Airwindows

ZRegion2 (and ZRegion)

TL;DW: ZRegion2 is an Emu e6400 style Airwindows Region filter, with coefficient smoothing.

Here’s one I might be needing in future, so I’m putting it out for everybody to have!

The Airwindows Z series filters are kinds of digital filtering, with sampler hardware emulation put on ’em for added color and vividness, plus a staggering capacity for gain (folks using the original samplers often internally distorted sound with gain boosts in order to get maximum color out of the Emu filters).

But what if there’s a filter type that didn’t even exist on the original device?

ZRegion is that filter. The original Airwindows Region wasn’t written in the context of an Emu Z emulation, more like just experimentation. It uses the cascading filter stages and distortions in an interesting way: you’re using bandpass filters and distorting them, but Region lets you stagger the bandpass frequencies so that you’re successively distorting through series of different filters. A bit hard to explain, but it lets you distort on midrangey frequencies and soften into the bass, or start out with bass clipping and then exaggerate that effect with higher frequencies.

The reason I might be needing this one is, I can get pretty killer bass tones using it. I’ll set the first filter higher for midrange articulation, set the last filter very low for heavy bass mojo, and it’s instantly a bass-amp type of sound. And if I intend to leave the setting as a fixed setting, ZRegion will give me that with the same flavor as my other Z filters.

But if I want to automate or move the controls as part of the mix…

ZRegion2 comes out at the same time as ZRegion, but note that I’m still putting out ZRegion. This is because ZRegion will always run at lower CPU than ZRegion2, because the first plugin doesn’t do coefficient smoothing. It’s for if you have a fixed tone setting to use, OR if you want to have a slight glitchy/zipper-noise quality on some audio and you’re moving the controls.

If you’re going for automation, the Z2 filters are the ones that interpolate the coefficients across the sample buffer, meaning they’ll make control changes smooth. No crackling! This eats more CPU, but a lot of the fun with these filters comes from actively manipulating them. The original sampler never had a Region filter type, but now you can make believe it did, and produce aggressive and textural bandpass-y effects across a broader range than the original sampler’s ZBandpass. Hope you like it!

PitchNasty

TL;DW: PitchNasty is a primitive pitch shifter that also has primitive time-stretch artifacts.

PitchNasty.zip(615k)

So this is a bit unusual. Though this is a sound mangler, there’s no bit crushing here, and in fact most of the time it’s delivering a very high-res immediate and punchy pitch shift, super clean and tight.

It’s just that the rest of the time it’s throwing a nasty, loud sample-glitch, at audio rates. No, beyond that. It’s throwing digital trash at you so hard it becomes a musical note!

And therein lies the secret of PitchNasty. This plugin brings you the heart of old school digital like your classic Akai stuff, back when they did not have the luxury of doing anything elegantly or nicely. Instead, you got things like time stretches that just plain looped a tight time cycle and overlapped it, producing a weird digital honk. Some folks really seem to crave that stuff, and there’s a reason.

Turns out if you do that, your results tend to be very punchy, direct and intense, except for the weird robotic overtone that’s welded to the sound like it’s a musical note. Things like drums love being timestretched or repitched in this way! It’s a whole retro tone, which PitchNasty starts off with. The crossover is very slightly ‘clever’ in a way the retro stuff isn’t, for the purpose of making it sound more retro and less DAW-like: it keeps the presence very high while slightly masking the high frequency edge of the ‘note’ you get.

But then PitchNasty goes way beyond, in that Airwindows way. You’ve got two pitch controls, one giving you note intervals in half-steps, and the other being a pure pitch bend. They stack, for really high or low bends. Then, there’s a control that’s the same as the classic Akai method of setting the sample buffer size… but for this one, you specify the buffer as a musical note (six octave range). Set it insanely high and you’re basically not able to pitch shift anymore because the buffer’s too small, set it insanely low and it barely registers as a note anymore. And then after that, how about a feedback? How about a feedback that can be cranked to more or less constant regeneration? This gives you horrible wonderful old Eventide noises of many descriptions, or you can use traces of it to make your existing sound more complicated and harmonic-dense.

And then the whole thing’s followed by a Dry/Wet, and you can see that PitchNasty sticks so tightly to the underlying sound that you can get it acting like a giant flanger or strange overtone generator. And that’s the other secret of the crude old Akai-like time/pitch processing: when you don’t have any RAM or CPU to work with, you can only do naive primitive things that happen to sound really immediate, direct, alive. It doesn’t lose the impact of a drum track. If you set it up to thicken a snare by applying, Eventide-like, a 30% layer of pitch up (or down, with feedback), there is no flam or hesitation to the sound like more sophisticated algorithms would have to do. Instead, it’s just THERE in the sound, with a hefty dose of digital gnarliness, but woven right in to make a very 80s composite sound that’s huge and fierce.

