i might be misunderstanding you, but i think in the situation you described you would only be in classic mode, and only using the freqd player. if both timed and freqd are being used (split mode) there should be an arrow on both.

Did I get it right now:

If you´re sure kernels are less then 10ms then you could use Classic mode with 10ms on timed and arrows pointing on Freqd

If you are not sure how long the kernels, use Split mode with timed set to 10ms.

Am I Right?

Thank you!

That explains it very well.

if you want to use timed only, the arrow should be on timed, if you want freqd it would be on freqd, for split there would be an arrow on both.

changing the kern length on timed will have no effect if the arrow is on freqd.

Of course, thats how it is set on my tweaked presets, I just messed it up in my mind trying to explain.

Ok... I'm still a hair confused here:

Timp says "point the arrows so they are going towards freqd player lengths.

Then increase the timed kernals in order to complete the sample lengths"

Then Cupwise says "if you want to use timed only, the arrow should be on timed"

In Classic mode, or hybrid, which way should the arrow point to use the timed engine on the kernel?

Thanks for all the valuable info. I'll try to summarize:

For best results:

Nebula for tapes, preamp, eq and compressors
Nebula Reverb for consoles, TB+, reverb, delay

Use split mode with 10ms kernels on timed and Evf17.

Evf17 can be set globally.

For the actual timed arrow tweak etc, you need to edit each program, and use SAVE AS (N2P files only) before edit.

These optimizations apply to Nebula and Nebula Reverb.

Work in 96kHz because of the slight src quality reduction.

The arrow should point to Freqd for best result

Timed > Freqd

Try switch to Economic mode and you see the arrows turning to Timed

Timed < Freqd


Also, Giancarlo told me in a mail that Nebula Reverb will always sound the best because of longer tails and no truncation, And it´s the only one that support multithreading.

If you set Nebula audio engine for an individual emulation preset (KERN page) to play less than the complete kernel length you will get noise due truncation, long kernel length in TIMED are not possible yet (Do you have a x32 CPU with 96 GB of RAM computer?) , so you can use split mode (SPLITH, H=kernel=harmonic) in the first harmonic called fundamental, in that case you use the best of both world, direct convolution for transients and FFT convolution for the tail and that help user to load 10-60 instances of Nebula in theirs audio sessions.
