[linux-audio-user] midisport2x2 [WAS m-audio / midiman / oxygen8 USB MIDI?]

by derek holzer

OK, I am holding off on installing the Oxygen8 because of this weird firmware issue, but now have gotten a bit further with a MidiSport 2x2, but not there yet. On Gentoo, I emerged the following packages: fxload hotplug ezusb2131 usbmidi When I plug in the MidiSport, I get the following in /var/log/messages: Mar 22 16:05:17 umatic1 usb.c: USB disconnect on device 00:1d.0-1 address 18 Mar 22 16:05:19 umatic1 hub.c: new USB device 00:1d.0-1, assigned address 19 Mar 22 16:05:19 umatic1 usb.c: USB device 19 (vend/prod 0x763/0x1001) is not claimed by any active driver. Mar 22 16:05:19 umatic1 /etc/hotplug/usb/ezusbmidi: missing /usr/share/usb/ezusbmidi/ezusbmidi2x2.ihx for 763/1001/1 ?? So I downloaded the firmwarehotplug sources from http://sourceforge.net/project/showfiles.php?group_id=17679 and copied firmwarehotplug-0.1/ezusb/midi/original/ezusbmidi2x2.ihx to /usr/share/usb/ezusbmidi/ and now I only get: Mar 22 16:10:33 umatic1 hub.c: new USB device 00:1d.0-1, assigned address 24 Mar 22 16:10:33 umatic1 usb.c: USB device 24 (vend/prod 0x763/0x1001) is not claimed by any active driver. lsmod reports: root 16:11:00> lsmod Module Size Used by Not tainted snd-hdsp 41292 0 snd-hwdep 5472 0 [snd-hdsp] usb-midi 18588 0 (unused) snd-intel8x0 20388 0 snd-ac97-codec 49388 0 [snd-intel8x0] snd-mpu401-uart 4304 0 [snd-intel8x0] ohci1394 27272 0 (unused) ieee1394 52292 0 [ohci1394] snd-rawmidi 15552 0 (autoclean) [snd-hdsp snd-mpu401-uart] snd-seq-device 4452 0 (autoclean) [snd-rawmidi] snd-pcm 69088 0 (autoclean) [snd-hdsp snd-intel8x0] snd-page-alloc 7380 0 (autoclean) [snd-hdsp snd-intel8x0 snd-pcm] snd-timer 17380 0 (autoclean) [snd-pcm] snd 37252 0 (autoclean) [snd-hdsp snd-hwdep snd-intel8x0 snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device snd-pcm snd-timer] soundcore 4548 4 (autoclean) [usb-midi snd] What to do next?

[linux-audio-user] Re: hard disk sampler

by Juhana Sadeharju

>From: "Hawkeye Parker" <hawkeye.parker(a)autodesk.com> > >essentially, what i'm looking for is some way to reproduce the ~nature~ >of Sonic Foundry's Acid for Windows. i don't really *want* Acid, or even Does the suggested Specimen + Seq24 work that way? I have used Rosegarden with loop samples. Problems: audio clips are skipped and played at wrong speed, could not set tempo properly for some reason, there are silences between consequtive clips. I have also hard time to make anything usable with the loops. I'm really beginner in arranging. It took me quite a while to notice that the loops I have can be grouped to groups of slightly different lengths. Further, a group can have 0.5, 1 and 1.5 length loops. Different groups could indicate the loops of different groups simply cannot be used in the same arrangement without tempo change. Try the samples yourself: www.mountedbythegods.com ftp.funet.fi/pub/culture/music/western/Yello/ (for tar.bz2 file) The samples are provided by Boris Blank of Yello. If you're curious: very recently two interviews of BB appeared at Native Instruments and Emagic websites. I wish we would have software similar to Logic. BB provides Absynth2 sounds at NI site, but they are usable and available only for Absynth2 users. >any suggestions? Next I will check Ardour. I'm compiling a list of software which comes with source code. Below I have appended some picks. I too have used Csound for arranging (at 1997). I wrote C code such as track(16); push(); bskip(6*8); for(i = 0; i < 10; i++) { apps(16,0.8); } pop(); and that was made to Csound sco file like this i16 17.527846 3.316531 0.800000 i16 20.436936 3.316531 0.800000 i16 23.346026 3.316531 0.800000 i16 26.255116 3.316531 0.800000 i16 29.164207 3.316531 0.800000 i16 32.073298 3.316531 0.800000 i16 34.982390 3.316531 0.800000 i16 37.891482 3.316531 0.800000 i16 40.800574 3.316531 0.800000 i16 43.709666 3.316531 0.800000 and Csound orc file looks like this (close enough) instr 16 asig1 soundin "oneshot3.wav" outs p4 * asig1,p5 * asig1 endin If all those new audio software still fails to compile or have major problems, I have to return to the above simple approach. Instead of Csound I could use software similar to rawseq or ss.

