Thanks, Steve. I feel clear on this now -- and have ordered my Delta 66!

[linux-audio-user] A Newbie's New System?

by Scott Downie

After 17 years of making music on Apple-brand computers, I'm finally fed up with the state of affairs in the Mac and Windows worlds and want to migrate to Linux. Unless there is some major issue with it, I think I'd like to use the Debian distribution, particularly since the DeMuDi developments are on the horizon. Even though I've got a number of old computers taking up space, I figure I might as well start with a clean slate. So I'm asking what kind of hardware would be best for a respectable Linux music setup? Is the Hammermill audio card the best option? Do I need a separate MIDI card or can I run everything through some USB interface(s)? From the limited amount I've read, it seems as if the motherboard should be Intel-based, rather than AMD. I don't care about video. I'm only concerned with maximizing audio processing power. I'd like to piece together a system (not including monitor) for less than $1000 (USD). I can get and assemble any set of pieces, no problem. I just want to get pieces that can work together harmoniously. This will be a dedicated Linux machine--no more dual-boot crap for me! Any and all suggestions are welcome. Thanks! Scott

[linux-audio-user] programm for tuning

by kern＠kontaktkode.ch

Hi folks Is there already an application that makes piano tuning easier? That would be done by: -analysing the waveform coming in through the mic -comparing with an ideal one (ideally depending on choosen temperature - that's why a laptop (besides the cost) would be optimal for this task) -giving a gui-sign to adjust to this (as the LEDs of an analog tuner). Are there other problems to encounter I forgot now? Thank you for your suggestions. David

[linux-audio-user] multiple unsynced cards

by Patrick Shirkey

I just managed to get the code from Jeorn working on my crappy cards here. (it also allows me to use a crappy card and my quattro together or I guess even all three for eight channels i/o ;) So that makes at least two people who have done this.

[linux-audio-user] getting started with MIDI

by Christian Schoenebeck

Hi everybody! Can somebody help me with my MIDI setup? I fiddled a little bit with it but couldn't get it work. I'm using a Terratec EWS64 XL, I've installed it's driver (sam9407), so the audio section works. But what do I have to do for being able to use it's MIDI ports? At the moment I'm using KDE 2.2 and maybe want to use Muse or something like that, because it's very similar to Cubase. Do I have to add a raw device to artsd or directly to Muse? Sorry for this stupid question, but I haven't found a HOWTO about that and I already tried something with Muse but it terminated after the first MIDI Event occured. Thanks for any help! Christian Schoenebeck P.S. these are my available sequencer devices: crw-rw---- 1 root audio 14, 1 15. Apr 2001 /dev/oss_sequencer crw-rw---- 1 root audio 145, 1 6.

[linux-audio-user] JACK support for maudio quattro.

I have just been able to get crystal clear sound through this card using the latest patch to the usb-audio driver in ALSA cvs and jack. ooooooh yeaaaah! -- Patrick Shirkey - Boost Hardware Ltd.

[linux-audio-user] Jazz++ on RedHat 7.2 anyone ?

by Stephen Burgess

Hi all, I am desperately trying to get the Jazz++ sequencer to run on Linux 7.2 with a softsynth and ALSA 0.9.0. I manage to use iiwusynth with pmidi or vkey in the following way : $ iiwusynth -m alsa_seq sf/sYnerGi-8Mb.sf2 $ vkeybd --addr 128:0 But when I launch jazz, I get the following error messages : ioctl: Inappropriate ioctl for device ioctl: Inappropriate ioctl for device subscribe: Inappropriate ioctl for device ioctl: Inappropriate ioctl for device unsubscribe: Inappropriate ioctl for device I never got any sound out of the pianoroll, I never got any sound when loading a midi file and pressing play. I checked how the interface works by downloading the win32 version. I tried both the rpm and the binary versions (ver 4.1.3) as I couldn't manage to compile version 4.1.8. I am using the default jazz.cfg file which is set for ALSA. What am I doing wrong ? Is Jazz++ not meant to use alsa_sequencer ? -- Operant conditionning : A process in which responses are learned on the basis of their rewarding or punishing consequences.

[linux-audio-user] monophonic audio -> MIDI

by Will Benton

Hey all, Does anyone know of a good program that converts monophonic audio to MIDI data? (If such a program exists for ALSA, so much the better!) thanks, wb -- Will Benton | "Die richtige Methode der Philosophie wäre eigentlich willb(a)acm.org | die: Nichts zu sagen, als was sich sagen läßt...."

[linux-audio-user] vxpocket + linux - custers last stand

by matthew yee-king

Hello/ Bonjour I am a VXpocket2 owner. I use a powerbook g4. I have now completely transferred to a GNU/ Linux OS. This means the card is now useless. I am writing to find out if you have any new plans to support GNU/Linux? I notice that you have a macosx driver now - maybe this *nix experience could be transferred in some way to the development of a GNU/ Linux driver? Do you find it sad to be one of the few red marks on this page? http://www.alsa-project.org/alsa-doc/ If there is no linux driver, i hope the second hand price of your cards is as high as the new price.... best matthew yee-king (a disheartened customer)

[linux-audio-user] alambik

by Mark Constable

This may be of interest. They have commercial M$ packages to sell but the viewers seems to be free and they claim something about their system is "open source", which I presume is the scripting language... I've yet to locate any SDK or API info. http://light.alambik.com/ It MIGHT be a more open flash-like option. Maybe. This is the response I got when I asked if linux is supported. --------------------------------------------------------- The linux version of our viewer is under development. Stay tuned ! We hope to release it before end of the year 2002. The MacOs version will be released later. --markc
