Thanks, Stephen!

In a VERY oversimplified way of explaining; doubling the value of the cap in the integrator section of the LFO will halve the speed.

So, in Stephen's scheme, that would be the 33uF in the IC4b feedback, yes? I can just add pads to put another cap in parallel with it. Folks can install sockets and try different values to see (hear) what they like best.

Thanks!

Hi,
Nice circuit work. You might need to make the pads a little fatter though, otherwise drill bits might eat them up.

Yes. 2 pads seems like the way to go. After "auditioning" cap values, wiring up a switch would be EZ as can be.
All the Best!

It was a few years ago that I drew that Ton!!

ooops, I thought it were a different circuit - hadn`t compared them...
(didn`t know it was yours, even)

I'm planning to have these fabbed... no drilling.

Thanks for digging that up, Ton. Nice drawing too, Stephen. At least a SAD1024 is easier to find than a SSM2040 (and more affordable, too!).

Does anyone know where you can hear a good example of what 'bounce' sounds like? The descriptions sound interesting, but I'm not sure I've ever heard what it actually sounds like.

Thanks!

Hey Charlie,

I will do some Spice simulations on the various LFO versions this evening. Should give us a clue of the frequency ranges they cover.

Again, thanks for all your work!!

I did the LTSpice simulations of the rev3, rev4 and Stephen's MI LFO.
Here are the three schems in comparison:



The calculated frequency ranges of the three LFOs are pretty similar.

Rev3: 40 mHz to 18 Hz
Rev4: 35 mHz to 13.7 Hz
Stephen: 45 mHz to 9.5 Hz

Specs of the original: 30 mHz to 10 Hz



(V(rev32) is for rev3 with double integrating capacity)

As predicted by oldschoolanalog doubling the integrating cap halves the speed (just checked for ver 3: 20 mHz). Thanks for the formula btw! :)
Interestingly, the slow sweep frequencies are all exactly at multiples of 5 mHz. I suppose this somehow correlates with the 200s ( Took ages neverthless ;) ) I used for simulation time and the method of calculating the FFT. Maybe someone can shed some light on it ? :)

These are samples from my TDA1022 Standard Electric Mistress  with bounce, which give an idea of what it can sound like.

Fortunately, the ADA Flanger has CV in :)

I'm not sure that the placing of the bounce control is understood. I'll post a drawing I did speculating what an ADA circuit with bounce might look like.

Not to be a buzz-kill, but the bounce thing (while interesting) doesn't sound like something very useful (musical) to me.  :icon_neutral:

Well, it's useful to my ears in just one setting where the sweep goes up to the top, starts to go down and then sweeps up and down again. The sounds on the samples are extreme I would agree and useless in a band situation, but aren't 90% of effects???
