Here's the first word..

Two filters in one box - nice arrangement, I think.

This is a picture of the only existing prototype which now isn't even in my possession - could only loan it out yesterday as the 1st production batch is underway already!

Main thrust was SERIES filtering where the Highpass out of the first State-Variable Filter feeds the input of the 2nd SV-Filter. Thus you get a MID-band from the 2nd filter's Lowpass output.

Block diagram will hopefully clarify!

Hot damn, ready already grin
BugBrand


Hopefully this block diagram can help explain somewhat.

Input Preamp - clean with gain up to 20dB

Two independent or chained 12dB/Oct State Variable Filters with resonance (Q) to self-oscillation.
Each filter covers the full audio spectrum 20-20kHz and has Low/Band/High-pass outputs though not all of these are accessible on the standalone module (there is a 1FW expander for modular users which presents ALL + extra CV and audio ins)

The filters can be run in Series or Parallel:
Series - the High output of Filt1 feeds the input of Filt2.
Parallel - both filters get the buffered input signal. In this mode the first filter is purely a Low-Pass, while the 2nd has separate Low/High outputs.
I was initially just going to have Series but it proved easy to add the mode switch.

The Filters are, of course, voltage controlled, scaled to 1V/Oct (haven't confirmed tracking range - imagine 5+ octaves tight tracking) - each one has an FM input (banana) and polarizing depth control. The Int/Ext switches are a weird bonus -> I took the BandPass output from each filter and that feeds the Int switch position for some audio cross-modulation - it can get very gnarly and chaotic, especially with high resonance.

The three outputs bands each have a polarity switch (centre-off for quick signal muting) so you can experiment with phase inversion/cancelling before an output level control and buffer.
The Low and Mid outputs are normalised to the High section so if nothing is plugged into either then the signal flows on to mix at High.

I found this quite powerful - you can either mix in mono from the High output, adjusting the different bands OR perhaps take each output to a different mixer channel & try panning (headphone space out). I'd been keen to start bringing some more stereo action to my setups and while this is obviously just MONO in, the 3 outputs gives some new fun powers.

Release date & price TBC - as mentioned, production is underway, but this always takes some time.
BugBrand
PS - here's an old recording during proto-times. Good on headphones for head-spin panning.

Any indication on pricing yet Tom?
BugBrand
Probably a nudge above the PT Delay but below the DRM1.
Gringo Starr
Is there any chance in the future that you will do a run of these that are designed to flow easier with Bugbrand modular systems? Banana-fied and uncased basically?

Btw, no offense to your vision and creation. I'm always a bit hesitant to ask things like this to the designers. I feel like that would be like someone hearing my song and saying "any chance in the future that you'll change the chord progression of the verse?".
BugBrand
The 1FW Expander will open things up for modular users and won't be available as Standalone as I don't have 4FW cases.

The expander gives individual filter inputs (designed for standard +/-5V audio signals as in the modular), individual Low/Band/High-pass responses for each filter, and a 1V/Oct CV input for each filter.

Pics once I've built the first one.

You know I've had to make a choice to move from the previous modular work, but I'm also generally trying to design in expansion possibilities to new designs.

Edit - to clarify - I will not be doing these new designs with bananas instead of 1/4" jacks. The work flow for me is more studio based rather than pure modular. Audio routing on jacks and modulation on banana. (yeah, don't say Buchlalala)

So, if I am setting this to parallel MID and LOW are both LP outputs from two different (but identical) filters?
BugBrand
Yup - may be useful in some instances - it was a simple addition so I figured to go with it - useful too with the Expander panel.

One thing I played with recently was using the Parallel mode with LOW going to centre, then MID and HIGH being panned (hard panned or less so). As you sweep the Cutoff2 the pan position will alter --- interesting to me is how you can pretty much maintain the percieved fidelity of the full audio band, while sending it into stereo weirdyness. (though wondering how vinyl mastering engineers will take all this...)

Don't get me wrong - I quite like the design! thumbs up
BugBrand
Here's the Expander.
Super simple - passive - just connects to headers on the main module.

In essence you then have two completely independent SV-Filters.
You could, for example, patch up a 24dB/Oct LowPass or HighPass (must try this actually!) - just use in parallel mode.

Truly a beautiful set of demos, Tom. Very nice. Can't wait!

Thanks!

One more while I was testing boxes.. I've already been using the little MiniBrute for checking the 1V/Oct tuning of the filters, but I thought I'd try 'ping-ing' the filters with the keyboard's Gate output - I used to do that with the modular (PRC3A SV-Filter). Works quite nicely (though would prefer Trigger rather than Gate)

Completely OT, but inspired by your ping demo above, Tom, I did this little noodle as a little night excercise, all bug modular, based on gate-pinged SV filters:

Fucking fucking fuck is this good!

