ZynAddSubFX: resynced with their Git repo

Browse Source 
ZynAddSubFX has gained some new developer power so development has been
going on well for quite a while now in their Git repo. It's time for
the first big resync so future changes can be integrated easily.
(cherry picked from commit 3c18e436cd)

Q2) How can I load files from older versions of ZynAddSubFX (like *.mas_zyn,etc)
A2) You need to convert them into new format. Please use 2.0.0pre1 or (recomanded) 2.0.0pre2 versions of ZynAddSubFX to load old file formants and save them in the new formats
A2) You need to convert them into new format. Please use 2.0.0pre1 or (recommended) 2.0.0pre2 versions of ZynAddSubFX to load old file formants and save them in the new formats
Q3) How can I change the number of parts, voices to ADSynth, effects, etc. ?
A3) Look in src/globals.h and change there theese values. You don't have to change anything else, just recompile all. But most settings must be below 128. As the rule of the thumb if a setting is 128 or below 128, please don't make it bigger than 128. Anyway, I don't belive that you'll need more than 128 for theese settings; for example you don't need 128(or more) effects same time? That's why I put the limit of 128 (using 7 bits of char).

Q4) How do I enable Jack support on ZynAddSubFX ?
A4) Look in "Makefile.inc" from "src/" directory for more information. It is highly recomanded that the Jack samplerate to be equal to ZynAddSubFX samplerate (SAMPLE_RATE from globals.h), otherwise the resampling will be done and this will decrease the quality a bit.

@@ -1,3 +1,16 @@
2.4.0 (21 Jun 2009)
- extended mono functionality
- legato mode
- export functionality on PADsynth
- inclusion of LASH client
- inclusion of DSSI audio output
- enabled tooltips for knobs (both description and value tooltips)
- added support for newer JACK api
- added quertz support for virtual keyboard
- started to encorperate cxxtest for unit testing
- many bugfixes
- code cleanup
2.2.1 (28 Apr 2005)
- made to work with mxml-2.2 (will NOT work on older versions)
- it is possible to remove completely the graphical user interface (e.g. it can run without X). For this you need to modify the DISABLE_GUI option from the Makefile.inc
