Any day soon now drobilla will get his persist extension finished and
shortly after that we can likely expect a fully functional calf
soundfont player, one that saves/restores its settings but until that
day the best we have in the land of LV2 sample players would seem to
be composite, which I seem to have working quite nicely under A3
although I've not played with t much yet. I've found this script:
http://code.google.com/p/hydro2sf2/
but I'm wondering if there is a tool that will simplify the conversion
going the other way ie to convert an .sf2 into a .h2kit fit for use
with composite (and hydrogen, of course)?

I'm wondering if a straight sf2 to h2kit would actually be possible
now. I've not been able to find any docs on the h2kit format but
through browsing the hydrogen forums I'm now concerned that h2kits are
limited to 32 instruments/samples/notes? On top of this the minimum
note number I seem to be able to trigger under composite is MIDI note
36 (C2) so it would be a bit confusing if I have to transpose notes in
the conversion. So - Gabriel or any of the hydrogen devs - would it be
possible to convert a piano sf2 (for example) to a h2kit without
sacrificing a number of octaves?
I realise I could get from a sf2 to a h2kit by using a combination of
swami and hydrogen (or composite-gui) but a script would be much
easier if it is going to be possible in a nice way.

SF2 is a general purpose format for creating multi-sampled
instruments.
H2's drumkits are a specialized and much more limited format
for creating simple playback triggers with 1 Note == 1 Drum.
...so, converting SF2 to H2 is not a straightforward
conversion... and would require some clever logic and
assumptions about what the SF2 "is" and how they "should be"
in H2.
The drumkits in H2 are specified in an undocumented-but-
easy-to-grok XML file. (E.g. see
/usr/share/hydrogen/data/drumkits/GMkit/drumkit.xml) You
put all the audio data in WAV and FLAC files, and then use
the drumkit.xml to declare how they fit into the kit.
Probably the most advanced feature of H2's drumkit format is
called "layered samples" (or "layers" for short). It allows
the sampler to pick a different sample file based on the
incoming note velocity. I only bring this up because that
part will be harder to grok when reading the XML files.
HTH,

Is it true that h2kits are limited to 32 instruments?
Thanks G!

The instrument id is a string... so don't pay much attention
to the number.
The first instrument you add gets mapped to 36.
The next is 37.
The next is 38.
etc...
Instruments are added in document order (the XML file).
Yeah, it's not the greatest system... but that's what we've
inherited. :-)
A good point of reference would be to compare the
GMkit/drumkit.xml to the General Midi spec for drum note
mappings: http://www.midi.org/techspecs/gm1sound.php
Is it true that h2kits are limited to 32 instruments?
I don't think so. I don't see any limits in the code....
and if there are, I'm sure they're arbitrary, compile-time
software limits that are simple to change.

Hi Gabriel , hi list,
There is this "makekit" script by GarryO that eases the process of
making an H2's drumkit, layers and all. I find it very useful. See:

Thanks for pointing that out Pablo - thats half of the script sorted
out. Problem now is that there doesn't seem to be a quick and easy way
to extract the wavs from a .sf2 under lx. You can export them one at a
time from swami but thats the only way I've found so far although I'm
sure there will be a few apps that will run under wine capable of
doing this. I was surprised fluidsynth can't do this.

Hi Pablo!
Here's one handy option, which I've confirmed runs perfectly under Wine:
http://audio.clockbeat.com/sfZed.html
It's an SFZ editor, but it can convert SF2 files to SFZ format, and in
doing so, it dumps out all of the individual samples as WAVs.
Thanks
Leigh

No need for wine.
Swami can extract samples as well. Just select all samples and use context menu. _______________________________________________

Has anyone ever gotten this to work? It yields
an SF2 file all right,
but I can't seem to play it in fluidsynth and sfinfo says:
"unrecognized audio file format [error 0"
I'd be interested in converting kits to SF2, gig, or SFZ, because
hydrogen has the annoying habit of truncating samples when receiving
midi noteofffs.
Cheers,

You can disable this in Hydrogen's settings; I forget where, and can't
look it up right now, but it's definitely there!
