[LAU] [ANN] Vee One Suite 0.9.18 - A Fall'20 Release

by Rui Nuno Capela

Boring news ahead... Once again, the 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here released onto the wild, just for the (Northern) Fall/Autumn'20 season... Boring as hell, they still feature the same two kinds of deliverables: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Change-log: - Upstream package naming for the JACK standalone and LV2 plugin deliverables are suffixed to '-jack' and '-lv2', respectively. - Fixed note-off effectiveness when DCA is disabled (idle). (applies to <a href="#samplv1">samplv1</a> and <a href="#drumkv1">drumkv1</a> only) - White keys on the virtual piano keyboard are now fully highlighted. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. Boring but true: **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.18 (fall'20) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

[LAU] PSIndustrializer 0.2.7-pre1 released

by Yury Alyaev

Hi all, I have made a first preview of Power Station Industrializer v0.2.7 You can download it here: https://sourceforge.net/projects/industrializer/files/ What is new in psindustrializer-0.2.7: Improved accuracy of setting some parameters Rendering and playback can be interrupted. Playback can be retrigged at any time Both actuation and sampling nodes are made selectable (Hint: you can use this facility to generate great stereo samples. Although PSIndustrializer doesn't support direct stereo samples saving yet, you can manually save two samples with the same model and parameters, but different sampling nodes. Then map them to right and left channels and have fun!) Bugfixes As always, bugreports and feature requests are welcome! Regards, Yury.

[LAU] Calculating absolute played(!) volume

by Jeanette C.

Hey hey, for a project I am wondering, if the absolute output volume of a pair of headphones, directly connected to a soundcard, can be gained from the settings? I have a Delta 1010. Inside alsamixer the volume for the DACs is set in dB. Is there a straight relationship between these settings and a connected output device? My pair of headphones, IIRC, have a resistence of 60 Ohm. Any help is appreciated. A good pointer will do. If there is a method without special measuring equipment, I'd be happy. If not... So be it. Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c But now I'm stronger than yesterday <3 (Britney Spears)

[LAU] JACK and S/PDIF sync'ed delta 1010 cards: bad vs. evil?

by Jeanette C.

Hey hey, I have two M-Audio Delta 1010LT cards, sync'ed via S/PDIF. Two ALSA devices were created to sum the inputs and outputs respectively. On top of that JACK is running. Now, I noticed that it is a decision between two problems that I face: if they are correctly sync'ed, some system services regularly freeze. This includes the networ, the Braille display (connected via USB). If, as has happened before, the setup isn't remembered correctly and the S/PDIF sync is not made, occasionally the cards begin to have input problems. The sound suddenly degrades with an effect like bad resampling (decimation effect). I have had these cards running for a long time in this constellation, but only in the past few years these problems cropped up. I have changed the distro from Debian to Arch Linux. On Arch I have tested the system for realtime operation several times, using the realTimeConfigQuickScan script. Could this be a kernel issues? Some ALSA update? Or a question of the kernel patches that one is running? I am running the following two kernels now: 5.6.19-rt12-1-rt or 5.8.14-arch1-1 The last time I ran Debian it was on a 2.6.3x kernel, IIRC. Any suggestions, apart from don't use your cards at once, would be very much appreciated. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c But now I'm stronger than yesterday <3 (Britney Spears)

[LAU] Album: Crazy drive

by Jeanette C.

Hey hey, my latest album Crazy drive is out. At some point all the songs would have gone past. But this time the album is hosted on my own server, you will find the songs and OGG and mp3 format, as well as m3u playlist for both formats. http://juliencoder.de/nama/crazy_drive/index.html This is possibly more in the way of a sampler than an album as such, but one sorted with intent. :) The genres span electro, synthpop, Drum&Bass, electro-rock, oldschool techno(esque), Dubstep and timeless synth-based music. :) On the Linux side the pieces involved everything from Csound (effects, drums and other sounds), to Yoshimi to LinuxSampler. I used both commercial and non-commercial samples - more of the latter actually -, as well as self-sampled sounds and self made patches for Yoshimi. On the hardware side there were analogue, hybrid-analogue and a wavetable synth and a Clavinet. :) There's currently no sampled-based hardware in the setup. I hope you enjoy - some of - the music.

[LAU] [Music] Endless day (direct link to private server OGG audio)

by Jeanette C.

Hey hey, seeing that Youtube poses an issue for some, which I can understand on many levels, I have uploaded an OGG file of the song to my own website: http://juliencoder.de/endless_day.ogg This file will remain there for a few weeks.

