Mobile Driving/Flying Cockpit with Motion and Tactile ( Build )

[Mr Latte]

@Mr Latte Thanks! I'll check to see if I left the auto-calibration on!

If these MBQ-1's turn out badly, I'll move on. I'm not worried about turning this aluminum plate into swiss cheese. I have plenty of aluminum in my shop Maybe I'll come up with a way to fit a large BK in there eventually, but I haven't found anything I'm happy with.

For tests it doesn't even have to fit below, you can extend two legs of alu profile for the BKs feet from the pedal base in some way, shape or fashion. Some people have had 2x large BK extending directly off pedals. Just extensions to the alu-frame the pedals are bolted too and then isolated with RDB 100 isolators beneath which are nice and stiff.

Anton bought the small Earthquake based on it being 600W, presumably assuming it was mighty. I even bought one at the same time just to see what it offered out of curiosity but it's still what I would class as entry-level model.

Your not an entry-level type of guy

Your not an entry-level type of guy

Fair enough. I cancelled my order. They are not coming.

Back to the drawing board...

And thanks for helping prevent a mistake and waste of my time.

I guess BK-CT's work fine bolted underneath seats so I can hang it upside down.

Not happy with anything yet, but I have a couple ideas.....

I think its a wise move.

Go buy an NX3000D amp instead !

Rather than a 304 and exciters?
I thought the idea was to get a large BK on my system right now.

Forgive me if I'm not sold on the DSP functionality in those amps compared to just filtering the signal with software in Windows before it gets to the amps. I've worked with IRR and FIR filtering in both hardware and software. There is ZERO rocket science here. 30 years ago we needed separate DSP's to keep up with an audio data stream. Not anymore.

Most software now has a combination of IRR filtering at lower frequencies where there are not enough taps for FIR to work well, and then use FIR filtering for the higher frequencies. For this application FIR is unnecessary even for the higher frequencies. The main issue in equalizing higher frequencies is upsetting the phase of music and losing the 3D imaging or spatial placement of instruments on your sound stage. That's where FIR equalization shines. It has none of the phase issues but has evenly spaced taps which work very well in the higher frequencies but have lot less precision at the lower end. Since you can't hear directionality in lower frequencies IRR makes no difference and makes sense there. IRR is also much easier to do.

I have a strong aversion to taking a perfectly good digital value and sending it to an D/A step only to send it to the amp to have it go through an A/D step so there is a digital signal to run mathematical filters only to perform yet another D/A step. That's a lot of wasted translation and it firmly goes against my grain. The BSEE in me sees that as extremely wasteful use of redundant hardware.

To put it another way, if I were to change anything it would only be which software I used to modify the signal while it is still a digital signal on my computer.

If you can show me an equalization curve, I can find a way to reproduce it in software.

The only possible use an in amp DSP would have is to add gain beyond what I can send through the analog connection. Since I'm already dialing my effects back quite a bit, I'm having trouble seeing any possible advantage.

All that said, I've made my argument and if I've missed something besides my having to manually replicate any in DSP curves you have, I'm listening. Given that we are only talking about one curve per channel and it's a one time operation, it's not a bit ask to replicate a curve.

As you go into depth on the subject...

In fairness, let me give you an example of the past here on the forums regards people talking about PC/Software based audio solutions and using them with multi-channels for our required usage case scenario.

Voicemeter Banana
Peace Equalizer APO

Are two examples I can recall that people opposing the requirement or benefits of buying DSP-based amps or additional hardware. Yet if you look over the whole 200+ page thread for tactile and going back several years, you will not find one single member that has illustrated these fully working with Simhub, using multiple soundcards, over multiple channels and providing the "how-to" or showcasing all the different crossovers or EQ that they apply to different channels.

People that highlighted these to my knowledge have also not created their own threads covering them in detail neither. Some even when asked multiple times, nothing seemed to appear that I am aware of.

I keep saying this but some of you should stop talking from "theory" of what "may" be possible or "should" be doable. Go and do it, test, experiment, find the working solution and then offer it, to benefit others as a tried and tested reliable alternative....

You are welcome to show us what is possible, presenting a "how to" and report on how well this indeed works with let's say 8 channels? Also, can you illustrate what types of filters are possible and what slopes for those filters can be set? Having to manually set curves sounds like a bit more work.

