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

by Lee Dunbar

Uhhhh..... My BIOS is an issue? You lost me, Ben. My motherboard manual *tells me* to set the BIOS to game if I want to use a joystick on the port, or set the BIOS to *midi* if I want to attach midi devices to it... Same situation for both the Athlon/Linux box (using AMI BIOS) and the Celeron/WinME box (using an award BIOS). The motherboard owners manuals for 2 different systems are not to be believed? I think these boxes are fairly representative of common PCs. Also, nothing anywhere (in all the manuals) has ever mentioned needing any adapters, can you post manufacturer names and part numbers for what you are referring to? And the computers I've mentioned are PC, I know that older Macintoshes (68k era stuff) needed adapters, is that what you are thinking? Finally, the cable that came with the keyboard has a din on one end (this end plugs into the keyboard), and the other end of the cable splits into two; the 2 ends are male and female, and the keyboard documents say that one connection is for the PC connection, the other is for a joystick. Both of these connections are D-SUB designs, of the proper type to mate with the midi connector on the 2 systems. I believe this is the cable to which you have referred as 'midi to gameport cable'. Does this cable replace the adapter that you mentioned? -- Matthew 28:19,20 --- Benjamin Flaming <lau(a)solobanjo.com> wrote: On Thursday 06 May 2004 10:09 am, Lee Dunbar wrote: > [snip: trying to connect an old MIDI keyboard from windows 3.x era] Just for the record, I also have such a keyboard, and it still works just fine.

This *may* be wrong, and *might possibly* be the source of your trouble. Is the port actually a MIDI port? If it isn't, you might be confusing things by telling the BIOS that it is. I'm not sure how that particular BIOS setting would affect port communication, but it is common to use a standard gameport for MIDI, via an adapter. You shouldn't have to change your BIOS settings. You could probably do a bit of testing under Windows by installing the gameport MIDI driver. I don't remember what the driver is called, but look for something with MPU401 in the name. It may be installed already. I'm not advocating that you move away from Linux, of course, but this could give you another temporary testing platform by which to establish whether or not your keyboard and cabling is okay. Good luck, |) |)enji _____________________________________________________________ Are you a Techie? Get Your Free Tech Email Address Now! Visit http://www.TechEmail.com

[linux-audio-user] Santa Cruz Turtle beach soundcard and multi outs...

by Russell Hanaghan

After digging around I got this card using the cs46xx alsa driver to show 2 ins and 6 outs running jack. I am yet to test sound thru them but will shortly. I figured I'd need to set up a specific .asoundrc file for this but turns out if you try the "default" setting in qjackctl you can set up jack for 2, 4 or 6 outs on a surround type card. At least with this one anyway. see the alsa.conf group of scripts. There are several of which all appear to have layout for the various surround (4.0, 4.1, 5.0, 5.1, etc) configurations. I figure this might work with SBLive 5.1 too? Most prolly know this but for those noobs like my self... R~

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

by Lee Dunbar

Thanks for the heads up on amidi - can't wait to get the time on the SuSe box so I can try it. FWIW, what is PD? I've searched sourceforge for the string 'midi', nothing stood out (my newbieness thinks that means 'Public Domain').

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
