Voice-to-drums in general and the Trigger LADSPA in particular

by Artem Vakhitov

Hi all, I am in search of a more or less easy way to do voice-to-drums - that is, to trigger drum samples (MIDI or otherwise) and control their volume (velocity) using my voice recorded from a microphone. Real-time is not necessary, and neither is multi-sample capability. The objective is to create more lively, groovy drum loops, which I can emulate with my voice. I tried using the Trigger LADSPA plugin but so far have not had any success with it. The output I get makes no sense to me, and the meaning of some parameters like e.g. threshold is unclear due to units chosen. Can anyone point me to any HOWTOs on using Trigger or describe the workflow in a few words? I would also like to know about possible alternatives to Trigger, including those for Windows. Thanks in advance, Artem Vakhitov

New Music: Shout - the song, that shall

by Julien Claassen

Greetings everyone! I finished a new piece last week and now I feel it may be time to post it here an hope, that you might enjoy it. http://juliencoder.de/nama/shout.ogg Or: http://juliencoder.de/nama/shout.mp3 Lyrics are here: http://juliencoder.de/nama/shout.html Or take a look at: http://juliencoder.de/nama/music.html This piece was my own first, real colaborative finished work. I'm very grateful to Silvia for the samples and much more than that. Thanks go to Joy Bausch for playing the ukulele and electric guitar. Last but not least thanks go to Mr. Bennett for playing the lap steel. It was wonderful work, that you all put into it. For the gear heads amongst us here is a list of used equipment in software and hardware. Linuxsampler for Drums, the Gigatron - thanks Q for a wonderful sample-library! -, the Rhodes and Wurlitzer e-pianos, the grand piano and the glockenspiel and trumpets. Fluidsynth was used for the bass and Beatrix had its own very organ-ic part in it. The Roland XP-30 for orchestral sounds, tron-dubling and windchimes. The Korg TR-76 for percussion and the bell-type sound. The Clavia Norlead3 for additional synth solo sounds and the Waldorf Microwave XT for sub-bass, the sparkly filter sweep and some additional synth backing. And of course my trusty old Clav. Nama did all the recording, processing and mixing/mastering! Thanks Joel for again investigating so much time and well-directed effort into Nama! It paid greatly for my work. Loads of LADSPA plugins of course for effects! Jconvolver and csound saw to some good reverbs and roomy impressions. Joy's guitar was also recorded in Nama, Mr. Bennetts lap steel was recorded and slightly preprocessed in Ardour. Soundstretch did some slight pitch correction on some of the guitars, because they wouldn't fit in some parts. Don't ask me why, they were OK, when they were recorded for one part. So that's about it. Comments and feedback is, as ever, welcome. Main thing though, that you might enjoy it.

Recommended USB interface with 2 XLR inputs?

by Mark Knecht

I apologize for cross posting. I asked this on Alsa-Users a couple of days ago but haven't received any responses. As it's about shopping I might do this weekend I figured I'd try here also. Thanks in advance. I'd like to pick up something to do simple mobile recording gigs with my laptop. It needs to be USB 2.0 based, have 2 XLR inputs, support headphone monitoring and preferably do 96KHz. The M-audio Fast Track Pro seems to come closest although as I understand it that device won't do 96K on all inputs and outputs at the same time. Not a huge deal but one tick against for that. What other devices do folks suggest I take a look at? Thanks, Mark

[OT] Fedora installation problem

by Dave Phillips

Greetings, Hopefully someone here has a similar setup and can help me out. Yesterday I installed a nice new Seagate 1T drive in my main machine. No problems with the physical installation, and the BIOS recognizes the drive. Next I installed Fedora 14 (x86_64) on the new drive. Again, no problems with the actual installation. On reboot my troubles started. I already have a system on this machine, an ancient 64 Studio 2.1 that works beautifully. Alas, it's very old, hence the second drive and new install. The old system is on /dev/sda1, with a swap at /dev/sda5. The new disk is /dev/sdb, and the new system is on /dev/sdb1 and /dev/sdb2. On reboot the machine went directly to the old grub menu for 64 Studio, which had no entry for Fedora. Before going further, I should note that I can't even mount the new disk while in 64 Studio. The older system doesn't recognize ext4 file systems, so I can't access the second drive. Okay, back to the boot. I used AV Linux to access the new drive and copied its grub entry to the old grub. Now when I boot I can see and select the Fedora entry, but I receive errors whether I attempt the boot from sdb1(hd1,0) or sdb2 (hd1,1). Sorry, I don't remember the error numbers, I'll get them and send them if needed. The installation media was without checksum errors, so the installed system should be ready to go. I just can't figure out how to boot into it from my existing menu. So my questions are: How can I get this machine to recognize the new installation ? Do I need to re-install and manually configure grub ? Is the 64 Studio boot loader simply too old to handle the new configuration ? The new grub menu.lst include a line "boot=/dev/sdb" but it appears to mean nothing to the older grub. I've pasted what I think are the relevant contents of the 64 Studio menu.lst at the end of this message, in case anyone cares to investigate and advise. I don't mind re-installing if necessary, but it would be nice to avoid that expenditure of time. Suggestions for fixing would be much appreciated. :) Best, dp -------------------- begin 64 Studio grub menu.lst ----------------------- title 64 Studio, kernel 2.6.21-1-multimedia-amd64 root (hd0,0) kernel /boot/vmlinuz-2.6.21-1-multimedia-amd64 root=/dev/sda1 ro vga=771 splash=silent initrd /boot/initrd.img-2.6.21-1-multimedia-amd64 savedefault title 64 Studio, kernel 2.6.21-1-multimedia-amd64 (single-user mode) root (hd0,0) kernel /boot/vmlinuz-2.6.21-1-multimedia-amd64 root=/dev/sda1 ro vga=771 splash=silent single initrd /boot/initrd.img-2.6.21-1-multimedia-amd64 savedefault ------------------- the new addition ------------------ # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

