bringing mojo back – volume 2

ThrillseekerVBL is an emulation of a vintage broadcast limiter design that follows the classic Variable-Mu design principles from the early 1950s. These tube-based devices were initially used to prevent audio overloads in broadcast transmission by managing sudden level changes in the audio signal. From today’s perspective, and compared to digital dynamic processors, they appear to be rather slow and can be considered more of a gain structure leveler. However, they still shine when it comes to gain riding in a very musical way – they’ve written warmth and mojo all over it.

ThrillseekerVBL is a modded version that not only features basic gain control, but also gives detailed access to both compression behavior and the characteristic of tube circuit saturation effects. Used in subtle doses, this provides the analog magic we so often miss when working in the digital domain while overdriving the circuit achieves much more drastic musical textures as a creative effect.

ThrillseekerVBL offers an incredibly authentic audio transformer simulation that models not only the typical low-frequency harmonic distortion, but also all the frequency- and load-dependent subtleties that occur in a transformer-coupled tube circuit and that contribute to the typical mojo we know and love from the analog classics.

new in version 2

Conceptually, the mkII version has been refined in that the peak limiting itself is no longer the main task but versatile and musically expressive gain control as well as a thrilling saturation experience. The saturation is now an integral part of the compression and is perfectly suited for processing transient-rich material. Both compression and saturation can be individually activated and controlled.

The circuit-related frequency loss in the highs has been almost eliminated and the brilliance control – originally intended just for compensation – can now also perform exciter-like tasks. The bias control has been extended to shape the harmonic spectrum in much greater detail by allowing the contribution of second order harmonics as well as the adjustment of the saturation behavior in the transient area of the signals. The transformer circuit has also been technically revised not only to resolve all the subtleties realistically but also to reproduce an overall tighter sound image.

ThrillseekerVBL has become a real tonebox, able to reproduce a wide range of tonalities. It provides access to the attack and release behavior and all compression controls can also affect the saturation of the signal, even when the compression function is turned off. This allows specific textures of signal saturation to be realized. As with the good old outboard devices, the desired sound colorations can be achieved just by controlling the working range. And if too much of a good thing is used, the DRY/WET control simply shifts down a gear.

To further improve the user experience some additional UI elements have been added giving more visual feedback. Although oversampling has been added, the actual cpu load was significantly reduced thanks to efficient algorithms and assembler code optimizations.

ThrillseekerVBL mkII will be released October 14th for Windows VST in 32 and 64bit as freeware.

What I like about the Behringer 2600

What I really like about the Behringer 2600 is that it’s not just a plain copy but introduces some real useful improvements over the original concept. Most important to me is the 19″ form factor which not only reduces the originals size and fits in the rack but also remains big enough to enjoy a great user experience while cabling and tweaking things. And they got rid of those speakers! Instead it offers 2 filter revisions to choose from, two of the oscillator sections are now fully featured, the LFO is part of the main chassis now and new additional timing options for the envelopes has been added as well.

On the other hand, the Behringer 2600 sticks to CV gate voltages following original levels which limits full integration in todays modular world quite a bit. However, this is currently not a big deal to me. I only wish they would have made a true analog delay instead of the spring reverb (emulation). Offering audio in, the device also doubles as an excellent analog effect unit which seems to be a little bit underrated in this regard. Given it’s pricepoint, this feature is already something to consider if one is just looking for an outboard analog filter box or an alternative for something like a MS-20.

sustaining trends in audio land, 2021 edition

Now, after spending some time on digging a little bit more deeper into the current offerings and market situation in audio production I just wanted to briefly outline some of my personal summaries regarding sustaining trends but maybe outline also some new things I do see on the horizon.

The mobile audio evolution

To me this indeed looks like an ongoing trend for years now which simply does not stop. On the one hand we can see the whole software and especially the App market continuing and increasing in all areas and platforms: notebooks, tablets, smartphones and their respective eco systems accordingly. Where Ableton once started in providing an almost complete mobile music production approach in literally just a bag, Bitwig and others followed and now Apps are everywhere allowing any kind of recording and music or media production on the go. Apples recent move with the M1 SOC (System on Chip) approach fits perfectly into this trend by increasing the mobility even further in terms of power, size and efficiency. Others will follow this path for sure. Also we can see traditional music gear manufacturers going more and more into compact and battery powered solutions as well, such as the Korg Volca series or the Roland boutique thingies, just to name the two.

The retro cult continues

Companies like Behringer will continue to spit out analog HW clones like there is no tomorrow. Whether thats synthesizer reissues or blatant plain copies of vintage mixing outboard or modeled software – you’ll find everything and in almost all shades of quality and price. And I think this is a really good thing to have such a variety to choose from and also this will lead to some serious price drops in the overpriced used gear market in that area.

Modular madness

I don’t think this is part of the overall retro trend but a niche on its very own. In any case the modular synthesis thing is still gaining more and more momentum. There is a sheer amount of hardware options to choose from and meanwhile also quite a lot of audio interfaces and controller solutions are offering not only Midi but also CV support. Even in software land one can put his/her virtual hands on something modular. All in all, this looks and sounds like real fun and a great opportunity to spend a lot of time on (and money).

