Hi, sorry for the double post, but maybe a user knows the answer to this... What is the right way to call fst_init() ? I have installed fst-1.9 (tried 1.7 - 1.9), and it runs standalone and loads vst's OK. However, from within a simple 'hello world' app, when I call fst_init(), it causes a seg fault. The seg fault happens early within fst, in the 'wine_premain' code, at getModuleHandleA(). I have tried that trick of reserving and initializing 1,000,000 stack bytes (taken from from jfst_reserve_memory()). No luck. I really would like to get this working. Can you help? Thanks.

Re: [LAU] Aeolus, synthesized pipe organ

by lau＠ballen.fastmail.fm

Hmmm, the Jack I have here doesn't show any MIDI clients when I check the MIDI tab. At least, it doesn't show my keyboard. That should be listed as a client, yes? -------------------------------- Something I've noticed in the most recent qjacjctl is that there are now tabs for midi and for alsa connections. The devices that formerly showed up as midi now show as alsa. Is that possibly the issue? Also, I tried a new sequencer called non-sequencer which showed up in the midi tab and I couldn't figure out how to connect any inputs or soft synths as output. This might be a better question for the non-sequencer group. OTOH, what is the alsa/midi tab difference?

Making ecasound stop when only one chain is done?

by Ken Restivo

It looks like ecasound will continue processing until *all* the chains are done receiving input. Is there some way to get it to quit when only *one* chain is done? i.e., my little one-liner to use ecasound to feed JAMIN has a bug: it starts up perfectly at the start of the input file, but it sits there processing zeroes for as long as JAMIN is connected to the output chain. Not useful. -ken

Re: [LAU] clicking noise in all audio programswith new linux user

by Miguel Morales

I didn't know that audacity worked with jack. Have you tried to use the oss drivers instead of the alsa ones. Should be an option for this if you're using qjackctl. Do you get constant xruns when running jack? Perhaps you can post the ouput of jack when you run it and run a sound application that causes clicking. Also, make sure you hit reply-to-all when replying to the list. ^_^ On Thu, 2008-09-18 at 16:15 -0700, un records wrote: > Thanks for the response. how do you kill an artsd process? the > clicking when happens when i open jack, sound recorder, ardour, or > audacity. it's an irregular fast tick/clicking noise that changes > speed slightly when i change the latency rate. it doesn't happen when > i open a regular player like rythmbox or media player.

Rosegarden crashes - anything obvious to look for?

by Matthew Smith

Hi Folks Before I go through the painful process of collecting debug data and filing bugs against Rosegarden, I thought I'd see if anyone was familiar with the issues I am experiencing. Having finally got various external issues resolved, earlier today I attempted to record and play back a track on Rosegarden. I was using the current Gentoo ebuild, being the rather old version 1.5.1. I experienced a crash when trying to replay a track so upgraded to the latest masked ebuild, 1.7.2 - same issues. I have managed to get crashes when: 1) I attempt to play back a track. 2) I attempt to create a new track when there is a change to what is already there. So, I do 'new', I get 'the current file has been modified, do you want to save it?'. I say 'no', it crashes. When the crashes occur, I get a KDE crash handler pop up (I never even knew this was a KDE application) telling me that rosegardensequencer crashed and caused the signal 11 (SIGSEGV). After a short time, I also get a message from Rosegarden saying 'The Rosegarden sequencer process has exited unexpectedly.' Whilst these messages are popping up, Rosegarden disappears from the Connections window of qjackctl. The Rosegarden window itself, however, remains present. Is this a behaviour with which anyone else is familiar? Thought I'd ask around before running off and filing bug reports. Just in case it's relevant, I'm actually running the Fluxbox window manager, but KDE is installed and I run other KDE applications without issues - I use Konsole all the time as I have never found another terminal application that I like 1/1000th as much. Now up to about 20 hours total getting all this set up - almost makes me wish I'd stuck to analogue! (Or my Atari.)

Announce: Nama, an Ecasound-based recorder-mixer on CPAN

by Joel Roth

Hello LAU community, There is no shortage of recording and mixing software for Linux. Probably five or six that are based on Ecasound, with implementation languages including Lisp, Python, Tcl/Tk, Perl/Tk and probably others. Here is another one written in Perl. Nama is available from CPAN, included in the module Audio::Ecasound::Multitrack. The following command will install the software on most systems: cpan -i Audio::Ecasound::Multitrack Nama has tracks, buses, marks, a mixer and other conveniences allowing a person to record and mix using Ecasound without needing detailed knowledge of Ecasound chain setups. The program is a refactoring of Ecmd, with significant additions. Since I imported the original procedural code into git a year ago, I have introduced: - object-oriented code for buses, tracks, marks, etc. - YAML for .namarc and state save/recall - a command line grammar - help for text commands - default Tk GUI with a CLI in the terminal window - text-only mode for use without X - looping playback mode - support for Ecasound playat/select/audio_loop/reverse I have also found and closed many, many bugs. I have intended for Nama to be simple, predictable, hackable. and think I have achieved this, to some extent. Will appreciate any comments, suggestions, bug reports, patches or other feedback. I'd like to include special thanks to Kai, for Ecasound, to Brad Bowen for Audio::Ecasound, the Perl interface used by Nama. Joel -- Joel Roth

NtEd 1.2.1

by Bob van der Poel

I just downloaded and did a test run of NtEd 1.2.1 from http://vsr.informatik.tu-chemnitz.de/staff/jan/nted/nted.xhtml . I'm not involved in anyway with this project. But, I do encourage everyone to give this a try. And say nice things to the author! There are a few missing items which make a show stopper for me (mainly chord symbols), but progress is fast and the author tells me that my items are high on his list! I did a few midi file imports and was impressed with the speed and accuracy achieved. -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Aeolus, synthesized pipe organ

by Stephen Doonan

Aeolus is amazing! A totally synthetic pipe organ that sounds extremely "real" and beautiful, amazingly spacious, complex and full-bodied. I imported a MIDI file of Bach's Sinfonia to Cantata 29 into Qtractor, then connected the MIDI output of Qtractor to Aeolus, then played back the MIDI data while simultaneously recording the audio output of Aeolus responding to that MIDI data, back into Qtractor. Then I pressed some of Aeolus's stops while the file was playing and recording. I exported the audio as an OGG-Vorbis file directly from Qtractor. Here it is (no post-processing, no normalization, no editing nor effects at all) for anyone interested: http://flytrapranch.com/lau/aeolus_bach_sinfonia_cantata29.ogg What an amazing sound Aeolus has. Thank you so much, Fons (Adriaensen). It makes me want to buy this (if I had the money)-- 3-manual MIDI organ keyboard http://www.midiworks.ca/products/product_details.asp?productid=1&categoryid… (I wonder if the stops just beneath the keys can be easily programmed in Linux to correspond with stops in Aeolus) --and this-- MIDI organ pedalboard to standard specifications http://www.midiworks.ca/products/product_details.asp?productid=25&categoryi… Steve "Life does not give us a reason to live; we do." :-)
