Changes in version 5.02:
2006-06-04 Michael Gogins <[EMAIL PROTECTED]>
* Changed the MIDI interoperability opcodes (OOps/midiinterop.c)
midinoteoncps, midinoteonoct, midinoteonpch to leave key and
velocity unchanged for score-driven performance.
2006-06-04 Istvan Varga <[EMAIL PROTECTED]>
* Engine/otran.c:
work around constndx() not being compiled correctly

9 (doubles)
* Engine/entry1.c, H/sndinfUG.h, OOps/sndinfUG.c:

defaults to 1, and if zero, will make the opcodes return zero on
headerless files rather than some possibly incorrect defaults

* Made it possible to control the behavior of the FLTK plugin
from the host application. This can be done with the following
code between calling csoundPreCompile() and csoundCompile():
CSOUND *csound;
...
csoundCreateGlobalVariable(csound, "FLTK_Flags", sizeof(int));
*((int*) csoundQueryGlobalVariable(csound, "FLTK_Flags")) = flags;
where 'flags' can be the sum of any of the following values:
1: disable widget opcodes
2: disable FLTK graphs
4: disable the use of a separate thread for widget opcodes
8: disable the use of Fl::lock() and Fl::unlock()
16: disable the use of Fl::awake()
additionally, after calling csoundCompile(), the same variable
can be checked to find out if graphs or widget opcodes are used:
32: FLrun opcode was called
64: callbacks for FLTK graphs are set
* Top/main.c:
fixed crash on registering opcodes from the host application
* frontends/fltk_gui:
new GUI frontend that uses the Csound 5 API and FLTK

2006-04-17 John ffitch <[EMAIL PROTECTED]>
* Opcodes/bilbar.c: Added prepared piano string model
* H/entry1.h:
* Engine/entry1.c: Added remove opcode. Probably should be an API
function rather than opcode
* Engine/insert.c (delete_instr): New code to delete non-active
instruments. Still needs to be checked as it may leave structures
dangling.
2006-04-15 Istvan Varga <[EMAIL PROTECTED]>
* Engine/namedins.c, Engine/otran.c:
optimizations in orchestra parser
* interfaces/lua_interface.i:
wrap cs_glue.hpp and csPerfThread.hpp
2006-04-09 Istvan Varga <[EMAIL PROTECTED]>
* Engine/envvar.c:

sf_open() in this case if sf_open_fd() fails
* InOut/FL_graph.cpp:
wait for the window to be closed by the user at end of performance
* InOut/libsnd.c:
fixes in enabling peak chunks and dithering
* InOut/libsnd_u.c:
type2string(): added SD2 to file types

print warning if the buffer size (-b) is not an integer multiple
of ksmps in full-duplex mode
* InOut/window.c:
moved deferred loading of widgets plugin from main.c to make graphs
work in utilities
* Opcodes/compress.c:
made rms levels relative to 0dBFS in distort opcode

added dispinit() function pointer to CSOUND structure,
for use by utilities
* H/version.h:
updated API version to 1.01 to reflect change to CSOUND structure
* util/pvanal.c:
implemented graph displays (limited to 30 frames at this time)
* util/sndinfo.c:
clear SF_INFO structure before calling sf_open()
2006-04-08 Istvan Varga <[EMAIL PROTECTED]>

fixed a few minor errors
2006-04-04 Michael Gogins <[EMAIL PROTECTED]>
* Changed FluidSynth opcodes slightly, with
fluidEngine iChorusOn, iReverbOn
pfields, defaulting to "on"; this can reduce noise in low frequencies
in SoundFont rendering.
* Updated Windows FluidSynth opcodes to use latest FluidSynth sources.
2006-03-28 jpff <[EMAIL PROTECTED]>

* interfaces/cs_glue.hpp:
- added new classes to wrap MIDI I/O:
CsoundMidiInputStream sends MIDI input messages
CsoundMidiOutputStream polls MIDI output messages
- added MIDI I/O callbacks to CsoundCallbackWrapper
- made it possible to use the message buffer in multiple threads,
to allow for redirecting the message output of a
CsoundPerformanceThread
2006-03-21 Istvan Varga <[EMAIL PROTECTED]>
* SConstruct, Makefile-win32:
renamed Csound library to csound{32,64}.dll.5.1 on Windows
* SConstruct:
attempts to fix install target (still needs a lot of work)
* Engine/namedins.c, OOps/bus.c:
fixed a-rate channel allocation in user defined opcode with
local ksmps
* Engine/linevent.c:
various minor fixes and code improvements
