setting up a Behringer BCF2000 for use with ardour

by uhoh

i've followed the online ardour manual section 10.2, but it isn't working. manual page shows the bcf showing up under MIDI in qjackctl Connect window, but for me it comes up under ALSA. i tried various combinations conncections to/from ardour from qjackctl but to no avail. i'm using debian lenny on amd64 with ardour compiled from source (since it's not in the debian distribution). i have the bcf2000 connected through usb and it's showing up fine in /proc/asound/cards. any help would be greatly appreciated.

Jack frequently crashes when running LinuxSampler + Qsynth

by Guru Prasad B. R.

Hello everyone, This is my first post on this list. My compliments & gratitude to everyone working towards Linux Audio! I'm a semi-pro musician (keyboardist + singer), and for the past few months have been working on a linux-based setup for live performances. Here's what I use: 1. LinuxSampler, which loads my main piano sample. I depend on this sample throughout the performance (it happens to be a 888 MB sample). I also have additional pianos and drums loaded on. The other pianos are more of a backup, but I almost never use them. Drums are triggered by a Korg NanoPad. 2. Qsynth, on which I have a few string soundfonts on different channels, totalling less than 20 MB. Typically these are layered on top of tmy main piano sample. 3. I use a python script based on Mididings to for midi processing, to achieve splits and layers, and map hardware controllers. 4. JackMixDesk as a software mixer, to adjust the levels of the various layers, and vocals. 5. Jack-Rack, loading Calf reverb plugins + amplifier, for vocals. 6. Everything started through QJackCtl. I use a Casio keyboard as a Midi controller (thru USB) and a Korg NanoKontrol. I recently migrated from a Celeron laptop to a core2 duo Macbook, both running Ubuntu 9.04. On both, I've been using the builtin soundcards. After migrations, there's been a persistant issue with Jack's stability: -After a few minutes of playing on the keyboard, the sound from the samples become horribly distorted, crackly, buzzy and tinny (sorry, thats the best description I can give!). -At the instant of this 'crash', this appears in the Messages window of qjackctl: "subgraph starting at LinuxSampler1 timed out (subgraph_wait_fd=31, status = 0, state = Finsihed, pollret = 0 revents = 0x0) -When I restart Qsynth, it says "Qsynth1: Failed to create te audio driver (jack). Cannot continue without it". Upon restarting Jack, everything's happily back to normal, until the crash happens again. I checked with the system monitor, and the resource usage is well within limits - max of ~80% CPU/core, and less than 50% of RAM being used at any point of time. Needless to say, this effectively rules out using my linux system as a live performance tool. Like all stage musicians, I place a VERY high premium on stability. But I would love to have a completely open-source setup - so any pointers/help would be greatly appreciated! Cheers, Guru

Re: [LAU] M-Audio FastTrack Pro, all four outputs in jack

by Nicanor Garcia

Hello Dan, I also use the M-Audio FastTrack Pro, and I also have the same problem A while ago I tried the solution you found with .asoundrc but it never worked, so I let that issue archived to fix it later as I didn't really need that functionality... until now. I'm getting some basic recording equipment and I need to use both outs. Have you had any luck with that solution, or have you found any other solution. If not, let's work together to find a solution, as I consider the FastTrack a good audio interface, and the only thing missing to get all the functionality in Linux is the four outs issue. Saludos from Colombia. Nicanor García O.

NVIDIA proprietary driver and jack

by Frank Kober

This is somewhat unsolicited, but I thought I share this in case it is not known, since I was puzzled for a while... I have set up a new (more powerful core 2 duo) laptop system recently, and it's got an NVIDIA card. The vesa drivers only gave me suboptimal display resolution, and the nv driver did not work at all so I wanted to stick with the proprietary nvidia driver. I had many xruns especially when there was little activity on the desktop and when the audio applications were minimized. Then I found that in the nvidia control panel that comes with the drivers there is that clock settings option where you toggle between 'adaptive' and 'prefer maximum performance'. And all of my problems disappear when the GPU clock is set to 'prefer maximum performance'. So it was not the CPU clock powersave (cpufreq) settings, but the GPU clock that was causing the trouble. (my yoshimi problems before were not related to that). So I have a solid jack-1.9.3 running with a standard desktop kernel at 8ms latency without drawbacks in video performance. :) Maybe someone has/will run into those problems, so i just leave the info here. Regards Frank

Multiple soundcards with JACK (on Debian)

by rosea grammostola

Hi, I have two soundcards $ lspci | grep audio 00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) 02:03.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 [Envy24] PCI Multi-Channel I/O Controller (rev 02) But I can't choose in qjackctl (interface) I like to have the maudio as default (ICE1712), but want to be able to use/choose the onboard too. Thanks in advance, \r

Re: [LAU] [Zynaddsubfx-user] yoshimi bug fixes

by Frank Kober

Hi Cal, I just tried your patch. With four layers enabled playing different synth types PAD, SUB and ADD in chords I think I can affirm that the crackling is gone, we'll wait for Will's and Adriano's report, but from my side: many thanks :) Frank --- En date de : Ven 16.10.09, cal <cal(a)graggrag.com> a écrit : > De: cal <cal(a)graggrag.com> > Objet: Re: [LAU] [Zynaddsubfx-user] yoshimi bug fixes > À: linux-audio-user(a)lists.linuxaudio.org > Date: Vendredi 16 Octobre 2009, 12h01 > Folderol wrote: > > [ ... ] > > Hmmm > > V 16 no clicks :) > > V 23 clicks (but not shown Xruns) :( > > I can't figure this out.

How to use Linux VST (SoundCrab)?

by Jonathan E. Brickman

SoundCrab comes as a .so file, a native Linux DLL. It is called by its maker a VST, so I tried it with the VST host included in AVLinux, 'vsthost'. It gives the below. I have tried copying soundcrab.so to /usr/local/lib/vst, but there was no change in result. What is the best method to use? J.E.B. jeb@jebspc:~/Desktop/VST$ vsthost soundcrab.so Returning file identifiers: QSTwMe2iCe1CDtqWf1l0rEup RemoteVSTClient: executing /usr/local/lib/dssi/dssi-vst/dssi-vst-server -g soundcrab.so,QSTwMe2iCe1CDtqWf1l0rEup DSSI VST plugin server v0.986 Copyright (c) 2004-2008 Chris Cannam Loading "soundcrab.so"... dssi-vst-server[1]: not found in /usr/local/lib/vst/soundcrab.so dssi-vst-server[1]: not found in /usr/local/lib/vst/soundcrab.so dssi-vst-server[1]: not found in DLL path dssi-vst-server: ERROR: Couldn't load VST DLL "soundcrab.so" Plugin server timed out on startup: No such device or address vsthost: bailing out
