PunchyDeluxe

TL;DW: PunchyDeluxe is a smoother form of PointyDeluxe.

As demonstrated when demoing Echojam: when I couldn’t use a real guitar DI or amp, I reached for an unreleased plugin. PunchyDeluxe is basically just like PointyDeluxe, except there’s just a little bitty difference.

Instead of the fairly simple, efficient clipping algorithm in PointyDeluxe… PunchyDeluxe uses Longhand. The FULL Longhand, calculated in long double… but then with my ‘derivative BIP’ aliasing manipulation code, the stuff that causes high frequency artifacts not to come forward. Used on what’s basically a turbocharged sin() function already, which already doesn’t generate high frequency artifacts much.

If you’re not familiar with PointyDeluxe, apologies. Even I find this one awkward to use. PointyGuitar is better behaved, but PointyDeluxe needs you to keep the sliders pretty close to each other: any striking jump in settings might produce a crazy resonant boost. It’s very fussy. But it gives you a granularity you can’t get with the more approachable plugin… and PunchyDeluxe gives you that with a totally different, wildly more expensive in CPU saturation algorithm.

PunchyDeluxe also doesn’t have the speaker simulation built into PointyGuitar, but that’s available in Cabs2, or as the highpass and lowpass in ConsoleX2 and ConsoleX3. However, you might find use for it without cabinet simulation, in case you want wild pungent saturations on something that isn’t even a guitar: as always, there’s no such thing as misusing this stuff, it’s only about whether it works for you. It’s possible PunchyDeluxe is too CPU-expensive to work for you, but you can have it anyhow :)

Echojam

TL;DW: Echojam is an echo effect that is secretly a reverb.

Echojam.zip (575k) standalone(AU, VST2)
Echojam in Airwindows Consolidated under ‘Ambience’ (CLAP, AU, VST3, LV2)

This doesn’t have to be the guitar effect, but it totally can be!

The idea is, do an echo effect like in many Pink Floyd, U2 etc etc. records, but instead of using a delay, use a strange failed reverb that gathers all the early delays into a single clump, like a slapback echo. This is because I started getting strange failed reverbs that were trying to be single echoes but blurring them. Rather than immediately fix it, I thought ‘what if this could be echojam?’

And it totally can.

If you use a lot of regeneration, it will absolutely turn into a reverb wash. If you pick certain Select options (there are 17) you’ll get a wild stereo effect, but it’s no simple ping-pong. What you get is a scattering of 256 individual echoes not really lining up, not doing anything specific in stereo, but often doing very striking things in stereo.

There is basically no proper speed control so that can’t be adjusted. There is a speed control, but it’s sample-locked Bezier undersampling, so it’s got an okay tone (still a little odd when very undersampled) but there are only so many positions you can use. Not only that, there is no adjustment for sample rate this time, so you’ll be setting it based on your sample rate meaning if you’re at 96k (or 192k!) you’ll have more speed options because they are subdivisions of the native sample rate. If you’re at 44.1k you probably still have working echojam times on tap.

Not only that, all the options have faintly different delay times because it works off the strange failed reverbs, not by design. So you have to echojam based on what you hear, because there’s no specified tempo or even specific tempo: it’s always some form of blur! A little like SoftClock, but in the form of an echojam.

But if you can get it to gel, you’ve got a very lush spacey echojam that really fills up the space with detail, stereo event, and spatiality totally beyond a simple delay no matter how nice its texture is. And of course you can use it as a slapback (especially if you’re at high sample rate and it can run real fast) or as a slow dark messy echo on something less rhythmic. You can even get it to do the trick where it makes a big roaring swoop up to a rhythmic sound at the (approximate) delay rate, and you’ll be hard pressed to find a better choice for that… assuming you can get it to the right delay speed, or alternately tune your rhythmic thing until it matches Echojam.

Echojam ought to be a lot of fun for those who know. And now you know :)

VerbSevens

TL;DW: VerbSevens is a calibrated reference reverb plugin for reverb matrices.

VerbSevens.zip (619k) standalone(AU, VST2)
VerbSevens in Airwindows Consolidated under ‘Reverb’ (CLAP, AU, VST3, LV2)

Here’s a tool I use often, updated to keep pace with where my development’s been heading. (also, a person brought up something happening with VerbSixes that I could make better, but I doubt he expected THIS much better)

For years now, I’ve been developing reverbs along specific lines. I’ve never been a fan of allpass filters, unless they’re MV (my take on a classic bloom effect that’s made only out of allpass filters). I think they’re smeary and don’t actually sound deep, just blurred. I want to be able to make reverbs out of only comb filters, out of only delays, because that’s what real reverbs are made of: you just can’t have that many echoes, so people do their allpasses and other things to approximate the sound.

