What is the last version of The Glue that works on Windows 7?

I've applied these to The Scream with excellent results, making it lower cpu and more robust than before. After another couple videos it's time to begin work on The Glue v2, very exciting! Thanks for hanging in there everyone.

What is this "symbolic simplification engine"?

All Cytomic core analog modelling DSP is handled by an automated symbolic circuit solver and optimised code generator that uses symbolic expressions throughout. This way expressions can be simplified by standard algebraic rules, which is essential to automate optimisations. For example

Code: Select all

a*b + a*c -> a*(b + c)

and you just saved one multiply. These simplifications, along with working out which bits can be pre-computed, add up to lots of savings on cpu. This makes it possible for Cytomic to do in depth and detailed circuit models but still be reasonable on the cpu.

The rabbit hole goes a lot deeper, but that gives you the general idea. For more info you can check out the technical papers section of the Cytomic web page, in particular there is an Audio Developer Conference (ADC) talk I gave linked at the top of the page called "From Circuit to Code: Under the Hood of Analog Modelling" -

Hi Andy C, I love the ableton glue compressor that you guys made. Is your “the glue” a step up from that? If so, is it correct that a v2 is imminent?

Thanks

The core DSP in the Live version is identical to that of the plugin version, but the plugin offers higher quality oversampling and a few other features the Live version does not, including peak needle mode, and automatic switching to higher oversampling rates on render. The upcoming Glue v2 will offer an HD version which will not be in Live, and will be a free update for those that currently bought The Glue without discount from Cytomic directly. I have no idea when The Glue v2 will be ready, so if you want the HD mode specifically then I recommend waiting until there is a release ready to try.

For The Glue v2 I'm building a kit version from DIY-RE so I can measure each component before soldering it together, which will save some time and guesswork later on in matching component values. I'll post progress along the way, so there will be plenty of news about when things are getting closer to release.

Will you add the Mono SC button from the DIYRE's?

No, I won't add that, but there will be a dual mono to stereo linked stepped knob to change how things operate. If you want to sum a stereo signal to mono, and then send that to the external sidechain input of The Glue you can reproduce the GYRAF version, which saved money by only having a single sidechain ratio shaper and amp. If you sum a stereo signal to mono then you can miss peaks due to phase cancellation, so it's not ideal for a compressor to behave this way.

Thanks for doing what you do, and so thoughtfully and thoroughly! Your stuff (from FXPansion to Ableton and Cytomic) has always stood out from the rest.

Reading about the solver was interesting, will have to check out the paper you linked.

So old and still so good

For anyone interested about news around The Glue v2 I've written an article about my last 3 months of work, and I'll post more articles in the future:

News: The Glue v1.7.8 is available for download

The Glue v1.7.8 (3 May 2025)
https://cytomic.com/product/glue
• New: added “read only” VuMeter parameter to report the main VU gain reduction needle position to AAX and VST3 DAWs that support metering

(edit: this version of gain reduction metering will enable Pro Tools and anything that can use VST3 "read only parameters" to display gain reduction metering, which includes SSL UC1)

GR metering does not appear in REAPER. It does work with Softube/Waves.

I support VST3 read only parameter meters, as well as AAX meters. If REAPER supports either of those then it will work fine. I'm pretty sure REAPER only supports the Presonus VST3 extensions for metering, which I have not implemented.
