I am in the process of creating a MIDI version of some string quartet music. So far I have been using VPO solo strings sounds, but these are not very satisfactory even after editing the .sfz files to the best of my (limited) ability. VPO has some great sounds for string sections no doubt, but for solo instruments it is not so good. I downloaded an sf2 version of some solo string sounds and converted them to sfz, but found that they were very synthetic sounding. I have also downloaded the Philharmonia Orchestra samples. These are fairly comprehensive and sound good, but unfortunately the samples themselves are very short (typically only 1 or 2 seconds long), and I haven't been able to make satisfactory loops with them. Can anyone suggest where I might find some good quality solo string sounds? Ideally, as well as normal bowed and pizzicato sounds, I would like natural and artificial harmonics and open (i.e. unstopped) string sounds.

SoundTracker 1.0.4 released

by Yury Aliaev

Hi there, I have released SoundTracker v1.0.4. Comparing to the last pre-release, 1.0.3-pre2, it contains several important bugfixes, so I recommend everyone to upgrade. Its main revolutionary feature is a facility to process samples by any external program that can communicate through STDIO. The interaction with such a program is described used XML specs (not documented yet, but the comprehensive example: much of SOX functions, is included), so one need not recompile ST, only restart after adding new specs. Other main features of the 1.0.4 release are: * General: - Full-screen mode - Volume of all samples of an instrument / all samples in the module can be set to a value, not only gained. Also all samples panning can be adjusted. These functions can also modify the explicitly given values of volume / panning of notes in patterns - Improved compatibility with FastTracker, also MOD files are played more correctly - Unused patterns are listed in the Pattern Sequence Editor - Sampling rate can be specified while saving a sample as WAV - New module optimizer with many control parameters * Track Editor: - Moving notes up / down is implemented * Sample Editor: - The whole sample is drawn after recording - Exponential / reverse exponential volume fade transients * Instrument Editor: - Envelope inversion and shifting is implemented You can find more new features in NEWS file.

Programmable Audio Workshop (PAW-23), Lyon, France, Dec. 2, 2023 + Bonus Workshop on Faust -> FPGA

by Stéphane Letz

The Programmable Audio Workshop (PAW) is a yearly one day FREE event gathering members of the programmable audio community around scientific talks and hands-on workshops. The 2023 edition of PAW is hosted by the INRIA/INSA/GRAME-CNCM Emeraude Team at the Marie Curie Library of INSA Lyon (France) on December 2nd, 2023. The theme of this year's PAW is "Artificial Intelligence and Audio Programming Languages" with a strong focus on computer music languages (i.e., Faust, ChucK, and PureData). The main aim of PAW-23 is to give an overview of the various ways artificial intelligence is used and approached in the context of Domain Specific Languages (DSL) for real-time audio Digital Signal Processing (DSP). As a side event, we will also be organizing a "Faust/FPGA" workshop on Dec. 1, 2023 in Lyon. More information as well as the full program of these events are available at: https://paw.grame.fr We look forward to seeing you there and we remain at your disposal if you have any questions. Stéphane for the PAW-23 Team

Regarding the last point: I find that using the right/left arrow buttons almost always causes sfizz to crash! Previously I was usng the lv2 version of sfizz; I have now tried the vst3 version, but with similar results. So I decided to try to install the latest git version of sfizz, using your very helpful step-by-step instructions. Unfortunately the first cmake command produces this error: Package 'jack', required by 'virtual:world', not found I certainly have the jack server running on my computer, and QjackCtl shows it to be working OK. No package called simply 'jack' seems to exist in the regular Ubuntu Studio repositories, so I'm not sure what to do about it. Any suggestions? David

Confused about sample rates.

by Bill Purvis

I mentioned in a previous email that I've switched to Pipewire on my laptop. It works fine with most things - I use Audacious to play CDs, and Firefox seems happy enough to play things from You-Tube or BBC. However, when I try to run GrandOrgue I get confusing messages, saying: Error: No sound output will happen. Samples per buffer has been changed by the sound driver to 512. Under jack, I had been running at 44100sps, with 2 buffers of 1024 samples. QJackCtl shows this as still being in force, though whether this is what pipewire is actually doing I don't know. Changing setting in QJackCtl to 512 spb gives a message which suggests that pipewire is still expecting 1024.

