S950 Sampling hot on the inputs!  Reply with quote  

Hi, does anybody fancy doing the old trick of sampling into the s950 but at very high levels. I have only heard about people doing it, but never heard it myself. From what i can find on the net, it's sampling to loud and at low sample rates that gives a sound unique to the 950 and poss the 900 too? This is something that i have never come across in another sampler, and is a bid no no in basic sampling practice. So anybody up for putting a classic drum break to the test?

Cheers.

So here is what you get with a hot signal.
The input stage of the 950 works like a kind of compressor when the signal is louder. And it also add distortion (but not that terrible digital clipping like all the soundcards)

The example include the following samples:

1. Original sample from vinyl (recorded direct to the PC)
2. 1 sec silence
3. sampled "normal" at bandwidth 19000
4. sampled "very hot" at bandwidth 19000
5. sampled "normal" at bandwidth 8000
6. sampled "very hot" at bandwidth 8000
7. 1 sec silence

just to compare the bandwith I rearranged the samples from above

8. "normal" 19000
9. "normal"  8000
10. 1 sec silence
11. "hot"    19000
12. "hot"     8000

I recorded all the samples to an Audio Editor (Adobe Audition) analyzed them and corrected the volumes to get the same average dB

Here is the second file: Its the same as above except that every sample is normalised individualy to -0.1dB (this process is sort of the "makeup gain" or "auto gain" on a compressor unit or plugin)

I recommend to download it and take a look at the waveform in your audioeditor to also see whats happen to the signal.


BTW the MPC2000 (i dont know about the other MPCs) also get a nice distortion effect when the input stage is driven hard.
My Casio FZ1 dont accept hot signals. A hot sample will get the annoying digital clipping.

peace

Thanks alot man, some very interesting results. Although i got a little confused as to what sample i was listening to at points. Never the less i think i just like beats to be "one louder" than they were before, and the hot input samples "feel" louder, and i expect it to be the distortion coming into play, as you say some sort of compression. I too have a Fz1/10/20 and none of them like a hot signal, if anything it's better to keep it quite a bit under, especially at 18 or 9 khz. This is the only sampler i know of that can be abused in this way, an has never been sold as a feature!

Thanks again, J

*Edit* Ok i fully understand what is what now, bit tired still, just got up!

You got the FZ20  Shocked
Congrats

BTW do you know that xtra ring of the FZ when you set the loop crossfade (doesn't matter if you got a looped sample or not. Just set the crossfade to 0001 and your done)
This works especially when sampled at 18kHz and played back a few semitones lower than the original speed.

peace

Yea it took along time to get one, and it's not all that great. The HD setup is 50/50 if it will work and it's not possible to load/save single samples, must be banks only - basically entire memory dumps. This also goes for saving, if you save it takes up an entire 2mb regardless. Fz-1 with memory upgrade is much better imo.
I only learned about that 0001 crunch trick recently, i do everything that way now, makes all the samples really crispy.

FZ forever underrated.
