[linux-audio-user] DSP2000 C-PORT and MIDI input

by Emiliano Grilli

Hello, I have recently bought the ice1712-based DSP2000 C-PORT from Hoontech and I'm really satisfied with it. I only have a little problem: MIDI! The card has 1 MIDI in and 2 MIDI out, and the 2 outs are working fine. However, I can't get anything from MIDI in :-( Anyone has that card and can confirm this problem or I have to check my hardware? Maybe ALSA get confused? With aconnect I see 2 devices (0 and 32) both as inputs and as outputs... I've tried on the staudio.com forum and they suggest to test the card under windows, but (ehm..) I don't have it... Any suggestions? TIA -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'

[linux-audio-user] ams, jackd & X as root? on debian

by Eric Dantan Rzewnicki

hello, I have jack installed and working now. So, now I'm trying to get AlsaModularSynth compiled and running. Has anyone else accomplished this in debian stable (woody)? I installed libqt3-mt (along w/everything it depended upon), fftw-dev, fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to edit the top of make_ams to agree with the location of the qt3 libs, bin and include directories on my system as best as I could figure ... but I'm not sure I got it right: QT_LIB_DIR=/usr/lib/qt3/plugins/styles QT_BIN_DIR=/usr/share/qt/bin QT_INCLUDE_DIR=/usr/include/qt it seems to compile OK when I do: make -f make_ams though there are a lot of warnings about comparing signed to unsigned and other warnings that flew by. Are these benign? Anyway. I end up with an executable ams. When I run ./ams I get this: ./ams: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory I have that in /usr/local/lib/libjack.so.0 so creating this link appears to help: box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0 Is that the correct sollution? but, now: box1:/home/eric/audio_code/ams-1.5.5# ./ams ams: cannot connect to X server I assume this is because X is running as me (eric) and not as root. I'll try getting out of X and starting it as root as soon as I finish writing this message. But, is there a way to let root connect to the X server that's running as eric? I was sort of ok (well, not really, but I'm giving it a try) with the idea of running jackd and its clients as root ... but, running X as root, too? that makes me more nervous, somehow... maybe I shouldn't be nervous about that ... I'm not sure. anyway. i'll give it a shot with a root X session. I'm thinking that maybe I should patch and recompile the kernel and recompile jack to enable capabilities so I don't have to run as root. Do those of you running jackd as root also run your X session as root? Thanks for listening, Eric Rz. PS If all of this has been covered before and my questions are annoying you, feel free to send me to the archives. I try to follow jackit-devel, but most of it seemed to go over my head before I actually started to try it. So, re-reading the past couple months would probably do me some good now that I have the real thing in front of me. -edrz

[linux-audio-user] Trying to record audio from line in and additional questions

by Sylvain Robitaille

First the vitals: The computer system is a 400 MHz K6-2 with 512 MB memory, and a Hercules Fortissimo II (Cirrus Logic Soundfusion CS4624 processor) sound card. The OS is Linux-2.4.20 (built up from Slackware-8.0, with kernel patches and package upgrades). I have the following ALSA components installed: alsa-driver-0.9.0rc7, alsa-oss-0.9.0rc1, alsa-utils-0.9.0rc7, alsa-lib-0.9.0rc7, alsa-tools-0.9.0rc7. The kernel is mostly monolithic, with the following options (abridged to include only those I know are relevant; if folks want the complete listing, I can easily provide it): CONFIG_EXPERIMENTAL=y CONFIG_MODULES=y CONFIG_MODVERSIONS=y CONFIG_KMOD=y CONFIG_LOLAT=y CONFIG_LOLAT_SYSCTL=y CONFIG_RTC=y CONFIG_SOUND=y ALSA is the only component that I have modularized (only because I don't have the impression it can easily be just built-in, actually), and the following modules are loaded: Module Size Used by snd-mixer-oss 11120 1 (autoclean) snd-cs46xx 58096 1 (autoclean) snd-pcm 50752 0 (autoclean) [snd-cs46xx] snd-timer 9392 0 (autoclean) [snd-pcm] snd-ac97-codec 26912 0 (autoclean) [snd-cs46xx] snd-rawmidi 11808 0 (autoclean) [snd-cs46xx] snd-seq-device 3824 0 (autoclean) [snd-rawmidi] snd 27280 0 (autoclean) [snd-mixer-oss snd-cs46xx snd-pcm snd-timer snd-ac97-codec snd-rawmidi snd-seq-device] I've been using Linux with OSS and a Media-Vision Pro-Audio-Studio-16 soundcard for years, and have basically had very little trouble with that combination. Upgrading to Linux-2.4.x caused the sound output to be rather noisy, so I recently took advantage of the situation to buy a new soundcard, and upgrade to using ALSA (which I've been wanting to do so I can investigate certain rather exciting applications such as Ardour and the new Rosegarden). The applications I've been using for years with OSS, (notably Dap, Mixviews, Aumix, and a few others) all appear to mostly be working fine, presumably through the ALSA OSS emulation. Aumixer now shows some lables (PhoneIn and Video) which don't correspond to any inputs I have on my soundcard, while some others (IGain and Line1) don't appear to have any use, given the way I'm currently using the card (signal from a hardware mixer going to the Line input, and signal from the main, front line output going back to the mixer). I can play back sound files without any problem. In fact I've also tried a few new (to me) applications, such as Audacity, ProTux, and (though I'm having problems with it I won't cover here) Ardour, and they too play back sounds quite nicely (the sound is "grainy", though, perhaps I need to investigate the Low-Latency issues more, or increase the size of some buffer somewhere). I can send sound to the computer, and listen to that sound coming back from the computer (adjusting the level with the "line" level in Aumix, for example), but if I try to record that sound (in any of the applications I've tried, including all those listed above), with "record enable" selected in Aumix, I get no audio recorded (silent sound file). Also, I find it interesting to note that I can record-enable only one input source at a time (contrary to my old Media-Vision card). I'm assuming that's a function of the hardware, though and can't be fixed in software? Finally, we get to my questions: - Can someone point me in the right direction(s) to find a solution to this, so I can record audio (preferably from numerous sources) into my computer? I'll be perfectly happy with pointers to documentation (though I expect to get at least some to documentation I've already read, because I think I've repeatedly gone through all the documentation I already found myself), and suggestions to upgrade certain components. - I've tried to start Jackd at system boot, with the following command added to my rc.local file: /local/bin/jackd -d alsa -d cs46xx -p 512 & Jackd fails to start at that point (I'm afraid I haven't noted the exact error message, but I can make a point of doing so next time I reboot the system), but it does start when run manually from a root shell. Does anyone have any idea why jackd might not start at boot time, (perhaps the ALSA modules aren't loaded yet at that time)? If I understand my boot sequence properly, kernel modules are setup (via "depmod -a") before rc.local is run, so the modules may not be loaded, but they should by that point be loadable (they load automatically by the kernel in regular use). - Is it possible to build ALSA into the kernel? - on a slightly unrelated point, my new soundcard has a built-in synthesizer with at least some features I'd like to explore. Though I know this won't replace any of my hardware synths (or some of the software synths I've begun to play with), I'd like to play around with some of its built-in sounds, and probably use it (at least until I get something better) as my "preset playback" device, controlled from an external MIDI controller. Does anyone have suggestions for how I might go about that? (again, simple pointers to existing documentation would be more than appreciated). In case people are wondering about my specific intended application, I'd like to use a Roland Octapad to trigger percussion sounds from the soundcard's built-in synth. Thanks in advance for any pointers people can provide.... -- ---------------------------------------------------------------------- Sylvain Robitaille syl(a)alcor.concordia.ca Major in Electroacoustic Studies Concordia University Faculty of Fine Arts / Music Department Montreal, Quebec, Canada ----------------------------------------------------------------------