Convenience and reliability, sometimes it's worth the extra money.
The simple thing with the approach that is recommended with the NXD DSP amps is that people can very easily get to grips with it, but also we can load/share settings easily. Most users, like the ability to just power on the amp, and it's done ready to go, with the required DSP profile loaded. No issues with windows drivers, windows updates causing havoc or soundcard blips, channel crosstalk with certain soundcards, delay or stutters.

 

[RCHeliguy]

Fair enough. Challenge accepted.

I'll document and illustrate how to make this work assuming there is no limitation with 8 channels. But if there is a limitation with this particular tool, I will find one that works.

In fact I'll up the anti to including a YouTube video explaining this operation.

<Gentlemen's handshake>

BTW setting up curves is very easy to do and I will show people how easy that is

Not only that, but since the configuration files are very simple text files and you could easily cut and paste between preconfigured curves, it should be very easy to create a list for each transducer type with instructions on how to create the filters without even using the Peace UI.

If you supply the curves that you prefer for each transducer, I'll be happy to create the APO equivalent configuration files. This would also drop the cost of entrance a bit further to make your configurations more accessible.

Moreover if there is an issue with the underlying Equalizer APO, it is open source and I should be able to find the issue. It wouldn't be with the math if it is just missing channels. It would just have to be with the mapping to channels people are not using frequently enough for anyone to notice.

BUT I will add that caveat that I already know that it has an issue with Windows 11 which has likely moved the interface that they are taking advantage of right now. Fortunately I know a few people at MS and have a friend who loves writing device drivers, signal processing and a challenge.

Well I think people on the forums might appreciate that. excellent that you are up for it.

Of course, one of the unknowns is people's systems vary, so this is also a potential problem using this method. As to how reliable it may work, having it work with more than one soundcard would also be a requirement for some users as they will want to have easily over 8 channels when potentially installing exciters and other units for various installations.

Good Luck!

Voicemeter Banana

I discovered Voicemeeter recently. I purchased Potato. And I am very impressed with it, even if just discovering and learning more every day/week.

I'm guessing details are not so interesting, but the reason I bought it was to allow a better mixing of what audio signals go to the tactile, vs what goes through the headphones (or also through digital out to sound system). I found this VERY frustrating and confusing to do in Windows. And even when achieved, I found that the SimHub signal would also bleed into the headphones.

What I have been able to do with VoiceMeeter Potato.
- SimHub as software has it's own channel for signal. That channel can be dedicated then to ONLY the buttkickers.
- Software running (ie. Spotify, game, etc) has another channel. That can be put to anyoutput. So, example, if I want to run spotify through both the buttkickers and the headphones, it works.

What I'm using it for, is not quite what you guys are talking about. But for my purpose, it's fantastic (so far).

I have seen also the EQ area and options for managing the signals. Although I have not done a lot yet, I'm very interested in playing around with that. But not for tactile, more for managing certain games/software audio (example, although I love AC1, the audio just annoys me. So I am going to experiment with managing some EQ or other parameters with Voicemeeter, to see if I can find something a bit more interesting to me)

There are many videos on YouTube about VoiceMeeter. But they are quite focused on using it for streaming. But it's clearly very powerful for many uses and not so expensive.

I was going to buy an external audio interface to play around with (still might, if I find a slightly used one for a good price), but after trying Voicemeeter, there's not really a need (at least so far, for me)

 

[RCHeliguy]

Guess what?

I've been using the MB audio to drive 4 x transducers for quite a while and I can get another 2 channels out of it, but I also have an audiology 7.1 card with 8 channels that I am currently running to my AV reciever. This is mostly for when we have guests playing in VR or for when my wife streams yoga, so I can generate up to 14 channels.

Looks like I'll be ordering more 1/8" to XLR connectors and as I mentioned earlier I have hardware I've issued for room calibration that I can capture a signal to at least verify the curve coming out is what I asked for.

 

[RCHeliguy]

The Peace APO user interface only allows selecting a single device at a time which means it would limit a user to 8 channels on a 7.1 card like my Audigy 5/Rx.