Look mom no computer

All those neat outboard DAW-less setups shown on YT: Some hardware samplers and grooveboxes here, some fancy retro synths there and fx stomp boxes all over the place. Well, “Look mom no computer” is of course absolutely wrong here because half of that stuff has tiny little digital displays and computers underneath you have to tinker with. Personally, I would prefer some neat “one knob, one job” analog interfaces plus a real full-blown DAW any day. However, definately a sustaining trend and a good thing.

Loudness war, quo vadis?

While it seems that LUFS finally made it and in fact has been successfully settled as a standard in the broadcast domain – in music production in general it has not. Todays audio mastering target levels are still insane and even some “engineers” continue to present converter clipping as the holy loudness grail to their YT followers. That really hurts. At least some of the big streaming sevices restricted target loudness levels to -14 or -16LUFS which gives a little hope.

ITB production finally took over

Now that even the last renowned mixing engineer has finally surrendered to the dark side in the box – at least for the recording and mixing part – the question remains, why this has taken so long. Was it for quality concerns? The time-to-market pressure to finally have total recall in all regards? Simple ignorance or fear? We might not be sure about the final answer but we do know that today almost everybody can run some media production tasks in a decent quality on his very own while having a low entrance barrier. And this is what I really would call the “game changer” of the last decade. Now, your skills are the limit.

Game of DAWs

There is really no trend in particular here other than the fact that we have the very same players on the board since a decade ago. Maybe Bitwig will aim for the crown from Ableton? It’s whole inherent synthesis and modulation integration make this comprehensive sequencer an instrument on its very own and also it runs natively on Linux. All the other contenders improved step by step here and there but quite comparable. Maybe having build in mixing scenes and more convincing analog style summing is a thing which sticks a little bit out. So, on my own I wasn’t that much impressed about this very last episodes and now I’m looking forward to an upcoming but much more entertaining season, hopefully.

The pandemic impact

As we all know, the Covid impact on everything live performance related was and still is a sheer desaster. How this will evolve in the future is hard to predict but it is clear that there won’t be any back to normal any time soon if ever. That means this area must transform into the digital/virtual domain as well and most of the suppliers in exact this kind of areas are already the winners of the current situation.

Stay healthy!

tips & tricks with ThrillseekerVBL

The Sweet Spot

The plug-in includes a preset called “LA Sweet-Spot” and one can safely use this setting on almost everything just to add a little more mojo. Just drive the unit with a proper “IN GAIN” amount so that the overall compression and distortion fits to the source.

Increased Stereo Imaging

If ThrillseekerVBL is used on stereo program material, I would recommend to use the TRAFO option to have the most prominent stereo imaging effects. Also, if there is just a little gain reduction amount applied, I would prefer the “DUAL M” option opposed to “STEREO” linking. And I would always use the “DUAL M” option on sources like vocal groups, panned rhythm guitars and stuff.

VBL as a Mastering EQ

One common mastering trick to open up a rather flat/dull track is to dial in a slight but broad 5kHz boost with an analog tube equalizer. Due to the tube circuit also higher order harmonics are generated and the whole stereo image opens up.

This can be replicated perfectly with ThrillseekerVBL: Move the “BRILLIANCE” screw to its top most position and set the “AMP” knob to 0.68. If distortion is too much now, just back it off by dialing in some compression and/or lowering the input gain.

If the EQ effect amount is too much, simply use the “DRY:WET” option. Also make sure that the trafo is in and prepare yourself for pure awesomeness.

Some Shorties

• Avoid pumping: Dial in some more “EMPHASIS”.
• More HF focus: Turn the “BIAS” screw clock-wise.
• Upward compression style: Dial in some dry signal amounts (just a little).

released: ThrillseekerVBL – Vintage Broadcast Limiter

Bringing mojo back – Thrillseeker VBL is an emulation of a “vintage broadcast limiter” following the classic Variable-Mu design principles from the early 1950′s. They were used to prevent audio overshoots by managing sudden signals changes. From today’s perspective, and compared to brickwall limiters, they are rather slow and should be seen as more of a gain structure leveler, but they still are shining when it comes to perform gain riding in a very musical fashion – they have warmth and mojo written all over.

Thrillseeker VBL is a “modded” version, which not only has the classic gain reduction controls but also grants detailed access to the amount and appearance of harmonic tube amplifier distortion occurring in the analog tube circuit. Applied in subtle doses, this dials in that analog magic we often miss when working in the digital domain, but you can also overdrive the circuit to have more obvious but still musical sounding harmonic distortion (and according side-effects) for use as a creative effect.

On top, Thrillseeker VBL offers an incredibly authentic audio transformer simulation which not only models the typical low-end harmonic distortion but also all the frequency and load dependent subtleties occurring in a transformer coupled tube circuit, and which add up to that typical mojo we know from the analog classics. This would not have been possible with plain waveshaping techniques but has been realized with my innovative Stateful Saturation approach, making it possible to model circuits having a (short) sort of memory.

ThrillseekerVBL is a freeware VST audio plug-in for Windows x32 and you can download a copy in the Downloads section.
