[linux-audio-user] Sound application feature idea

by Drucer Ninetynine

I'm not a programmer myself, but I had an idea. Would it be possible (even in theory) to create an application that could analyze just a regular .wav song file and be able to "extract" the drum beats to a midi file? __________________________________________________ Do You Yahoo!?

[linux-audio-user] Midi keyboard problems with Ensoniq (ens1371) card

by Nigel Henry

My midi keyboard (Evolution MK-225C) works fine when using the USB connection with my Audigy2 soundblaster card. Someone on the Fedora list is having a problem with using the midi/gameport for his keyboard with an Ensoniq (ens1371) card. I tried the keyboard on my other machine that has an Ensoniq card. First using the USB connection, which works ok, and secondly using the midi cable which connects to the soundcards gameport. Big problems here. Qjackctl shows in it's midi connections, a midi plug followed by 64:ES1371-Rawmidi 0. Connecting this to ZynAddSubFx produces no output. I then installed kmidimon from planetccrma. when I connect kmidimon through qjackctl's midi connections I get 2 instances of. 5003 0:1 ALSA Port subscribed 64:0 130:0 If I then play a few notes on the keyboard, and then switch the keyboard off with it's power switch, I get on kmidimon. 64:0 Note off 1 0 0 So there seems to be some sort of connectivety between the keyboard and the machine by the midi connection. I freely admit that I'm not clued up on midi, but this keyboard has allways worked ok using the USB connection, but is having problems when using the midi cable through the gameport of the Ensoniq card. Any suggestions very welcome. Nigel.

[linux-audio-user] RME multiface gain, matrix and/or asoundrc and an array of confusion.

by we are

hey there crew. just wondering if there is someone out there that could enlighten me to the ways of the RME multiface. i have been using it for a few months now. i thought that these question would arrive in time, alas, i am still confused. for starters, i have been using peter todd artical in linux journal. some of this is useful but other bits simply don't help at all. my main problem is the gain settings. i can't seem to have consistant gain for different applications. my input gain is really realy low for the line (analog) inputs and i can't seem to find a way to boost them. when i record in ardour, the waveform is really small and i end up having to normalize every clip/track to get a decent volume. this is the same issue with PD. when i try to boost the gain on using the command as written by peter todd i get errors. ie amixer -c 1 cset name=Chn,index=1 32768 amixer: Cannot find the given element from control hw:1 the other issue is that when i use media players like audacious, xmms, mplayer etc. the output gain is a huge amount louder than PD and Ardour and other such audio apps. this is really confusing. as for routing the I/O's for live audio usage. i can't seem to workout a simple and effective way to route the sound for performance. ideally i would like to be able to have pd own the card. at the moment all the inputs are directed routed and mixed to the subsequent output ie analog in 1 goes to analog out 1, ananlog in 2 goes to analog out 2. what would be great is a matrix like the one in windoes...... any help would be awesome. thanks as always. tom

[linux-audio-user] Re: Novation Speedio

by Stefano Barbi

>Dear all, >Just want to bring this issue back before the list again. >Has anyone successfully used the Novation Speedio (a USB >audio/MIDI interface) with Linux? The MIDI side of mine >works fine, but the audio (both input and output) sounds >weird, like it's underwater, and the music plays too slowly >and at a low pitch. I'm running Gentoo, 2.6.13 kernel, >ALSA 1.0.8, JACK 0.99.0-r1. I got almost the same results with the Novation Speedio, except that recording works fine for me. I'm currently using a Gentoo 2.6.17-gentoo-r4 kernel and ALSA 1.0.12. I tried other kernel/alsa-driver combinations but I had the same problem. I also would like to hear if anybody has had better experiences with Speedio hardware. Thank you in advance. Stefano

[linux-audio-user] Canorus 0.0.2 released

by Reinhard

Hi, Canorus, the successor to the music score editor NoteEdit is looking for developers wanting to join the project. The project is hosted on berlios and provides SVN access to the sources as well as a Wiki for project discussions. I put out a first release based on the current SVN. You can fetch it from http://prdownload.berlios.de/canorus/canorus-0.0.2.tar.bz2. Homepage: http://canorus.berlios.de Wiki: http://canorus.berlios.de/wiki/index.php/Main_Page Contact: http://canorus.berlios.de/contact.html Canorus is the next generation music score editor (multiple viewports of the same score, scripting support, score source view, fast and intuitive UI, free software and cross-platform) . Technically it is based on Qt4, uses CMake as project management tool, swig for scripting / macros integration (primary script languages are ruby and python) and the cross platform rtmidi library for the MIDI playback. Canorus is searching for developers with experience in the fields C++, Ruby, Qt4, XML, Parsing, User Interfaces, Music Composition and Theory, Translators, Score Editing Unit Tests. Some of the tasks are: - Add several UI parts (either via Ruby or in the core) like Settings, several different property perspectives, Lyrics, Import / Export - Development of a robust test engine for the user interface and its core (could be done via scripting) - Import parsers for ABC Music, Lilypond, MusicXML, MUP (& NoteEdit), MusiXTeX, PMX, MIDI etc. - Export for several formats like the above - Recording and replay of macros - Multi-Level Undo/Redo (for different perspectives) If you want to join the project just mail me your berlios unix name (user name you use to log into berlios). I'd use that name for a wiki account too and will send you a password you should change as soon as possible. If you cannot code but still want to contribute read the forum message http://developer.berlios.de/forum/message.php?msg_id=31863 A big "thank you!" to everyone making this project possible. Best regards, Reinhard Katzmann -- Software-Engineer, Developer of User Interfaces Project: Canorus - the next generation music score editor - http://canorus.berlios.de GnuPG Public Key available on request