Linux/Musix/Debian on a UMPC

by Carlos sanchiavedraz

Hi all, dear LAUers. I've been doing some testing with Musix 3 beta (based on Debian Squeeze) installed on a UMPC like this one: http://www.myviliv.com/eng/product/x70ex.asp I try to use this gadget as live production environment (looper, multiFX for guitar, drum machine...), but there are some annoying things that keep me from having something really useful and stable. The main handicaps are: * touchscreen have a strange behavior: When you touch in a place the mouse pointer doesn't go there; rather it behaves as a regular mouse and I have to slide my finger until I get to the place or button wanted. Another issue is that it always perform left clic when you touch the screen, resulting in moving windows when you don't want to. So most of the time I have to connect a USB mouse to make some music. * wifi and blueetoth not working: Well, that is the some old problem: Musix is 100% free/libre so theres no driver that works, so I don't have apt-get chances to speed my work; just copying debs on a SD and then inserting the card on the umpc slot. Then there are other problems: no GPS for instance, but it has to do again with drivers. But those are the main problems I have to make Musix work properly and enjoy a full touch and record experience. I can do some music now but with a mouse and a keyboard. I've been doing my homework before posting this, doing some research on the web and trying things but no luck. I just wanted to know if any of you have some experience with UMPCs. Thank you in advance. -- Carlos sanchiavedraz * Musix GNU+Linux http://www.musix.es

Linux news in the current KWR Newsletter

by Jostein Chr. Andersen

Hi, In this week's newsletter, somewhere in the noise, it also says: "Togu Audio Line Native Linux VST Plug-ins updated". Well, I'm not a fan of using VSTs in Linux but I like to know what's going on, so of curiosity, I followed the links that showed up and ended here and there and not everywhere: http://distrho.sourceforge.net/ http://kxstudio.sourceforge.net/KXStudio:Applications And what did I find on the distrho file area? I found 64-bit stand alone version of the Arctican and TAL Plugins! They might be crap, but I don't think so, and I will test it now. And even more native free and commercial (and combinations of both) plugins, programs and goodies for Linux will come from everywhere - Life is good! :-) Jostein

Re: [LAU] Jackd no longer starts

by Robin Gareus

Hi David, "No longer starts" - what an euphemism. It crashes really bad. Well, given that it's from debian/unstable - maybe Adrian who packaged it (and is also subscribed to this list) has a hint. Otherwise open a terminal and type `reportbug jackd2`. "unstable" is - well - occasionally "unstable" :) A common cause for jackd segfaulting is that you one has some [self compiled] 2nd version of jack around on the system - but the trace does not support that..

Re: [LAU] [Ardour-Users] Portable non-firewire interface for Linux laptop w/ at least 8 mic pres?

by Harry van Haaren

Hey Paul, Linux Audio User is probably a more appropriate place to ask, as your question isn't really Ardour specific. Do you need low-latencies? If your *only* recording live gigs, then you can get away with huge latencies no problem... If you want low-latency 8 channel I/O, you're pretty much going to have to stay away from USB gear, there isn't enough bandwidth there to provide high sample-rate multiple channel audio. I will advise the PCMCIA / ExpressCard route with a firewire soundcard. My experiences with the Echo cards is fantastic, and they have an 8 channel-with pre's unit. Its definatly *not* budget though... http://www.echoaudio.com/Products/FireWire/AudioFirePre8/index.php Good luck, -Harry PS: Took the liberty to also sent this to the LAU list On Fri, Sep 30, 2011 at 4:21 PM, Paul Winkler <slinkp(a)gmail.com> wrote: > I want at least 8 preamps built-in (convenience and cost trumps > quality for me). > > Is there any such device?

"FLOSS your music"

by Roberto Suárez Soto

Hi, I'm doing a "feature" at my weblog, http://xouba.net. It's called "FLOSS your music", and will consist in a series of interviews to musicians that use FLOSS to make their music. That means you, my fellow linux-audio-user members :-) By now I've posted only the introduction ( http://xouba.net/post/10800887415/floss-your-music), to explain what it's about and why I'm doing it (besides the obvious fame and wealth). This weekend I'll post the first installment, featuring no other than Ken Restivo, who many of you will know from his postings here. I hope to make "FLOSS your music" a regular feature of the blog, if only because I had almost no content whatsoever there and this was a good way of promoting musicians that I like and FLOSS in general. Please, check it out. Comments and suggestions welcome. Thanks in advance, -- Roberto Suárez Soto

ubuntu vs arch

by Atte André Jensen

Hi A friend of mine who would like to use his new UA-25EX with ubuntu on his (i think) x200 (at least it's a 2.4Ghz dualcore 64 bit thinkpad with 6 or so gigs of ram). A very nice machine, that should be great for setting up a linux DAW. However I cannot make it run without x-runs (did the usual limits.conf dance). Whenever a window is dragged, or there's disk activity or something like that there's an x-run. He has two ubuntus installed, a 64 bit and a 32 bit (one is natty one is marverick, forgot which is which). Both systems (mis)behave the same. I tried running in openbox with pulseaudio killed, I installed the lowlatency kernel from Alessio Igor Bogani. I've been testing with ardour (which he's probably gonna use) and renoise (which I know best). The soundcard runs great on my dualcore 1.4Ghz x61s with arch. Any ideas would be highly appreciated. NB: Exact details regarding software or hardware can be provided, but the laptop is at his place... -- Atte http://atte.dk http://modlys.dk
