OK - I HAVE GOOD NEWS!!!
1) Yes, the LPF is in there and will be in the next release
2) Jesse thinks he knows a way to offer more tuner options on input 2
BOTH OF THIS ITEMS WILL BE IN THE NEXT RELEASE.
We have been INSANELY busy with the Ultrawave which is a crazy-deep pedal. I am not exactly sure when the next release will come, but its weeks, not months. Sorry for the confusion. I need the weekend to start so I can catch up on work.
Thanks.
Project-based work is a crazy way to subject one's brain to information, but it's the work a lot of us choose — and for reasons that often make me question my sanity — actually prefer!@600 Ohms @NPappas

To be fair, you have 2 channels of 10 bands to play with. Currently, I'm using the lowest band on 1 channel as a Low Cut filter (HPF). It works, sure it's "only" -15db...not a sharper roll off, but it's good enough for 99% of speaker cone protection. That still leaves me another 19 bands to play with.
I started off doing that and migrated to using the variable HPF on my amp knowing that FOH will also have HPF applied, probably twice. Once in speaker processing and once at the board.
in my managed PA, the BSS Speaker processing has a 56db HPF at 40 as below that is the death zone for my old EAW LA400 subs. My boards all have master HPF on the main outs and also channel HPF. Pretty much all modern digital boards have it.
I can also apply it in my DAW. So I decided to keep the lower band as room adjustment.
If my head didn't have the variable hpf, I might decide to do something else. Probably a Broughton, fdeck, etc in the effects loop as an always on.

I noticed a new Neuro with EQ2 v1.15. My Neuro says it downloads it very quickly, then I click OK to update, but it immediately gives a success message, telling me to turn off the pedal. But it's not updating anything. Anyone seeing this?
I can see the update file: "SA270_EQ2_1_15_9.saxf"
Is there a way to "force load" thesae firmware files?

I had to fiddle. I removed the file from the Hardware Update folder and made it try to install, which made Neuro ask if I wanted to choose a file manually, which seems to have worked.
I'm still struggling to see why you need a 56db of cut at 40Hz. FOH is the sound guy's responsibility. Stage noise is yours.
If you have say a very efficient 4x10 that puts out say 100db /w @ 1m. If you shove around 128w RMS into that Cab, you are looking at around 120db of SPL output. That's seriously loud for stage use. Cutting even 15db @ 40hz is the equivalent of only shoving about 2ish watts at the cab. Your cabs can easily handle 2 watts at 40hz...
If you use one slider from each channel (leaving you 18 other sliders) you will get a net of -30db. A 3db gain is usually double the wattage. So a -30db drop is the approximately 1/8th of the power. So at 128w full range with a -30db cut at 40hz would be like putting 0.125 of a watt through the cab at 40hz...which is less than say an AA battery. I think your cabs can really handle that, no problems what so ever. you would struggle to hear that 40hz content at that wattage in isolation. It's doing nothing to harm your tone, cones or cone coils at that wattage.
If you are fixated on the HPF miracle snake oil claims...sure go get a dedicated unit. It's your money and your rig. However, even a -15db drop at 40hz will more than meet your actual needs. A -30db drop is way more than you actually need. The HPF is coming to the EQ2 at some point. However it's not a game changer as some claim.
The EQ2 is the most versatile and comprehensive EQ pedal in existence. It can do volume swells and wah or Low Pass filter sweeps...it can do stereo or dual channel. Each of the 20 sliders are fully parametric (not just semi parametric). However...if you just need a low pass filter network...then maybe an EQ2 is over kill for you.
Another thought for you: The new SA Ultrawave has a pair of 8 band graphic EQ channels. Each with an adjustable Low pass and High pass filters. You could easily assign channel 2 to your mono rig output to DI and use Ch1 as a comprehensive dirt / compression / tremolo option.

