Hello! I just discovered two problems with ardour: 1. If you run the autogen script the -gui and -ksi options are exchanged. Where it says -gui it says something like libs="libs_base ksi" and in the ksi-case it wants to include the gui-libs. 2. The next thing something running ardour-ksi. I've jack-0.7.3 and I seemed to fullfill all the other dependencies. But now when I try to start ksi it says: /usr/local/lib/ardour/ksix: relocation error: /usr/local/lib/ardour/libardour.so.0: undefined symbol: _ZTI8QMThread So and that's all. this ardour version is from tuesday morning. Any ideas about the second problem?

[linux-audio-user] Developers: how to sync PCM to Midi?

by Denis de Leeuw Duarte

Hello folks, I'm writing a realtime audio tool and I'd like to pick your brains on the following: say my app is rendering some sound and a midi event comes in, at what point in time should the resulting effect occur in the rendered audio stream? The obvious solution would be to measure world/system time at the moment playback is started in my application. If a midi event then comes in, I can subtract this start time from the midi event time. I am however afraid that my timing will then drift each time an underrun occurs. I'm pretty sure applications like terminatorx, sweep and a host of others solved this problem before me so if anybody knows the answer to this, please let me know! Regards, Denis p.s. I use JACK for audio output but the solution really should be independent of this. --------------- www.cyozlab.com _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.

[linux-audio-user] Cactus Data Shield copy controlled cd's

by Maarten de Boer

Hello, A collegue of mine just bought the new Radio Head CD, Hail To The Thief. As the box says, this CD is "Copy Controlled". Some searching on the web revealed that it using so called Cactus Data Shield 200 protected, which means deliberate errors on the cd, that most (not all!) CD players deal with correctly, but cd-rom readers don't. So, what if you want to play your "CD" on a computer. Well, the CD also includes a data track, with a MS Windows (yeah..) application. However! This application does not play the CD audio but a compressed format also included on the CD! Another interesting issue is that the fake errors might actually cause problems when some real errors occur on the CD, that normally would have been corrected, but not anymore in combination with the fake errors. Obviously, all this is completely unacceptable, so I advice you to never buy a Copy Controlled CD. If you have bought one, bring it back to the store. They have absolutely no reason not to give you your money back. (From the web: 'Philips controls the CD standard and their spokesman says: "Any changes that put a disc outside the CD standard result in a disc that should no longer be described or marketed as a CD." Philips, because of conformity issues, has warned the record labels that the discs are actually not compact discs at all, and must bear warning labels to inform consumers.'). I'd add that stores should then not be allowed to sell these CD's in a part of the store that says "Compact Discs" Not that I did manage to play the CD with Linux. My very old (>6 years) SCSI cd writer has been able to read the copy protected CD with cdparanoia. but... in the left channel, every 5.8 sec some values are distorted: about 10 groups of 1 to 3 samples in a row get an extreme value (not always the same, but near maximum). I wrote a small application that corrects those distorted values (linear interpolation with the surrounding samples). I assume this information is legal, because it is only to play the cd, not to copy it. Maarten

[linux-audio-user] horgand v1.0

by holborn

Hi! New Release : horgand 1.0 News in v1.0 (19/06/2003) ------------- -Added small auto-accompaniment, Looped Drums and a Bass line in a wave table way. -added chord recognition -some free drum loops and bass samples. -bugs solved in DSP effects, now more stereo, minus noises :-) First i want to say something, personally i dont like any kind of auto-accompaniment, sequences, organs, because many people use it for work, and this is not good for the musiciens. In fact i wonder the day when the musiciens dont want to record anything, anymore. Only write the papers, and play live, that's music. Please read the Readme file for how to add new loops and other questions. REQUERIMENTS: * FAST COMPUTER * LINUX * ALSA * JACK * FLTK 1.1 Web Page : http://personal.telefonica.terra.es/web/soudfontcombi/ Josep

[linux-audio-user] Jack 0.70.4 crashes on connection

by Mikhail Ramendik

Hello! I am trying to use jack 0.70.4. The reason for the old version is simple - rosegarden 4 0.9.1 fails to build with 0.72.4. But before I can use rosegarden, I need to run fluidsynth. And I can't get as far as this. Connecting fluidsynth's jack ports to the alsa ones causes an immediate jack crash! Any advice on getting this to work would be very appreciared! Deteils follow. I run three root terminal windows (rxvt or xterm - does not matter). In one of them I start jackd; in the other, fluidsynth; and in the third, try to get ports connected. Here is all that I do, and the output I get. In the jackd terminal: === [root@ramendik misha]# jackd -d alsa -d hw:0 jackd 0.70.4 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support loading driver .. creating alsa driver ... hw:0|1024|2|48000|swmon|swmeter|rt open port alsa_pcm:capture_1 has mixdown = 0x4001da28 port alsa_pcm:capture_2 has mixdown = 0x4001da28 port alsa_pcm:playback_1 has mixdown = 0x4001da28 port alsa_pcm:playback_2 has mixdown = 0x4001da28 starting engine === in the fluidsynth terminal: === [root@ramendik misha]# fluidsynth -a jack YamahaGrand_Adcock.SF2 fluidsynth version 1.0.2 Copyright (C) 2000-2002 Peter Hanappe and others.

Lost the connection to the JACK server === What "zombified" means is clear - it also happens if I simply Ctrl-C the jackd terminal. So it looks like a jack crash, not a fluidsynth one. Help... Thanks in advance for any tips. Yours, Mikhail Ramendik
