Hi guys,

Today I checked the Ludwig Vintage snare from AD to see how many different actual samples there are.
And my suspicion was... false

...bla bla bla...

as i said i don't have any AD stuff, but again i really doubt that is the case.

AD uses their own proprietary sample format, with some kind of data compression and a variable bit-depth scheme. what are you doing to work out how many samples there are?

Please see the link to the other thread that I put earlier in this thread. I do the same procedure as digitaldrummer describes in his tutorial. I then put each of the 127 hits on its own channel. Mute all exept No.1 and No.2, phase invert No2, move the sample until it completely cancels out No.1. If it does, they are the same. Continue w. 1 and 3, then 1 and 4 etc. All samples should be normalized.

The top 8 layers have a different EQ but all 127 velocity layers are the same sample.

call me a skeptic, but maybe there is something wrong with your testing methodology.

for starters very few multisampled instruments of any kind have 127 layers anyway, so 127 MIDI velocities is not the same thing as 127 layers.

and how on earth can you conclude from a phase cancellation test that the top 8 layers are the same sample with different EQ applied?

if you create a MIDI file with the same note and velocity played 20 times in a row, do you get the same sample each time? are you sure your AD settings aren't messed up somehow?

mate, i'm not shooting the messenger, i just don't believe that AD would have the exact same sample for every kit piece, when there should be 12-16 depending on the kit. if what you are saying is correct then the entire standard AD package should only be tiny. your assertion implies that they are padding their gigabytes of samples with copies of the same sample, or just useless dummy data. it just doesn't add up.

i haven't seen your setup, or your testing methodology, so given the above, my scientific mind is skeptical.

and you didn't answer my other question: how can you tell from a phase cancellation test that some layers only have EQ applied to the same sample? that statement introduces more doubt into my mind, since it actually isn't possible to do so, unless you know exactly what EQ algorithm and parameters were applied in the first place, and can then apply the reverse EQ to the sample.

don't take it personally, i am genuinely curious as to why you are seeing what you are seeing. there are a lot of unknowns from this end though.

right, i just downloaded the AD user manual. one of the sampler settings is this:

“Single Sample” mode
Makes AD play only one single sample across the entire velocity range, and uses no alternating samples. Gives you that ”old-skool kool” drum machine feel!


have you got that turned on???
