Hy!

I've create an amen preset, and then copy the groups, and playing it (i wanted to make a parametric eq, i have read it here somewhere...1 hp layer 1 lp layer, 1 bp layer....)

BUT IVE GOT A STRANGE FLANGEING EFFECT!!!!

Please help me, how to kill that flangeing effect...[/u]

of course it will flange.

Any sample with common harmonics will do that even if they are not in the exact same range.

Also, since you are probably not trigering the samples at the exact sample start point (e.g. MIDI delays are ms's) you will get flanging.

Lastly the filters aren't hard "walls" - they have a nice curve response.

When you superimpose two waves with similar or close harmonics, they will interact.

You either need to make the frequency gaps much larger, or pan them hard so they are in their own place in the stereo field to avoid as much interaction.

Here's a good page to learn why your samples are flanging - its actually nice effect to use by layering samples and also modulating the playback speed slightly by controllers - so you can truly simulate tape style flanging.

You need to FIR the samples for one thing. Even if you don't do any eqing to the samples, the FIR will make sure they are in the same phase. That could help...

Now... In Cubase, if I record the amen and copy the break to another channel with out moving anything, the samples will simply get louder. Now, for a filtering effect, I played around with at least three channels of a break and by inverting the phase on some channels, I was able to make a filter sweep by simply moving the volume slider on the mixer up or down. What happens is this: When the level of the two channels are equal and one channel has a shelf at say 2000 hz at 3 dB, the part of the sonic body that is not effected by the shelf will disappear. Now, if I move the slider up all the way on the channel with the shelf, the break would sound pretty close to normal. I think this is the kind of thing your after...

Now, here is the tradgey: The emu's timing is not perfect. So, when you hear flanging, what is occuring is the sampler is off on the triggering of the two samples. The FIR, as I stated may help remedy this, however, it can't remedy the timing issue that can occure. The best thing you can do is set up the preset with each sample being triggered on the same key in the same preset and do not try seperating it out over different midi channels. But, that may not even help.

OR an easier way is to:

Mix the samples in your PC so that the layers are premixed ie. you get your break layering done in e.g. Soundforge so that the timing is exactly on to the sample and you know exactly what its going to sound like when played back. then dump these into the sampler (e.g. via SCSI or via a FAT32 drive if you have EOS 4.70).

Trigger these different pre-mixed breaks at the right time in the track so you are not actually attempting to layer them at once.

That way, your not at the mercy of MIDI jitter and you don't have to muck around forever with filtering.

This also gives you more precise handling of sample start points via controllers/cords for nice b...b..b...b..reaks and gzzztttt...squarepusher type effects :^)
