First, let me say that I love SC. It is my go-to sampler.  Light, fast, efficient, expressive.  I love it.

However, I just noticied something troubling.  It appears to be smearing transients (red box below) and altering the wave form (blue box):



(The top wave form is the original.  The bottom one came out of SC, with the default settings.)

I use SC mostly for percussion, so, a snappy attack is very important.

Is there a technical reason for this?

Thanks,
-Bill

Can anyone else confirm this? 

The only solution I have come up with so far is to insert ~70 samples of silence at the beginning, before any transients.  Of course, this is time consuming and results in a shift of timing.

Any ideas?

Thanks,
-Bill

Hmm...  I just found this in the v1.0.6 change log:

Quote
Bug causing slower than desired voice attack-rate fixed. (there was an undesired 32-sample ramp regardless of the AEG attack time, this is now fixed).

Maybe the bug is back?

I confirmed it.  This bug did not exist in version 1.0.15.  It looks like it was re-introduced in v1.1.x.



The top is the original sample.

The middle is SC v1.0.15.  (Looks good.)

The bottom is SC v1.1.2.  (Squashed.)

Interesting. I use sc all the time with chopped drum breaks and have never noticed this. At least I have not noticed any thing audible. I do not question your graphs, and would like to see this fixed, but I'm curious can you actually hear a difference between the examples? 70/44100 is about 1.4ms.

It's subtle, but I can hear the difference, especially with samples like the one shown below, where there is a transient right at the beginning.

I've come to realize that great sounding music is the result of a lot of little things done right.  All those subtle things add up to a real difference in quality.  This is just one link in the chain.  I want my drums to POP!  ...not fade in.

ya i noticed this too..it's really frustrating for drums as SC1 is an amazing sampler.

where can i download the older version? does it differ in functionality?

i think it has to do with that 0.997ms envelope thing.

I would like that also, cause that smearing sucks big time.
I just don't know if it's legal...

Well dont see why it would be a problem, an old version of now free software. Suppose if copy protection is required its understandable that people wouldnt want to include their license though.

If one kind soul out there does have a copy of version 1.0.X they would like to upload.... maybe Vemberaudio themselves could release the old versions?
