Hi, is it still active here? I’m trying to locate some help for developing a basic subtractive synth for Linux with support for sound patches. Can someone point to any primer material? And What dev libraries for synth development are essential? Thanks in advance M - http://sound7.co.uk <http://sound7.co.uk/>

[LAA] [LAU] 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

spectmorph-0.5.1

by Stefan Westerfeld

spectmorph-0.5.2 has been released. The two new main features (synchronizing morphing with the song tempo and positional play) are explained here: https://youtu.be/6E4HClXdV_Y If you haven't watched our video tutorial for the instrument editor added in 0.5.0, you can do so here: https://youtu.be/JlugWYPDp84 Overview of Changes in spectmorph-0.5.2: ---------------------------------------- * Support bpm/beat synchronization for LFO - new presets using beat sync LFO: Mars / Saturn * Add WavSource custom position playback mode * New Instruments: Sven Ah / Ih / Oh (another male human voice) * Store data in XDG directories on Linux: - move ~/.spectmorph directory to $XDG_DATA_HOME/spectmorph - move ~/SpectMorph directory to $XDG_DOCUMENTS_DIR/SpectMorph - create $XDG_DOCUMENTS_DIR/SpectMorph directory when needed (on write) - backward compatibility: use ~/SpectMorph if it already exists * Bump number of control inputs from 2 to 4 * Implemented midi CC control for smjack (General Purpose Controller 1..4) * Fix crashes caused by dangling MorphOperator pointers * Fix loading floating point wav files * Minor fixes and cleanups 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 3 Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS users. Here is a quick overview of how you can make music using SpectMorph. - VST Plugin, especially for proprietary solutions that don't support LV2. (Available on Linux and 64-bit Windows/macOS) - LV2 Plugin, for any sequencer that supports it. - JACK Client. 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. -- Stefan Westerfeld, http://space.twc.de/~stefan

[LAA] [LAU] Mamba - Virtual Midi keyboard for Jack Audio Connection Kit release 1.5

by Hermann Meyer

Hi Mamba release v1.5 is out Mamba is a Virtual MIDI keyboard with some extended, unique features. So it could load/play and save MIDI files, it visualize the played files on the keyboard, were it use a unique color for each channel. you could visualize a single channel, or all together at once. It could record your playing and play it back as endless loop. You could record a loop for each channel while the other channels still play. Note, that the loops don't be synced. So this is not for composing classic music, but to create Psychedelic Trance floors. Truly you could save your work as MIDI file and rework it in the DAW of your choice. It will record as well all incoming MIDI messages, so you could use it as well to record your external MIDI controller. // <https://de.wikipedia.org/wiki/Psytrance#Psychedelic_Trance_und_Psychedelic_…> Mamba also includes support by fluidsynth, you could load a soundfont and directly play along. It include controls for the fluidsynth reverb and chorus, and a selector to select a instrument/patch for each channel. Mamba will keep it's settings, so once a soundfont is loaded, on the next start you could just play along with the keyboard. You could load a new soundfont at any time. To use it as a plain MIDI keyboard again, you just need to exit fluidsynth via the menu and connect Mamba with the synth of your choice. 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 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/v1.5 regards hermann

Hi Mamba release v1.4 is out Mamba - Virtual MIDI keyboard and MIDI file player/recorder Mamba is not only a Virtual MIDI keyboard, it's also a MIDI looper. It allow you to record, for example a bass loop on one channel and then play along on a other channel with a piano or whatever. You could save your loops to MIDI files if you wish, in any case, Mamba save your last record and load it on the next start on default. Mamba is also a MIDI visualizer, it shows not only what you play, it shows as well incoming events. It also allow you to load MIDI files, play them in loop and show the output on the keyboard. You could select which channel you would monitor on the keyboard. You could as well monitor all channels at once. Mamba includes also support by fluidsynth, you could load a soundfont and directly play along. Mamba will keep it's settings, so once a soundfont is loaded, on the next start you could just play along with the keyboard. You could load a new soundfont at any time. You could as well exit fluidsynth to use Mamba as plain Virtual MIDI keyboard with the synth of your choice. 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 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/v1.4 Mamba features # Virtual Midi Keyboard for Jack Audio Connection Kit <https://jackaudio.org/> # Including NSM <https://linuxaudio.github.io/new-session-manager/> support # Including gettext <https://www.gnu.org/software/gettext/> localization support # Including fluidsynth <https://github.com/FluidSynth/fluidsynth> support # Soundfont loader for fluidsynth # Channel selector # Bank and Program selector # Keyboard mapping for qwertz, qwerty, azerty(fr) and azerty(be) selectable from menu # Keymap Editor to setup a custom Keymap # PC Keyboard mapping selector from C0 to C4 # Pitchbend, Balance, Modwheel, Detune, Expression, Attack, Release, Volume and Velocity controllers # Sustain and Sostenuto switches # Connection management Menu # Support Midi-file load, save, record and play in loop # BPM controller for playback speed # Support Midi Beat Clock for playback speed # Midi Through: forward midi input to output # Midi input highlighting # Resizable to a full range 127 key view # Load Midi-files on command-line # Support jack_transport to start/stop Midi-Loops regards hermann
