No, your are good. In the future we should switch direct convolution for everything and drop out FFT convolution. CitriQ and others DAW builders already sell 24/96 nuclear PC for 4000 euros!

I think to have a powerful hardware is our, the users problem. To buy great hardware is easyer then ever.
But yes, a lot power cost a lot money. No other way is possible for the moment. But some of us want pay for that. We love Nebula to much for less.

For a computer look here for example:

http://www.xi-machines.com/xi_de/xi_sys ... x3_de.html

Or the NVIDIA stuff like Tesla Keppler or GeForce GTX 690.

What we need now ist the right software for that. Like Nebula pure Cuda for example. And / or some more realistic information. A timeline maybe? The main problem for the moment is, we dont know what direction Nebula goes.
Is a computer like on top a solution for all? Or a basic solution plus 2 time Geforce GTX690? Or better a server solution like Dells low energy server with 12 or 24 or more "internel-server-cards"? Supercomputing is a solution?

What we need is information. The sounding difference from low latency Nebula to reverb Nebula is a big one like timp wrote. No one need golden ears for that.

Please AA team, in deep respect, whats going on?

Ok, I checked. About 64 bits buffer, there is a parameter named look ahead tuned around 1.5 milliseconds in most configurations and libraries. This is the reason of the 128 bits buffer request in nebula. You could maybe to down to 16 samples, but if nebula doesn't understand this buffer is disabled or zero you'll get a crash. Maybe we'll post a fix for disabling it completely, but you need look ahead in preamps, where it's very useful. Preamps are tuned around 2 milliseconds, so using a 1.5 look ahead nebula is still very close to hardware, and disabling it maybe it's not a good idea.

I was talking about the buffer in nebula reverb , just by changing that .

Anyway thanks G. I always wondered if the look ahead is better than making nebula run at fast prog rate?

yes look ahead is way more important imho.

ok , I've been wrong about that before then.

So should we be increasing ahead function for higher latencys? Or have i completely missed the point.

That information is already in the Nebula tips of the month.

YES, but we need a version that runs FFT for situations that need low CPU.

how about another nebula dll called NebulaTIMED!

Its just the same as nebula reverb, but forces everything onto TIMED in the best way possible for that program.

It would eliminate a lot of confusion and enable every user to experience the quality without messing about with the settings and having to create new programs

I got down to 16 samples at 48khz and got quite a few nebulas running , matched reaper to 16 blocks and the sound quality is great!

of course running at 1 sample would be amazing but i very much doubt my computer would handle it .
