stereolab moog sound - even possible on microkorg?

Post by lu77 »

i've been trying to get something like this for a while, but i don't even know where to start really. mostly i just pick something rich with a saw wave and twiddle the cuttoff very fast. but it's not the same really.

Try starting with noise, then use a band pass filter with a lot of resonance, modulating the centerpoint with an LFO sync'd to tempo. Then use a LFO2 with a Sample & Hold to modulate the center point to give it that random bubbling sound.

i guess i don't realy know how to 'modulate the centre point' but by fiddling with Mod FX on Phaser with a high frequency, i started to get something.

i started with a blank initialized tone (Shift 3)
noise on full
oscillators off
filter: BPF cutoff:36, resonance:127, filter eg int:0
LFO1: saw wav, tempo sync, freq:127
LFO2: SHift and hold, no sync, freq:127
mod fx: phaser, LFO speed:103, effect depth:127

http://volupt.nu/bubbles-attempt-1.mp3 - sorry audio is from mic not line in.

theres two sounds being generated, the louder one and behind it a quieter higher freq sound,


EDIT TWO
To make the higher freq sound louder, turn down the FIlter resonance, but you'll get alot of noise too.

http://volupt.nu/bubbles-attempt-2.mp3 - in this one the 'noise' is actually from the synth. a hiss.

filter: BPF cutoff:0, resonance:60, filter eg int:-8

EDIT THREE
To remove the noise, bring down the low EQ gain.

low EQ gain:-12

just wiped my settings but will post the FINAL mp3 in a few minutes

http://volupt.nu/bubbles-attempt-3.mp3 -its very quiet and theres still a tiny bit of noise

You modulate the filter cutoff (center) point using a virtual patch with LFO as the source and CutOff as the destination, with mod int to affect the intensity of the modulation. You probably need two virtual patches, one of LFO1 to give the basic 'liquid' sound of the filter sync'd to the BPM, and another on LFO2 with a sample and hold to give an additional amount of random variation to the filter so it sounds like a more natural bubbling rather than something that is precisely repetitive. The amount of resonance and the starting point of the filter cutoff need to be adjusted to use a significant amount of the high frequencies in the noise. Right now your sample doesn't have enough high frequencies being emphasised. Don't use any effects at this point - stick with the basic synth structure.

hmm okay i'll have another go. patches are a bit beyond me at this point but your instructions are clear, so it might be a good point to delve in.

when recording the final result, it became REALLY loud once, like a glitch in the machine, but is now back to it's tiny low volume, i have uploaded that third mp3 now. (and saved the setting!)

i really appreciate the help you've given me. i know what half the things do, I used to deconstruct the presets on my Poly-61, but the microkorg has quite a few extras. like filters. and i havent delved into noise much at all. so learning to built an odd sound like this has been really instructive.

Noise can be very useful, particularly to get natural sounding wind instruments like pan flutes, or all kinds of percussion. You can usually tell when noise is being used as a source when there isn't a dominant root note that stands out - because all the basic waves - saw/sine/square - have a dominant root, so the harmonics are still dominated by the root. Noise is useful when you want to emphasize any part of the spectrum, such as with filter resonance, without an underlying tone.

Think of helicopter blades - these are just wind noise that have a particular resonance due to the blades cutting through the air, and part of the sound is due to the doppler effect - the blades are moving towards you half the time, and moving away half the time - causing a slight warble in pitch upwards and downwards based on the RPM of the rotor and the number of blades. The helicopter engine itself has a different sound - either turbine whine or piston engine. Water/liquid sounds are also due to how the liquid interacts with the air around it - from water falls that sound like a full range of noise, to ocean wave crashes, to individual water drops - all just different frequency ranges of noise with different periods.

Virtual patches are extremely important because they are the key to modulations that are not built into the normal signal flow. They open up a whole new world of variation to the basic synth structure. The best and most interesting sounds usually have virtual patches to modulate the sounds in unique ways. For example, you can change modulations based on keyboard track and velocity, so that you can get a much more dynamic sound based on how hard and where you hit the keys.

i knew noise could be part of something, like a wind instrument, and i knew it could do percussive things, but it never occured to me that it could be that bubbly sound as well. on reflection it is almost like a very slow distortion buzz, so it does make sense.

am back from chores and will now try these patch-whatsits!

Okay 4th attempt:
noise on full
oscillators off
filter: BPF cutoff:43, resonance:110, filter eg int:0
LFO1: saw wav, tempo sync, freq:127
LFO2: SHift and hold, no sync, freq:127

Patch 1 source LFO2, dest cutoff, mod int: 31

http://volupt.nu/bubbles-attempt-4.mp3

LFO1 for the patch didn't have any effect, i tried atch 1 LFO1, patch 2 LFO2, and all variations in between..

it's amazing how close this gets to the sound of a frying pan if you tweak it that way. I tended to want some depth in there, so it's not as high as it could go, this keeps the tempo from getting too fast and fizzly, but has some hissing in the background. This is definitely a sound i've been trying to etch out of the microkorg since the day I got it, i used to just fiddle with the presets and cutoffs to hear it in the background behind the tones. SO it's nice to have a whole channel to itself now!

when I go back to the original stereolab moog sound I realise it's a much more regular, consistent sound and maybe slightly more tonal...

I realise this is an old thread, but I stumbled upon it searching for tips on how to make a bubbling sound on the MK. And, as so often happens, I found it on the MK itself by tweaking a totally different sound. I specially tweeaked the filter freq and resonance. I'm under the impression that it's actually the oscillating filter that you hear. As I listen carefully, I can still hear a reminensce of the original sound. Anyway, if it interests you, enjoy:

oh i will always monitor this thread because it's a sound i'm obsessed with!!

I actually have staryted lay-bying a Little Phatty Moog because it has a preset very much this kind of sound. Well that wasn't the only reason but it was a clincher!

But i'll definitely have to finish off that MK preset... I've sort of got two presets and i have to meet them in the middle somewhere.I've bookmarked this thread and will post the results for others.

How did you get your sound exactly? it is particularly bloopy and nice! Was it based on a factory preset? I'm after something a bit faster but I think you could manage the same thing as you say tweaking it a bit further.

Yes, I think it is based on a factory preset, some "normal"synthesizer sound. I hope I still have the settings on the MK and if so, will make a .prg file of it to show you the settings. I think it's no problem to make the bloobs go faster. I'll let you know if I succeed in saving the bubbles :)

Well, the bad: I seem to have overwritten the bubbles.
The good: I think I have some recipe to create these sounds, driven by the idea that it's filter oscillation. Of course it may very well be that the MK cannot have an oscillating filter like your (very nice :P) Phatty, because the MK is a DSP, but the idea stays the same: "resonancing out" the entire original sound. I tried this on presets 3 and 5. (Layered presets like A11 probably don't work well).

OK choose for example A13 and turn the edit select dial to FILTER
Now: knob 1=bpF, 2=55, 3=127, 4=+55, 5=+63 (so: resonance max, mind this is knob 3, a bit confusing because "resonance" is written over knob 2 on the MK). Now the original sound is gone, turn knob 3 to left and right a few times to get the idea.....
THEN push arpeggiator button, and set edit select to FILTER EG.
Knob 1=103, 2=55, 3=15, 4=0, 5=on or off, now tweak the LFO's etc, enjoy!

oh man, i didn't see your reply here! i've lost all my factory sounds at this stage, so i'm going ot have to try from scrtch again... hoping that i can apply the same principles to the LPas well which i swear made the sound whilei was messing around in store...

anyway thankyou for your help, i'm going to try to follow our discussion from the beginning and see if I have better results.