I never considered flipping the phase on opposite sides of a filter before. The frequency canceling (along with the fucked up internal modulation) is blowing my mind.

Gotta say that I dig the CO Filter for live drone tweaking. The big knobs are great and am running into two channels of a mixer for theoretical hard panning.

Here's a lengthy slow build jam (action starts around 10 min) with the 2x CO Filters processing 6 drone oscillators each out of a NLC CMOSC. Headphones are recommended as the DRM1 bass is low...

Thanks!

In #1 the drone part was actually the 12 oscillators from the CMOSC (6 pairs). There are other "voices" in there from the VCO panel. In #2, I had to leave out the Reds because for the performance I was preparing for I ran out of table space to fit an 11FW enclosure and Bug PSU (another plus for the smaller red enclosures). Currently, I'm working on a new setup so I can fit 2x PEQs, 2 COFilters+exp, and 1 or 2 PT Delays.

The two sets of 3 pairs were mixed into the two Mix modules of the NLC VCO panel with the output of each Mix into it's own COFilter. The High (mix) outputs of the COFilter were run into a little Soundcraft mixer. With the two freq knobs and the level knobs, it's really easy to blend and evolve the sound over time. This is a pretty simple and naive usage of the CoFilter but it's an application that really sold me on the design of the Reds in general as both studio and live tools that can be add-on to any other system. I enjoy using the COFilter and PEQ more than a typical outboard/mixer EQ for creative purposes and am not really into tweaking DAW plugins (the pain!).

In general, I find myself using the Reds more to enhance other systems as a "modular sidecar" rather than keeping it with my Blues. For example, they are an amazing complement to NLC, Ciat-Lonbarde or even Buchla stuff. Combined with an Easel/208r or CQ/PB combo, those systems would really open up a lot of sonic possibilities beyond their typical sound. I don't really patch them as much with Serge or Bugbrand (except DRM1) which is opposite of what I thought when I got them!

Thanks for the run-down! Always interesting to hear how people are using these tools. Would also love to hear it if you got some more of these drones.

So.. now that I've begun releasing a 2nd run of the CrossOverFilter, do any users care to comment on how they've found it? It has been out roughly a year now.

I'm partly asking because it seems to be a slow-burner - the PEQ seems to get the attention at the moment, so I wonder if I haven't described the POWER clearly enough?!

One point being - someone said a couple of days ago that they'd rather wait for a PEQ because they wanted the big-knobs for High-pass & Low-pass.. Well, I said...
- if you take the MID output, then you get that WITH EXTRAS (resonance and CV control, for example) -- the first filter does the High-Pass, the 2nd does the Low-Pass. (MS20-ish even perhaps?)

But then.. you can also mix in a bit of the extracted bands at the same time - or play with the phasing (definitely changes the resonance response) - or do those with the individual outputs and get crazy with panning.

The 3 outputs and/or the normalised output mixing = (I feel) pretty darn powerful! You can, for example, get phasing effects if you keep both levels up around the cutoff point ( x 2 because there are the 2 filters). Hell, it even gives 2 pure sine-waves with the ability to self-modulate (Modulation set to Int - this takes each BP filter output over to the CV input)
Zeitdehner
Maybe I'm misunderstanding something, but isn't it a bit awkward to have the mute in the center position of the polarity switches ?
I think I'd rather be able to switch polarity without having to get past the mute either way... hmmm.....
BugBrand
I don't *think* it is too awkward - but perhaps others can comment..
- in testing I switch from +ve to -ve, usually finding that it moves instantly through the centre-off position.
- saying that, I've never really played with the polarity switching in a live situation.
indexofmetals
The PEQ is great (I have 6) and use them with 500 series preamps & compressors. I've got a Chandler Curve Bender as well and JLM 500 series EQ's and the PEQ sits at least equal to them.

but I still think the COF is better. I use it and the wavefolder in every patch. I've gotten to know it so well that I wouldn't change anything.

Re phasing, the basis of this song were two Bugbrand patches that I made as close to each other as possible, done live as stereo (both fed into pair of Roland tape echo's as didn't have a spring tanker at the time) and I was manipulating both COF's by hand so the sweeping isn't perfectly in sync.

I was just wondering...perhaps I'll try this at Phisynth's one of these days...

