Cytomic "The Drop" Resonant Filter

[andy-cytomic]

Juce 8.0.1 has changed the way drawing on Windows happens, and now uses Direct2D instead of the inbuilt software renderer. I couldn't see any options to stay using the old method, so sorry for the issues.

I found a bug in this version (was not there before). Resizing in Live 12 is not possible for me. The GUI freezes, and I need to force quit Live via task manager. It works fine in Reaper though.
Setup: Windows 10 Pro Version 10.0.19045 Build 19045; AMD Ryzen 7 3700U with Radeon Vega Mobile Gfx, 2300 MHz; 16 GB RAM

Thanks for finding this issue. Can you please email support@cytomic.com so I can ask further questions?

Not used either this or The Scream for a while so had to reauthorise both, quite lucky as The Scream rendered the authorisation login screen correctly whereas The Drop looked like this:

...

(Using the layout of The Scream authorisation screen I could 'blindly' find the two required fields to fill in and authorise The Drop!)

This was in Windows 11 and using Reaper

Thanks for finding this issue. Can you please email support@cytomic.com so I can ask further questions?

If anyone has issues with the latest build, please email support@cytomic.com as email is a better way for me to keep track of issues and provide support. Feel free to also post an image or video here on a forum, and to report news of the outcome of support, but this is not the appropriate place to conduct support.

The Drop V1.8.8 (24 Aug 2024) is out:
https://cytomic.com/drop
* Fix: workaround for bug in Juce 8 D2D crashing when drag resizing on Win
* Fix: using non-bold font on menus for improved readability on non-HiPDI monitors

The Drop V1.8.9 (26 Aug 2024) is out:
https://cytomic.com/drop
* Fix: User Interface scale now recalls correctly between closing and re-opening the user interface, from the song state, and from the global default.

The Drop V1.8.10 (19 Sep 2024) is out:
https://cytomic.com/drop

Hello, please forgive my post hijacking. Me and a friend have been trying to contact you through both support email and the Cytomic Facebook page for a while, but without success, thus far. It's quite important (to me) in regards to your plugin product, so please kindly take a look in your inbox, sir.

I also never received replies to my emails. I sent two emails a few weeks apart from each other, IIRC. That was a few months ago.

I've been busy doing R&D so have only handled urgent support requests. All other support requests for things like license transfers (which I think is what you are referring to) are now replied to, so please check your emails.

Will you add the VCV filters to this in the future, as well as the clean SVF one like in Ableton? Those VCV filters are state of the art.

Also, what is the use case for the "Clean SVF"? Do you want a filter with lower CPU?

What I meant was a clean low cpu digital mode like Ableton's. Sometimes the non linearity is not needed, and yes I can just pull up a clean eq plugin but adding it here is just more convenient and I might want a clean highpass but an analog lowpass for example.

The Drop is all about detailed analog models with characterful non-linearities. Having a filter without non-linearities would mean that the filter is the only one in the entire set of 10 that would behave completely differently when comparing between circuits. A linear filter cannot self oscillate without infinite growth to the self oscillating resonance amplitude and no matter the input signal level there is no change in sound apart from the equivalent increase in output signal level. The clean filters would not only need a very clear way to differentiate it from the others, but also features like the Drive knob, > 100% resonance, and resonance trim knobs all would need to be disabled as they wouldn't do anything.

The easiest workaround right now is to use a low cpu filter to begin with, say the KSM, and switch off HD mode for it, and then adjust the input pad to -12 dB (which boost the output by +12 dB), and then adjust the pre to -12 dB and post to 0 to +12 dB. Switch off the Boost button, and use the Drive knob on the filter you want to have drive. This leads to the loudest harmonic of around -80 dBFS, so a sine wave at 0dBFS has a very subtle -80 dBFS amount of drive added. If you are using drive on the other filter you will not hear this drive on the "clean" filter.

So a completely linear filter is not really an option for The Drop. One option could be to have both an SVF and an SKF with only a single resonance non-linearity and an input op-amp soft-clip non-linearity (other filters in The Drop have a minimum of 6 non-linearities). Then at least then the drive knob, and the > 100% resonance knob, and resonance trim knobs would do something, but only if you want them to. If you kept the resonance at 0%, and didn't send in loud signals then I could construct the filters to have a completely clean sound with no drive added. As soon as you increase the resonance then you would again need to adjust the gain staging as listed above. Does that sort of filter sound useful?

I see, I forgot about the fact that the GUI would also need to adapt to the clean mode. That's too much work for a one man request, I'll stick with the low gain staging MD mode method. Unrelated but what have you been up to? It's been a minute.
