Will anyone in Europe be stocking this soon? (no UK)

holy shit. holy shit. ordered.

EDIT: Look at the flow chart (block diagram). It is quite interesting, especially all the jumper options for routing. The PCBs + panel are only $100, so if you make your own panel you can add switches for all those routing options.

I noticed that. Even if you wanted the original panel (which I do... Love the graphics) you could add a small panel on the side with switches for quicker changes.

Overall I like the features. Gonna build one for sure.

Wow, I love it! Once I have time to build again I'll order the pcbs/panel. Looking forward to seeing the build docs, just so I know for sure what I'll be getting myself into.

This could be alternative for BastlxCasper's Dark Matter. At first look, I thought of it.

[skysaw]

This just looks so sweet, and seemingly an endless garden for creative inspiration.

The video is so well put together, too. If only all modules had such a clear presentation!

thank you! still working on the build docs, but getting closer. if youve built my other modules it shouldnt be too bad. and like i said earlier in the thread, it has a lot of resistor arrays which simplifies things. but just the sheer amount of soldering and assembly is part of what makes it more difficult.

but the f3db is made in a way (with pcb cards like the buchla 296) so you can technically swap out parts or pcbs for other frequencies for the bandpass filters since they are all the same circuit essentially. so 3 of the pcb cards are really similar in layout with many parts in the exact same place.

which i didnt mention but there will be an expander(in the future) for the f3db so you can chain 2 or 3 together to have a more spectrally complete filterbank. and the expander will have some additional features.

@gnsk
interesting i never looked at the flow chart for the dark matter until now. i know of the module, but dont think ive ever tried one. forgot it had eq and an envelope follower. they are similar although mine is more in the buchla filterbank vein, and with a lot more clipping and output options.

@skysaw
thanks, i appreciate that. yea i was just saying on reddit how she did an amazing job cleary and concisely explaining the module. and it's cool she brought some history into the demo.

[Kosmikos]

This is one of these modules I didn’t know I needed until I saw it.
Any idea if/when the kits are going to hit Thonk?

[djd_oz]

Has anyone created a Mouser project for this?

[xidnpnlss]

Thank you for your answers!

yea it can definitely do all the subtle, droney, and normal tame/clinical filterbank sounds. did you watch sarahs video?

Yes, but I wasn't clear with my original question, and that's my bad. My question is if it - with maybe some creative patching - do filter sweeps like a "normal filter". That is, can it open and close multiple bands with one cv source? I did watch both videos (both excellent btw) and did not see it so decided to check. I assume not - that's not it's purpose, obvs - but was just curious.

This is amazing, right here. I was looking forward to the Erica offering but the idea of making a custom chained version has my brain bubbling thinking about the possibilities! Fantastic.

[Exit Chamber]

I've never really got filter banks until watching the demo, now I need one in my life.

I would be keen to know this too.

I think the reisistor Mouser/Tayda product codes somehow grouped into "SKU: GROUP PRODUCT 1" in the BOM.

Code: Select all

it might be possible if you had a multi-phase lfo that scanned through the bands to give the illusion of changing the cutoff frequency of a "normal" synth filter. but i assume it wouldnt be very smooth(and wouldnt sound like a normal vcf) since some of the freqs have quite a bit of distance between them.

@kosmikos and exit chamber
not sure when thonk will get them. they are aware of the module and put in a small order for it, but unfortunately it couldnt make it into the recent order i sent them last month. i can send them an email.

i think exploding shed in germany will be the first to get them, maybe by mid/late this month.

@durdee
thank you, im glad!

@djd_oz
group product 1 is a tayda sku. it will take you to the page where you can order multiple values of 1% 1/4 watt resistors all on one page. i dont order resistors from mouser. so someone will have to figure out a mouser cart for those on their own.

o yea Brett Naucke's awesome demo of the f3db premiered over the weekend

[tl3ss]

Could use something like an Octasource since it has phased outputs, wouldn’t be smooth though

Cool, I don't mind waiting, will be patient

hmm ... Zlob VC F3DB is expandable like Entropy according to the website, I wonder what he had in mind ...

that's what he said earlier:

i guess the additional features could be switches for the jumper setting options mentioned in the signal chart (which would be awesome).

Unfortunately there was not space to accommodate breaking out all the jumper options to an expander easily. I don’t like the idea of having tons of 3pin wire jumpers which can introduce a lot of variables for something to go wrong or disconnect. I had to settle on one 16pin ribbon cable break out for the expander because of the space restrictions.

The expander hasn’t been designed yet. But some features I’m planning to include is summing of the envelope followers, additional decay control, and maybe some related gate outs. The idea was to also include the classic parametric scan and tilt features if possible. And the expander will of course sum the evens odds and all outs of the 2 or more filterbanks together. And maybe more stuff not sure yet.

I guess if there’s enough interest I can design a small break out switch module for all the 3pin jumpers.

Posted the build docs! Still working on the top pcb docs, those will be out in a couple days. Not like anyone has the kits or pcbs yet anyways. Modules and kits started going out Friday though.

Thanks a lot to everyone for the overwhelming response on this module. Still so much soldering to do...

[Phitar]

Have a kit on the way! Expected this Tuesday. Problem now is that since I just got moved into a new place I gotta find the box that has my soldering/workbench gear packed up in it. Probably in one of those boxes I can't get to.... on the bottom of the floor to ceiling stack in the back corner of the spare room with all the excess furniture stacked in front of it... betcha that's where it is!

This is something I would be interested in doing but could do that sort of thing easily myself in the future. Much more interested in seeing the final expander design as you envision it right now. So far it sounds great.

[skysaw]

Will this be kit only?

[gb2]

there's an assembled option too: https://zlobmodular.com/product/vc-f3db/

Thank goodness! When it comes to soldering, I feel like I’m working with eleven thumbs!

[ronnieb]

Any ideas when 3u are getting some?
