[linux-audio-user] N00b'ish questions

by Andrew Lewis

Well I've got a working Linux studio setup finally. :) Rosegarden is seeming quite nice and I've made one or two half-decent noises. I have a few daft questions: 1) How does one use the DSSI sampler instrument? Couldn't figure this out. I've also installed the Chionic sampler, which I can play via my MIDI keyboard by connecting it up to it with JACK: however for some reason I'm unable to control it through Rosegarden, whereas I can control eg. amSynth without problems the same way - confusing?? 2) In your opinion: realtime music production: kief or kak? I find that even without effects, triggering eg. Hexter lots of times will cause xruns on my system (2.4GHz p4, 512MB RAM); which basically totally screws me out of ever getting a decent recording out of Rosegarden. :( Which makes me sad. :( I'm also interested in making really heavily processed music (it should sound as if the computer were violently shitting it out :D), but this is a problem for me where this can't be done realtime. :( LMMS is a suitable app to use in this respect, but is not really mature or stable enough for my liking, and the it's not nearly so nice a sequencer as Rosegarden. 3) More dumb questions here... How can I make girls like me? etc. Best Regards, Drew

This is a bit of a shot in the dark, but 2.6 has been fairly, um, "loose" shall we say?, regarding all the devices and reordering. There are some similarities between some of what you report and a problem a colleague had on a Gentoo box, with clock trouble and a few other goodies. It turned out to be a bad X driver for his (Nvidia?) card, and building the latest driver fixed some seriously unrelated things. I don't know what video driver you're using, but you might check this, as unrelated as it seems.

[linux-audio-user] [ANN] Kontroll

by Florian Schmidt

Kontroll is a small app that continously reads the mouse position on the screen and translates the x and y components into midi controller messages, which can be sent to any alsa_seq based midi app (just hook it up with your favourite patch bay). d'l and screeny here: http://tapas.affenbande.org/?page_id=42 It is inspired by the Supercollider3 MouseX and MouseY UGens. Have fun, Flo -- Palimm Palimm! http://tapas.affenbande.org

[linux-audio-user] Rain

by Folderol

Well, the title of a track actually. I think it's just about ready to go into the wild along with my other stuff. I'm still not certain about the instrumentation, so welcome comments. It is a 'pure' Linux track using Rosegarden and ZynAddSubFX. It also pushes my current system to the absolute limit :( With All windows minimised the instant I start Rosegarden, I can just about keep the CPU usage below 90% while recording it! http://www.folderol@ukfsn.org -- F

