Listening to them side by side, I think the thing that I'm hearing is more high-end on the samples you've made. Still, wow, that's an amazing analysis.
Well yeah, if you take into account that the bus chime probably plays back on a crappy small (piezo?) speaker and then was recorded on something like a cellphone, perhaps from a few feet distance, you'd expect to lose some fidelity.

If you want to simulate that, the best way of replicating that, is just going through that process yourself: play the sample through the speaker of your phone for example and record it with a mediocre microphone. Alternatively, look into lo-fi and/or impulse response plugins.

Not saying this sample is worth all that when a bit of equalizing might do, but it's something you shouldn't be afraid to do in general. It provides interesting results that are hard to replicate exactly otherwise.

As for the analysis, a good parametric equalizer with very narrow Q options helps pinpoint frequencies pretty exactly. With a decent boost, poo poo just starts to ring when you hit the jackpot.

This is definitely square waves on a certain oscillation with resonance added. I'm pretty sure there's more than one synth at work here. A very simple 80's sound, and I'll hazard a guess that this was done with a Juno 06.

Not specifically a how-do-I question, but I was wondering, what's the difference between analog oscillator waves and mathematical ones (like most software synths use)? Since I keep seeing that "virtual analog" term thrown a lot lately. Is it minor self-oscillation that's expected from analog synths on sharp waveforms (saw, pulse, etc)?

Honestly, there isn't one. Analog oscillators have small eccentricities and "errors" that are considered to add character to the tone. Outside of something like a Metsonix tube osc, which is designed to be weird, the difference is negligible. The term "virtual analog" came about in the mid '90's when people got tired of romplers and synth manufacturers started making digital synths with an osc->filter->envelope signal path again. It really refers more to the structure than the sound, if you have a synth with a self resonating filter and knobs on the user control side of things then you have a "virtual analog" synth regardless of whether it is designed to emulate analog circuitry. The Ensoniq Fizmo is probably considered to be a virtual analog design, for example, despite being a purely digital synthesizer.
The only tangible difference, with regards to a conceptual ideal versus the machinery used to produce the tone, would be in resolution, bit depth. An 8 bit replication of a sine wave isn't really all that close to a sine wave, but a 16 bit one is.

Oh okay. I'm just wondering about this for a later project of mine. Right now I'm writing a synth app for Windows 8, which is "virtual analog" I guess (I'm using osc->envelope->filter in that order right now) and supports automation of various knobs via envelopes and a LFO.

Later on, when my list of project's done with, I was considering writing a fully modular synth out of personal interest, and was looking for some information on this mysterious "analog sound" a lot of musicians rave about. I'd like to make something able to do GusGus like sounds.

Speaking of which, I've uploaded a demo of the app:

There is definitely a difference in tone between a digital oscillator and an analog one. A mathematically pure oscillator tone sounds very cold and clean, whereas a pure analog VCO sounds quite warm and thick, and a little fuzzy because each cycle is slightly different due to all the minor flaws in the circuit that add up to create additional harmonics over the base frequency.

Most modern VSTs and virtual analog synths have extra fuzziness and harmonics programmed into their oscillator generation algorithms to simulate this, and the effectiveness of this varies from company to company depending on how well they've emulated the instability of analog circuitry (they're effectively adding deliberate flaws to the otherwise pure, clean tone a mathematically perfect tone would have). A similar thing happens with digital vs. analog filters.

The reason why I got rid of my Nord Modular was because after buying a real analog modular and a bunch of other analog synths, I just was not happy with the sound of the Nord - it sounded too flat and sterile, and it can largely be blamed on the fact that it's really just some software running on a couple of custom DSP chips in a box.

This is not to say I don't care for digital synths at all; I use a ton of VSTs (Albino, FM8, and impOscar in particular) and VAs/ROMplers (Novation X-station, Roland SH-32 and JX-305), and one of my favourite vintage synths I own has digital wavetable oscillators running through analog filters and sounds thicker and warmer than most of my pure analog synths (Korg DW-8000). Digital can sound as good as analog, if it's done well. It's not often or always done well, however.

I may be biased, but to me virtual analog means more than just the basic module structure of a synth.

The term came to prominence (the first usage was the silk-screening on Clavia's Nord Lead) as micro-processors increased in power and dropped in price. This enabled non-naive DSP emulations of analogue synthesis that were previously impossible: band-limited oscillators supporting FM cross-mod, sync, and pulse width modulation (features which romplers simply can't perform adequately); exponential envelope curves; LFOs into the low audio range; non-linear frequency and phase responses; non-aliased modulation; etc.

You're sadly right that in marketing terms "virtual analog" has now just come to mean providing a few filter knobs on the fascia, though. However, that doesn't mean my ears and wallet will accept buzzy aliased oscillators, faked self-oscillating resonance, and a lack of smooth pulse width modulation.

Distorted analog filter with the resonance up high, attack on the filter envelope sweeping it up. Very simple to make on something like a Doepfer Dark Energy.

