Hi Eduardo, It's on the page actually ;) urpmi.addmedia thacs.rpms http://rpm.nyvalls.se/9.1/RPMS with hdlist.cz for 9.1. if you like to try the absolutely newest you should use the repository for 9.2. (many of the apps work with 9.1 as is, though not all) (rpm.nyvalls.se/sounds9.2.html) As for MusE I think we will release an even newer version in a week or so, 0.6.3, maintenance release while waiting for 0.7.0 :). /Robert

Re: [linux-audio-user] Recommendatio wanted

Joerg wrote: "... it does not occur as rarely as you might think." This was a comparison, not an absolute measurement. The comparison results suggest (not prove) that it's something else, not the driver. If it's the driver, then why is there a measurable difference between two sf2 files playing the same MIDI file with the same patch number and same channels? It could be, but I see no proof. "It is practiaclly impossible to play these examples without dropping notes. Especially if the drum or percussion fails this is very angry." Compared to the dropping of notes by Rosegarden (older version) and Muse for other reasons, this wavetable synthesis problem is a minor annoyance. The timing for both of these sequencers is noticeably off, and the older version of Rosegarden gets certain MIDI files completely wrong with stuck notes, etc. on my system. A good test example is bohemian.mid in Nathan Laredo's playmidi. "It happens also if I use the FluidR3 font. And - to make this clear - independend of whether I play with NoteEdit or the exported MIDI files with any arbitary MIDI player and/or sequencer or whatever you have in mind, as long as these MIDI player/sequencer uses the hardware wavetable synthesis." "And more important: It never occurs with AWE64 independend of the soundfond and/or the MIDI player and/or sequencer." This is to be expected for both a driver problem and a loading problem or timing problem. It could also be some sort of firmware problem, a circuit design problem, logic problem in the chips on the soundcard, etc. It still seems premature to conclude that this cannot be anything else other than a driver problem. Maybe it is, maybe not.

[linux-audio-user] Analyzing ogg files

by Mark Knecht

Hi, How can I get info from an ogg file that tells me things like sample rate, bit-depth and other information? sndfile-info doesn't seem to know about ogg files. (A surprise to me...) Thanks in advance, Mark

Joerg wrote: "Known bugs: - MIDI on SB live drive not working properly. - wavetable drops notes sometimes. (a good test example wanted.)" Exactly. No information on the cause, nor whether it is driver or not. It is simply noted that notes are sometimes dropped with wavetable sythesis. No definite conclusion can be drawn from this "bug report.". "http://rnvs.informatik.tu-chemnitz.de/DROP/gap.html" This file caused NO problems for emu10k1 and pmidi w/EXTERNAL synth (N264). Rosegarden (older version) dropped many, many notes; Muse dropped many notes under certain types of load (switching desktop, for example), even with external synth, even with Terratech EWX 24/96 and Roland XV-3080. With wavetable synthesis, I did now finally see 2 or 3 dropped notes with pmidi. The 8mbgmsfx.sf2 soundfont supplied by Creative Labs was worse than a 4 MB Steinway piano-only soundfont file. The Steinway soundfont VERY RARELY dropped any notes. But I could make the problem much worse by adding load, just as Muse and Rosegarden do. I'm not at all convinced that this is a driver issue. Wavetable synthesis should be more difficult for the system than external midi, so timing with O/S's such as Linux and Windows could be and eventually will be affected. Anyone actually know in detail the emu10k1 driver situation? The bug report isn't really of any help to determine the cause.

[linux-audio-user] Announcing the ultra-mega-alpha release of Specimen

by Peter Bessman

Specimen is a midi controlled sampler, and it's very first public release is available from http://www.gazuga.net/specimen.tar.gz In all honesty, I advise against downloading this in it's current state unless you intend to hack on it or play with it for sheer amusement value only. There are a few TODO items that must be taken care of before this can be considered usable software (as the next release will be). The main reason for this release is because I said I was going to make a release in a couple of weeks 15 days ago. It's very nascent stuff. You have been warned. [pb]

[linux-audio-user] arecord and xrun

by Ken Dere

I am trying to record some phonograph records using arecord. I get xruns of about 0.5s or so. I have tried increasing the buffer size which worked up to a point. I have tried running as root which didn't help. Is there anything I could do short of applying the low-latency patch to get this to wok? thanks, KD

Re: [linux-audio-user] Recommendatio wanted

by davidrclark＠earthlink.net

Has anyone else seen dropping of notes with EMU10K1 ALSA drivers mentioned by Joerg during wavetable synthesis? I have seen dropping of notes with both EMU10K1 and ICE1712 EXTERNAL MPU-401, but I don't believe this is because of the drivers. Neither Muse nor Rosegarden function well on my machine, but pmidi has absolutely no problems. I have been assuming that these dropped notes are due to the larger load of GUI MIDI sequencers versus command-line sequencers, not the drivers. Rosegarden is worst, Muse next. BTW, Rosegarden is much, much worse for me than any Windows sequencers I have. I run 2.4.20 with the usual kernel patches for low-latency. Just curious about what others have seen. Thanks!

I did try to load a soundfont, but I had each track strip turned off. The button seems pushed when it's off, contrary to my belief. For the moment it's just playing what I've recorded, is there a way to play live with the soundfont sounds? Later today I will try a newer muse version, as Robert suggests. Thank you, Eduardo.

Re: [linux-audio-user] ALSA/OSS Free supported sound card with 16inputchannels

I'm talking about a fancy phone answering machine where the phone does not support modem voice commands. The application will accept an incoming phone call on one of up to 16 phones and start an application that stores the incoming voice into a WAV file. The phone will generate an analogue signal, because the D/A step accounts for an important part of the quality of the final voice, so it will have to connect to a sound cards inputs. Ideally we would use an artificial ear, but then we would not be able place it into a 19" rack because of all the background noise. >It should be relatively easy to design your own app/script which takes >the raw data and writes it to multiple files.
