Chorus is working on my FX5200, but it's crackle-land with just one instance @ 44.1K.

Something else I noticed, in WaveLab at least, is that if you stop and then re-start playback, the delay plays the remaining echoes that was about to play when stopped.

Nils, would a GeForce 7600GS AGP be sufficient for this type of processing or is PCI-e actually required?

Mmm.... So what HAPPENED to BionicFX anyway?
All I could find was this:
http://www.dce.harvard.edu/pubs/unlette ... l/cann.jsp
It's from Harvard, and apparently he was in Wired as well... and applying for a patent... all sounds pretty serious, but the BionicFX website is no more.

Hmmm, chorus gives an error when starting Cubase (Radeon 9500pro here), here's the log :

Seems that your system didn't notice that the path env variable has been updated. Should work when logging off and logging in again.

Newest version of the delay is working on my ATI Radeon 9550.

The chorus starts but put the db meters to full and stay there
with no sound on the output.

Also noticed that if you load the chorus on a track where you
already got the delay going will make the delay stop working
and if you remove the chorus then EnergyXT terminate and you
are back to the desktop.

my pecs:

intel p4 3.2ghz, 2 gb ram and geforce mx5200.

the delay works great, i can load quite a lot of them without any crackles at 256, 512 and 1024! nice work!

but when i load the chorus plugin energyxt quits without any error message or so

still, congratulations, great effort!

@ddummer I'm just experimenting, I also noticed that, when using different plugins that refer to the Ogre dlls it leads to problems.

I already thought about throwing all the Ogre stuff away and writing my own engine, resulting in a smaller app and with less dlls, but will loose the ability to switch to OpenGL later...

I'm not sure yet..... Maybe the Ogre guys have a solution for me...

Noluck here.. restarted, dll not found again. Put dll in system path environment variable, still nothing. Copied the .dll to system32, still the program doesn't see it. Seems I will give up here

Nils Schneider · Post by **Nils Schneider** » Sat Oct 07, 2006 3:39 pm

Could you post your sgpu.log please, it should clear up why the dll isn't found.

From earlier posts...

Google this: D3DXDLLFebruary29.zip

Install it, worked for me

(add to FAQ.... hehe)

This is understandable, but it is also true that such 'complicated plug-ins' can work as good on normal multi-core processor. While with such 'externalized' plug-ins you'll have problem of synchronization (you can't process effects without latency at all) and - as I see it - problem of programming flexibility: in most cases you'll be forced to code in machine language, you have some constraints on memory (including local memory) and execution flow as well while creating complex plug-ins may require more of programming flexibility than you need for simple plug-ins (you'll need complex branching, C++ classes, large code size, look-up tables, gigabytes of memory space for sampler plug-ins).

Just to be clear about my attitude (some do not perceive my critics well enough it seems): it is perfectly OK to code and release such GPU plug-ins as long as they work, but as for me (as developer) I see problems with them, and so I do not want to play this game.

gonzo · Post by **gonzo** » Sat Oct 07, 2006 4:15 pm

OK, the February DX update thing did it. Still, the chorus puts the meters all the way up and emits no sound. Bah.

Can you get this code working on my gfx card please? That would be a HUGE step forward (wrt. complicated stuff).

Right now I am using it as VST and it eats my CPU for breakfast...