If you would like to use this as a time stretch, what you should do is open the source sound in an editor, change the sample rate without resampling until you have the new pitch you want and apply that, resample it back to what your working sample rate is (use a good resampling method, you don’t need to use a bad one), THEN use PitchNasty to re-pitch it to what the target pitch is. That’ll give you the time-stretch artifacts, because they are really just pitch-change artifacts used in a different light. Hope you like PitchNasty!

Pockey2

TL;DW: Pockey2 is more efficient, more intense lo-fi hiphop in a plugin.

Pockey2.zip(620k)

So this is pretty rapid iteration. I’d been struggling with getting Pockey to willingly do 12 bit: the algorithm didn’t seem to like it, even crashed when I tried to go for 16 bit. Turns out it was counting bit by bit in order to do the analog bitcrushing thing. And there was another way to do it… but then other things had to change… and then other ideas started to happen…

Suffice to say, it earned its new version number.

Pockey2 takes the basic concept of Pockey and brings in an entirely fresh character, while running way more efficiently. Instead of analog-style floating point bitcrushing, it’s integer… but you’ll find the difference between 5037 ‘stairsteps’ and 5038 ‘stairsteps’ will amount to about the same thing, just way more easy on the CPU. Still uLaw, still a big sampler-esque texture, now letting you go from 4 bit all the way to 16 bit at no CPU penalty. There’s not a lot of point running 16 bit here as it’s still uLaw, but in case you’re looking for just the lightest possible ‘sampler’ touch on your 24 bit DAW track, you’ve got it.

Instead of analog-style floating point frequency crushing, that’s integer too… which means the adjustability of the super-bright frequency crushing will be ‘steppy’, not allowing fine adjustments especially if the DAW’s at 44.1k. But if you’re running 96k, you get a much broader range of adjustment! And you get to frequency crush down way lower than before… and the tone! Another reason Pockey2 is a new version number is that, while the tone of the frequency crush on Pockey was interesting and vibey, the stuff you can do with the different-sounding Pockey2 is beyond belief. Experiment with the DeFreq control and see what you get. There’s a little bit of the ‘sweep the digital sampler cutoff point’ still there, especially at deeper frequency crushes, but Pockey2 shines when finding just the right spot to entirely transform a sound into pure lo-fi hip hop classic sampler madness. Even more than the original Pockey, this one can completely transform a sound into retro digital.

You can use both. If you like Pockey and find its CPU use too heavy, DeRez it more, it struggles to get to high bit depths. If you like Pockey2, it doesn’t struggle with anything except sometimes with slowly sweeping a frequency crush way up high. I hope you like both Pockeys and find your best use for them :)

Pockey

TL;DW: Pockey is 12 bit (and under) lo-fi hiphop in a plugin.

Pockey.zip(617k)

This plugin is designed to give you the most vibe possible out of a particular target: 12 bit uLaw-sampled lo-fi hiphop. It’s based on earlier plugins like DeRez and BitGlitter, but is tailored to deliver just the right kind of warm fuzzy texture like an old sampler… or the Pocket Operator sampler that’s a lot more accessible than retro 12-bit is.

Pockey uses uLaw encoding to stretch 12 bit sampling to where it sounds pretty nearly CD quality, except there’s a whole vibe and texture you get through having the soft, delicate sounds slightly low-bit and the louder sounds even more crunchy than that. The lowest setting on the resolution slider is exactly 12 bit, and everything higher than that gives you progressively more lo-fi in an ‘analog bitcrush’ mode, meaning that it will gradually build as you turn it up, rather than jump from step to step. That way you can fade smoothly from 4-bit to 12, if you like.

The frequency crush effect is also special: it uses an edge-softening algorithm a little bit like PurestDrive, for the purpose of turning the harsh and grating frequency crush you’d normally get from a plugin, into something a little more resonant, more sonorous. It’s still a sort of digital nasty, but steps way over in the direction of ‘classic sampler digital nasty’, again in a way that suits the more chill lo-fi genres. If you’re looking to have it be as clean as possible, take your audio and explore in the very lowest settings of the frequency control for a spot that’s minimally intrusive, or a digital-sampler overtone that works best with the sounds you’re using. All the stuff near 0 ought to be well behaved. Then as you crank it up, you’ll get rowdier digital artifacts, but always with that softening that helps lo-fi hiphop provide a soothing backdrop to life: which is partly due to the absence of super-extended frequencies grabbing your attention.

It’s both an art and a science, and Pockey is there to help you find the art through me digging into the science of how these things are done :)
