Dell 1394 4 pin connector

by Kim Cascone

I have a Dell Studio 1537 which has a 4 pin 1394 connector I checked to see if my Ubuntu 10.10 upgrade would allow my Presonus Firebox to work which it allegedly does: http://www.ffado.org/?q=node/33 but my system didn't recognize my Firebox after plugging it into my Dell using a 4-pin to 6-pin cable so of course I'm wondering if I need to buy an ExpressCard Firewire adapter and if that would work does anyone have any suggestions or experience with this before I trot off to Fry's in search of said adpater?

flac2ogg in python - the right way = cross platform

by Atte André Jensen

Hi I'm doing some conversion from flac to ogg in python and I wrap sox for the actual conversion. I'm happy with it myself (I only run linux), but the script has the potential for reaching non-linux users. It seems there's no build-in (as in batteries included) way of converting from flac to ogg in python across platforms. Is this the sad truth? If so, what could be done to make the script work on the other platforms? -- Atte http://atte.dk http://modlys.dk

Hydrogen questions

by Brent Busby

My old MPC2000 (non-XL) is starting to act oddly, and it has got me thinking about whether I should even continue depending on the Akai hardware, which generates rock solid sequencer time, but is eventually going to be unmaintainable, and leave me with a lot of sequences and sample libraries in various odd proprietary formats. So while I'm working on getting my MPC working again, I'm also checking into the possibility of replacing its usefulness with a mixture of Hydrogen, Jack, Linuxsampler, and Ardour. There are a few questions though: 1) This is probably pretty basic, but...can you send each drum/instrument in a Hydrogen kit out a different physical audio output in Jack? My whole setup is very much based on physical hardware -- a real mixer board, real rack effects, etc. I haven't heard a Ladspa plugin yet that offered EQ that really satisfied me much, and I'm used to being able to do EQ on my mixer from the 10 outputs of my MPC, individually, per track, and also using rack effects from the effects loops and a real hardware patchbay. I could keep doing that if I can send individual Hydrogen tracks out to audio outputs on my RME Multiface. I could also add more outputs as needed. It'd be ideal if you could just route individual tracks to hardware outputs via Jack. 2) Hydrogen seems a lot like the Roland TR-series drum machines, based on putting notes on "ticks" on a grid. I didn't see much mention of free-form human feel drumming though. Is there a way to just not quantize at all, and realize at least a standard 96 ticks per quarter note type of resolution (or more)? 3) Also, all the discussion of entering rhythms in the documentation seemed to involve using the QWERTY keyboard, which obviously isn't going to be velocity-sensitive. Is there a way to have an outboard synthesizer keyboard (or even better, my Simmons drumset with Roland PM16 pad-to-midi) play or sequence Hydrogen patterns via midi, with full velocity sensitivity? QWERTY keyboard is an awful way to have to sequence. 4) If these are things that are beyond Hydrogen's abilities, would I be better off trying to go through Muse or Rosegarden to achieve these things? Or maybe just stick with hardware samplers for now? I'm mostly attracted to the idea of doing sampling and sequencing on FOSS software rather than on hardware samplers because the saved data doesn't have orphanhood in its future that way. Any ideas on how best to go about making Linux audio software replace an Akai MPC? -- + Brent A.

Re: [LAU] Dell 1394 4 pin connector

by Roy Vegard Ovesen

For the juju stack you'll want to grep for 'firewire'. You also need to make sure that your user has permissions to the device file. While the old stack used /dev/raw1394, the new one uses /dev/fw0, fw1, etc. Make a udev rule to allow your user, or preferably a group that you are a member of, access to /dev/fw*. -- Roy Vegard On 30 Dec 2010 03:33, "Harry Van Haaren" <harryhaaren(a)gmail.com> wrote:

HDSP mixer doesnt open. openSuse 11.3

by Yosef Werner

Hi everyone, recently updated my Suse to 11.3 everything seems working but the hdsp matrix mixer doesn't open, thus I don't get sound via the rme 9652. The hdsp config opens and the card is recognised by system. Could this be due to a problem in alsa-tools-gui 10.0.23 (in 11.2 I used alsa-tools-gui 10.0.21) My system core2duo e4500 intel MB 6giga ram rme hdsp 9652 opensuse 11.3 Appreciate your help Yosef

New music with new toys

by Julien Claassen

Hello everyone! I got myself a new piano for christmas, so I had to test it and there was just a tune, absolutely perfect for it. The Maerzlied (march song), which I had on my mind, well since March. :-0 http://juliencoder.de/nama/maerzlied.ogg Or the other one: http://juliencoder.de/nama/maerzlied.mp3 Or go and have a look at the website: http://juliencoder.de/nama/music.html The song is a mixture of 70s easy listening, entertainment music and funk. The main instrument use was the Black Grand Ambient from Sampletekk and a lot of other samples. First time I tyried the Philharmonia violin from linuxsampler.org as well. and my good, old trusty Clav has its appearance. I must say, the Clav can really be an absolutely, hellishly, cool bastard, if it wants to. :-) I tried to make it sound like 70s, so the softly filter cymbal, the slightly strange sounding Eqing on the piano are results, I had to work for, no accidents. :-) Just in case you've been wonderng. :-) Enjoy1 Feedback as ever... Welcome and appreciated. :-) Kindly yours Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de
