[linux-audio-user] two alsa/jack questions

by Atte André Jensen

Hi I'd like to be able to restore a complex scenario of multiple softsynths running and midi and audio routed between them and baybe a sequencer and some jack fx. Is there a best way to do this? If not I imagined just writing a bash script for each song that starts and connects everything. I know and use aconnect from bash. I also managed to have my hardware showup at the same alsa client number, but it seems that whatever synth I start first it shows up as client 129. Can this be fixated or should I poke in /proc/ to find what's where. Same with jack, although here I don't know what to supply for src_port and dest_port for jack_connect (I guess that's what I'll be using). Thanks in advance for any help... -- Peace, love & harmony Atte http://www.atte.dk

Otherwise it's a bug. This file only has commented lines of documentation. So to set this up in this manner I would need to add a line for "realtime" or such for UID=29 (audio). audio <hard|soft> realtime ?? realtime is not listed as one of the items. There in an mlock <memlock> associated with it in its startup script.

Re: [linux-audio-user] alsa midi processor again

Edit the paths at the top of the file "make_qmidiroute" to fit your installation and compile it using this command: $ make -f make_qmidiroute There is not a target to install the program, simply copy qmidiroute to your /usr/local/bin directory.

by Rui Nuno Capela

Hi, Just to let you know and leave me with some peace of mind for the coming summer holidays, here's what: QjackCtl 0.2.18 has been released, where a couple of sloppy bugs have been fixed. Taken from the rather minimal changelog for this one: - A freezing and endless loop condition on the patchbay socket item duplication (copy) has been fixed. - Fixed output disability when messages limit option is turned off (thanks again to Wolfgang Woehl for spotting this one). Right. You can grab it from the usual original place(s): http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-user] Re: Music

by Gavin Stevens

Hi Steve, I really like this piece - I've listened to it quite a few times. Do you have a score or midi file available? I'd like to play it myself - I'm always looking for new pieces for piano recitals & other concerts. I am currently working on some new piano pieces myself, mostly freely composed, apart from a project I'm involved with at the CN Fractal Music Forum at Yahoo Groups. I shall be recording a lot of piano music as soon as time permits.
