Audio software website: own forum or extern?

by Nils

Hello, I am currently creating the website for my soon to be released gpl notation editor. I can't decide if the site should offer user accounts for a forum or bug tracker or if I should try to get a subforum at linuxmusicians or kvr etc. (Heck, even facebook) >From one perspective it is good to have user accounts myself, especially if anything like bug-reporter-highscore or donations happen and I want to keep track to give rewards. But on the other hand it is annoying for the user to create and manage a new account for each little page in the web only to ask one question. It would be nice to use an existing account in an infrastructure you already know and hang around. What do you think? Nils

midi+jack+musescore

by Rustom Mody

I recently got a yamaha UX16 midi-to-usb bridge. With nted (which is not jackified) it works ie I can have nted play a piece into my keyboard. Likewise I can play the keyboard into nted and the notes get entered. Now I want to do the same for musescore which is jackfied but cant figure out how to do so. This is how my qjackctl shows: Audio tab shows mscore (readable) connected to system (writeable) [Also has a system readable connected to nothing] Midi tab shows mscore readable and NOTHING writeable Alsa tab shows midi through and UX16 readable midi through, UX16 and timidity writeable. So the problem is that if I could see UX16 and mscore in the same tab I'd connect them but UX16 only occurs in ALSA tab and mscore in midi and audio tabs but not in alsa. So how to connect 'across tabs?'

Working with multiple scales simultaneously - user POV

by James Morris

Hi, I'm just wondering how you would rate the importance of program which dynamically assigns pitch and velocity to incoming events to be able to work with multiple key/scale simultaneously? It's a bit of an experiment but I'm thinking it might be useful in live situations for the electronic/dance/glitch/etc orientated musician, but it might also happen to work out as a fun/toy program for people play|learn-ing about music and scales (possibly). Would anyone consider output of notes in multiple scales important in either of these situations? Thanks, James.

ladspa effects hardware controller

by James Miller

Hi - I'm hoping to use my laptop with ubuntu studio to play realtime live at a gig. I am wondering if there is any way to connect a midi controller of any kind (preferably something foot controlled as I am a guitarist) so that I can control the fx. I am a developer so if you know if ladspa or jack rack exposes a midi control interface then that would help, or even a serial interface. Thanks, James -- James Stewart Miller Bsc(hons) Psych.

[OT]: Publish music also in OGG format please?

by Lorenzo Sutton

May I kindly and humbly suggest that people posting on LAU as links to 'straight' mp3 files also provide a link to a file in OGG format? IMHO it makes sense given the nature of the list and the better experience for readers/listeners and it only really takes very little effort [1] Lorenzo. [1] Example using oggenc (in the vorbis-tools package on debian-based distros). If you have the original wave file (better): oggenc -q 9 my_file.wav #will create my_file.ogg use -o option to save to another file. See man oggenc for many more options If you only have an mp3 version (also requires lame): FILE=my_file; lame --decode $FILE.mp3 /tmp/$FILE.wav && oggenc -q 9 /tmp/$FILE.wav -o ./$FILE.ogg # replace my_file at the beginning with the filename of the mp3 file withut extension # could be done without the temporary wave file through raw pipes but one must know sampling rate, bitrate and channels of the file

keeping busy: new sounds from DLP

by Dave Phillips

Greetings, I've been exploiting the advantage of not having to keep up with deadlines. Another Freesound excursion : http://soundcloud.com/davephillips69/freesoundscape-2 Created with AVSynthesis/Csound : http://soundcloud.com/davephillips69/first-lament-of-the-cello http://soundcloud.com/davephillips69/when-morty-met-hildy-and-me A piece made with SuperCollider3 and FScape : http://soundcloud.com/davephillips69/mere-stone-and-oak All pieces mixed and produced in Ardour3. Downloads from SoundCloud have been activated, but for the unClouded I'll prepare MP3/OGG files for downloading from linux-sound.org. Best, dp

Polyphonic Pitch Estimation

by Gerald Mwangi

Hi all, I'm developing a small app which uses aubio to extract the fundamental Frequency of a monophonic guitarsignal to drive a set of wavetable synths. It works quite well and I'll put up on the net when I have the time. But I would like to extract the fundamentals of a polyphonic signal. Does anyone know of a lib which does this in realtime? Or at least a state of the art paper I could implement? thanx, Gerald

Monophonic Audio to real time midi?

by Nils

Hello, is there a tool that allows audio-in over jack and gives me jack or midi alsa out? I need (near) real time monophonic conversion so I can use it for step entry in midi-in programs. Nils

Same story as the Pure Data solution - not exactly 'out of the box'. But SC supports Jack and ALSA as well.
