ld10k1 (and the emu10k1 ALSA driver) still need a bit of work before
they will be as full featured as the kX driver.

The ld10k1 API provides a very thin layer between the DSP microcode and
the ALSA mixer API, creating standard ALSA mixer objects on the fly for
the control GPRs.  ld10k1 currently just loads the DSP patches.  The kX
driver OTOH provides a pretty thin C++ wrapper around the DSP patches,
which lets them have custom GUIs, load, unload, and generate microcode
on the fly and control everything with midi.  It can query the kernel
part of the driver what hardware is available and load specific patches

Many of those plugins are free (some speech, some beer).  There are also
many free plugins (well patches anyway) available with the OSS driver,
and floating around on the net from miscellaneous soures.  It would be
good if someone had time to assemble them all and figure out what works
and what we can redistribute.
