That sounds like one of those autotuned cats on Tiktok.

It has an 303 filter with 12 and 24 db. I mean the 303 deluxe. Its not just standard LP filter. Can se if i can make a video.

2-4 pole filters are standard filters
Either way it sounds nowhere near a 303
If a 303 is a strawberry cake and a tiny bit of distortion is whipped cream , you’re showing a bucket full of whipped cream with a strawberry at the bottom of the bucket.

Pls explain more about the 303 sound. I made this one most for warp sounds. And its free.



Mybe its not close enough. Or mybe i dont doing it right lol

I have zero technical skills to explain why it doesnt sound to me exactly like "the best" emulations (which is totally subjective), or phoscyon or whatever but your plugin certainly seems cool, thanks for making it.
Like i made a lot of patches before with massive and fm8 etc trying to get specific tb303/acid sounds, and while i certainly made a few nice patches, these emulation model things (circuitry?battery, defects? mojo? vibe? hahahaha^^ ) that i have no control over in my synths.
And so the slight filter differences etc etc, all add up and my patch ends up sounding different no matter what.

So by chance?, when i demoed phoscyon, it had exactly the specific sounds with the specific amount of THAT flavour I was looking for. It's the point of all real synth emulations right^^
But's it's gonna be different for everybody what exactly they're looking for^^

Back to your synth, for someone looking for a quick acid vibe, with a bit of tweaking, it seems very usable. Maybe show a bit more the dry sounds?
Thanks again for the effort!

What made 303 so popular and used by many is its sound ofcourse but also its quirky programming of patterns. Yes, it is crappy by today’s standards but, it is part of its flavour
All those classic 303 bass lines were created using 303 only.
Are we all getting bit lazy these days and relying on technology as it is today?

[RugerioDelStereo]

Atlatnesi, plenty of the first wave of acid producers used effects on their 303s. Delay, reverb, distortion, compression, if that's what you mean.

Still, programming a 303 was (and is, I have the TD-3) like some weird cumbersome occult ritual!

I'm not buying this revisionist lore. It's relatively well known that often 303-lines were produced either by using the original 303 random trick which is to remove the batteries, or, by simply mashing buttons somewhat randomly. Programming the 303 was always shit, even when it was new. It was never admired nor embraced as such. It was sometimes accepted, but often avoided. I can't find any quotes at the moment, but I have read numerous quotes to this effect over the years.

ABL3 for me. Just stays the most convincing no matter how much you process it.

Nahh , plenty of the first wave producers used the 303 dry ( bit of reverb )
Also , I believe that most of the memorable basslines( showcased in the video ° ar) are anything but random .

Pls explain more about the 303 sound.

There's a couple of things that are somewhat unique to 303 (and clones). First there's the sequencer that produces slides and accents that change how the rest of the circuitry behaves. Slides are nothing too special, it's essentially just a one-pole lowpass filtering the 1v/octave pitch control signal when slide is active, but what is more interesting is the accent that is very dynamic and can even be activated half-way through a slide.

Accents boost volume, but it's the filter control side of accents that is quite unique, because it sort of smooths out the accents depending on resonance, making the filter produces a rather unique "wow" sound at high resonance. It's also not reset between notes, it's a simple circuit, so if you have multiple accents at high tempo each accent sweeps the filter a bit higher than the previous one, up to a point.

The filter itself is a diode ladder with a very gradual slope at low resonance and much higher amount of feedback is required to bring it close to self oscillation compared to say a Moog-style transistor ladder and it distorts in quite a unique way. It's not necessarily very obvious distortion with the simple waveforms produced by the single oscillator, but the distortion affects the resonance behavior and the filter has quite excessive "DC coupling" to the point where it's actually sort of a band-pass filter with significant drop in the low range; this is why the waveforms coming out of the thing look so heavily curved.

There's also a lot more volume drop with increasing resonance compared to a transistor ladder, but this is partially compensated by the circuitry feeding more of the filter output to the VCA at higher resonance. The VCA itself is not necessarily totally linear either (it distorts a bit), though I guess it mostly distorts the attacks, especially those of accented notes. Overall though, without an external distortion unit the thing sounds quite tame.. but it does produce waveforms that tend to produce nice distortion when put through a distortion unit.

Finally there's the square wave. The saw wave is about as standard as they get (though not necessarily the highest quality), but the "square" shaper is quite funky. It produces a sort of half-pulse half-saw type of waveform that is dynamic such that the pulse width varies both by frequency (in steady state) and also by short-term history of what the frequency was previously.

There's also a few other minor things, like increasing envelope depth also turns down the base cutoff so that you are much more likely to stay within the sweet spot if you just tweak the knobs at random while it's playing, which is great for performance, but .. overall the unique square, the unique variant of a not that popular diode ladder filter and the unique accent circuitry are probably the most obvious things that give 303 it's "special" status in acid.

The TD-3-MO is very close to the original and additionally it can get beyond the usual 303 sound. Best of both worlds?

This needs to be published.

The MO is great, but if you want a range similar to the original, the TD-3 will give you that. Audio samples as compared to an original 303 here. You can decide for yourself how close they are. Other emu comparisons are also available.
