Re: [LAU] Freecycle segfaults on 64studio (64 bit)

by Norval Watson

Yes Emiliano I just d'loaded freecycle and got basically same result on single-core amd3000, debian sid amd64 PS: any chance of getting the Freewheeling deb you built from svn? I am stuck... Norv Hi all, Is anyone able to run freecycle on a 64bit installation? Here the program opens and I select "Open wave": it shows the file selection dialog but when I press "OK" the program segfaults. Here's some output from gdb: Trying to apply envelope in central wave zapWaveCanvasBuffers() in wavecanvas (parent [central wave]) Buffers zapped in small wave zapWaveCanvasBuffers() in wavecanvas (parent [small wave]) Buffers zapped zap buffer 0 done zap buffer 2 done zap buffer 4 done +++++++init buffer type: 0 no: 0 length: 32208000 zap buffer 0 done init buffer 0 done +++++++init buffer type: 4 no: 1 length: 32208000 zap buffer 2 done init buffer 2 done Trying to apply envelope Program received signal SIGSEGV, Segmentation fault.

ableton live through wine

by Atte André Jensen

Hi Does anyone here have any experience with running ableton live through wine? Some googling suggests it might be possible, but I'd like to know from people with hands on experience... -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

Question about fitting all this MIDI music stuff together

by david

I have a laptop with the Intel integrated audio, which lacks any form of hardware MIDI synthesizer, so I use fluidsynth. I use Rosegarden for my sequencer. I just got an E-Mu 1x1 USB<>MIDI cable to hook in my Yamaha keyboard. Let me see if I've got this whole thing straight. Keyboard talks to Rosegarden. Rosegarden talks to fluidsynth (and to the keyboard, if I want). Fluidsynth talks to JACK, JACK talks to ALSA, ALSA drives the sound hardware. So I play something on the keyboard, it bounces through the above chain (with of course the manual step of playing the composition from Rosegarden if I'm using Rosegarden), and sound burbles joyously from the laptop sound output. Yes? Then, also, I can have other programs (like PD, CSound, amsynth, ALSA Modular Synth, Audacity, etc) hook into this chain somewhere, too? Do I connect everything together using JACK? I'm asking all this because my present music setup on the laptop is sort of hodgepodged together - somehow it works, but I'm not sure how, or if it's even working the best way it could be. I'm not planning to switch distros, boring Debian testing works for the vast majority of my needs (music writing is a smallish part of that). Later, I'll tackle setup/configuration of the desktop computer, which has more horsepower and a real sound card, and perhaps set that one up with an audio-focussed distro. But for now, just focusing on the laptop. Thanks. IIRC, I also owe Julien some song lyrics, too - sorry, Julien, it's on the to do list! -- David gnome(a)hawaii.rr.com authenticity, honesty, community

How clean is direct digital out

by Mark Constable

I have this onboard audio "card" and snd-rate shows it does 44100-192000 on playback (perhaps capture as well)... nVidia Corporation MCP67 High Definition Audio (rev a1) My question is if I playback a 44.1 khtz CD track out through the S/PDIF on the motherboard will it be modified in any way or would the values from a CD, mp3 or wav pretty well go directly out the S/PDIF ? The reason I ask is that the analog audio output is medicore (but better than previous onboard audio I have had access to) but perhaps the optical S/PDIF out would be as good quality as any high end card (seeing the MCP67 handles 44100 natively) ? --markc

[ot]: literature on arrangment/composition

by Julien Claassen

Hello! Does anyone know some nice internet literature on composition? to be more precise I'm looking for a book/guide to arrangements/harmony. I found a practical book on composition, as used in German, the act of creating a piece, general temporal structure, musical figures and gestures, but it seems to lack the special aspect I'm looking for. If anyone knows something helpful, please tell me. Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

All i want for the holidays is a SPL Meter. Please help me choose a good one.

by Bearcat M. Sandor

Folks, When my mate asked me what I wanted for the holidays, i looked over at my audio system and said "I want a sound pressure meter." So i'm looking around and of course the price range runs from cheep Radio Shack digital one to hundreds of dollars for professional Class 1 models. I'd like to spend around $100 - $125 and get an accurate meter so i can adjust my speaker positions, room treatments etc. So i'd like accuracy to at least 1 db or more, a display that will give me 1 decimal place, a bar that will show me levels over time. I'd love to be able to get the data in to my computer and have an gnu/linux program to display it, but that's probably past the $125 mark. My speakers have a range of 22hz - 35 khz +-3 db so if i could detect that range that would be great, but that's probably also over the $125 mark too. Any recommendations? Thanks a lot. Bearcat M.

linking soundcards

by Atte André Jensen

Hi I'm building a live performance using chuck. We need to have both click + the actual audio produces, routed to either a headphones mixer or the PA. I could of source live with mono and pan the click to one channel and the music to the other, but stereo is better... The problem is twofold: 1) Can I link the onboard soundcard and an usb soundcard so that they appear to the system as one four channel device? 2) Can I address each of these outputs (or sets of stereo outputs) from chuck? BTW: I don't need super low latency and I only need playback. The laptop is gonna be an IBM x61 running ubuntu and the usb card is an Edirol UA-1A. Thanks in advance for any response! -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