RE: [linux-audio-user] GM soundfont

by Reuben Martin

>As for good fonts... the big ones are pretty good, perhaps best is Fluid3 >(should be on hammersound), but that one is BiiiiiiiiG... Does anybody know where to get this Fluid III font? I have been looking for it and the ALL in ONE GM v1.1. They are nowhere to be found. There are lots of links to thesoundsite.net but that site seems to be defunct and Hammersound is a ghost town. I was able to get ahold of the MEGA Sound Bank v2.50 and it works quite well as a GS/GM sound font. You can get it at www.jchyun.com/~afterdan/MegaV25.rar If anyone knows where I can get the other two please let me know. Maybe we should see if gentoo would host these major sound fonts in portage... -Reuben

[linux-audio-user] novation remote 25 usb midi controller

by Eric Dantan Rzewnicki

I have not been successful in getting this keyboard recognized on the usb bus, let alone by the usb-audio driver. I'm going to see if I can get it working via straight midi into my ymfpci-based guillemot maxisound fortissimo. But, can anyone see anything else I can try?

[linux-audio-user] esd alsa ens1372 input monitor problem

by WR

Hi all, I'm having a problem trying to use esd with alsa and an ens1371 card. setup on boxes A and B: alsa-driver-0.9.5_r2 alsa-lib-0.9.4 esound-0.2.29 linux-2.4.21-rc4-aa1 On box A, I'm using a cmipci driver, box B, an ens1371. modules.conf has identical (except for driver id) content on both boxen. Everything alsa works on both boxen, playback and capture. Esound playback works on both boxen. The Problem: Esound esdrec works on box A, but not box B. On box B, esdrec times out and exits (yes, esd is running). It appears as though it looks to a port for capture data, sees none, then bails. Esound documentation is famously anemic, googling got me this far... Weird bit to me is that non-esound alsa capture is working fine on box B, it's just that esdrec doesn't seem to be addressing the right port. Anyone have any ideas? Like how does esdrec know which port to see, or how do I tell it to look in the "right place" for a capture stream...or how to set the "default port" so esdrec "just finds it" like on box A... Many thanks!!

[linux-audio-user] TerminatorX Scratching Problem

by Rainer Poisel

Hi guys! In the last days had some nice experience with terminatorX. I think it works well, but I don't know if the scratching is working correct. I started scratching and noticed, that the soundfile is played only forwards whatever direction the mouse is moved. When I set the "mouse speed" to a negative value soundfiles are always played backwards when scratching (holding the left mousebutton or pressing the "space"-key). Is it possible to play the soundfile in two directions? For example: mouse moving upwards while scratching -> playing forward mouse moving downwards while scratching -> playing backward Like a real turntable :) Thanks for any suggestions! Friendly regards, Rainer (rainer.poisel(a)kstp.net)