[LAU] [Music] Endless day (borderline synthpop)

by Jeanette C.

Hey hey, this song has been about 20 years in waitiing. It is utterly, unashamedly "feel good" pop. The idea came to me whilst on holiday by the sea, in summer. I neither had the synths nor the harmonic ability to write it then. But first the song itself: https://youtu.be/p1HAU-YmT8k Ever since the latest addition to my instrument family - TR-808 clone - I toyed with recording it. But then a few days I hit on a few nice chords and on Atte's live modular jam "click": https://youtu.be/9YgUOOxyTNA Atte kindly gave me permission to cover/interprete the gorgeous main melody line from that piece and so I had a chorus. :) No prizes - or should there be? - for guessing which song I listened to a lot that summer. :) Feedback is ever is welcome, but foremost: enjoy and relax!

[LAU] SoundTracker 1.0.2 first pre-release

by Yury Alyaev

Hi all! Today I have finished a large amount of work: support of user actions logging in SoundTracker. This means that almost all operations can be undone / redone. Before this I have redesigned the sample editor. Although these are not all improvements scheduled for 1.0.2 release, I would like to start testing of the above two features. So I have issued the first pre-relase available as usual at https://sourceforge.net/projects/soundtracker/files/ I invite everyone to test this and send me bugreports. But I'd like to warn, that this pre-release couldn't be pretty stable and can occasionally crash. If you are familiar with gdb (GNU debugger) please compile ST with CFLAGS=-DDEBUG and after crash explore the core file with gdb and send me the backtrace. Regards, Yury.

[LAU] [LAA] Mamba - Virtual Midi keyboard for Jack Audio Connection Kit release 1.6

by Hermann Meyer

Hi Mamba release v1.6 is out Mamba is a Virtual MIDI keyboard with some extended, unique features. Virtual MIDI Keyboard Mamba comes with some predefined key-maps, qwertz, qwerty, azerty(fr) and azerty(be), but you could define your own with the included Key-map Editor as well. Beside the computer keyboard and mouse, Mamba supports jack MIDI in and ALSA (seq) MIDI in. Output goes to jack MIDI out. Every channel use it's own Colour to display the played Notes per channel. 16 Channel Live MIDI Looper: To record a loop, press "Play" and then to start recording press "Record". To stop recording press record again. Playback will start immediately. The first recorded channel will become the Master channel. This one set the time frame for all later recorded loops. For the Master Channel the recording time will be stretched/clipped to match the next full beat time point. To record a new loop, switch to a other channel, select your instrument and press "Record" again to start recording. The later recorded loops will be synced to the master loop. When the recording time extend the absolute Master loop time record will be switched off. Absolute time is not bound to the loop point, so you could record loops crossing it. You could as well stop recording by press "Record" again before the time expires. Each Channel could be cleared and re-recorded separate at any time. even when you press "Record" on a already recorded channel, it will be cleared before recording starts. You could record the connected input device or play the Keyboard itself. MIDI File player You could select a MIDI file with the File Selector. It will be loaded in the play buffer of the first channel, regardless how much channels it use. You could use then channel 2 - 16 to record your own playing into it. To play along with it you could use any channel. A loaded file will become the Master channel for the looper. To save your work just go to Menu -> "File" -> "Save MIDI file as", select the path and enter a file name. If you don't give the usual file extension Mamba will add the extension .midi befor save it. Fluidsynth When you load a Sound-font via the Menu -> "Fluidsynth" -> "Load Sound-font" Mamba will start the Fluidsynth engine and do the needed connections so that you could just play along. Menu -> "Fluidsynth" -> "Settings" will pop-up a new Window were you could select the Instrument for the channel and do settings for Fluisynth Reverb and Chorus. All your Settings will be saved on exit, so on next start you could just play along. Mamba is released under the BSD Zero Clause License license The GUI is build on libxputty - A damn tiny abstraction Layer to create X11 window/widgets with cairo surfaces https://github.com/brummer10/libxputty To build Mamba from source, the following dependencies must be meat. * libfluidsynth-dev * libc6-dev * libsmf-dev * libcairo2-dev * libx11-dev * liblo-dev * libsigc++-2.0-dev * libjack-(jackd2)-dev * libasound2-dev So, here is the project page: https://github.com/brummer10/Mamba and here you'll find the last release: https://github.com/brummer10/Mamba/releases/tag/v1.6 regards hermann
