Here is what you can test today:

   * if Csound is built with 64 bit floats, opcode libraries are
     searched in OPCODEDIR64 (if OPCODEDIR64 is not defined,
     or MYFLT is float, OPCODEDIR is used instead).
   * changes to command line parsing. Options are now read in
     this order (the last one has the highest precedence):
       1. .csoundrc in HOME directory or defined in CSOUNDRC
       2. .csoundrc in current directory
       3.  in CSD file
       4. command line options
   * removed some annoying warning and error messages related
     to sound file format options (e.g. output file cannot be
     both WAVE and AIFF etc.). The option specified last will
     simply override earlier options.
   * --opcode-lib options specified in multiple places (.csoundrc,
     command line, etc.) are concatenated, and all libraries are
     loaded. Redundant library files are only loaded once (this
     may not work on all platforms, see below).
   * -Q MIDI output under Linux now takes a string argument
     (such as /dev/snd/midiC1D0) instead of a device number.
   * cleaned up listing of short options in argdecode.c (replaced
     multiple redundant lists with a single one)
   * attempts at fixing return from -z/-z1 and utilities (the
     latter are not very consistent regarding return values, so
     more fixes are needed in this area)

Of course, it is not unlikely that bugs were introduced, particularly
in parsing command line options. Also, the changes in the library
loading code assume the following behavior of csoundOpenLibrary()
and csoundCloseLibrary(): if the same library is opened multiple times,
the same handle will be returned, and the number of CloseLibrary calls
must match the number of OpenLibrary calls in order to actually unload
the library from memory. This is true of unix-like systems but I am not
sure about Windows and Mac platforms.

Forgot to mention this one:

   * on systems other than WIN32 and mills_macintosh, all messages
     are printed to stderr instead of stdout, for -o stdout to work
     correctly.

This is for csound 5,
tested on winXP.

There's still a problem loading stereo files with GEN 01.
Mono files work fine.

Gen 01 loads a stereo file, but prints to the console that it's reading channel 1 only.
The resulting sound is somwhat like if the sound files had been ring modulated with a square wave.

example csd, and console print below

Would it not be possible for it to do both?

I do not think it would be trivial; the current code simply writes
to the selected file in non-blocking mode (this may allow for
output to a pipe/fifo or stdout), and files do not have index numbers.
It might be possible to restore the original version that used
the OSS /dev/sequencer, and query the device names, but I am not
very familiar with the OSS sequencer interface. Finally, the
ALSA API could be used, but that is not quite as simple as just
writing to device files.

there's a bug that appears when using the zak space reading and writing at init rate.

using ziw in an instrument even prevents the rest of the instrument's code to run.

I do not know if this is a bug in ziw/zir or if it is a more general initialization bug.

a simple csd showing the bug is attached

hello,

I'm using python to pipe line events to Csound,
at the same time, I'd like to use midi to control csound.
I've set it up so that Csound is loaded as a module inside Python,
and the csound command line (inside the python script) opens a hardware midi input.
This way, I was hoping, midi does not pass through python, but goes directly from hardware midi input to csound.

This works, but python will not quit.
I have to kill the python process in the task manager.
Using WinXP.
I've attached a py file used for testing.

If this is a "legal" way of setting it up,
it would be very nice if it could exit gracefully.

I have committed changes that may fix this problem.
