[linux-audio-user] Re: [Rosegarden-user] Transport / sequencer misbehaviour

by Alejandro Lopez

Thanks for your help. I'm very new to all this technology and I'm lost as to where to start my investigation from. Should I look at my MIDI connections by listing them somehow, and see if there's something suspicious there? What would be a sensible procedure to follow? Many thanks.

RE: [linux-audio-user] WMA

by Alejandro Lopez

Just found about ffmpeg, http://ffmpeg.sourceforge.net/index.php and other tools by reading about WMA at Wikipedia, http://en.wikipedia.org/wiki/Windows_Media_Audio so it looks like I'm on the right track to solve this already. Sorry guys I should have done the healthy exercise of "Searching The Fine Web" prior to my posting :-( Cheers, Alex >Hi, > >This post reminds me I need to burn an audio CD from a set of .WMA files >I've been given :-((( So far, the only thing I've been able to do with >these is playing them with Windows Media Player (and putting them in an >audio tape, remember those?). > >I absolutely fail to understand why, if I have some codec installed (and I >have since I can play the files), I still can't do a file conversion to a >raw waveform I could then use to burn the audio CD.

[linux-audio-user] Rosegarden transport / sequencer misbehaviour

by Alejandro Lopez

Hi All, Been taking my first stepts with Rosegarden. So far, I'm very impressed with its usability for the fews tasks I've attepted so far. The program is generating MIDI messages correctly. For instance, if I open a pianoroll and click on a piano key on the left, sound is produced. However, when I click on the "play" transport, the blue cursor which shows your current time position dissapears, I get lots of complaints from the sequencer at once (one per MIDI event I suspect) on the console (having to do with timing of the MIDI events, will post them on Monday if relevant), and no sound comes out. Sometimes, if I click on the rewind button just after that, the blue cursor goes to the start of the song and the song starts to play correctly (with the cursor being updated, moving to the right that is). Once it's playing I can rewind or move the cursor (while playing) correctly, so it's a kind of "startup problem". I can do this a few times (stop and play again) but after those, it won't start anymore no matter what I try on the transport. Also, whenever I've managed to get it playing it has been with test files a couple of bars long and with a couple of MIDI tracks only. If I load a full song in the form of a MIDI file, I get many more complaints when I hit play and can't make it sound at all. It looks like Rosegarden is failing to control it's builtin sequencer, specifically I get the same behaviour when I route my MIDI notes to Timidity (working as a soft synth) and also when I route them to a external MIDI connector. Whatever it is, it looks like it has to do with the sequence, not the individual MIDI messages (musical notes and so on). I was wondering if there may be a way to somehow instruct Rosegarden to use Timidity's sequencer for this task, the reason being that when I've used Timidity as a MIDI player from the command line, it worked very nicely. Does this sound familiar to any? Thanks to All. Cheers, Alex _________________________________________________________________ Express yourself instantly with MSN Messenger!

[linux-audio-user] How broken are epia boards for use with ardour? (sorry if you've seen this message many times)

by geekery＠jamesfenn.co.uk

Hello there, I am thinking about putting together a silent (or very near) machine for recording classical guitar. I have this set up in mind and would like to use ardour (so that I can do drop-ins etc) even though there is a don't use epia warning on the ardour homepage: epia m10k with a replacement fan (17db) silverstone LG06 (silent PSU - fanless) samsung spinpoint (apparently the quietest Hard Drive about) 512Mb ram ...and my trusty Terratec EWX2496 The main question is: I would only at maximum be multitracking 2 parts. Is the epia so bad that it wouldn't be able to cope with that? (I have no idea what the link about the epia on the ardour homepage is talking about so please have mercy in your replies.) Otherwise, does anyone have any alternative suggestions about putting together a good-as-silent machine for only a little cash? (this set-up with a DVD burner will set me back around 350 pounds sterling not including the soundcard.) Much thanks for your interest, James Fenn

RE: [linux-audio-user] How broken are epia boards for use with ardour?(sorry if you've seen this message many times)

by Alejandro Lopez

Hi James, The setup I'm planning, which is rather affordable, is a normal noisy desktop PC (CPU only with no screen, keyboard or mouse), LAN connected to a cheap laptop which would act as the console. The advantages I expect this setup to bring are: -I can take the noisy PC off the recording room easily. -Its CPU won't need to generate graphics, so I get a few CPU extra cycles for audio -My studio will be reasonably easy to move from place to place (compared to a full desktop PC with a CRT and stuff) at an affordable price. This is good because I cannot record drums at home for instance, so for this kind of thing I plan to hire a rehearsal studio. I'm still in the proccess of configuring everything, but I've already tried to export a X windows display over my net (which is 10 Mb!) and it works perfectly, I mean it's responsive enough. The laptop I'm using is a Pentium 100 MHz which you can get second hand really cheap, only fault is battery is dead (irrelevant in my application), it has a 1 Gb hard disk (enough for Linux + X windows) and a 800 x 600 TFT (the low resolution is a bugger but I hope it's just "usable"). Maybe a route to consider? Cheers, Alex >Otherwise, does anyone have any alternative suggestions about putting >together a good-as-silent machine for only a little cash?