[linux-audio-user] S/PDIF over CAT5

by Steve Harris

You can get passive converters: http://www.svideo.com/500020.html so it can't be that complicated, and its cheaper than going to AES/EBU and running that. This only requires two conductors from the CAT5 cable, so you could even run it along with 100baseT ethernet, but that might be naughty :) - Steve

by Marco Scoffier

Hello, Flux factory in Queens, NY is hosting an installfest which will have a focus on getting artists up and running with audio software on linux. If anyone one on the list wants to come and help out you will be more than welcome. There is much interest in Ardour and in Pd. Also, if anyone has a cool demo, we have a projector and a PA for discussing some of the possibilities of Free Software audio, and I would be more than happy to share the stage with someone. Of course if you need help getting something installed, then come on down. -- Marco ---------- Here is the announcement flux sent out last week: The Technology Initiative @ fluxfactory.org http://www.fluxfactory.org/work.htm Sunday, March 28th 2-6pm - Install Fest & Linux Audio For those who've always wanted linux running on their computers, but never dared to install it alone. This is a great opportunity to learn the basics and get started on how to improve your life with free software! Marco Scoffier will also demonstrate using audio in a linux based environment, covering certain programs. Bring your laptops, even desktops (backup your files first!). Flux Factory is in Queens NY.

