Re: [LAU] FOSS DAW recommendations

by James Harkins

Hi, So... now I feel like the careless person who flicked a lit cigarette into the vat of kerosene and just walked away :D I'm actually a regular user of Audacity, but I think it's more of a sound file editor than a DAW. I love it for trimming, normalizing, fade in/out, noise reduction and glitch repair. I don't love it for multi-tracking, cross-fading and tempo-synced editing. If Audacity has true nondestructive, clip-based editing, I haven't found it. To me, it's like: If you want to trim your nails, you use a fingernail clipper. If you're doing topiary, you use other tools, up to and including a chainsaw. Audacity is the fingernail clipper -- pretty close to ideal for the things it does well, but it doesn't do everything well. I don't often need multi-tracking, cross-fading or tempo-synced editing, but when I do, that's when I want a DAW. There, it seems like it's pretty much Ardour or go home. Contrary to some suggestions, I'm not scared of routing dialogs or submix channels. (I particularly enjoyed the comment about being "savvy enough to operate Supercollider" LOL :D .) It worries me a bit when David K. says "It's when you start editing that things get awful" -- because, tight, tempo-synced editing is exactly the time when I want clips whose edges you can edit easily and instant cross-fades. Ages ago, I used Digital Performer on Mac, and courses at my school now tend to use Cubase (the latter of which... sheesh, Steinberg are really tone deaf about interface design). I know my way around. Complexity is fine. Stability is a higher priority than a simple interface -- given the choice between a beautiful, easy interface that crashes often and a complex interface where things "just work" once you learn them, I'll go with the stable, complex interface, every time. hjh

[LAU] Solved: Firewire on current laptop

by Bill Gribble

Hey, I had been keeping around an oooold Dell laptop just because it had an Expresscard slot that I could use to talk to my FireWire audio interface. I was considering jumping ship to a new usb interface since I haven’t been able to find a smaller sized laptop with any FW or expresscard interface. But I saw some mentions that maybe a USB-C/Thunderbolt 3 port, which is available on more laptops these days including my HP, might work. Following the trail I tried out a frankencable approach: Thunderbolt 3 to Thunderbolt 2 adapter, connected to Apple Thunderbolt 2 to FireWire adapter, connected to a FireWire cable with the right ends to plug into the Apple device and my FireWire device. It works! The only tricky bit is to make sure udev knows to allow hotplugged devices on the Thunderbolt port, which it doesn’t by default. That done, my interface appears to Jack as an ordinary FireWire device. If I was traveling with it I might encase the first 12 inches in heatshrink tubing or duct tape or something, but for now I am just glad not to have to give up my firewire mixer which I am sort of attached to. Thanks, Bill Gribble

[LAU] FOSS DAW recommendations

by James Harkins

Asking which DAWs are good, especially for mixing, audio editing and stability. I'm not a heavy DAW user. Most of my work is electronic music live performance with SuperCollider. Because my usage is rare, I've shied away from Bitwig, and even Ardour. I use SuperCollider a lot, and I pay for it by answering support questions and contributing. I don't want to pay money for something I'll use, oh, maybe 10-15 hours in a whole year. I've had bad experiences with qtractor crashing. Never used the non- suite. I installed Rosegarden at one point, but never kicked the tires for audio. Did I miss anything? Thanks, hjh Sent with AquaMail for Android http://www.aqua-mail.com

[LAU] Can you experts answer questions about a MIDI a composer sent me?

by david

Sending this separately to linux-audio-users and rosegarden-user lists, so apologies in advance if anyone sees it twice. It's by a fractal music composer, Albrecht Niekamp. The MIDI is generated somehow from fractal images he makes using Fractint and a complex formula framework he created. I don't know how he generates it - perhaps he has his own program that transforms his fractals into MIDI files. The piece is called Taiko Trance. I imported it into Rosegarden, found 10 tracks in it, assigned each to a Taiko Drum soundfont I found on the internet and recorded it. You can find it here in MP3 and WAV format, plus his original MIDI file and my Rosegarden project file: http://clanjones.org/david/albrecht/ I like the way my rendering sounds. But here's his response to my rendering: > So sorry, David. I dont recognize my music > The rhythm is completely gone, the speed is wrong too > and there is one instrument that does not belong there. > > Even the "syncopated" Hirajoshi scale melody is there > [when he plays his original composition using his software > on his system] this has completely vanished in your version. > > Re your remark about surround audio: the phase shifting I applied > does something very similar - moving voices to rear and front. > This effect too has vanished. He listens to his pieces through a "30-year old Marantz 4-channel" system, so I can't duplicate that listening experience if his hardware is adding things to the sound (such as the front/rear positioning). In subsequent emails, he mentioned an 11th track in the MIDI. As the Rosegarden project shows, I only found 10 tracks. He's working on uploading a recording of what he hears when he plays his MIDI file using either MS Media Player or Winamp Midi on Windows 10. (According to him, Winamp Midi lets him apply "interactive realtime effects" such as changes in front/rear positioning. So until I hear what he's hearing, I'm lost.) But I wonder - could someone knowledgeable check the MIDI? From some of the subsequent discussion, I'm wondering if he's somehow got different tempos for each track? (He refers to "phasing patterns"). Or there are other things about his MIDI that Rosegarden just can't handle properly? What other sequencers could I try on his file? Thanks. -- David W.

[LAU] Scaling governor goes back to 'powersave' a bit after boot up

by jonetsu

Hello, I have set the scaling governor to 'performance' by doing: echo -n performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor For all 4 CPUs. After reboot, the scaling governor indeed shows: % date Sun Oct 22 08:53:49 EDT 2017 % cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor performance performance performance performance But then shortly thereafter: % date Sun Oct 22 08:54:06 EDT 2017 % cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor powersave powersave powersave powersave Which mechanism decides long after boot that the scaling governor should be modified and how to tell it that 'powersave' is not what we want ? Cheers.

[LAU] qjackctl freezing desktop

by Fons Adriaensen

Hello all, After an update of Archlinux + fluxbox, starting qjackctl freezes the desktop. The mouse pointer still moves, and I can switch to tty1 (Ctl+Alt+F1) and kill qjackctl, restoring normality. Looks like qjackctl does an XGrabServer and then waits for something that never happens. All hints to fix this are welcome ! Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

Re: [LAU] How to get aubio commandline tools?

by James Harkins

> From: worik > > ubuntu 17.10 it is aubio-tools OK, I'm on 16.04 and unlikely to upgrade soon. (I can't afford much downtime, so I tend to stay on stable versions.) So, you're saying the aubio-tools package in 17.10 includes the command line executables, but the same package for 16.04 doesn't? That's fine if that's the situation -- then, I just know I have to build it myself (which doesn't look too hard). hjh