@Indexofmetals : that track sounds superb woah thumbs up
vegas7188
I think when i got a PEQ my intention was to use it as part of a traditional channel strip for recording and mixing duties and i looked at the Crossover filter and kind of thought of it more as a part of a synth setup (at the time i didnt get one as i felt i already had filters in my synth setup). As i read on and looked into it more, the more into the idea of the Crossover i became (how it can essentially function in a similar way as the PEQ in a Channel strip set up if you want plus alot more) and now i bought one on this run! Hooray!

I also thought i might try it wth my bass guitar going via the crossover to a couple of amps (hi-pass to guitar amp via other effects perhaps) and low-pass to bass amp perhaps clean keep some of the low end in tact and not blow up guitar amp. Could be quite fun.

Plus obviously big bonus is banana cv ins.
/\/\/\/
The PEQ is great at what it does - the physical layout is perfect and it's a very useful tool. For me, the COFilter is much more fun to play with, and playing with resonance and self-modulation leads to more interesting results compared to straight EQ changes. You can pull little hidden melodies out of a drum loop or completely change the character of a sound - almost like some kind of sonic alchemy. (With the addition of a few other guitar pedals, I've made an sk-1 rhythm preset sound like a fairly convincing symphony orchestra, and a very drunken marching band.) When generating a sine wave with each filter, you can play some nice overtone series drones. And the stereo applications are great too... so many directions to go within this box.

I would be interested to hear any creative uses for multiple COFilters... I'm definitely considering picking up a second one.

Moving atm to another place, but I was able to test for the first time the COF filter during 10 mins.
I must say: I was very impressed! To me, I'd say a true revelation.
What Tom did here is IMO quite unique! we're not worthy

And I'm impatient to be able to play again with the BugBrand system It's peanut butter jelly time!

Hey just got my first Bug gear, a CO Filter and PEQ a few hours ago and as expected they are totally off the hook! Really exciting to have these two unique tone shapers in the studio AND they look and feel so freaking awesome, I love red!!

Here is my first play around on the CO filter. No stereo freakery yet.. Running into it is the Little Deformer...another magnificent piece scored a little over a month ago and Im just running through a buncha patterns I made while tweaking the CO thumbs up

Finally I took a few mins today to check the CrossOver Filter functionality. Really a great design!

Had fun at the end of the session with playing it simply in self-oscillating mode. Same CV from sequencer going into CV from 1 & 2.
Direct Out to reverb/delay.
Sorry, I should cut at 1:00, but I'm on the other computer now without possibility to do so before upload.

We don't hear always the highest note, cause I mute CV2 from time to time.
I like how the highest note from 2 sounds when Q is not fully opened (VCA/LPG alike):

So... someone has got to be using one of these as a phaser?? Flip polarity on one or two bands and modulate the cutoff?

Haven't got one but after reading - seemed an obvious application for a neat unit!
BugBrand
Kind of -- I've not been playing with the phase switches much still, but asimple application I've been using is to keep all three bands turned up about the same, then modulate cutoffs and have a bit of resonance. It isn't really phasing as such, but gives lovely resonant swirly additions!

I've only just got the studio re-jig roughly to a point to play - I should now get on with taking the different band outputs and feeding them to different post-processors - daresay phase switches could be extra useful there.
Paranormal Patroler
So after an email exchange with Tom and some fair time studying the schematic is seems that in order to use the extra inputs of the COF you'd need extra preamps to match the required modular levels. In addition to that the BP outputs from the original design (not the expansion part) don't seem to be leading anywhere, so I'm curious, what is exactly output at the BP? Obviously it's a band at the Cutoff frequency of each filter, but is it's size controlled by the Q ? If not, what are their purpose in either Serial or Parallel use?

As per the schematic they're never used (I might be reading this the wrong way) and since there is one frequency knob per filter I'd like to know how the BP band is determined.

Also, does the internal normalization (LP > BP > HP) apply for the expanders as well?

Obviously I'm looking to get on COF and use it in stereo, using the parallel functionality, but it seems one is forced to buy two COF for that purpose. hihi

I don't have an official expander but theoretically mine should work the same ...

The COFilter expansion ins/outs work fine at line level. The BP output is exactly what you would think and the Q knob changes the Q. Without an expander the BP output is only available a mod source. There is no normalization with an expander it's just allows you to use the 2 filters inside the COFilter as 2 independent filters.

I'd love a stereo COFilter and have mentioned it here but think running 2 in quasi stereo would be a soup sandwich.
BugBrand
There are two 12dB State Variable filters - standard fair in my work - always with Low/Band/High outputs possible.

As soup notes, the BP is fed to self-modulate the Cutoff.

I termed the unit sections Low/Mid/High to differentiate from the State Variable terminology (Low/Band/High-pass).

