Over the last few weeks I've been going through Yoshimi with a fine-tooth comb bug hunting, with some success (and much frustration). I'm doing this on my 'office' computer which is running debian testing on a 64bit AMD - fairly similar to my music machine. During the week, I did an update via synaptic and now suddenly when I try to compile Yoshimi it fails to link, giving the message: Linking CXX executable yoshimi /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libfltk.a(Fl_x.o): undefined reference to symbol 'dlsym@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [yoshimi] Error 1 make[1]: *** [CMakeFiles/yoshimi.dir/all] Error 2 make: *** [all] Error 2 will@debian:~/yoshimi_20130926/src$ The investigating I've done suggests that something has changed in cmake so that yoshimi now needs a more 'correct' identification of fltk. I sort of gathered that cmake.txt was the place to look, but doing so tells me nothing. fltk is there but none of the information really makes sense to me. Although I don't like doing anything experimental on my music machine, I can do that for the time being as it is running an earlier version of the distro but presumably the new requirement will eventually hit the stable releases. Can someone help me sort this out please. P.S. A current version of ZynAddSubFX doesn't have this problem, but the build structure is now very different so I couldn't find any points of comparison. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[ANN] Radium 1.9.31

by Kjetil Matheussen

Radium 1.9.31 is a big release with many new features and bug fixes. 1.9.31 is the first release with Pd embedded. Pd is a " Real-time graphical dataflow programming environment for audio, video, and graphical processing." (http://puredata.info/) Pd embedded in Radium has got approximately the same features as Max for Ableton Live. (https://www.ableton.com/en/live/max-for-live/) Screenshot: http://folk.uio.no/ksvalast/radiumpd.png Video 1: http://folk.uio.no/ksvalast/radium_pd.ogv Video 2: http://folk.uio.no/ksvalast/radium-pd-invertnote.ogv Radium homepage: http://users.notam02.no/~kjetism/radium/ Most important changes 1.9.30 -> 1.9.31: * New demo song: BlowFish! Made by www.magnetophon.nl * Save hashmap elements in sorted order so that songs can more easily be compared textually * Menu entry to show name of all included pd externals * Help menu options to edit keybindings and menues * Song comment dialog * Fix "Switch Window Configuration" menu option * Removed "Error. y2>=window->height: ..." error. Just print to stderr instead. * Removed the "Something strange just happened in the function Blt_markVisible" warning (print to stderr instead) * Option to set number of scrolls per second. Scrolling too often can be tiresome for the eyes. * Make it easier to connect objects and see connections in the mixer, plus adjust object sizes * Patchbay sound object * Fix crash loading Soundfonts in the Fluidsynth and Sampler instrument * Show stars around filename if theres unsaved data * When quitting or loading, only ask sure/yes/no if edited since last save. * Change "Set Patch For Track" to "Set Instrument For Track" in the instruments menu. The word "patch" should not be exposed to the user anymore. * Be able to load files with DOS char set * Changed internal radium block size to 64 (similar to Pd) * Sending note events between sound objects (green lines) * Enable undo for on/off effect controllers * Pd extended is included as a sound object. 921 externals are included. GUI is working. Several instances is working. Can be used to write both audio effects and note effects. * Fix qt paths on Archlinux (Javafant/archlinux) * Many minor bug fixes

midi in python, 2 pygame.midi questions

by Atte

Hi I'm working on some midi thing in python. I had a hard time finding a decent library. In the past I used PySeq alot, but that's tricky to install and seems un-maintained. So I settled for pygame, and it's going ok. However: 1) In PySeq I created inports and outports that were visible for instance in qjackctl. Is that possible in pygame (currently I just connect to the right client from python)? Why would I prefer one over way over the other? 2) If I unplug the connected client or press ctrl-c (my preferred way of exiting my programs) I get: PortMidi call failed... PortMidi: `Bad pointer' type ENTER... How can I exit a pygame program cleanly without getting errors? 3) One of the things I'd like to do I automatically connect to any client that shows up while the program is running and *gracefully handle it* if clients disappear while the program is running. I imagine the first is a matter of scanning for clients every now and then, but right now I get the error mentioned in 2) if I pull the plug on a device that my program is connected to. Any ideas how to handle this? Any feedback is greatly appreciated! -- Atte http://atte.dk http://modlys.dk

