The cheap effects are also working with SM2.0, because of this, they are running. But more complicated effects can't be programmed on SM2.0 because the instruction limit and the lack of other features like dynamic branching etc....

Okay, that makes sense. I was going to ask if you had any plans to make use of SM3, since I didn't have the attention span to actually read your whole first post.

So you asked what could come up next. So you might want to check out this one here too

http://www.nilsschneider.de/temp/GPUChorus.exe

It's a 6 (!) voice stereo chorus

Parameters:

- Depth
- Mix (0% = dry, 100% = wet)
- Speed
- Gain
- Spread (0% = mono chorus, all 6 voices in the center, 100% = 3 voices left, 3 voices right)

Using shader model 2.x (as 2.0 but with higher instruction limit), it might not run on all graphics cards. Have fun trying

OMG!

Never thought I'd get so excited by a chorus.

Thanks for this.

Hi,

Did a quick test,. works fine

Question : is there a way to have higher blocksizes ?
because i normally work at higher sizes due to my 'slow' CPU hehe.

Cya,
Rob.

Not yet, but I already got a solution in my mind

So that should be a problem of the past. Maybe tomorrow, but no promises

re: chorus

Doesn't install too well here. FL sees it as gpuDelay still with 3 parameters, sliders do nothing

That's why you'd be better off releasing your GPU experiments now, as opposed to waiting for any other steps in GPU audio development to be taken. Also, it would be absolutely fair of you to spec models of video cards your plug-ins are designed to work on so that you're not held responsible for incompatibilities; I think many people would happily change their video cards to your spec if you release a convolution plug-in to run on it.

Oh dear! I just tried the two latest versions of the delay and they now don't work on my system.

The version 2 of the delay (could you impliment version numbers in future so we can identify each version?) creates this exception:

Error #:8
Function: FileSystemArchive::changeDirectory
Description: Cannot open requested directory data.
File: \sgpu\source\ogre\Ogremain\src\OgreFileSystem.ccp
Line:141
Stack unwinding: <<begining of stack>>

Version 3 of the delay loads but on play back it crashes ACID 6. I'll just have to go back to version 1 which works fine on my system.

I tried the chorus and it loads ok but there is a glitch on playback and then no sound - the track meter shows an overload of audio.

I've just found out that when I uninstall each version the .dll is left in the VST folder (I'm not using the default Steinberg VST folder.)

I can confirm that only the first version of the delay is working.

All the others cause an exception error,pointing to msvcp71.dll

edit: I un-installed for a while and after that all delay versions are working but the Corus is still the same..

10 instances in Chainer produce 1.5% on the CPU meter within Chainer but the task monitor jumps between 4-18%...

the chorus gives the following error in cubase sx 3.1.1.944

Please re-read my comments. You probably do not have a clue what kind of words I have written. I was giving solutions to problems - not putting down this effort. Anyway, I have my own expectations and attitude - this is right, I do NOT like outboard processing - be it UAD, Powercore or GPU processing. Beside that quad core processors are already available. I just do not know what to fight for here.

Why not release the GPU plugins you've developed and we can help you test them like we did with Nils GPU delay?

There is no reason for me to release my GPU plug-in, because it does not work stable enough, and because I have frozen its further development. If Nils plug-in is working fine and without any problems, this is great. But my vision is probably a bit more conservative, because I won't think this is success until it works on 99% of computer systems. I mean, I do not have any interest in commercial solution that readily works on 30% of current computer systems only: because, frankly saying, this will be one big problem.

Yeah, I think with the growth rate in CPU speed it's probably too much trouble anyway having to keep up with all the changes on the gfx hardware side...

So I guess this brings us back to saying "get a faster machine" if you want more power

Or because you're lying and you haven't actually managed to do it.