[linux-audio-user] Major problem with RME HDSP/Multiface and a 64-bit AMD laptop

by Ivica Ico Bukvic

First off I would like to extend my sincere apologies for my atrocious cross-posting. I am currently in a rather desperate situation and would highly appreciate any help I can get in this matter. <Begin long blurb> I recently got my hands on the eMachines M6807 64-bit Athlon 3000+ and I must say that the notebook is very nice. The gripes I do have about it are mostly of cosmetic nature. The performance is in many ways unmatched. After owning the notebook for just about a month I finally found some free time to install the Multiface/HDSP on it. I was immediately very unpleasantly surprised by the fact that the sound output using the ASIO drivers (and Linux ALSA drivers) yielded similar results -- distorted audio. Now here's the catch. When I use the soundcard in mme, DirectX, or any other driver form, the soundcard works perfectly (albeit no multichannel capability). But when I use ALSA in Linux or ASIO in Windoze (XP Home version), the sound plays as if it's interpreted slower than it should be (2 whole steps, or 4 semitones lower and comparably slower) with a bad distortion, as if one is using a very lousy vocoder. There are no drop-outs or choppiness (I did not try JACK, though, so I don't know about the explicit xruns) which leads me to believe that the throughput is not the culprit, but the output simply is useless. Here's some additional info/problems I am aware of: 1) The manufacturer of the notebook is Arima (company that supplies many other companies with the same chipset/chasis) has shipped this notebook with a crappy BIOS (Linux at boot time complains about DSDT being all fubared and fails to properly allocate IRQ's with the acpi turned on; also apic seems to be fubared as well). Some of these issues have been addressed in the 2.6.2 kernels via several patches with a spotty success and currently I need to boot with no acpi or apic to get everything working properly (otherwise almost no peripheral works properly). So, I know for a fact that BIOS is sucking rather bad... Contacting support so far has only suggested that there should be some bios updates coming up soon, but I'll believe it when I see it (OTOH this model is supposedly selling rather well as it has been apparently licensed by at least 6 different companies across the world including the voodoopc, so I guess that should provide some leverage). 2) I am using Mdk 10.0 Community release. No problems there that I can notice. Installed the hdsp utils and everything worked like a charm, except of course for the sound output. 3) The pcmcia card in XP is detected as the generic pcmcia and is using default XP drivers without any conflicts and/or apparent problems. 4) The pcmcia card (at least in Windows) is sharing its IRQ only with the HDSP when plugged in (IRQ 17 -- there are total of 24 due to APIC being enabled in XP), but I don't think that should be considered a conflict (please correct me if I am wrong). 5) In Linux due to fact that the computer boots without APCI and APIC enabled, my guess is that it is using only first 15 IRQ's (like the old APM-based PC), although I need to further investigate this. To the best of my knowledge no IRQ conflicts have been reported by the syslog when using this setup. 6) The pcmcia cardbus is using the yenta_socket driver in Linux, but curiously cannot be used with the APCI (most likely due to fubared BIOS), as that immediately freezes the system. 7) In Windows, I tried 2.53 and 2.62 drivers, with the latest firmware (11). Using different drivers made no difference. I tried several ASIO-capable applications in order to make sure this was the case. 8) No errors during use of Multiface are reported in either Linux nor Windows. Finally, having used Multiface on Inspiron laptops, I am quite familiar with the sound that is being generated by the lousy throughput (crackly stuff) and I must say that while this sounds very similar, there are couple of things that make this sound different: 1) No matter which latency I select in hdsp configuration tool, the sound remains the same. 2) When overclocking the laptop (this beast that runs at 1.8GHz oc's via software without a hitch to 2GHz with no overheating and no instability whatsoever), the pitch and the speed of the output rises (wtf?). At 2GHz it's about 2 semitones higher (and comparably faster). I am having a feeling that if I could oc it for another 200MHz, I would have the right playback speed :-). OTOH, when the laptop downclocks to preserve battery (800MHz) the sound playback remains at approx. the same speed but with a timbrally somewhat different artifacts like the one at 1800MHz. 3) When using mme, or DirectX or any other non-ASIO playback format in Windows, no matter what the latency in the hdsp config tool, the sound output is flawless. 4) I also read that some of the 2.6.2 Linux kernel patches were incorporated to fix the fact that Bios represents the CPU speed (via ACPI?) as 1600MHz which is apparent in the Windows if one right-clicks on the My Computer icon and clicks on Properties. However, programs like CpuID read the frequency properly as 1800MHz. 5) FSB on this beast to the best of my knowledge should be plenty fast (200MHz x ? -- I heard it's like 1600MHz (8x), but I find that hard to believe). Hence, I would be seriously surprised that it is a case of a lousy cardbus implementation... Although, I guess everything is possible... <end long blurb> Whew! That should be about it. If you need any syslogs or any other info, please contact me and I will gladly provide them. I would simply appreciate any insight at this point as I have purchased this laptop primarily for the music-making purposes and not being able to use it with the expensive Multiface makes either this laptop or the Multiface an expensive brick (I say this as I did hear that M-Audio Firewire 410 runs just fine in combination with this notebook). Cc: RME support US/international LAD/LAU Alsa-dev/user I would also appreciate any help from the RME tech department as this may potentially stem from the fact that the system is 64-bit (although I am NOT running 64-bit versions of either Windows or Linux) and that the drivers are somehow not taking that into account. Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

[linux-audio-user] MicroKorg -> MIDI -> Linux

by daniel.vincent＠blueyonder.co.uk

Firstly, thanks to everyone who gave responses to my query regarding triggering samples. I'm looking into a number of the different options, and I think it's about time I worked out how to use pd! I have a new challenge/question :-) My latest purchase, a MicroKorg synthesiser, has MIDI connectors which I have hooked up to my soundcard's game port. I've set the required settings on the Korg, WTF do I do now? :-)))) I've had a quick Google around at documentation, but if anyone could recommend a good tutorial/book/site for setting this kind of thing up then I'd be much obliged! I downloaded the new version of Dynebolic the other day. Another fine release, something that I'm regularly recommending to friends and fellow home recording geeks. cheers daniel www.soundclick.com/theparallelrise www.soundclick.com/onionjack www.southlondonlive.org
