Announcing the first public release of the hexter DSSI plugin.


hexter is a software synthesizer that models the sound generation of
a Yamaha DX7 synthesizer.  Now you can have the sparkling, richly
evolving sounds of this classic FM synth on your Linux workstation!

There are a few things still missing from hexter's emulation of the
DX7 (and it doesn't attempt more general FM synthesis like Native
Instrument's FM7), however, even at its current stage of
development, it is quite useable and recreates the sound of the DX7
with greater accuracy than any previous open-source emulation (that
the author is aware of....) It can easily load most of the thousands
of DX7 patch bank files available on the Internet, and can accept
patch editing commands via MIDI sys-ex messages from your favorite
DX7 editor/librarian.

hexter operates as a plugin for the DSSI Soft Synth Interface.  DSSI
is a plugin API for software instruments (soft synths) with user
interfaces, permitting them to be hosted in-process by Linux audio
applications. More information on DSSI can be found at:


The latest hexter version (currently 0.5.7) can be obtained at:


hexter requires a working DSSI host, liblo, GTK+ 1.2.x, plus the
ALSA headers and LADSPA SDK.

hexter is written by Sean Bolton, and copyright (c)2004 under the
GNU General Public License, version 2 or later.  hexter benefited
greatly from previous open-source efforts, most notably Juan
Linietsky's rx-saturno, and FluidSynth by Peter Hanappe, et al.