In serial mode, first filter gives Low-pass output and passes on to 2nd filter.
2nd filter gives Mid band (highpass in first filter, lowpass in 2nd) and High band.

In parallel mode, first filter again gives Lowpass. 2nd filter gives LowPass (instead of Mid) and HighPass.

The unit has a simple/standard preamp to bring external signals up to typical modular levels (+/-5V). The expander offers a direct input to the filter stages, along with direct outputs and an extra CV input per filter. You should generally then switch the mode to Parallel (so the filters are completely independent)
Paranormal Patroler
Thank you Tom and soup. I understand how the Mid band is created in Series. I'm just not sure how the BP is defined when the two filters work in parallel, since each one has only one cutoff control. Does that specific value define the band and thus each BP is of a fixed width? I mean, there's no way to change the size of the BP when the filters work in parallel, right?

I would personally love to have the band outputs and be able to cut a stereo signal in three distinct sections and have them fed to other devices. I tried my best to see if this version of the COF would do this but it seems having stereo requirements is trying to make the design into something that it isn't. I will add my voice to the choir, I'd love to see a stereo version of this with common control. Maybe something to look forward to after the stereo PEQ ?

Oh, that's neat!
Like the switching (On/On/On, right?) & the extra jack outputs.
The jack inputs is neat too - though you'd maybe have to watch resonance levels if the input signal isn't up around +/-5V amplitudes.

The switches are on/on/on. The jacks are intended as an octatrack interface so there's not much intentional self resonating but I've used a lot of modular filters with line level devices and yeah, it's pretty easy to blow your head. zombie

Just fascinated by the sound of newly acquired COFilter SlayerBadger! just had to hit the rec button of the phone. I need no fcking tube hihi


Sorry for phone mic recording. But, this sounds so vintage! Volca keys plays a simple chord progression seq (backing pattern). Volca is fed into Bugbrand Crossover filter then PTDelay. Filter 1 of COFilter is self-oscillated (sine wave generated) and sequenced a melody by SQ1 (top melody). Played on the Roland mobile cube. Volca's filter is wide open and no delay added, roland is flat as well. PTDelay sounds so vintage at some setting, boosted by COFilter.. Even though mobile cube is a small amp, with this setup it's so vintage sounding. oh you only have to listen it over here...
BugBrand
Aye - lovely sounds there!
chrisdermo
I picked one of these up yesterday - what a stunning sound! we're not worthy

The sine tones from self oscillation are particularly beautiful - so creamy and smooth, looking forward to playing them with a keyboard. I've had great fun this morning using a repeater electronics horndog and double knot to modulate both cutoff CVs with lowpass panned left, bandpass centred and highpass panned right, playing with the phase switches and parallel/series applause. This thing is seriously powerful and I've barely even got to sending an audio signal to it's input yet It's peanut butter jelly time!

No need for the expander - just shoot your gate straight into the input jack and adjust the gain as necessary for more or less of a 'tick'

Many many many many many Huge thankses to Tom for helping me achieve my dream filter system applause

That's looking so awesome! I want the expander for the filter (if it's obtainable) but am not sure how to prepare the casing then...

I'm not looking to open the floodgates making such custom setups, unfortunately - it was a one-off for Chris, partly helping me take a step along prototyping a new Dual Preamp.
The Expander (which is fully passive, just sockets on a panel) is available from me, though I don't push it - figuring how to mount it is really the issue as I don't have 4FW cases.
jimmie
Thank you Tom, yeah, with the expander I'd have problem for space even with an 11FW case so I'm holding the idea till you might someday come up with some other option - something 4FW perhaps (like LFOs for PTdelay/COfilter, then fit with 11FW hihi (but I want the expander before Dead Banana )
chrisdermo
A utility lfo module would be a dream. Or just a remake of the syn1 for hard sync'd oscillators to be used as clocks/modulation/audio sources. I'm dying to get my hands on a syn1 love think maybe a chirper will tide me over though.


Been having so much fun with the COF -

(Headphones for stereo action!)

Lots of other CoF featured clips on there too.

or maybe mixer (VC panner and VC send-return for PTdelay) hihi

Sounds so good Chris! I'm short of mixer inputs for separate outs waah

It's probably not recommended but ... it'd be simple to add bananas to the COFilter case and get all the functionality of an expander.

Man I had a vague idea about how this would sit with my other gear when mixing but it really blows my mind how versatile it is when processing a mono signal into stereo... now I wish I had two of these... Dead Banana

~sigh~ I know the feeling!

Back in stock. Kinda want another! Pinging these things is heaven, the tone is so woody it's like instant xylophone.

Not to mention their ability create wide and dynamic stereo fields from mono sources.
