Problems & Faults with sfz sample sets

[asbak]

Firstly, thanks to the creators and AVLinux for making some great sounding sample sets available.
I tried out a couple and found some issues.

Blocks has a bad keyrange which crashes Carla. The sfz has this presumably bad hikey value.

Code: Select all

sample=4_Gb_d.wav
lokey=76 hikey=888 pitch_keycenter=78

which should be

Code: Select all

sample=4_Gb_d.wav
lokey=76 hikey=88 pitch_keycenter=78

(Fixes the issue on my system)

Harmonica contains a lot of "white noise" type sample issues on most keys making it unusable. (Wordclock mismatch? Unless my download got corrupted somehow and the one on the server is OK?)

The BrushKit's hihat HH_Brsh_O.wav (Bb?) isn't closed when playing the Ab or Gb (I'm not knowledgeable enough to know how to fix this)
The Bb also sustains for way too long, the loop is noticeable as the release envelope slowly runs down.

Hi,

Thanks for the heads-up, I have fixed and re-uploaded the "blocks" sfz according to your suggestions, the others I will leave to Jeff when he has time as he is the brains of the operation... I'm just the janitor..

Blocks has a bad hikey value... which should be 88

Yes. But if it crashes Carla, file that as a bug.

Harmonica contains a lot of "white noise"

Whenever you have this scenario, check to see if the samples are 32-bit. Lots of linux apps don't read 32-bit wave files properly. You need to convert them to 24-bit or 16-bit. Again, file this as a bug with the software app.

Here's a 16-bit version of harmonica.

(Glen, replace the old version with this. I forget to down-sample the final waves).

BrushKit hihat isn't closed when playing the Ab or Gb. also sustains for way too long

Can be "fixed" in the sfz, but since I've recently come across better brush samples, that kit is going to be completely replaced eventually.

linuxsampler has added support for 32 floats in a 2014-09-11 SVN update. Also you can convert the samples to 24 bit for example with "sndfile-convert -pcm24 file.wav file.flac" (to make flac samples, which would require editing the SFZ file to change the filenames).

Many thanks for the help & suggestions gentlemen. I've filed bugreports regarding the crashes and the possibly missing 32bit float support in Carla.