by Mark Knecht

Hi, Does anyone happen to know of a VST that has no GUI? Or failing that, as VST that uses no fonts? (jack_fst question in sheep's clothing...) Thanks, Mark

[linux-audio-user] [ANN] Ecasound 2.3.4 released

by Kai Vehmanen

Hello everybody, it's again time for a new Ecasound release. Full details follow: --- 1. Summary of changes Serious bugs in multitrack sync code, ECI C implementation and big-endian platform support have been fixed. Support has been added for input and output of FLAC, AAC and M4A files. Improvements have been made to both FreeBSD and Mac OS X support. Many minor improvements to ECI implementations and user documentation. --- 2. What is Ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release * FLAC support added. The 'flac' tools is used for both encoding and decoding. * AAC/M4A/MP4 support added. The 'faad' and 'faac' tools are used for encoding and decoding. * Improved support for both FreeBSD and Mac OS X. Ecasound should now compile out-of-the-box on recent releases of these systems. * A critical bug was fixed in multitrack-offset calculation code. This bug was triggered by ALSA devices that limit playback period count to two (for example rme9652 and cs4281). * Minor fixes to both mp3 and ogg input support. * Many improvements to the C ECI implementation: Bug which caused losses of sync between clients and the engine was fixed. Float return values are now returned with higher precision. These improvements affect all ECI implementations that are based on libecasoundc (Perl, Python, PHP interfaces). Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes None. --- 5. Contributors Patches - Accepted code, documentation and build system changes Jesse Chappell (5) -- Bugfix to sync-loss problem in C ECI impl, improvements to libsndfile support and other bugfixes. Sean Bolton (1) -- MacOS X compability patch Adam Linson (1) -- ecasound-iam(1) update Kai Vehmanen () -- various Bug Hunting - Reports that led to bugfixes (items closed) Eric Dantan Rzewnicki (2) -- bugs in FLAC support, manpage errors Jesse Chappell (1) -- Bugs in C ECI impl. Winkler Paul (1) -- error in engine state after 'run' Feature suggestions - Ideas that led to new features (items) Didier Bellamy -- AAC input/output support --- 6. Links and files Web sites: http://www.eca.cx http://www.eca.cx/ecasound Source packages: http://ecasound.seul.org/download http://ecasound.seul.org/download/ecasound-2.3.4.tar.gz md5sum: 4d8e319b6c231acfe4884cc24114cace Distributions with maintained Ecasound support: See http://www.wakkanet.fi/~kaiv/ecasound/download.html -- http://www.eca.cx Audio software for Linux!

Re: [linux-audio-user] hdsp multiface MIDI wont work

by thewade

> Use \"modprobe snd-seq-midi\" hdsploader hdspmixer sudo modprobe snd-seq-midi aconnect -li client 0: \'System\' [type=kernel] 0 \'Timer \' 1 \'Announce \' I try this and it runs without complaint, but still no show in aconnect or pd. Any other ideas? Thanks for the help! Also, why is my AMD Opteron 64 3400+ linux laptop slower than my AMD Athlon 2600+ WinXP desktop? Both have 1Gb of ram. My laptop kernel is 2.6.9-rc3-mm3-VP-T3 and the audio latency on my laptop is much lower then the desktop, but PD patches run faster on the desktop then on the laptop.... Is there a way to trace where processor time is going? I have non-preempt tracing turned off because Ingo told me that it can create badness with the 64 bit processors. Lastly, I have an audio CD out that I made primarily with Csound. http://www.aproximation.com/ It will be for sale at www.cdbaby.com shortly, and available for download from itunes (pay) and aproximation.org(free) as well. Thanks! -thewade

[linux-audio-user] nothing works? jack/creox/jack-rack problems?

by andrej hocevar

Hello, recently I've been experimenting with different software simulating guitar effects; some were working (poorly), others didn't. There are at least three that I'd like to try and are included with Debian: creox, ecamegapedal and jack-rack. I've got them all installed but nothing works! My guitar is plugged in and I can hear it through the speakers, however none of the above software changes anything. I'm running kernel version 2.4.26 with the lowlatency patch and alsa (snd-cmipci). If I run (as root) "jackstart -R -d alsa", I get loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead At least it starts, which it refused to do before I applied the patch to the kernel. Besides, jack-rack starts as well, indicating that jackd is running. But then, nothing happens! Does anyone have any suggestions? Thanks, andrej -- echo ${girl_name} > /etc/dumpdates http://sonet.homelinux.net
