Awesome re:AUM parameters. Loving these filters. iOS Modular FTW!
nice set, thanks for the opportunity to try these out !
Little demo of the great sound of the JAF Collection. Even if using the filter “fully open” it can really warm up the sound with the various features like drive and tube and/or tape saturation.
Thanks for doing a video. Sounds good on your synth - I think it sounds even better on drums!
Wow how did you get yours black! Mine is grey ...i need that black
Probably the light slider lol
😄That’s part two: The Light Side and the Dark Side. Plus, I didn’t even get into the oscillator and modulations. Love that crazy comb filter.
Thanks! Gotta try on sum drums! 🥁
Did someone ask for drums? 😊 DrumPerfect Pro playing the same beat the whole video, though you might not have guessed. (This and the other video recorded in screen capture, so in mono. Don’t think that makes a difference in sound here)
Nice drums haulin!
I was putting some Blocs Wave drums through JAF Collection the other day and the sound was amazing.
I suspect the Blocs people had already filtered and massaged the drum sound to make it punchy, but adding the JAF Collection filters really took it to a new level (pun intended).
Thanks! Gotta try Blocs with it. Here’s another demo, with some 808 sounding drums in DrumPerfect Pro.
I bought the app and AM SO HAPPY TO SUPPORT THIS DEVELOPERS AWESOME WORK!
Hi haulin_notes,
thank you very much for posting this!!!
I discovered in your videos, that some filters will run into NAN state with extreme modulation. That’s a nasty problem, for sure. If that happens, it often can be eliminated (for the moment) by just switching the filter off and on again, as this effectively resets the internal states of everything.
The Just A Filter (JAF) filters are all somewhat “hairy” and raw and extreme. The entire architecture was designed that in mind. And sometimes the modules behave quite unexpectedly. This is just the character of that entire beast. (So if someone is looking for “scientific” filters, we highly recommend to use something different. ^^ ) Although we will try to fix the nasty NAN issues as much as even possible. But we definitively want to keep the “willful soul” of the entire product with its lovely internal quirks and do not want to try to “iron everything smoothly” ...
There is much (hidden) power in the additional modules too, as you’ve discovered. Even the latest addition, FSHIFT (a Bode-alike frequency shifter) inside the modulator has allot of potential for unusual sound manipulations. I am glad, that you discovered this!
Sometimes, while developing and testing, we find ourself lost in the depth of the beasties sound for hours, because it surprises us always new with unexpected crazy behaviors, things that just cannot be explained or controlled.
Some quirks with the UI will be eliminated with the next update, which is on the way. The AUM parameter issue will be fixed too, of course. We will try to additionally implement a more “common” comb filter too and possibly slightly readjust the extreme differences in loudness a bit.
The sound issues (NAN = not a number floating point issues) really show, that we indeed designed 30 completely different filters with the JAF Collection. Filters that were developed over an entire decade for different purposes. Each of the filters has completely unique design, it’s not just one filter base code and some different coefficient adjusting ... Therefore these quite big differences in loudness and nonlinearity. Analog filter design is a difficult challenge and has much to do with manual tweaking, rather than with science or correct math, and mostly a small change of a single coefficient can have deep impact to the sound or makes the filter running crazy or out of order.

👍Thanks for the detailed reply! That helps explain a lot. (Glad you like the videos. As long as I’m jamming with JAF, might as well record a video of it.) Thanks for the wonderful app, and the other free apps too. The JAF Collection has a warm and alive sound.
If you make another comb filter, please consider also keeping the current one as well. I’ve not heard another like that, and i think it is most useful. Also, if you aren’t already considering it, what about the possibility of a dry/wet level knob? (Or am I just not seeing it?) And not to be too greedy and impatient 😄, but the other thread mentioned a potential “dual mode” (two filters in series) feature that might eventually be implemented? Any comments on that?
Thanks again, and keep up the great work! 😊
edit: other thread about JAF Collection:

The JAF Dual Pro will be a separate product. It is far too complex, that it could be implemented or added into the existing. I’ve told about the Dual Pro in an earlier post here and explained why there are no band pass and / or band stop filters in the JAF Collection. (We also successively need more sold products, because we surely cannot live with only one, extending it and maintain it for a lifetime. Its currently even totally unclear, whether the development costs of the JAF Collection will ever become compensated.)
We will keep the current “Comb” as it is, of course, there are 2 free slots at the end of the wheel, that can be extended with one or two different models. The pass thru is still available at position 3.
The only essential extension that I can imagine now for the JAF Collection, is an “exchangeable filter drive” stage. Possibly also some other special signal modifiers after the filter. Some filters have the drive directly build into the filter (i.e prior for the feedback loop), some others not. A filter drastically can change its timbre, if the filter (saturation) model changes. So filter and filter drive are kind of symbionts that can produce new lifeforms. ^^
Dry/Wet would be somewhat strange with a filter, I think.
Good news, cheers!
That JAF Dual Pro sounds like it’s going to be one bad mofo with lotsa mojo! 😄 Looking forward to it. Til then using multiple instances of JAF will be more than enough. Glad to hear that the existing comb will stay, perhaps to be joined by another. The “exchangeable filter drive” should be cool as well, and add to the “extra features” already there. About the dry/wet, it was just an idea that popped into my head while using it. Not strictly necessary, of course. Might be useful in some instances. The Moog Filtatron app has a “mix” knob, I believe.
Thanks again. Boogie on! 💃🕺🏻
