Re: [linux-audio-user] Is there a shortcut to merely test a midi device?

by Lee Dunbar

Hydrogen does not see it. Let me at this time reiterate a prior request I made: a simple bruteforce test is desired. I've already tried soo many different 'normal' configurations (GUI version of aconnect, connect the midi device to a sequencer that is launched, got nothing, tried Timidity, Muse, Rosegarden - they do not see the device, nor do I know hos to tell my midi device to be channel 1 or channel 7, etc) remember my 'too many variables' statement? I really want the simplest and most fool proof setup one can possibly attempt. Hence I asked about catting a string into a midi device - something as brute force as that, talking straight into the /dev/midi device..... -- Matthew 28:19,20 --- Benjamin Flaming <lau(a)solobanjo.com> wrote: On Thursday 06 May 2004 10:09 am, Lee Dunbar wrote: > [snip: how to test a MIDI keyboard] Another idea would be to use Hydrogen for testing. Start the program, and choose "Preferences..." from the File menu. Switch to the "Midi System" tab, and select the input which you think represents your keyboard. Click Ok, and watch the "Midi in" light. If it blinks when you press keys, you know that communication is okay. |) |)enji _____________________________________________________________ Are you a Techie? Get Your Free Tech Email Address Now!

[linux-audio-user] [ANN] AlsaModularSynth 1.8.1

by Matthias Nagorni

Hello, a new version of AlsaModularSynth is available from Sourceforge. Note: Remember to download the latest version of the LADSPA plugins by Fons Adriaensen: http://users.skynet.be/solaris/linuxaudio Otherwise the latest instrument patches just won't work ! News: - Added hplp_instrument.ams which demonstrates the new highpass filter by Fons Adriaensen. Due to the HPLP combination, the presets of this patch are quite close to some of the famous "Switched-On Bach" sounds by W. Carlos. - Added sinfonia.mid for your own experiments with hplp_instrument.ams - Fixed bug in LADSPA module where uninitialized output control ports have caused segfaults. - Several small corrections in demo patches. For more news check the respective section on the project page. Have fun !

[linux-audio-user] ALSA + Envy24HT = High pitched tone

by Mark Williams (MWP)

Hi all, Ive come across quite an odd problem. When playing audio via my Revo7.1 card using ALSA, i get a high pitched tone (est ~14khz) mixed with the audio im playing. The tone is constant and is not effected by the volume controls. The tone is only present while an app (for example aplay) is using the card. Some apps cause the tone to be louder thea others (but the tone is of the same constant freq). What makes the problem strange is that if i use JACK to play audio through the card, the tone isnt present at all. Has anyone else come across this problem? BTW, im using the latest kernel (2.6.5) with the ALSA drivers that came with it. Thanks, Mark.

[linux-audio-user] regarding mobos and CPUs

by Dave Phillips

Greetings: A client has asked me to get some opinions regarding AMD CPUs and recommended motherboards. He's planning to replace an SMP system that has apparently never worked quite right. He doesn't want another SMP mobo, and a friend is advising him to go with a uniprocessor system built around a recent AMD CPU. The recent JACK problem with AMD CPUs was a revelation for me: I'd never had any problems with AMD chips, but now I'm feeling reluctant to recommend them. Am I just being paranoid, or are there particular reasons to go with Intel instead of AMD ? My client is considering a P4 instead of the AMD, hence this infoquest... Also, what's a recommended motherboard ? Are there any mobos that should definitely be avoided ? TIA for any help you guys can proffer, it's much appreciated. Best regards, dp

Pd has this functionality with the [keys] object. But there is also the stand alone vkeybd. I think a number of soft synths come with vkeybd, most notably (IMO) ZynAddSubFX. m. _________________________________________________ Scanned on 06 May 2004 21:38:33 Scanning by http://erado.com

[linux-audio-user] should esd be running?

by Rick B

Hi all, I've been playing the new game ut2004 on my Fedora ccrma box. This game uses OpenAL for 3d sound which uses ALSA to route the audio through my on-board Nforce2 sound module. It sounds very good, however sometimes (not everytime) when I stop the game and check "ps aux" I notice esd is running and I know it usually doesn't run so it must be starting for the game. Should this be running at all since I'm using ALSA and OpenAL? If not, should I just remove it? I'm not really clear about what function esd actually serves. TIA Rick B

[linux-audio-user] wav editor that does not require alsa

by Mikhail Ramendik

Hello, I would like to do some simple WAV editing. Actually, minimum pre-mastering of an audio CD: normalizing, cutting out pieces, dividing into tracks, altering volume in some places. My problem is, at this point alsa drivers are not working for me. And in itself this is not a problem. The audio source is not the sound card, so I don't do realtime audio capture. And as I only want simple editing, I don't care about playback latency. Which WAV editor should I use? I'd like it to be able to work with OSS (perhaps via jack-oss?). Yours, Mikhail Ramendik

The problem was simply and quickly solved, and I'm perhaps off-base accusing JACK but that's where the problem came from. Maybe it was a bad make ? Anyway, if it's the opinion of the LAD developers that AMD is OK then that's what I need to know. As I stated, I've had only that one difficulty with AMD and Linux audio software, so I think I'm just being paranoid. Best, dp

[linux-audio-user] The Linux FreeVSTi Compatibility List

by Christian Frisson

Hi all, Initially posting on Tim Orford's Linux VST Compatibility Page, my quest has been to test all Win-only FreeVSTi's featured on the K-v-R database under Linux thanks to some of Kjetil Matheussen's apps and to report the way they work in my language, to speed up things a bit! I've posted the list on the K-v-R forum: http://www.kvr-vst.com/forum/viewtopic.php?t=42640 Because that's where i've found most of the plugins: http://www.kvr-vst.com/get.php Alternatively, until the nodes change while I update my bookmarks, you can browse all links to devs there: http://theremin.free.fr/hunchback/index.php?nodes=|0|461|897|1098|1103|/ Let me quote one of the first answers to the thread: "The stuck notes in some SE VSTi are most likely due to CK's Unison modules that are a little twitchy." Have your copy saved on a text file, so that you can emulate a database search. Ex: getting all interesting working plugins among all plugins stored on a text file named "VSTi": cat VSTi | grep ': W!' NB: Do you want to practise your french? http://fr.audiofanzine.com/apprendre/mailing_forums/index,idtopic,60705.html Cheers, Mr°Freeze