However the Equalizer APO spec allows specifying multiple devices. I've posted a question to the Equalizer APO forum to ask the following:

I noticed that the syntax appears to show that multiple devices can be specified delimited by a semi-colon.

I assume that would be like the following.

Device: Realtec {Guid}; Audigy 5/RX {Guid}

1. Are multiple sound cards simultaneously supported ?
2. If so can all channels of both devices be specified independently?
3. If not would they be supported in pairs such that the FR channel of both devices would get the same filtering?

Thanks!

I will find out if there is a way to configure multiple devices. However 8 channels should be enough for me personally.

It should handle a Phase 1 configuration + 4 exciters well which is likely enough for a large percentage of people.

It does appear to default to ALL devices if devices are not specified. My guess is that would mean if you have 3 x 8 port audio boards, that the same filter would be applied to each specific channel of all 3 boards. ie. Right Front would be Right Front for all 3 boards. But I'll wait to hear back.

So far I'm more impressed with Equalizer APO's very strong set of filtering capabilities than anything else I've seen. It's quite impressive in it's scope and makes other products feel like toys. It looks like what I would have written if I had built a tool like this.

The Peace APO is a reasonable interface to represent a good chunk of the functionality of Equalizer APO, but it has limitations and I would use it as a tool to generate the text configuration file in sections that could just be pasted together.

Since it is open source, it could be extended as well.

I've just pulled up the open source C++ solution in Visual Studio 19. This is interesting stuff. It's been a while since I poked around in audio code

 

[anton_Chez]

Man all this DSP stuff goes WAY over my head.... I did have a go using software EQ, I think it was Potato or something along those lines. I couldn't be bothered going all the way into it, I think it was to try and mix the audio signal to tactile as well as the Simhub signal. But after trying the audio based tactile, it did not seem (on the hardware I had at the time) worthwhile to continue to invest time and pursue that idea. So I ditched it. I do get a little wary of additional programs running while racing. It's a good peace of mind to have the DSP on the amp, set it once and forget about it until you either change the units or want to try different effects with a different curve. So I do appreciate having it. If you already have an amp that does not have on board DSP then I can see the reluctance to obtain one at further cost when you are already very well versed in a software based solution. I only asked about it previously because I found a used NX3000 non DSP for a pretty good price and didn't want to wait forever to get my 1000D looked. In the end I bought another 1000D. The difference in price is not substantial between DSP and non, but it is there. Around 15% or so I think you pay extra for the DSP model. Also, in this current climate of short supply, some might only be able to find a non DSP version of the amp they want so it's nice to have an alternative.

On the MQB-1, that's exactly what happened. I was on the lookout for a large BK LFE for quite a while on the used market and I finally came across a refurb'ed one on Part Express. I had it in my cart for what I thought was a decent deal. I have no idea how I ended up coming across learning about the MQB-1 and from what I read it seemed to be a powerful unit, in my mind I thought it was comparable to the LFE with the power rating and also comments from users on home theater forums. When I got it, I couldn't believe how TINY it was compared to what I was expecting. For the record, it's not a bad unit, at all. But it's akin to buying maybe in between a BK Mini LFE and a BK Advance. Probably more in line with the Mini. It packs a punch, but now that I actually have the Concert, it's absolutely not worth your time if you're looking at adding another large unit.

Honestly, for the rig that you have, being mobile and pretty compact and all, I have no idea why you're trying to cram SO MUCH energy into it. I mean, I get that Rodney has like a million units and it's the way to go if you want the best tactile on Earth, but even "just" having a large BK LFE or CT and TWO TST models, you've got the potential for AMAZING feedback without adding so much complexity that it all becomes to much to manage. I will 100% say, ONE HUNDRED PERCENT, that one or two large units, placed on the seat (perhaps not directly but the way that I have it, on a mount attached to the seat rails) is the way to go over ANY amount of smaller units. Less fuss, probably not as much extra cost as you think and the overall feedback is way better since it's directed at the only place you actually will feel it in full force, your body.

I get that you're pushing the boundaries, but for me having started small, bought and sold a bunch of stuff and worked my way up to the largest unit, I would now always recommend someone to start there with only a single unit. Might not suit everyone, but that's what I personally have found to be the best route to take having already taken multiple routes.

 

[RCHeliguy]

If you prefer DSP's in your amps, go for it!

