Need help creating definition.txt for Drumkit

gmeader posted Oct 6, 07:31:

I'm trying to create a definition.txt file for this drumkit:

I see that there is a way to define choke groups (%mutegroup), but there's no example provided in the documentation and I can't figure out how to make it work. Could someone provide an example, perhaps using the filenames in the drumkit (above).

Also I don't know what to do with the multiple numbered files for each percussion instrument. Are they velocities or are they to be used with %seq randomization.

I'm trying to use this documentation to figure it out.

The question is somewhat out of scope: sfz is only partly supported and that's only in Alex's build. So make sure to use that one. Also I suppose using both the defintion.txt and the <name>.sfz will be confusing - if possible at all.
I'd say, take a look at so you can understand what you've downloaded, ie what the multiple numbered files are.
Next you can decide on what to use for the samplerbox sampleset - and how.
Questions arising then will be more likely in scope of the samplerbox.
Hope this helps.

Thanks Hans,
You've given me good clues to figure it out.
The drumkit is downloaded in a 387MB archive file: salamanderDrumkit.tar.bz2
That file extracts to a directory named salamanderDrumkit that contains several .sfz files and a directory named OH that contains 537 .wav files. I am not trying to utilize the .sfz files at all. I just copied the .wav files into my /media/10 drumkit folder and now am attempting to create a definition.txt file that will allow SamplerBox to use these wav files.

Looking in the ALL.sfz file does provide some clues. For example, below is what's there for the crash1 instrument:

There are 3 sets (groups) of files.

  1. 6 files with crash1_OHFF in the name are for velocity 60 thru 127 (midinote 55)
  2. 5 files with crash1_OHP in the name are for velocity 1 thru 59 (midinote 55)
  3. a file crash1Choke_OH_F_1.wav for choke (midinote 54) tagged as group 2
    It seems like the sets of 6 and 5 files are meant to be chosen randomly (according to some probability from 0 to 1?)
    The off_by=2 opcode means that if midinote 54 (tagged as group 2) is played, then any midinote 55 sounds are choked off.
    There is a different volume opcode for each group

So I am wondering what is the proper way to create SamplerBox definition.txt entries for this example.
(I realize additional definition.txt entries need to be created for all the instruments)

<group> volume=-12 amp_veltrack=100 ampeg_release=0.6 key=55 loop_mode=one_shot lovel=60 hivel=127 off_mode=normal off_by=2 // crash1 ////6 Samples Random!
