spectmorph-0.6.0 has been released. The new main features are: - SpectMorph now provides a CLAP plugin. - A filter with different filter modes was added. - A new, more flexible modulation system was added. - SpectMorph now provides visual feedback for modulated parameters. Video Tutorial for 0.6.0: https://youtu.be/watch?v=scKrf0o6e6k What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS (Intel and Apple Silicon), with CLAP/LV2/VST plugins. Under Linux, there is also JACK Support. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. List of Changes in SpectMorph 0.6.0: ------------------------------------ #### New features * New, more flexible modulation system * Added filter with different filter modes * Provide visual feedback for modulated properties * Provide signed .pkg installers for macOS (Intel and ARM) #### CLAP Plugin * Provide CLAP Plugin * Support for per-voice modulation * Support timestamped modulation/automation events #### LV2 Plugin * Support LV2 on all platforms * Fix crashes triggered by Carla (absolute_path/abstract_path returning NULL) * Support newer LV2 development headers #### Minor Changes * Support "Velocity" as modulation source * Make pitch bend range configurable * New Presets with filter: "Cheese Cake Bass", "Liquid Silver" * Sort midi events by timestamp to workaround Bitwig bug * Sliders now support shift+drag for fine editing * Support for Apple Silicon * Avoid crashes if XOpenIM / XCreateIC return NULL (#15). * Fix statically linked plugin data directory location (works in flatpak apps now). * Add dockerized MXE builds for windows, bump compiler version to gcc-12. * Bump minimum C++ standard to C++17 * Fix build on RISC-V (#13) * Use GitHub CI for Linux, macOS and Windows * Change license from "LGPL v3 or later" to "LGPL v2.1 or later". * Minor fixes and cleanups #### Internals: Properties * Add generic property handling * Simplify load/save/gui for properties * Support modulatable properties using ModulationList * Add gui for editing property value and ModulationList * MorphPlan is no longer ref-counted, just one instance per Project * Introduced MorphOperatorConfig objects for cleaner/faster parameter updates #### Internals: Filter * Add two filter types: "Ladder" and "Sallen-Key" filter to output operator * Integrated PandaResampler for SIMD 4x filter oversampling * Support modulation with high time resolution for filter #### Internals: UI Toolkit * Support multiple update regions in UI toolkit * Optimize drawing for UI toolkit * Support "software sprites" for efficient visual feedback * Map Ctrl+Left Click to Right Click on macOS #### Internals: Optimizations * Pass wav set pointers (instead of strings) to morph linear/grid/source. * Avoid fmod() for phase truncation. * Build using -ffast-math * NotifyBuffer: fast dsp thread -> ui thread notifications (no malloc in dsp thread) * Avoid allocations in dsp thread in many cases (retrigger, noise decoder process) * Support optimized SIMD code on ARM (Apple Silicon), code from Peter Johnson (#11) -- Stefan Westerfeld, http://space.twc.de/~stefan

[LAU] Mamba goes Micro-tonal

by Hermann Meyer

Hi I've just implemented Scala support into Mamba (Virtual Midi keyboard and Midi Live Looper for Jack Audio Connection Kit) Those interested in microtonal tuning's could load a Scala tuning file now via drag n' drop or via the file manager. The Keyboard layout will reflect the tuning ratios of the loaded file. regards hermann

[LAU] QMidiArp 0.7.0 released

by Frank Kober

Hi all, The 0.7.0 release of QMidiArp now ships with new LV2 plugin UIs based on the robtk toolkit by Robin Gareus for the first time. The UIs will get installed in parallel to the original X11 UIs that were still based on Qt. The new robtk plugin UIs are independent of Qt and do not link to system-provided libraries whose API changes frequently. For building them you need some new fellows though: glu, gl, cairo, pango and pangocairo headers are now required. The cmake or configure script will tell you. Note that with the new UIs, arpgeggiator patterns cannot be edited. But, the provided presets can of course be selected in the LV2 host. If needed you can add new patterns for the LV2 Arp module manually by editing the <lv2dir>/qmidiarp_arp.lv2/qmidiarp_arp.ttl file, presets are at the end of the file. All other modules and functions should work as before. Enjoy Download https://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.7.0/qmidiarp-0.7… Github https://github.com/emuse/qmidiarp Website https://qmidiarp.sourceforge.net/

[LAU] ANNOUNCE: Jeanny's Hits 1.0 - big drum sample pack (including extensive 808 samples)

by Jeanette C.

Hey hey, I'd like to announce the release of Jeanny's Hits 1.0, a drum sample pack: http://juliencoder.de/sound/jeannys_hits-1.0.zip The sounds cover a variety of genres and needs, and certainly pack a punch. :) The samples are sourced from Csound (Lawn kick 1/2, Lawn snare 1/2 and more) as well as from analogue hardware instruments, including the Behringer RD-8 (analogue Roland TR-808 clone), the semi-modular Behringer Neutron and Aurturia MiniBrute 2S as well as the Dave Smith Instruments (Sequential Circuits) Prophet-12. the most extensively sampled is the RD-8 with different settings, including a tuned kick over one octave. No digital post processing on that! The samples are stored as WAV files, stereo, 16BIT, 48kHz and come with SFZ wrappers to be easily loaded into many samplers. Almost all samples come with round robin and/or velocity layers. The analogue sounds were mostly edited within Csound and Nama using a mix of LADSPA plugins. Any donations are very much appreciated, if you can afford it and think the collection is worth it. Find details on that in DONATION . More info on sound groups (kits) and the simple SFZ files you can find in the README file. The pack is released under the GPL version 3, which should allow you to use it within many different productions under a variety of commercial and non-commercial licenses. Best wishes and enjoy, 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 Can't you see I'm a fool in so many ways <3 (Britney Spears)

[LAU] ECHO Audiofire12

by Mac

I have 2 ECHO Audiofire12 units. They are in pristine condition and I just have no use for them. Linux audio still supports firewire (I think), so they may be of use to someone. If anyone is interested, you pay the shipping and duty. They are in the USA. Admins: Feel free to remove this if it breaks the rules. Regards, Mac

[LAU] Jack setup

by Bill Purvis

Hi, I'm struggling with my jack setup again. I am running Devuan Chimaera and the MB has a builtin sound chip (ALC887) which works using just ALSA. I had an Audigy sound card, and Jack worked OK with that. Longer term, I'll by using a UDAC8 USB sound module, but it's not here at present, and I expected to be able to simply switch the Jack output device from the Audigy to the ALC877. I can play a test file through ALSA (aplay test1.wav) which is OK, though a bit low volume, but when I reconfigure jack to use it, I don;t get any system output on QJackCtl, and jack-play gives no sound, not surprising if there's no port to connect to. Last resort is to put the Audigy card back in for now. Bill -- +----------------------------------------+ | Bill Purvis | | email:bill@billp.org | +----------------------------------------+

[LAU] Help !

by Fons Adriaensen

Hello all, Since four days now, the melody I try to reproduce below is haunting my brain. Don't know how i picked it up. It's a popular classical piece which I have heard many times, from the romantic period and as I remember it, for string orchestra. But I can't find out what it is. Tried some of the 'find a melody' sites, no succes. 6/8 (or maybe 3/4) - = continuation of previous note by 1/8 | A-- G#-- | A---- B | C-- B-- | Bb----- | | Bb-- A-- | G----- | F-- G Bb A | Bb----- | Can anyone identify this ?? Many thanks ! -- FA