But what if you could have that many echoes?

A classic way to build up echo density is with a Householder matrix. It’s 4×4 so you need sixteen delays, but you get 256 echoes from just those sixteen delays, and better still, you can run them all either directly or inverted with no other gain changes. You get a matrix where if you feed the output back into the input, it gives you infinite sustain without any frequency running away. And feedback multiplies the echoes more, so it can get super dense for you.

But what about other matrixes? Turns out there’s math for Householder matrices of all sizes. If you use 25 delays, you can make a 5×5 matrix, where some of the mixing paths are times 3 and some are times negative 2. That gives you 3125 echoes before feedback, which is a lot more. On the other hand, some of your reverb paths are louder than the others, but only somewhat. Then there’s a 6×6 Householder matrix. There’s math for it, but now the diagonal path is twice as loud as the other paths, undermining the effectiveness… but now you have 46,656 distinct echoes. Before feedback. What could be better than that? (and this can be heard in VerbSixes, by the way)

Enter the Conference Matrix. It’s a 6×6 matrix, and unlike the previous ones, it leaves out one summing path for each section. It’s as if the diagonal path is zero: only five of the delay chains connect to the next stage. But it’s always a different section being left out, so all the information does find its way through… and the big difference is, now all the paths are unity gain again, just with some of them phase-flipped in the manner of a 4×4 Householder matrix.

When you combine one of those 6x6es with a Householder 4×4 to feed it, you’re looking at close to 12 MILLION echoes before feedback… and the regeneration can be infinite without it running away. But VerbSevens is primarily designed to be a test-bed: feed any combination of delays into it and it’ll show you what that does. It just happens to do double duty, as a sort of ginormous reverb pad. How does it sound when it’s doing 12 million echoes over an enormous space?

It sounds very nice. Because of the combination of the 4×4 and 6×6 I selected for it when you’re not compiling it to test things, it works like VerbSixes did, VerbSixes had a few little tweaks intended to produce realistic deep-reverb sounds, though, and they could interact with certain tones in a way that made a noise. VerbSevens no longer tries to do anything of the sort… so it’s a huge reverb, but also an unrealistic one, in that the highs don’t die away or alter. It’s just giant creamy space, turning any noise no matter how percussive into a total wash, and it now does that a lot better than VerbSixes ever could.

Hope you like the new genre ‘reverb and more reverb’, because this is your plugin for making it :)

DeRez5

TL;DW: DeRez5 adds new forms of derezzing.

DeRez5.zip (527k) standalone(AU, VST2)
DeRez5 in Airwindows Consolidated under ‘Lo-Fi’ (CLAP, AU, VST3, LV2)

Interestingly, the last time I worked on DeRez I was also putting a lot of time into Meter. Maybe I turn to imaginary digital noises when struggling to unearth the secrets of the great analog noises.

DeRez5 builds on everything DeRez4 can do: in fact if you set Square to 0 and Trim to 1, you have DeRez4 again, complete with the frequency crush, linear point-to-point interpolation, and Bezier filters to turn any corners into neat little rounded places without altering the straight parts of the lines. That is of course weird and has nothing to do with musical or harmonic behavior, but we’re doing something different so it doesn’t matter :)

Add the Square control, and now we can go from the original point-to-point undersampling behavior, to full zero-order-hold behavior: meaning, squarewaves! The control progressively untilts the angles of the point to point waves until they’re fully square in all their cornery glory. You can still use the Bright control to add neat little round parts to where the corners are.

The Trim control sounds innocent, but it’s anything but. If you’re heavily derezzed, and you increase Trim, it’ll sound like you’re raising the DeRez control back up again… kinda. Except it’s grungier, weirder, less predictable, and it stops imposing a clashing note onto the sound, because the frequency’s less regular. What it is doing is allowing angle-reversals in the underlying sound to determine the derez frequency… so if you crank it, you can definitely get more highs in there and save deeper crunchiness for when bass is happening, but it goes beyond that. You can sneak Trim up just enough to interfere with the steadiness of the underlying derez frequency, producing an altered sound with a little more ‘mulch’ to it but without dragging in as many highs. You can crank it and see at what point DeRez starts to step on the real highs. You can shape all that with Bright and Bassis, and heighten the edge with Square. And you should tune all this to the sounds you’re working with, because more than any other DeRez, the whole sound of this plugin interacts with the sound that’s, in theory, being destroyed.

Hope you enjoy melding this weird thing with your tracks! :)
