definitely a little wonky to explain, but at the core of it, its mixing and rectifying...so its takes 4 inputs and then combines positive halfs of certain waves and negative halfs of others in 16 different ways (potentially, depending on what you feed it.)

so in the vid example, its a slow sine and 2 medium-freq random outs from batumi (alt firmware), and a wonky maths envelope...then the outs are going out to a) modulate the lfos and envelope going into it, and b) modulating the hell out of a sparse loop stuck in the morphagene, which is all the chirpy/touchtone stuff you hear and c) filter cutoffs and some other random bits that i can't exactly remember at the moment.

as a bonus, it also handles audio in a fun way, produces a nice rectified distortion, but with both cv and audio use cases, it can def get away from you really quickly...which might be desired. sometimes it is for me!

Also, offset before rectifying -- or mix with a much slower LFO before rectifying so the shape evolves. Or use Cold Mac.

Use an LFO to modulate the phase of another (very slow) LFO.

Running LFOs through filters or slew limiters can do fun things.

Use LFOs (and maybe comparators/window comparators) to trigger envelope generators, sync other LFOs, or clock sequencers (and slew the output) or run them through Wogglebug's Influence input with 0 ID (randomness). Mix, ringmod, VCA etc. the results against each other.

Redefine the shape completely with something like Frames, Geiger Counter, ER-301's Sample Scanner, etc.

Awesome. Modular is so fkin cool! So many different ways to do things.. thanks everyone!

Pittsburgh Chain Reactor is great for unpredictable chaotic yet useful LFO-ness.

My most recent module Ana is an analog wavefolder that is super useful for getting new shapes out of LFOs and does some awesome stuff in a feedback loop with an LFO. Here's a video on using it with maths.

WORNG Vector Space. Feed inputs with 3 CV signals (LFOs, envelopes, joysticks, etc.) and get 17 interrelated CV outputs. Great way to expand your modulation sources, especially in a small system. I have a Malekko JAG, which I think is discontinued (or at least hard to find), bought used before the Vector Space came out-would get the Worng module today.

Also, Triple Sloth is the bomb if you want something less cyclic or predictable than standard LFOs. 11 outputs in 8hp. Finally got one late last year and love it. Check Reverb.com for assembled units if you don't want to build one yourself.

Actually I’ve been eyeing both of these modules but am trying to resist the temptation of buying new stuff! They would both be super useful in my system though.. smile
