AWave Studio, a Windows tool, was able to create a DLS or Mobile DLS
sound bank with MP3 compression. (http://www.fmjsoft.com/awframe.html)

I have sounds in SF2 format already which I would like to use, and I can
convert to DLS or EXS24 format with the AWave tool. The DLS files
produced by that tool work fine with the Sampler unit.
So I'd like to convert my SF2 or DLS file into an AU Preset so I can
compress the samples. Do you know of a tool that can do this?
AU Lab reads my DLS file but it doesn't extract the samples to individual
files when I save a preset file. It won't read my EXS24 file (but it
appears to contain hard-coded paths which are not valid on my Mac).