[linux-audio-user] Internet Music Business Models + Logos

by Carlo Capocasa

Hi! Thanks for the great discussions in the Marketing Free Music thread... Very enlightening! I tried to pick up all the input I could get and distil it into something useful. These ideas are a product of the discussion (the way I understood it), my imagination, and a lot of thinking. They are not tested, not finished, not the last word, just a few ideas! I should also mention by most standards I am considered anything from a little wacky to completely smack-whacking insane. Maybe you think this is a good thing. In any case :) I am coming to the conclusion that 'Free' as Richard Stallman and these folks understand it refers to the absence of outside control (as through schools, universities, corporations, asylums, governments, or prisons). Quite simple. 'Free' means: Not reporting to anyone. I have found there are three useful levels of freedom in distributing your digital art over the web, each completely free in the free speech sense, and a variety of freedoms in the monetary sense. (Of course there are any amount you can make up, these three are simply those I happened to think of). 1. The Small Business Entrepreneur You create art with whatever tools you have available and sell your content over the internet. 2. The Cyber-Street Musician You create art and distribute it free of charge, with the understanding you appreciate donations and even rely on them. 3. The Angel You create art and distribute it free of charge. You do not accept donations. Either you are very trusting your needs will be met or you have some other source of income. MARKETING TACTICS We all need marketing. In its best sense, it simply means that there are no obstacles people need to get around to get to your music. Clean up the dog poo in front of your store. Sure it's flattering to see to what lengths people will go to get your product, but maybe that length could be reduced to one: How much will they pay? 1. For the first business model I was thinking of selling music on an 'All Rights Reserved' basis, but with FULL RESALE RIGHTS. In other words, people are allowed to distribute your work for free if they want to, but there is a little incentive not to, because they can also sell it to their friends. This is very empowering to people since it encourages them to create additional sources of income for themselves except their jobs. To give you a little leverage, some exclusive content for people who buy direct (liner notes, additional artwork, exlusive bonus tracks, anything bonus really) on the site appears a good idea. 2. For the street musician the most important thing appears to be some way of reminding people to please donate if they like your music. People are happily minding their own business every day while you are counting your food coupons, even if they are in principle willing and able to donate. That's not evil, it's just human nature. Sometimes it takes a little knocking on our door to get our attention. 'Oh right, that music, yeah I've been enjoying it, I'll give him a couple bucks.' Actually, perhaps it would be a good idea to find some way of getting people to donate before they close your web site. Or, alternatively, some way of keeping them coming back (new content! new content! new content! online community! Whatever.) 3. Well not much marketing needed here I guess, unless perhaps in terms of 'number of downloads'. I guess 'Make a Nice Web Site' would be sound in any case and also here, right along with 'make downloads clearly visible'. LOGOS In order for people to know what is expected of them I have created a set of logos (SVG, http://shelljam.sourceforge.net/musicstream.svg). For a little familiarity value I created a 'free' brand (anyone can use it) called 'Musicstream'. If anyone has a better idea for the name please post; I like this because it is broad (music can be sold or given away, it is clear we are talking about music over the web but not CDs, while everyone is free to offer CDs AND musicstreams, and it has that 'new and cool' twang magazine editors who don't know what they're talking about but are hip will probably pick up on.) Lemme know what'cha think guys (and girls, and hermaphrodites, and non-sexuals)! Of course, the most important thing is... Let's all actually make some GOOD music and everything I wrote here will probably be pretty much irrelevant... or at best the Sake that goes with the Sushi. ;) Lemme know! Carlo PS: The ideas of 'Made with Free Software' and 'Geek is Cool and Sexy' have not been forgotten, but as far as I can see should be launched as seperate campaigns so non-Geeks and Propellerheads users can be part of the Phun as well!

[linux-audio-user] battery strangeness

by Atte André Jensen

Hi I have a laptop that runs debian/stable with a homemade 2.6.15.6-rt21. I use it live with csound5.Two days ago I was at a rehearsal where I forgot my power supply. Everything ran fine except 2 things: 1) I have a csound instrument that reads the interval between taps and writes a percentage of that to the delay time of a global delay (code attached). That was totally screwed up, and taps would translate to something 2-3 times faster. 2) At the end of the rehearsal the clock of my laptop was late (I think, maybe it was early) by something like 30-45 minutes. Normally the clock is just fine and I set if from rdate every hour, so It had dropped over 30 minutes while running about two hours on battery. A related issue: Today I was watching an avi-file in xine, during which the powerchord popped out. Suddenly the audio became chopped up as if the computer couldn't keep up. Putting the cable back in didn't change anything. But after loggin out/in of X (and keeping the power chord in place) everything was fine again. What on earth...???? I'm clueless. I have disabled frequency scaling in the kernel, and the system is quite sleek running openbox and a minimalistic install. Any ideas as to where I should look would be appreciated. BTW: All behaviour is reproducable. I didn't, however reproduce the clock strangeness from 2)... Here are my .config and the tapping csound macro: http://www.atte.dk/download/.config http://www.atte.dk/download/tap_tempo.macro -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] no playback with grecord

by Bernhard Kleine

hallo, i would like to listen to a .wav file which i open in grecord, but i fail. I am using gnome and alsa and have in the mixer everything enabled. But nothing can be heard from the speakers. However, when I enable a buttom in the gmixer some noise can be heard, showing that the speakers are ready. Could anybody point me to the proper enabling of playing .wav>? Thnx a lot Bernhard
