Hi,
I posted this some days ago on the "Soundfonts and MIDI" forum, I'm reposting it here because it might be more pertinent (and I didn't get any answer over there).

I've got a SBLive Value and I use WinXP Pro.
I downloaded and installed the kX drivers version 3528. The first installation crashed (BSOD), but the second went fine, the drivers work and having low latency is great.

Anyway, I'm experiencing some problems with a soundfont I often use, the famous (I believe) "Melotti drums", a great free acoustic drumkit.
As far as I can tell, this soundfont should NOT be affected by the known soundfont issues listed in kX docs. Indeed, my problem is different.

This soundfont is carefully layered and dynamically balanced, so that different samples are played according to key velocity, each one increasing in volume as velocity increases. This all works fine with the official Creative drivers.
With kX drivers, instead, the sounds do not correctly respond to velocity.

As an example, I'll report the first two things I noticed:

1) the open hi-hat key normally triggers both an "attack" and a "body+decay" samples, even when played at low velocity; with kX drivers, instead, only the "attack" sample is played until you reach a high velocity value;

2) various drum sounds seem much more flat with kX drivers, as if their intensity did not vary according to velocity, or as if it varies within a much smaller dynamic range.

I created a simple Cubasis track which can be used to hear these differences, when played on two systems with the two different drivers installed. I can provide it, and also the resulting audio, if needed.

Does anyone have any clue about this? Using that drum soundfont is very important to me...

Thanks a lot!