No audio with Debian Wheezy (+ 3.10 bp kernel) on Intel Haswell processor...

by dafreedm＠gmail.com

Hi, I'm running stock Debian Wheezy (7.1) --- except for a kernel upgrade (3.10-0.bpo.2-amd64) from Debian backports --- as well as XFCE, on a couple different hardware configs. However, I'm struggling to get audio to work properly on my new Intel Haswell board. (1) On a Thinkpad x220: Audio works great, out of the box (2) On a Supermicro X10SLQ (Q87 chipset) with Haswell i4770S: Audio doesn't work at all --- no audio at all comes out of standard rear headphone jack. (NOTE: Supermicro website identifies audio capabilities as provided by onboard RealTek ALC888S chipset, but lspci [below] instead identifies Intel HDA audio, courtesy of Haswell. I worry that this might be an issue.) Could this be an issue with the kernel, or should I be looking elsewhere. I was under the belief that 3.10 (unlike the 3.2 kernel that shipped with Wheezy) had fairly comprehensive support for Haswell in general! Some more information is attached below... I don't have much experience trouble-shooting audio problems, so I appreciate any suggestions / pointers. Thanks! ---------------------------------------------------------------------- guest@haswell:~$ lspci -v | grep -i -A8 audio 00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06) Subsystem: Intel Corporation Device 2010 Flags: bus master, fast devsel, latency 0, IRQ 52 Memory at f0534000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Kernel driver in use: snd_hda_intel -- 00:1b.0 Audio device: Intel Corporation Lynx Point High Definition Audio Controller (rev 04) Subsystem: Super Micro Computer Inc Device 0654 Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0530000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Kernel driver in use: snd_hda_intel guest@haswell:~$ lsmod | grep snd snd_hda_codec_realtek 32712 1 snd_hda_codec_hdmi 31720 1 snd_hda_intel 35718 5 snd_hda_codec 122850 3 snd_hda_codec_realtek,snd_hda_codec_hdmi,snd_hda_intel snd_hwdep 13189 1 snd_hda_codec snd_pcm 68525 3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel snd_page_alloc 13018 2 snd_pcm,snd_hda_intel snd_seq 45186 0 snd_seq_device 13176 1 snd_seq snd_timer 22773 2 snd_pcm,snd_seq snd 53068 19 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_hda_codec,snd_hda_intel,snd_seq_device soundcore 13026 1 snd guest@haswell:~$ dmesg | grep -i sound [ 2.007991] input: HDA Intel MID HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:03.0/sound/card0/input6 [ 2.008079] input: HDA Intel MID HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:03.0/sound/card0/input7 [ 2.008131] input: HDA Intel MID HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input8 [ 2.034368] input: HDA Intel PCH Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input9 [ 2.034620] input: HDA Intel PCH Line Out CLFE as /devices/pci0000:00/0000:00:1b.0/sound/card1/input10 [ 2.034834] input: HDA Intel PCH Line Out Surround as /devices/pci0000:00/0000:00:1b.0/sound/card1/input11 [ 2.035018] input: HDA Intel PCH Line Out Front as /devices/pci0000:00/0000:00:1b.0/sound/card1/input12 [ 2.035199] input: HDA Intel PCH Line as /devices/pci0000:00/0000:00:1b.0/sound/card1/input13 [ 2.035383] input: HDA Intel PCH Rear Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input14 [ 2.035565] input: HDA Intel PCH Front Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input15 guest@haswell:~$

A music quality article of interest (OT but not much)

by Pete Wright

I go all he way back to when music came over the AM radio, clipped, attenuated, stomped, squashed, and premasticated. The "stereo" of my day wasn't stereo (yet) and we called it Hi-Fi (for high fidelity) and we built our own amps or assembled Heathkits. So now (according to Steve Guttenberg) we are back to stomped and pre-chewed, except around LAU where we all still roll our own one way or another.

