Sfzer and makesfz.pl are useful tools when you want to create instrument
sfz files. They give you an nice starting point.

I was able to contact the dev of sfzer and got some help.

Atm I wasn't able to contact the dev of makesfz.pl
Both tools expects that the samples are named in a certain way (C, C#
etc.). It seems that this makes these tools less valuable for drum
samples without such a naming.
For those files I think Lisalo with the -p, --percussive option is your
best starting point.

This tools is handy if you want to add velocity values, it works via
wine and mono. I didn't find a Linux native alternative yet

Good examples of SFZ files for different instruments would be nice to
have at this point. Atm we've the sonatina sfz files and the Salamander
sfz, I could use as example. Not sure how sophisticated they are.
