PianoBooster version 0.5.0 has just been released

by Louis B.

PianoBooster version 0.5.0 has just been released, this is the first ever release of PianoBooster. If you dabble in music and have a Midi Piano keyboard lying around then give PianoBooster a go as it actually makes sight reading music fun!!!!! To see what it is all about take a look at the screen shot: http://pianobooster.sourceforge.net/images/LinuxScreenShot.png First choose a MIDI file (the Easy Play Beethoven is a good one -- see the download page for where this can be found) then select which part that you want to play along with (e.g. the piano part or the strings part etc). Then select the "left" hand or the "right" hand or if you are feeling really brave choose "both hands" and try to play along. The "Follow You" mode make it really easy to sight read the scrolling notes as the whole accompaniment will stop and wait for you to find and play the right notes. The accuracy bar monitors how well you are playing. If you are skilled enough the accuracy bar will go right to the end and then turn blue. But every time you are too slow or playing out of time, then the accuracy bar slips back a bit. You can watch a video of it in action on YouTube: http://uk.youtube.com/watch?v=7YaDllVreuM Piano Booster 0.5.0 is released under the GPL and is available at SourceForge on this page: http://pianobooster.sourceforge.net/download.html L o u i s B a r m a n

korg + timidity + rosegarden via jack

by robert lazarski

Hi all, I have the latest rosegarden (RG) connected to my korg oasys via a midisport 2x2 just fine. However, RG doesn't have a piano roll UI like timidity does - which I use to learn complex piano pieces that don't have sheet music, My goal: route the midi out of RG to both my korg and timidity simultaneously. Is that possible? I'm a jack newbie, but via QJackCtl I was able to take this screenshot showing my alsa connections: http://braziloutsource.com/random/jack_alsa.png http://braziloutsource.com/random/jack_audio.png The "midi" pane in the connections window is blank. I started timidity with "-Oj" , but don't hava timidity in the alsa pane. Here's a scrrenshot of my options to add an output socket: http://braziloutsource.com/random/jack_output_socket.png Any ideas? Robert

[ANN] zynjacku version 2 released

by Nedko Arnaudov

In this release: * zynjacku codebase updated to the latest state of LV2 art. Especially, event MIDI port synths are now supported. * The tarball now contains lv2rack - a host for LV2 effect plugins. * Saving/restoring of presets. Does not work for dynparam plugins yet. * LASH support (autodetected at runtime). * Lot of general fixes that should make zynjacku more usable. I would like to thank Krzysztof Foltman for adding support for some LV2 extensions and Martin Raspaud for helping with slv2 compatibility during my LADI quest. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins. You need slv2 library, Pyhton bindings for PATH and lv2dynparam host library to compile zynjacku tarball. Project homepage with screenshots: http://home.gna.org/zynjacku/ Get tarball from here: https://gna.org/files/?group=zynjacku -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Survey: Linux users and music performance

by John Littler

Hi, For a while I've been wondering just how many people are using Linux for music performance, and what kind of music. This led me to the idea of doing a survey on this list to see what we come up with. The results will be published on Mstation.org Please email your replies to me. Here we go ... artist name: website: Linux distro and addons: gear setup: music genre (roughly): types of venue played: link to an example track: comments on your setup (how happy you are with it; improvements you're thinking of etc.): anything you think is important that hasn't been asked: Thanks very much. Replies could provide people with a clear pathway as to how they could proceed. cheers John -- http://mstation.org an e-zine

The Drummer's Jigsaw.

by Philippe Hezaine

Hi all, Here is a second draft which include BLUES-patterns. http://philippe.hezaine.free.fr/spip.php?article36 It's almost like the old Drummer's Free Art except for some update. Be aware there are not velocities in the file yet. This draft is for those amongst yours who can't wait (as for me sometimes). So you can choose and copy and paste from the file to the template and try new patterns. You have to install Lilypond. If you want the velocities read the advices from Dominic Sacré in the thread: "transform midi Control Change 7 into velocity events?" on this list. You have to install mididings. Have fun. -- Phil.

Re: [LAU] no connection...

I attached a screenshot of my > desktop and setup. Preston, I have to admit I am having some trouble here myself which I could not yet solve reliably, that is why I respond so late... It might have to do with the sound device that is selected in kmix (I wrote about that issue some other day a while ago). There are several variables/applications involved that want examination so I guess it will take me some time until I can give further details on that. The problem that I have is that like You I cannot receive MIDI data from an external USB device, but in this case kmon showed me that sometimes there is a short number of MIDI messages I get and then it all stops and I do not see any more messages, and sometimes I get no MIDI messages at all. As I said a while ago I wrote about this problem and noticed that it could have to do with the sound device to which kmix is set to. When You run kmix (open it from the task bar) and You have several sound devices for sound output then kmix offers a popup menu from which to choose which one You want to adjust. I have noticed that I get these hangups when the internal onboard sound of my notebook is selected here, and it is all just fine when the USB sound device is selected, but now I am not so sure here anymore. I also had some problems to get qjackctl running properly when there are several sound devices available. It seemed the problem could be fixed when setting qjackctl to output do "default" device and input from "default" device and apart from that set the sound device with the single menu at the top menu called "interface". But still I have problems with that and get no MIDI data, so I have to have a closer look at what is happening here. BTW, do You have no MIDI data even when not running a RT kernel? It could also be a kernel related problem, as I had no problems with an older RT kernel. Possible solutions for me: Run jackd via command line (only), so I can see exactly what jackd gets when run. Regards, Crypto.
