+README.txt
+----------
+
+Graphical frontend and built-in softsynth (MusE Experimental Soft Synth) for MusE, based on Fluidsynth
+(http://www.fluidsynth.org).
+
+Features:
+---------
+- Loading/unloading of soundfonts
+- Easy control of fluidsynth's send effects and their parameters
+- Mapping of soundfonts to fluidsynth channels
+- Stores all settings in the current project file and automatically loads all effect parameters,
+ soundfonts, channel settings and presets when re-opening the project.
+- Makes it possible to use several soundfonts in one single fluidsynth instance (thereby reducing CPU usage since they share
+ the same send effects)
+
+
+Changelog/History
+-----------------
+040524
+- Err... Fount out that this changelog is neglected. See ../../Changelog.txt instead.
+031019
+- Bugfixes and changes in storing/retrieving init parameters (Mathias Lundgren)
+031009
+- Unloading of soundfonts works (Mathias Lundgren)
+- Last dir stored in project-file (Mathias Lundgren)
+- Ordinary controller-events enabled (Mathias Lundgren)
+031008
+- Mapping of soundfonts to fluidchannels and selection of patches implemented. (Mathias Lundgren)
+- Permanent storage of channels & patches. Extended GUI. (Mathias Lundgren)
+031002
+- Various communication problems fixed between GUI and client (Mathias Lundgren)
+- Storage of synth parameters and soundfonts enabled (Mathias Lundgren/Robert Jonsson)
+
+0309xx
+- Problem with loading of soundfonts resulting in Jack timeout fixed by moving loading of soundfonts to separate thread. (Robert Jonsson)
+
+Original code written by Robert Ham (no information about the history of his work)
+
+
+Known problems/TODO:
+--------------------------------------------------------------
+* Turning on the chorus and/or modifying chorus parameters locks the client.
+* Illegal chorus parameters can be sent to fluidsynth.
+* Drum patches (lbank=128) not implemented yet
