I've seen the lengthy discussion of NSM and decided I'd like to give it a whirl, but I cannot figure out where the code lives. As far as I can see http://non.tuxfamily.org/nsm/ has no mention of how to get the code. So how do I get (git?) it? Thanks

NSM - handling large files

by Emanuel Rumpf

The discussion started, with the question about large files. Keep it simple - store either files or links in the session folder ? Why not ? Some more opinions please. -- E.R.

Re: [LAD] midi and audio connections apps output

midi and audio connections apps output

by Louigi Verona

Hey guys! I was wondering if JACK, QJackCtl or Patchage or any other programs that manage audio and midi connections in JACK can output a list of connections they currently make in text format? The idea is that when scripting, you would use things like: jack_disconnect rakarrack-01:out_1 system:playback_1 jack_disconnect rakarrack-01:out_2 system:playback_2 jack_connect specimen:out_left rakarrack:in_1 jack_connect specimen:out_right rakarrack:in_2 It would be pretty cool if when using Patchage you could, for instance, ask it to output a similar connections list that you would copy and put in your script. I do notice though, that it probably would not output disconnect messages, but only connect ones. But this is still help. -- Louigi Verona http://www.louigiverona.ru/

Midi Channel routing with hardware?

by Nils

Hello list, tl;dr: Is there a cheap midi hardware that just gets midi information in and routes it out, except on a different, single, channel which I can change easily up and down directly on the hardware? Long version: Recently my master keyboard broke. It was just a cheap, used m-audio keystation 49e. I did not buy a new master-keyboard because I have a Roland HP207e digital piano here which is vastly superior when it comes to actual playing. Sadly not to control midi data. I have a Behringer BCF2000 here which I connected to my keyboard now, so I should be able to do something with it, but there is one thing missing: Channel Changes. Anybody who worked with Linuxsampler knows that channel switching is very important to switch instruments, while program changes are neglectable. So maybe there is a way to use my piano, which always sends on the first channel (except I dive into inaccessible menus) if a) I find a way to shortcut the "change channel" command, but I don't know how. It has midi in and a usb connector, but that is not used to control it, just to send and receive midi data. Incoming data gets interpreted like a sampler does. b) There is a way to use my BCF2000. I am very inexperienced with that thing. c) There is a cheap standalone hardware, just a "little box", I can plugin between my linux box and the piano, which re-routes the midi data, like I mentioned in the short version above. d) I build something myself, a small linux plug computer where I somehow attach two buttons (ch up and dow) and use the usb connections. At least the cables are cheaper :) But this is the most unrealistic method, although it might be the most interesting one. Maybe you know something? Nils P.S. I know I can do the channel routing directly on my linux computer, after receiving the data and before sending it to a sampler. But that is inconvenient.

c/jack question

by Egor Sanin

Pardon the newb question, but why does: a) this work --------------------------------------------- #include <jack/jack.h> jack_position_t pos; jack_transport_state_t state; jack_nframes_t frame; int process (jack_nframes_t nframes, void *arg) { state = jack_transport_query (client, &pos); frame = pos.frame; } --------------------------------------------- b) this segfaults --------------------------------------------- #include <jack/jack.h> jack_position_t *pos; jack_transport_state_t state; jack_nframes_t frame; int process (jack_nframes_t nframes, void *arg) { state = jack_transport_query (client, pos); frame = pos->frame; } Thanks

Laborejo Release 0.2 Announcement

by Nils

Exactly one month after the first release, here is Laborejo 0.2! Laborejo, Esperanto for "Workshop", is used to craft music through notation. It is a Lilypond GUI frontend, a MIDI creator and finally a tool collection to inspire and help you compose. It works by reducing music-redundancy and by seperating layout and data. The next release is scheduled for May, 8th. One month from now. Before you read the details make sure to connect to Laborejos Facebook, Twitter or Google Plus! https://www.facebook.com/Laborejo https://twitter.com/#!/Laborejo https://plus.google.com/b/116744898976321238325/ Screenshot (Laborejo and Lilypond, side by side): http://www.laborejo.org/images/screenshots/latestscreenshot.png This is the release of version 0.2 Download: https://github.com/nilsgey/Laborejo/tarball/0.2 Dependencies: http://www.laborejo.org/documentation Linux Instructions: Unpack, cd into the created directoy, execute: ./laborejo-qt.sh Then use the number- and cursor keys for immediate success! Check Help->Manual for navigational and note/rest entry keys. Everything else is in the menus. New since version 0.1: - Repeats, Alternate Ends and Jumps in various forms. The main Feature for this release. - Playback Trigger ("Only reduce volume in the second repeat" or "Mute track if python weather module reports rain") - Master Track (Merges with every other Track. Use to structure your piece, make global changes, change tempo etc.) - Various Commands like "Join Selection to Chord" and "Add Octave to Chord/Selection" - The usual bread&butter bugfixing and improving. Most important known problems: * This is Alpha Grade Software. Don't use for long-term work. However, the produced midis and PDFs will last forever. * There is no built-in jack midi output yet. You have to export midi files. * Documentation is nearly non-existent. Have fun, it would be nice to hear from you! Nils http://www.laborejo.org

[ANN] JAudioLibs v1.0.120123 (JNAJack Java<>JACK improvements)

by Neil C Smith

Hi All, JAudioLibs v1.0.120123 is now available from http://code.google.com/p/java-audio-utils There's only one major change in this release - the addition of JNAJack support for JNA's new CallbackThreadInitializer, which was specifically requested for JNAJack, and brings a big improvement in CPU usage. Use of JNA 3.4.0+ is now highly recommended, and JNAJack will emit a warning if an earlier version of JNA is detected (though it will still work). There are no API changes. Full release notes are available at http://code.google.com/p/java-audio-utils/wiki/ReleaseNotes As you may have guessed from the version number, this is actually the code from the January release of Praxis (http://code.google.com/p/praxis/). The delay in releasing separately was caused by a) the desire to test and b) a manic couple of months! ;-) Best wishes, Neil -- Neil C Smith Artist : Technologist : Adviser http://neilcsmith.net

ddptools 0.8.7a released

by Andreas Ruge

Hello everyone, I've released ddptools 0.8.7a, a set of command line programs to create, read and export audio from DDP images. This release fixes a potentially critical bug in the cue2ddp command and introduces some minor enhancements: * when verifying DDP checksums ddpinfo now searches the DDP directory for checksums files, it supports a variety of file formats and is known to woek with the checksums generated by md5sum, ExactFile, Pyramix/Gear, SADiE, Sequoia, Sonoris, Wave Editor, and DSP Quattro. * for OSX ddptools now now comes as three-way universal binary including i386, i86_64 and ppc (32bit) Details are found at http://ddp.andreasruge.de. Feedback and testing is very welcome! Best Andreas