Fwd: [estudiolivre] Fwd: Lives: some beginner questions

by Daniel Roviriego

---------- Forwarded message ---------- From: salsaman <salsaman(a)gmail.com> Date: 2013/10/1 Subject: Re: [estudiolivre] Fwd: [LAU] Lives: some beginner questions To: estudiolivre(a)lists.riseup.net Hi Rosea, the best solution is not to encode to any format, just leave the clips as a "set". You can do this either by File -> Close/Save all Clips, or when exiting the application (LiVES will prompt you for a set name). When you save the set there is a checkbox "auto load this set when LiVES is started". If you check this, then the next time you start LiVES it will ask you if you want to reload the set. You can have any number of sets on the disk, so any time you can just load the one you want to use. (File -> Load set). You have to close the current set before you load a different one though. You can also start up LiVES with any set, by using: lives -set <name_of_set> See also in the manual: http://lives.sourceforge.net/manual/LiVES_manual.html#section4.7 Hope this answers your question. Good luck !

RME Fireface UCX with new firmware finally recording in debian

by drz

My dear Linux Audio Users I upgraded the firmware in my Fireface UCX yesterday. In the Release Notes I saw this...: "Fireface UCX: V 42/220/23/4: Class Compliant: full 18 channels, choice of 2 playback routings (C8/CA)" I thought I should give it another try in debian Linux wheezy as they changed something in the class-compliant mode. And what can I say ... its now recording in Audacity in stereo (channel 1+2). So if I plug in two mics, I can record! yippieh So heres what I did: (I hope I remember all steps) 1.) I followed some Howto, I cant remember where I found it, but I created a .pulse folder in my ~-Folder Then I pasted these files in the ~/.pulse Folder: File default.pa: load-module module-native-protocol-unix load-module module-jack-sink channels=2 load-module module-jack-source channels=2 load-module module-null-sink load-module module-stream-restore load-module module-rescue-streams load-module module-always-sink load-module module-suspend-on-idle set-default-sink jack_out set-default-source jack_in #I think I will play with module-jack-source channels=2 to get more input # channels File daemon.conf: sample-format = float32le default-sample-rate = 48000 realtime-scheduling = yes exit-idle-time = -1 2.) I logged out of KDE and logged back in 3.) Then I started qjackctl In the options I chose Input and Output Device hw1 Fireface UCX 4.) Next I started jackd, by clicking start. 5.) I chose a CC setup in the Fireface UCX I created before in Totalmix to have Phantom Power on both Inputs, by searching SU and then choosing the right seetup number (refer to the Firefox-manual). 6.) Finally I started Audacity and ..... it was recording both inputs Yeah! If I check 96000 Hz in jackd-options, audacity shows 96000 Hz, too, and if I export it as a wav-file the metadata tells me its 96 kHz, wow! And it sounds like it, too ;) greetz & have fun drz

avw.lv2 0.1.5

by Aurélien Leblond

Hi all! A quick e-mail to annonce the latest version of the lv2 set avw.lv2. As a reminder, this set of plugins is designed for Ingen to create modular synths. Inside you can find VCOs, LFO, VCA and all the main modules to create Modular Synthesizers. Parts of these plugins are a port of the internal modules of the great Alsa Modular Synth. In this specific version, I focused on bug fixing and usability. I added as a well an Amplitude Modifier and a plugin to transform VC to Controls. This way, you can for example use the LFO (VC amplitude -1/1), use the Amplitude Modifier to transform the amplitude of the LFO to 1000/3000, use the plugin VC to Controls and plug all that into a Low Pass Filter. Finally, with the source code comes two example that you can load straight away into Ingen to try the plugins out. To download: http://sourceforge.net/projects/avwlv2/files/avw.lv2-0.1.5.tar.gz/download I really hope you will enjoy those, and I would be really interrested to get any feedback! enjoy :) Aurélien
