Sources for USB-MIDI cables? And how many would I need?

by david

I'm trying to track down such things, but nobody locally even seems to have heard of MIDI, let alone USB-MIDI ... Also, how many would I need? My one external MIDI device is a Yamaha PSR-225GM keyboard, with what looks like the usual MIDI IN, OUT and THROUGH ports. I also have occasional access to a Yamaha PSR-740, which has additional programmable controllers. It has a similar collection of MIDI ports. I'd like to set things up so I could input from the keyboard(s) and also output to the keyboards. -- David gnome(a)hawaii.rr.com authenticity, honesty, community

I love your beats. Just listened to Meteors versus Dinosaurs. Have you got more? Overall, the track wasn't quite right for me - not easy enough to listen to - but I'm guessing that i'd love your more restrained stuff if you have any. James

by Nedko Arnaudov

jack_mixer version 6 "Dance of the headless corpse" released. jack_mixer is GTK (2.x) JACK audio mixer with look similar to it`s hardware counterparts. It has lot of useful features, apart from being able to mix multiple JACK audio streams. Changes since version 5: * Fix building against jack 0.102.20 * Handle python prefix different from install prefix * Fix LASH-less operation * Update install instructions after lash-0.5.3 and phat-0.4.1 releases * Apply Markus patch (thanks!) for sr #1698 (can't restore session using LASH) Homepage with screenshots: http://home.gna.org/jackmixer/ Download: http://download.gna.org/jackmixer/ -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

JACK sample browser?

by Nathaniel Virgo

Hi List, Recently I've been using SuperCollider a lot but one problem I'm having is that it's hard to audition samples while JACK is running. I was wondering if there's a graphical JACK app with a file browser which allows one to easily hear samples (preferably just by clicking once on them) and to copy their path (so I can then paste it into SuperCollider if I want to use that sample). I'm guessing these features are likely to appear in the open file dialogue of something like a simple sample editor, but it seemed easier to ask the list than to go through every such application and see if it has the ability to quickly audition samples (I don't want to have to load each one into the sample editor first as I want to be able to quickly compare several samples - I'm looking for a file dialogue with a "play" function that doesn't close the dialogue). IIRC Ardour can do this but it seems a bit of a heavyweight app just to audition samples. Or alternatively, if there's a little command-line jack sample player (like aplay except that it can be used while JACK is running) I could use that instead. Thanks in advance, Nathaniel

[ANN] a2jmidid - first release (resend)

by Nedko Arnaudov

I'm resending this mail (something is very wrong somewhere). Sorry if anybody got a duplicate. a2jmidid is daemon for exposing legacy ALSA sequencer applications in JACK MIDI system. It is based on jack-alsamidi-0.5 (jackd alsa seq midi backend) by Dmitry Baikov. The main purpose is to ease usage of legacy, not JACK-ified apps, in JACK MIDI enabled systems. It is tested, and works, here, with current SVN jack. ATM it may or may not work with other variants. Planned features/improvements: * One JACK client per ALSA sequencer client * Improved build system (autotools) and support (better handling) for other JACK variants (older MIDI API variants, jackdmp) * More control on what ports to bridge (currently bridging is fixed to non-hardware ports). * Real daemonization with log file, init.d script, etc. If someone wants to contribute please, contact me, or send patches, or request inclusion (Gna! a2jmidid project). As usual, packagers are more than welcome too. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Sound card identity crisis

by Steven Walker

This is probably something easy, but it's got me stumped. I'm running 64Studio (32-bit i386 version), M-Audio Delta44 and internal AC'97 soundcards. I want to use the Delta44, but the two cards seem to pick their ALSA assignments at random - one time the Delta44 will be hw:0 and the AC'97 will be hw:1, and the next time I start up they'll be reversed. Any suggestions as to how to make them each pick an assignment and stay with it? Thanks, Steve

For this exact situation I just configured my file manager (Worker) to play a selected file with mplayer when I press ctrl-m. -- Renick Bell http://the3rd2nd.com -- Renick Bell http://the3rd2nd.com

(no subject)

by Michael Nelson

Hi all, I haven't posted here for some time now. I've been busy at work, but finally, I have a linux box together that works again... It's a long story. Still, I have a problem. When I started jack on the first lone soundcard, it worked fine. However, I've added a second card, and now I'm having problems starting jack on either of them. The machine is an Athlon64 3200 on an nForce4 board. I'm running an up-to-date Planet CCRMA on Fedora Core 6. The first soundcard (that did work in this machine) is an RME DIGI9636, and the second is an RME 96/8 PAD. Both cards are second-hand, but I have seen each of them working before - the DIGI9636 was used previously with FC3 a year ago, and the 96/8 PAD was working in a Windows machine earlier today. I'm using qjackctl. Here is an excerpt of the messages as I attempt to start jack on the DIGI9636: ***** 04:01:22.393 JACK is starting... 04:01:22.393 jackd -R -dalsa -r48000 -p1024 -n2 -D -Chw:0,0 -Phw:0,0 -i2 -o2 04:01:22.395 JACK was started with PID=3488 (0xda0). jackd 0.103.0 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver ..