So... where to begin ...
I've been chasing the low volume stage for a decade + While I do own a 4x10, it is used when I provide backline only. Multi way cabs that go deep are my thing. Fearful at first, now MAS. In my own band we are not at all loud on stage the PA does the heavy lifting. Having a variable hpf in my head I find a really nice feature for tailoring the low end. Hopefully the Eq2 implementation will be shelving.
When Jesse gets the Tuner working on Input 2, then the EQ2 will be the front end of my rig, replacing a Radial BassBone. You seem to be oriented to EQ as effect, sound scaping,etc... I'm focused on the EQ2 for
- Input Switching
- Gain Balancing basses with varying output levels
- Dealing with acoustic abnormalities aka room acoustics.
- Minor EQ tweaks for basses that don't quite fit the mix as is
- Tuner working in Input 2
- The ability to adjust the frequency center of a group of sliders on a percentage basis.
The use case being 1 room I (used to) play often has a strong resonance at G, another at Ab and another at A. How nice it would be to be able to tune that out via expression pedal...
I am often playing bass, singing lead or backup, mixing from stage, setting light scenes from stage. I'm a busy guy... And my band leader calls whatever he feels like from a book of 10 years. Sometimes I need a 5, sometimes a fretless, sometimes a zingy J.
As you can tell our requirements for what the Eq2 should be are very different. Mind are focused on efficiency in a very fast paced live environment.

So for the past few months i have been happy with the EQ2 and was using it as a gate and Rat tamer and booster basically. Sweet, happy, allG...Then I have been rethinking alot in my board in the last week especially as my KMA Machines Tyler smoked a resistor on board change... Also I got the amazing Demeter vtbp201s preamp which totally transformed my world..
Anyway I did it! Using EQ2 as a midi programmable frequency splitter!
So i have the new Darkglass ADAM which with the new update enable you to configure the 2 outputs to what you want. So sending a clean with cabsim bypass from the left directly to one channel of EQ2 and then sending the full dirt signal as normal on the right. Then set it all up with stereo in mono out and EQ the two channels one having a big low cut to where it works and then the other with the 10hz highpass and the a bit of tweaking and yep!! perfection. I must admit working with a freq splitter for many months prior helped hugely in this.
Full clean bass freq on one channel and whatever craziness you want on the other. 1/4 of the size of Tyler, fully midi programmable presets, still have gate, limiter, and all of the rest and a tuner to boot!
If i want to bypass for fuzz or octave then it can be one click in midi which is something Tyler couldn't do.
Stoked!! I was researching freq splitters when I read @BurningSkies ask the question about this and got very excited lol!

I was wondering if anyone has worked out a dual pole Low pass filter patch for the EQ2 yet? Although I have qualifications in electronics...I'm not familiar how one operates on a frequency graph or how to map those ideas onto the EQ2. Any ideas?
Don’t forget that phase inverter too, being able flip the phase using MIDI is a great feature when dealing with parallel paths.
I’m going to have to give this a try, thanks!
About 20mins of playing it looks messy as but it sounds awesome. I just isolated each channel separately and ear tuned them and mixed them together same as setting the Tyler
I could share to the cloud but with EQ it is so situation specific i doubt it would be right for anyone else.

That's fair enough bud, however if you select "Shelf" on the lowest band and the highest band it turns it from a notch filter to a -15db per 10Hz slope with a max of -30db if you include the integrated adjustable HPF.
By the way...on a different subject, I've been chasing a good expression controlled Low Pass filter on the EQ2 for about a month. I didn't like what I tried, however I decided the only way was to make one myself. I found a Xerograph LPF styled patch on my C4 and spent a fair few hours A:B them until I got it right. I've also added a -30db peak cut at 30Hz to save your cones from the subby synths we are all going to use with this patch because that's what it's deigned for! Look for GMC Low Pass Filter by Gazzajagman and plug in an expression pedal of some sorts. Mine is mapped to Expression over Midi...your mileage might vary.
It's designed for bass, so the max open swell is about 10Khz and the bass cut swell is around 250hz. So wiggle the expression and the swell moves from 250Hz to about 10Khz (perfect for bass synth swells) with around 40db steep slope cut to everything above the swell frequency. If you want it fully open, or fully closed in the bass frequencies, just modify the expression control's upper and or lower frequency for Bands 8.9 & 10. Band 4 is a suppressor band to lower the middle range.
Works like a charm and I probably won't be needing a dedicated Filter pedal going forwards if I don't want one.
I have to say, this is one of the main reasons for choosing this pedal over the Boss EQ200. The option to make it a volume Swell, Wah or Low Pass Filter using midi over expression is a serious benefit. As well as being smaller and easier to power. The visualisation of the EQ graph using the desktop app is just awesome and way easier to read and dial in EQ quirks than 10 physical sliders without a mapped graph.
One other sweet feature of the SA EQ2, the option of peak or shelf for Band 1 and 10. That effectively makes one a HPF (as well as the HPF that's already there) and the other a LPF.