I obviously have a very strong bias about this, but I'm not saying DSP amps are a bad thing. If it gives you peace of mind and makes you more comfortable, that's great.

As for the rest. I'm playing and I am getting more discernable effects out of the single TST up front now that I've backed my volumes off.

It's all good!

FYI, I'm not doing audio based tactile. What I'm doing is simply applying equalization curves specific to each transducer to maximize their effectiveness which is what Mr Latte is using the DSP's for. So if my Left Rear channel is a BK-CT than I apply a curve appropriate for that transducer. That's all. No rocket science.

Anyway, this is all for fun!

Seems like these DSP amps should take digital audio input. Then you’d eliminate extra D/A to A/D cycle.

 

[blekenbleu]

Seems like these DSP amps should take digital audio input. Then you’d eliminate extra D/A to A/D cycle.

Getting more than 2 digital channels of effects per output from SimHub appears to be an issue. Given relatively modest upper frequency and dynamic range of tactile transducers,
multiple A/D and D/A cycles are mainly of concern if low frequency response gets lost.
Cheaper devices may have coupling capacitors too small for frequencies much below 20Hz.

 

[RCHeliguy]

This is getting interesting....

It "appears" that Windows only has hooks for a single multi-channel card and that SimHub is actually moving data to additional cards in a non-supported by Windows way.

So based on this it appears that Equalizer APO is limited to 8 channels total. It doesn't have a place where it can insert itself for additional channels that don't "fully exist" but are still being driven by SimHub.

However... I see an opportunity to build a plugin for SimHub integrating this signal processing into each channel at the output stage. We would only need High pass, Low pass and equalizer features to be effective.

I'm still figuring this out.

That said, given I am unlikely to need more than 8 channels anytime soon, I may just go forward with documenting how Equalizer APO works. That is BY FAR the path of least resistance. The rest may be more of a side project.


I have put in a feature request for some filtering options to be added to the output channel configuration in SimHub and included a link with example code showing how to add the filtering directly to the signal path in SimHub.

 

[RCHeliguy]

Shazzam!!!!! It turns out that Equalizer APO can handle EVERYTHING !!!!!!!!

It's not that complicated!!!!

1. Use Peace APO to configure each device and save each card's configuration to a separate file.
2. Concatenate the files together.
3. Just make sure that the name of the concatenated file is listed in the config.txt file.

You can equalize every audio device that Windows recognizes !!!!

@Mr Latte I'll verify it works on my 2 audio card configuration and create verbose instructions and an instructional video as promised.

Response:

---

If Equalizer APO doesn't need to reroute the audio from one device to another then it's capable of doing what you need.

And if the audio cards are shown as just Windows audio devices then everything is possible.
Example of a (random) multi-device multi-channel command file:

Device: Realtek High Definition Audio Speakers
# boost base on all channels of my speakers
Channel: all
Preamp: -4 dB
Filter 1: ON LSC Fc 166 Hz Gain 10 dB Q 0.4
# a little bit more on the front speakers
Channel: L R C
Filter 1: ON LSC Fc 166 Hz Gain 2 dB Q 0.4
Device: Another device
# again a bass boost as just an example
Channel: all
Filter 1: ON LSC Fc 400 Hz Gain 5 dB Q 0.4
# etc. etc.

Also SimHub may have virtual devices like VoiceMeeter has. Although Equalizer APO directly support the A1 to A5 virtual devices of VoiceMeeter, it could be that you can select the SimHub devices in order to equalizer them.

I've got the basic idea worked out for how to interface a large BK to my foot plate.

Move the 40x40 cross member all the way to the back of my rig and up 40mm.
Mount two isolators off of that cross member about 6" apart
Run two pieces of rectangular aluminum tubing 2.5"x1.5" OD between the footplate and the crossmember.
Bolt the two pieces of aluminum tubing directly to the foot plate on either side of the TST429.
Suspend the other end of the tubing from the isolators mounted on the back of the rig.
Bolt a plate between the tubing and mount the BK-CT to that plate keeping it as close to the foot plate as possible without interfering with the TST429.

This will move the BK-CT back and submerge it 2.75" from the top of the foot plate, but keep it high enough not to interfere with anything under it. I think this could should work well and be aesthetically pleasing. believe that the TST429 and BK-CT have plenty of energy to move this combination.

