Thanks a lot! To understand fully what is happening I will have to learn about pygame events. But I have the Midi data available now and can just use it for further processing. Again, thanks for the quick and to the point help. -- Sent from: http://pygame-users.25799.x6.nabble.com/

Re: [pygame] pygame midi module
Hi, thanks for the report. If you feel like it, please file an issue at https://bitbucket.org/pygame/pygame It's in python and cython, so maybe you can even fix this issue yourself :) A few people have used it for projects(including me), and it's based on PortMidi which has also been used by numerous projects. So if you avoid the rough corners it's sort of usable :) cheers, On Mon, Jul 22, 2013 at 8:39 PM, Silver rockac...@gmail.com wrote: I was trying out the pygame.midi module in the python interpreter. It seems nice although it is a WIP (?). Just thought I'd let you know trying to create multiple output objects for the same output can cause a segfault. Specifically, when you re-init the module (pygame.midi.quit(); pygame.midi.init()) it doesnt remember that the output is already occupied. Is there anywhere I should report this?

I looked at the examples and created this working program (see program

What can I change in the program to avoid the

Re: [pygame] Getting midi events for midi files playing in pygame
Hi, you should be able to do it with pygame.midi with a fair bit of work. However pygame currently does not have any special midi timing code, so you'd have to write that yourself (or maybe someone else has written some). You'd also need to do the midi file parsing yourself. There's probably existing packages to do both though. There's the pygame.midi module, which can get input midi, and also output midi. There is also pygame.music.play which can play midi. On Wed, Oct 27, 2010 at 5:20 PM, Ivan DelSol sunspi...@gmail.com wrote: I'm writing a visualizer for midi in pygame. Currently, I play a midi file in one program and get midi events in pygame via a virtual patch cable. I'd much rather play the midi file in pygame and receive the events, so that the user doesn't have to run a virtual patch program at the same time. Is that possible?

To make Pyrex compatible with C++ enumerations are no longer treated as integers, though assignment of an enumeration to an integer is still allowd. Not accepting an enumeration as a boolean value may be a bug. I would have to check. But then again it makes some sense.

Re: [pygame] controlled midi playback
I guess it is getting late. LIBCMT.LIB is one version of the VC 6.0 C library, so apparently isn't present in VC 7.1. I expect uuid.lib is still be available. I am not so sure about OLDNAMES.LIB, but then you did not mention a LNK1104 for it so I assume it is also available. So try replacing line 34 in setup.py with the following two lines: libraries = [portmidi, winmm, porttime], extra_link_args = [NODEFAULTLIB:LIBCMT]) If it the linker complains about an invalid argument try adding a forward slash / before NODEFAULTLIB. Lenard Lenard Lindstrom wrote: Python 2.5 extensions are compiled on Windows with vctoolkit2003 by default. It is the same compiler used on Python 2.5.

Maybe the VC linker can ignore -defaultlib directives in a library. I find there is a /NODEFAULTLIB:library linker option. Maybe add something like the following to setup.py after libraries = [] for win32: extra_link_args=[NODEFAULTLIB:LIBCMT, NODEFAULTLIB:OLDNAMES, NODEFAULTLIB:uuid.lib] Or try running vcvars32.bat (is there one for the 2003 toolkit) before executing setup.py. If you wish you may try the pypm.pyd I compiled MinGW. It links to msvcr71.dll, which is the big issue with Python 2.5, and works with my small test program.

[EMAIL PROTECTED] wrote: hi, i have a midi song (not polyphonic) and want to play back one note after another triggered by key presses. what would be the best way to do this? i guess i can't directly do this with pygame but i need some midi library? does anyone know which one would be suited for that (ideally it should work in linux and windows)? has anyone tried to do something similar? Check out the Python music page: http://wiki.python.org/moin/PythonInMusic Of the various midi packages PyPortMidi is still available. -- Lenard Lindstrom [EMAIL PROTECTED]
