Hi, is there some way to find music made on Linux other than to go through this mailinglist? I found https://wiki.linuxaudio.org/apps/categories/music_made_with_linux but that seems to list only a fraction of what must be out there. Regards, Philipp

M-Audio Fast Track Pro: unreliable, distorted recording

by Lewis Pike

I'm the (un?)lucky owner of an M-Audio Fast Track Pro USB audio interface and I'm having some serious problems getting this device to record audio reliably under Linux. I've been using arecord and occasionally Audacity for all of my testing. My problem is this: Recording a take works about 80% of the time. In the remaining ~20% of cases, the captured audio is extremely loud with severe digital distortion. Once this problem shows up, it persists for any subsequent takes. The only way I've found to make the problem go away, at least temporarily, is to power-cycle the Fast Track Pro. I considered the possibility that this particular device might be defective, but it seems to work wonderfully under Windows. I'm calling out to other Fast Track Pro users in the hope that someone out there has encountered the same problem and better still, found a solution. Any suggestions at all would be greatly appreciated! .lewis

Using the Zoom H5 as a audio interface under Linux

by Faheem Mitha

Hello everyone, I've posted a question about using the Zoom H5 as an audio interface to sound.stackexchange.com, see https://sound.stackexchange.com/q/44364/24842 I've found scattered references to H5 working on Linux. One is on this mailing list - http://linux-audio.4202.n7.nabble.com/checking-passive-input-frequencies-on… But I can't get it to work. I've posted the contents of that question below. Any help would be appreciated. Please copy me on any reply. Thank you. Regards, Faheem Mitha ################################################################### I just purchased the Zoom H5 sound recorder, with the intention of using it both as a sound recorder, and also as a audio interface under Linux. My OS is Debian stable. Currently 9/stretch. Unfortunately, there is hardly any documentation on how to use it under Linux. I managed, by looking at the manual, to get my OS (Debian stable/stretch) to at least recognize the device. However, right now I'm not sure how to go with either Stereo or 4 Track. In both cases I end up with a screen that shows `USB AUDIO I/F XY5`, along with L, R, 1, and 2. But I see no motion in any of these. However, right now I'm not sure how to go with either `Stereo` or `Multitrack`. In both cases, it is clear that I need to go with the `Bus Powered` option. As mentioned in various places, if I choose `Stereo`, Debian thinks it is the H4, but with `Multitrack` correctly identifies it as the H5. In both cases I end up with a screen that shows `USB AUDIO I/F`, along with L, R, 1, and 2. But I see no motion in any of these. `lsusb` is showing the following: Bus 006 Device 006: ID 1686:01c5 ZOOM Corporation The syslog is printing a bunch of complaints: May 28 21:38:01 orwell kernel: [1505026.660071] usb 11-1: Warning!

May 28 21:38:02 orwell pulseaudio[6363]: [pulseaudio] alsa-mixer.c: Your kernel driver is broken: it reports a volume range from 0 to -1 which makes no sense. The H5 is also showing up in `pavucontrol`. The configuration section offers various options. I'm not sure which one to choose - the options are: Analog Stereo Output + Multichannel Input Analog Stereo Output Digital Stereo (IEC958) Output + Multichannel Input Digital Stereo (IEC958) Output Multichannel Input Off If I choose `Multichannel Input`, then it shows up in `pavucontrol` under `Input Devices`, but the volume level (or whatever it is called) for that device stays at zero. As it happens, I have another, regular mic plugged into my main (PCI Express) sound card (Xonar DX) right now, and that is responding fine. Also, I assume a working mic makes some noise, and the mics on the H5 are completely silemt. I'm sure I'm missing something obvious, so help would be much appreciated, bearing in mind my knowledge of things sound-related is very limited. And finally, can someone exactly what an "audio interface" means, exactly?

Zoom U-25 Audio Interface

by Max

Nowhere on this page it says that this device is class compliant, but it claims that there is no driver necessary for OS X and iOS which seems a good indicator for it. What do you you think of this interface? https://www.zoom.co.jp/products/production-recording/audio-interfaces/u-24-… 89 € there is also a version with digital interfaces: https://www.zoom.co.jp/products/production-recording/audio-interfaces/u-44-… 149 €

Yoshimi 1.5.8 released!

by Will Godfrey

V 1.5.8 - Kingfisher Bright flash of colour. The most significant changes in this release are all usability ones. At the request of one user (and agreement of several others) some of the microtonal settings are now MIDI-learnable, and appropriately highlighted. The CLI can now open and close instances, and switch between them. There is a new 'Solo' type 'TwoWay' this works in a similar way to 'Loop', but (apart from zero) values less than 64 step from right to left, instead of the other way round. The highlighting is also a bit better. Both 'Loop' and 'TwoWay' also have debounce protection of approximately 60mS. The CLI can now clear a part's instrument. A fairly obvious option that somehow got missed. In the Banks windows Instruments can now be swapped between banks and bank roots. Banks can also be swapped between roots. This is an extension using exactly the same controls as those already available for in-bank swaps. The latest feature is autoloading instances. With this enabled, any instance that was open when the main one is closed will be re-opened on the next run. If these instances were set for starting with their default state, then all those settings will be performed. Therefore, a very comprehensive and detailed session can be started with a single command! A lot of the documentation supplied with Yoshimi has been updated, including the Advanced User Manual. Yoshimi source code is available from either: https://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi Our list archive is at: https://www.freelists.org/archive/yoshimi To post, email to yoshimi(a)freelists.org -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

yoshimi does not function

by tom haddington

Hello, All-- I have been unsuccessful getting Yoshimi to work in Ubuntu Studio 18.04. This has been the case for the Yoshimi included in the distro, 1.5.7, and 1.5.8. When starting, the GUI and splash screen appear. The splash screen does not disappear, and the GUI is completely frozen. the command, "killall yoshimi," fails to eliminate the GUI. i'm sorry i can't be of more help, as no error messages have been generated. If anybody else has had this experience, i'd be happy to hear any solutions you've learned. Thank you! tom

yoshimi does not function

by tom haddington

>Are you running with jack or alsa? >What window manager are you using? i've been running with jack. i'm going to reboot and try with alsa. Since it's ubuntu studio, i'm pretty sure the window manager is xfce. i recompiled, with better success. Yoshimi did connect to jack. However, the GUI is still frozen. i'll reboot and try alsa.

[ANN] Qtractor 0.9.1 - A Pre-LAC2018 Release Frenzy Finale!

by Rui Nuno Capela

Hello again, The Pre-LAC2018 [8] release frenzy is now complete... Qtractor 0.9.1 (pre-lac2018 beta) is out! Change-log: - Displaying MIDI note(on) events as diamonds instead of simple rectangles (aka. Drum Mode) is now being introduced as an optional MIDI track property (Drums) and as a MIDI clip editor (piano-roll) visual option (cf. View/Drum Mode). - Extended multi-selection is now supported on all the Connections client/port lists, allowing for multiple (dis)connections at once. - Added LV2 UI sample-rate option support. - Always reset all internal dedicated MIDI controllers, eg. MIDI track volume (CC#7) and panning (CC#10), on Transport/Panic and after rendering export to aud1io (ie. Track/Export Tracks/Audio...) as needed to reset MIDI instrument plugins to nominal session state. - Fix, detect and preserve MIDI Bank-select method across MIDI track/clips editing operations. - Fixed MIDI track and clip note min/max display range while recording and also when duplicating tracks. - Added "All files (*.*)" filter to every file requestor dialog, wherever missing. - The tiny zoom-magnifier icons have been revamped. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