Finding status of jack server with pipewire

by Bill Purvis

Hi, I'm putting together a digital organ using GrandOrgue and Jack, I've had to adapt a program called ttymidi to convert serial input from Arduino scanners to Jack which passes it on to GrandOrgue. It all works fine until I try to polish up the pwoer-on sequence. If I start the modified ttymidi code before jack has got going it falls over. I want to be able to test out my modified code on my laptop, as I only get access to the organ occasionally. Unfortunately I recently switched my laptop to use pipewire instead of pulseaudio (for general usage, such as watching web videos). That got sorted out, but when I came to testing my code, it seems to set up the connection to jack even when I've stopped jack (actually jackdbus). Is this because pipewire is intercepting the requests (jack_open_client(...))? I tried adding an input port, and this seems to connect OK, and the client appears on qjackctl's connection graph, despite qjackctl saying that jack is stopped! Is pipewire doing a complete replacement for jack? I can't find much on the web other than initial install and setup, not much about how it works. I can probably sort out the above problem next time I can access the organ, which doesn't need pipewire or pulseaudio, so it will just be running jack, but I am curious to know more about what is going on. Anyone on this list actually part of the pipewire team? Bill -- +----------------------------------------+ | Bill Purvis | | email:bill@billp.org | +----------------------------------------+

DAW Project?

by Lorenzo Sutton

Just read about this: https://github.com/bitwig/dawproject As with many of these 'standardization' efforts success might depend on adoption, but it's an interesting initiative, so we will see what happens :-) Lorenzo

[LAA] Anklang 0.2.0 Released

by Stefan Westerfeld

Anklang version 0.2.0 is released. Anklang is a digital audio synthesis application for live creation and composition of music. It is released as Free Software (MPL-2.0) and runs under Linux. The real-time sound engine is implemented in C++, the UI runs in Electronjs, Firefox or Chrome. Assistance with development, porting or creative efforts is very welcome. Anklang provides a MIDI sequencer, Undo/Redo capabilities for note editing, real-time synthesis, and support for CLAP plugins. The source code and binary packages are available here: https://github.com/tim-janik/anklang/releases/tag/v0.2.0 The project website with further resources is at: https://anklang.testbit.eu/ ======================================================================= This release has significant improvements to audio synthesis capabilities and user interface. The documentation has been improved in several places, and automated generation was integrated into the CI. Audio synthesis enhancements include support for new CLAP (draft) extensions, such as transport information and file references. We now support non-linear mappings for BlepSynth ADSR times, and a new audio plugin Freeverb by Jezar at Dreampoint was added, with fixes to the damping mode in the original version. Additionally, a Jack PCM driver based on Stefan Westerfelds’ code was integrated. Performance improvements were achieved by adding a new optimizing memory allocator and supporting low-latency scheduling via sched_* or RtKit. Saving projects will now automatically create backups of recent versions. The user interface has also seen significant improvements in this release. These include context help via F1 key in various UI components, fixes to mouse wheel sensitivity for modern browsers, improved tooltips and note editing in the piano roll. The UI can now be zoomed via new menu entries, the color palette was updated, and integration of TypeScript annotations allowed improving the UI JavaScript code quality. In terms of packaging, AppImage builds saw major compatibility improvements, and we increased the frequency of Nightly releases, building from nearly all significant trunk merge commits. We aim to generate more regular releases in the future instead of having lots of Nightly builds between regular releases. -- Anklang Free Software DAW: https://anklang.testbit.eu/
