Say after several hundred tweaks to a model it will blank out the total volume. This doesn't appear to be caused by anything specific that triggers the error that I have noticed. Will try to replicate.
If I save the tlp and restart, then reload it is fine.

Any update to the offset in the curves <~60-80hz being displayed lower and 200Hz up being too high?

I'll see if I can find a reason for this, but it does seem very random!
This is to do with the stuffing model, I am currently looking at alternatives and will update if I settle on one...
Your latest release works without issues on Windows Vista64. I enjoy using your program and appreciate your efforts.
============
Could you add one decimal point of precision on the freq and SPL displayed on the bottom left corner in the Sound Pressure Level graph? Not a critical issue.
XX.x Hz
Value: [System = XX.x ]
===========
Do you have any ideas on how to model the "resistive nature" and "resonant nature" of several deep-but-narrow slot port as used on Onken style woofer cabinets? AkaBak is the current best simulator for this level of port air flow detail. Your models may not be suitable, but I'd appreciate your thoughts.

Thanks, that's good to know
Done. I'll release the update later today I think.
Erm.. This should just model in the normal way. If you have details of a design and accurate sims/measurements to compare I'll happily look into it.
Ok thanks. Still looking into this. Its hard to find the bug as it doesn't do it for me...
Do you just mean the volume isn't calculated. Or that the model (freq response) doesn't change at all?
Edit: I think I can see the problem here. It happens when you put a branch on the first element of the model. Is that correct?

That's what was causing me to hold back reporting this, it's that blasted where, when, what, how...
Correct. The added branch doesn't change the results regardless of volume, length or dampening.

It's useful reporting these things. Just hard to find sometimes! I'll hunt it down!
I know how to fix that branch issue, just need to get round to it. In the meanwhile, you don't actually need to use a branch on the first element as it is the same as moving the driver down the first element. Nevertheless I will fix it soon.
New update has just been uploaded:
- Added a decimal place to the graph cursor readout as requested.
- Fixed the bug where the branch on the very first element would be ignored.
- Changed the stuffing model to be more accurate (More at higher frequencies, less at lower).

Erm.. I think you need to be on the internet to install it.
There is probably a way around it but I can't think of one.
Edit: I thought of something:
Try downloading this zip folder
Extract it all to a location and then run the setup.exe

That worked perfectly, thanks
No problem. Its nice to know that it can be installed on offline machines
I'd be happy to help out with a user guide. I'm not sure what you want - all text vs text and pics, what format - pdf or a traditional help file or something else, etc. We can talk about details but compiling info should be fairly straightforward. I'm not really interested in recognition, just happy to help out.
The big problem right now is that I don't have the latest version. I don't want to update and risk losing tapped horn functionality. I haven't checked to see if I can leave the old version intact and install a fresh version as well since this isn't a pressing issue for me yet.
I realize I was the one that requested the new functionality (ability to move the driver easily) that led to the removal of the tapped horn feature but I don't want to give up the tapped horn feature.
As a side note I've been planning to compare your program against MJK's to determine how your stuffing units compare to actual lb/ft of polyfil. I did it recently with Hornresp (since Hornresp can now sim stuffing in transmission lines) but I haven't got around to it for this program yet.
You can PM me if you want, to keep the user guide info out of this thread, there's quite a bit to discuss and it would make a mess of this thread.
Another update (v3.6.3.3)
I have re-introduced the Tapped Horn feature (as a dragable 'Tap') along with a couple of minor GUI changes.

Sometimes when I minimize the program to the taskbar I get an "Unhandled Exception Error" with the options to "continue" or "quit". This doesn't happen often now that I've updated to the latest version but it does still happen. When I had the older version this happened EVERY SINGLE TIME I minimized the program.
Any idea what this is?

Thanks for letting me know. Can you see any pattern to when this happens?
This was brought up once but I thought I fixed it. I don't get it anymore...
I'm not sure what you mean by this? Exponential growth is f(t) = a.b^t
a is the starting point (i.e. Start Area). B is the growth factor (i.e. Taper Ratio) and t is how far along you are, i.e. position (x / L)
