Is there a way to play midi from a URL while it is downloading? timidity http://... doesn't, it waits until the entire file has downloaded before playing. pmidi only accepts a filename, not a url. Timidity++ and fluidsynth are able to act as servers that respond to midi events in realtime, but is there an easy way to hook this feature up to read events from a url stream while it is being downloaded? Thanks for any suggestions, -- Ryan Heise http://www.ryanheise.com/

[linux-audio-user] [LAM] a little livecoded a/v movie

by Dave Griffiths

hi all, a little movie of some of the livecoding I've been doing live lately (usually alongside slub[1]) http://www.pawfal.org/patterncascade/movies/rotblox.mpg the visuals and audio are both generated from the same improvised code (lsystem rules used in a similar way to the mondrian project[2]) more info: http://www.pawfal.org/patterncascade/ cheers, dave [1] http://www.slub.org/ [2] http://www.math.tu-berlin.de/~brinkman/software/mondrian/

Oops, I'm so sorry about that, I must have forgotten to test before releasing. New version is up: http://ccrma.stanford.edu/~kjetism/src/jack_capture-0.2.5.tar.gz

I think vstserver V0.0.1 or something ran everything in one process. But I changed it quickly because if one plugin crashed, the whole server went down as well, I'm not sure how bugfree v0.0.1 is though. It might still work...

by njcross＠sbcglobal.net

Is there a linux midi program that takes midi controller data and transform it to midi note data? Seems really simple? cheers, Nev.

[linux-audio-user] [ANN] jack_capture V0.2.4

by Kjetil S. Matheussen

jack_capture is a small program to capture whatever sound is going out to your speakers into a file without every having to patch jack connections, fiddle around with fileformats, or set options on the argument line. This is the program I always wanted to have for jack, but no one made. So here it is. http://ccrma.stanford.edu/~kjetil/src/ Changes 0.2.3 -> 0.2.4: *Give message to stderr during recording (not only after) if any overruns occur. *Do not delete file after recording if any overruns have occured. (stupid jackreq code #$!@$) *Increased default buffer size from 0.5M to 2M.

Very, very cool. thanks! :) I'm working on other ways of visualising the note events but that seems to be the most successful so far, as it's the clearest. cheers, dave