Perhaps lots of work but it can be done man and you are more than capable on the technical side to do things have proved that many times with already what you have done with this build.

Ideally, having the TST429 in the seat and better connected for the seat to work with the large BK Concert and then move the TST329 to the pedals with a front BK Concert. I think you would get more benefit of the 429 in the seat than the pedals.

Even as a unit to enjoy music with as it is one of the more musical transducers we can buy.
Of course, using an EQ suited for that usage scenario.

Do this right and with whatever DSP solution (can work well enough) you will also be able to have very enjoyable control of tactile from "game audio" for flight sims or typical games.


Regards The DSP
When it's up and running, tried tested with the path you want to take then that's maybe something people can consider for their own tactile configurations.

Really though, the vast majority of people that follow tactile on these forums, looking to get or power the large BK models, do buy the recommended NX3000D amp with the DSP and as covered it still seems to be the best-priced amplifier for the large BK with a full DSP functionality.

Few people (like even with your own rig) need 4x channels with the wattage the NX4 6000 offers, so its not the best option or the wisest choice. 1x NX-3000D 1x NX-1000D is the best purchase for what we are doing. That's why you see so many people have and continue to buy those for this level of hardware. The price of buying the non-DSP version of the amps, is not that much cheaper to warrant all the extra hassle and you also get features like the digital wattage limiter.

So for a lot of people, they won't care of needing a software-only-based solution that has still yet to be tried/tested on multiple soundcards and on multiple peoples systems or if Win11 adds further complications down the road.

This isn't that bad. I've already sourced the aluminum tubing and have the solution pretty well mapped out on my head. The 2" x 1.5" seems right to me, but is only available in 6063. Anyway I went ahead and ordered another BK-CT to match the one I have.

Edit: Aluminum rectangular tubing, some more aluminum plate and a bit of aluminum angle ordered to complete this design. The materials and BK should land about the same time.

Agreed that ideally the 429 would be on my seat. I only had a fleeting thought about this because I was concerned about it adding to my rig's footprint with this TST in a horizontal configuration, but it isn't far behind my h pattern shift and realistically only adds about 1/2" to the overall width if I cantilever it to the side and mount it horizontally. So I've already grabbed a small piece of aluminum and punched the hole centers. The other mount was scrap. Since this will be more visible, I'll finish it up to a clean look.

Thought you might appreciate the B/W image

 

[RCHeliguy]

So for a lot of people, they won't care of needing a software-only-based solution that has still yet to be tried/tested on multiple soundcards and on multiple peoples systems or if Win11 adds further complications down the road.

By virtue of how this works, the sound card being used is irrelevant.

Equalizer APO simply takes the SimHub signal and applies filtering before the signal even reaches the sound card.

Easy peasy, lemon squeezy

This is a very good solution, has a very tiny CPU footprint and should have nearly zero latency. The breath of signal processing it supports is pretty advanced.

There are still people actively involved with this project and when Windows 11 if finally released, it will either work because Windows in their final release decided to maintain compatibility or they will update the software.

DSP processing in an amplifier is a great feature when you are using these amplifiers on the road with a band. The sound engineers get things dialed in and throw them in the van and set them up at the gig. That's the use case.

If I were ever using my amplifier by itself it could be a must have feature. However since I can't use my sim without firing up my powerful modern gaming computer, and that computer has cores to spare idling, I consider the setup of Equalizer APO miniscule compared to everything else.

Right now I'm running:

iRacing
Trading paints - for liveries
VRS telemetry logger - for virtual racing school comparisons
Crew Chief
Steam Virtual Reality
NLRv3 Motion System
SimCommander to control G-Belt actuators
SimHub for tactile
Sometimes Discord

Equalizer APO is a tiny tiny load compared to any of these.

An earlier complaint was that there was no documentation for this, and I'm going to fix that issue making this an easier option for people to consider.

Now that I found out there are no limitations in driving as many sound cards as you want with this software and it is a viable option for any filtering we could need, this should be seen as just another option that you can choose to use or ignore.

No one is forcing anyone to give up their DSP amplifiers.

This is all good. There is no downside to having another powerful tool that works.