Any insight in modular systems? I know that CV/G voltages go from 0V to 10V, but what about the audio signal, is it also 0V to 10V with the zero at 5V, or is it -5V to 5V or something like that? I'm looking for some info for properly simulating such a system.

breaks
May 12, 2001

In general CV is 0 to X and audio is -X to X. In Eurorack practice whether it's really 0 to 10 or -5 to 5 or -10 to 10 or whatever depends on the module and manufacturer. Some modules have AC/DC switches to toggle between the two. There are plenty of modules that will let you offset an AC signal so that it fits in a DC range, and so on and so forth.

Depending on your definition of a proper simulation, keep in mind that there are good reasons why there isn't one yet. Something along the lines of a Nord Modular is relatively easy (though still a lot of work), but what I would call a proper simulation that lets you modulate everything at audio rates with high quality and includes lots of non-linear effects and so on is a significant technical challenge.

This is not true at all. An 8 bit sine wave has a higher noise floor, but there is no reason it should otherwise be any worse than a 16, 32, or 4096 bit sine wave, as long as dithering takes place whenever the bit depth changes. You can run a full scale drumloop into a bitcrusher set to 3 bits and the loop itself will sound fine if you also send a good bit of high-passed white noise in along with it... There will obviously be a lot of noise with such a low bit depth, but that's not the same thing as the loop itself being distorted.

With "modulating at audio rates" you mean like feeding an audio signal into the cutoff control CV of a VCF should end up in something useful?

I'm planning to run all modules in lockstep for each sample. A bunch of initial tests showed this as possible with several placeholder modules, all within a certain performance envelope.

The only drawback, if you could call it that, is that to prevent circular dependency issues, the output ports will always be one sample behind what the module is doing. Like this I don't need to check for dependencies, and you could loop a signal either way. Each module would rack up 0.023ms of latency, which I figure is acceptable.

So, having an audio signal control a module should theoretically be possible. Some filters become unstable, if you change parameters every sample, so with these I might have to throttle it to every 2nd or 4th.

breaks
May 12, 2001

Yeah, that's a reasonable approach and along the lines of what most software modulars do as far as I'm aware. You can build a great synth that way that will handle a ton of "normal" patches just fine. All I'm saying is, just be aware that it will not come out sounding like a hardware modular when you start getting into very fast (audio to ultrasonic) modulations, feedback patches, and other such stuff that software generally doesn't handle well at reasonable sample rates.

There are a few recent plugins that are doing a much better job of simulating some of that stuff in a realistic way (Diva and The Drop in particular) but they are borrowing some techniques from circuit modeling packages and are very CPU intensive.

Depending on how the CPU load is of larger patches, once this project is in a more advanced state, I may introduce 2X oversampling. Right now it just supports a simple lovely sine generator and an output, since I'm still toying with what the core architecture will be.

Out of curiosity, what is ultrasonic modulation good for? Any results from this would get antialiased away once it goes into digital domain.

breaks
May 12, 2001

With some modules it doesn't do much, or I often find turning up the amount of ultrasonic modulation has similar effects to turning down the parameter it's modulating. Some modules combine input signals in such a way that it changes the sound in ways that don't seem to happen with other inputs, though. The top section of the Bubblesound cvWS comes to mind.

Also sometimes when you have multiple oscillators FMing each other diming the pitch of one of them can get you some cool textures, though in this case of course it's dipping downward into an audible range unless the FM amount is pretty tiny. Mostly I've used it for this sort of thing, making gritty textures to sample and turn into hat sounds.

Well, basically you need a synth that can produce a waveform that sounds like this:



Here I'm slowly sweeping the wavetable position. There is actually no filters involved. This is what the Massive oscs look like:



The sinewave is there to add bass to the sound. M-talk by itself is quite thin sounding.

And the automation curves of the wavetable position. Fast curve to to make the sound have a snappy start..



.. and a slower performer curve to do the sustained OOII sound



I'm not sure if Ableton stock synths have that kind of oscillators available, but you might be able to get some sort of results with a formant filter.

ejstheman
Feb 11, 2004
Hmm, so what I was thinking of was a formant filter is like adding the results from four narrow bandpass filters, with the exact parameters for the bandpass filters coming from some internal lookup table so you get vowel sounds. Then you send something through it that has a lot of activity at all different frequencies (pink noise or whatever). It looks like the way Massive does vowels is by having oscillators at those frequencies, instead of filtering some underlying sound to emphasize them, which still gives a recognizable vowel, but with a more robotic timbre to it. Am I understanding this correctly?

Massive uses a wavetable oscillator, which is basically a bunch of pregenerated one cycle long samples. Instead of modulating a filter, it's scrolling through the samples. There's no way to tell how NI generated the wavetable, but I'm guessing they had a way to edit the spectrum directly.

Feb 11, 2004
So when Friction was sweeping wavetable position, there are like 30 different one-cycle samples that are pre-made by NI to be progressively more like "ou" and less like "ee," and it's not some parameter that he's changing continuously in a pseudo-analog synth? That seems like it would be difficult to duplicate in another program.
