Less quality importing samples

[nunoabelha]

Hi, i have a lot of samples in my fantom G, the problem is: they loose quality, the sound seems like don't have any brigth...it seems like we are listening a bad quality mp3..anyone knows why? they were all imported in waves 16b 44.1k.
i saw the dan tutorial, and i'm doing everything like him..but i really am sad with the sampling quality.

thanks

Sounds to me like your mastering effects are on and are changing the sound to what you heard on computer.

Hi Flumpster, i did the patch initialize, even with my efects all off the sound seems to tiny..i try to eq the sound and aply some efects to seem like original..but is not the same...has the sample g any kind of paremeter of sound quality (sample).

thanks

[Flumpster]

The only thing I noticed with my samples (and this is with ones created on the G as well) is the gain seems to be low. I just adjust the volume of the samples but your hearing is possibly a lot better than mine ( years of having a keyboard amp right next to my head on stage when younger.. lol ) and you can hear something I can't.

Can anyone else comment who's using samples that they have compared on computer and G ?

[nunoabelha]

Yhea, my gain is like yours..i don´t know...maybe i'm being to much perfect..

There is an answer to ypur question.
Roland Fantom G lose some high freq when you import samples and FG do it on purpose because it is Roland philosophy and it is very good option in many situations(samples)
If you want to have your samples sound like original samples then you must do Emphasis on them.But there is oe problem when you do this all samples with emphasis option on will sound much brighter in othe samplers or computers.
1.Go to the Sample list and press Sample edit
2.Press Modify
3.Press 2 Emphasis
4.Use Over write function if you don't want double samples.
5.Select PreEmphasis and that's it.
6.Use this PreEmphasis on every sample with Over write function and everything will be OK.
Also you have DeEmphasis optionto reverse this.
And there is another solution for this if you dont want do touch your samples.
Dont do the PreEmphasis and just go to the PATC PRO EDIT and go to the TVF and select LPF and put RESONANCE on 12-14 and you will have the same samples like on PC.
Roland did this to gain some quality and to eliminate noise and other stuff that we dont want it in samples.
It is a nice option.And I rarely use PreEmhasis.I like what Roland do to the samples.
There was another thread where I was asking the same question and Artemy gave me an answer directly from ROLAND.And thanks to Artemy I know this stuff.And maybe you could find this thread and read Artemy's post.It is much better english explained Roland philosophy in cutting some samples high freq.

Yes, Branko has it right - preemphasis should bring back your samples luster.

Essentially, the Fantom has a 6db lowpass filter @ 12khz in the output stage. Internal samples are already preemphasized. Adding resonance may be another option, but that could introduce other artifacts you may not want. Of course, try both and see what sounds best to you.

I just did a test using 24 bit Wav files - the ones imported straight into the G and converted by it, had more noise than the ones that I converted to 16bit before importing. So maybe make sure you convert them first. They are possibly imported with slightly less gain to avoid clipping?

[branko]

And what about 48000 hz?These samples are also converted by Fantom G when you IMPORT them.What is happening then?

[nunoabelha]

Thanks branko..great help..i'll try both option...

[dbijoux]

Yes, of course, any conversion from 24bit to 16bit is going to introduce quantization errors. This is where dither noise comes into advantage.

The industry stopped using emphasis back in the 80s. Roland use it because their Library samples are legacy back to then and they used the emphasis scheme back then.
so they have to have de-emphasis set on the outputs of many of their devices. not all but many. The V-Synths doesn't de-emphasize for instance. The problem is that emphasis is a high frequency boost so if you sounds are close to normalized and you add emphasis you have just clipped your samples.. They need to put gain reduction systems in at the sample level. any Normal sample imported without emphasis applied are not operating a design spec sample frequencies. Cymbals and Hi Hats at near normalization will clip after adding emphasis.. without gain reduction routines you will ruin your samples.

[dbijoux]

Not sure why you're burning a torch on this one. It seems rather logical.

That said, at least you're not completely full of $#^&. You do bring up some valid points.

However, there's one limitation - most of us can't even hear where most of the distortion could be taking place - above 16khz. It's actually one of the times I would be cautious to trust my ears, especially with crispy hats.

Also double-check your samples again with a good set of headphones and at high volumes. Most noise and phase issues on samples go undetected.

[branko]

The wavedata information sampled with a Roland S-7x Series and XV series samplers is treated with a Frequency Emphasis boost, which pumps up the high end. When the Roland plays the sound out of its outputs, its internal hardware filters compensate for the built in frequency emphasis, making the sample sound normal again.

Actually, all samplers do this, but the Roland did it intentionally with a much greater effect than normal.

What this means is that if you transferred normal 16-bit wavedata from any other source to the Roland, and then played it through the Roland, it will sound duller since the outputs would be de-emphasizing the high end, without the data being emphasized first. Conversely, any Roland sound data you play through another medium will sound tinny, since the frequency emphasis is not being filtered.
