This release focuses on workflow improvements, clearer signal routing,
and new creative options.
### New Features
- **Drag & Drop Processing Chains**
- Filter and Machine chains can now be reordered via drag and drop
- Machine chain changes trigger a full key cache rebuild
- Filter chain changes apply immediately in real time
- **Reverse Sample Playback**
- Samples can now be played in reverse
- Fully integrated into the existing voice and filter pipeline
- **New Machine: Vintage (TimeMachine)**
- A new offline machine focused on temporal character and coloration
- Operates during key cache generation
- Designed for non-destructive experimentation with timing and feel
---
### Architecture & Workflow
- Clear separation between **offline machines** and **real-time filters**
- Deterministic signal flow from sample → machine → key cache → voices →
filters
- Improved internal consistency and predictability
---
### Documentation
- Added a new [**Loopino
Wiki**](https://github.com/brummer10/Loopino/wiki/User-Documentation)
- User-facing documentation covering:
- Sample loading and destructive trimming
- Machines vs Filters
- Signal flow and processing stages
- Documentation aims to be precise, technical, and transparent
---
### Notes
- Existing projects remain compatible

Hello all,
First release of VoyeSeq is out!
VoyeSeq mimics the Voyetra Sequencer Plus Gold workflow to create patterns,
which can be triggered using MIDI notes from the host.
- *Pattern Bank:* 128 patterns (0-127).
- *Keyboard-Driven Workflow:* Optimized for speed without heavy mouse
reliance.
- *Cross-Platform:* Built with DISTRHO DPF to run as JACK standalone,
LV2, VST3, or CLAP.
- *Start/stop with spacebar:* from VoyeSeq to host through OSC (tested
in Ardour).
Find it here: https://github.com/yellius/VoyeSeq
Enjoy and let me know what you think,
Cheers,
Jelle.
NeuralRack is a Neural Model and Impulse Response File loader for
Linux/Windows available as Stand alone application, and in the Clap, LV2
and vst2 plugin format.
It supports *.nam files <https://www.tone3000.com/search?tags=103> and,
or *.json or .aidax files <https://www.tone3000.com/search?tags=23562>
by using the NeuralAudio <https://github.com/mikeoliphant/NeuralAudio>
engine.
For Impulse Response File Convolution it use FFTConvolver
<https://github.com/HiFi-LoFi/FFTConvolver>
Resampling is done by Libzita-resampler
<https://kokkinizita.linuxaudio.org/linuxaudio/zita-resampler/resampler.html>
New in this release:
* implement option to move (drag and drop) EQ around
Neuralrack allow to load up to two model files and run them serial.
The input/output could be controlled separate for each model.
It features a Noise Gate, and for tone sharping a 6 band EQ could be
enabled.
Additional it allow to load up a separate Impulse Response file for each
output channel (stereo),
or, mix two IR-files to a two channel mono output.
Neuralrack provide a buffered Mode which introduce a one frame latency
when enabled.
It could move one Neural Model, or the complete processing into a
background thread. That will reduce the CPU load when needed.
The resulting latency will be reported to the host so that it could be
compensated.

SpectMorph 1.0.0-beta3 has been released.
This version contains a new pitch detection algorithm for the instrument
editor and it can read mp3 files. Compared to 1.0.0-beta2 there are
mostly smaller fixes, but since some of them address critical problems
we strongly recommend updating to beta3 if you use a previous beta.
There is a tutorial on YouTube for the new features in the 1.0.0 series:
- https://youtu.be/mwVUsuOTcN0
Feedback for any issues you might experience with the beta version is
appreciated.
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.

Website: https://www.spectmorph.org
Download: https://www.spectmorph.org/downloads
There are many audio demos on the website, which demonstrate morphing
between instruments.
List of Changes in SpectMorph 1.0.0-beta3:
------------------------------------------
## SpectMorph 1.0.0 beta3
#### New Features
* Implement pitch detection algorithm for instrument editor and smenc (#31).
* Support mp3 format for static plugins and builds with new libsndfile.
#### Instrument Updates
* Trumpet, French Horn: ping pong loop, better tuning

* Fix crash caused by multiple threads modifying control events.
* Fix CLAP's get factory implementation (#30).
* Various ASAN / UBSAN fixes.
* Fix RTSAN issue: make FFT realtime safe.
* Avoid allocating memory in RT thread if events need to be sorted.
* Fix (unlikely) LineEdit crash.
* Validate input for smenc -m and other utils where an integer is
expected (#31).
* Fix smooth tune performance for long input files.
* Build system updates.
* Convert manpages to markdown.

Hi all,
just wanted to share the good news here that in 2026 the LAC (Linux Audio Conference) is
taking place again, on June 18-20 (Thu-Sat), this time coming back to Maynooth (Ireland)
where it was already hosted in 2011.
Victor Lazzarini, conference organizer, asked me to help in spreading the word about
it, so here we go.
All details on music&paper submission process, deadlines, travel and accomodation etc can
be found at the conference web site: https://lac26.mucs.club/
Greetings, and please feel free to spread the word wherever possible,
Frank
PS: Jeremy: Can you put a corresponding hint into https://lac.linuxaudio.org? Thanks!

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It
doesn't produce any sound by itself, but can be used to drive a MIDI
synthesizer (either hardware or software, internal or external). You can
use the computer's keyboard to play MIDI notes, and also the mouse. You
can use the Virtual MIDI Piano Keyboard to display the played MIDI notes
from another instrument or MIDI file player.

Loopino — New Release: Unified Time, Multi-Engine Character &
Advanced Stretching
This new Loopino release marks a major step forward in timing accuracy,
tonal consistency, and sampler character. By integrating *librubberband*
(standing on the shoulders of giants), Loopino now features *unison note
lengths across the entire keyboard range* — meaning every pitch now
preserves its rhythmic identity while being played musically across the
full scale.
In practice, this means:
your micro-loops, slices and textures no longer shrink or stretch
unpredictably when played higher or lower — they stay locked in musical
time.
Alongside this, Loopino now introduces *multiple sampler engine
simulations*. Each engine emulates different playback behaviours,
interpolation styles and internal timing characteristics inspired by
classic and modern samplers. This allows you to choose not only /what/
you play, but /how/ it behaves — from tight, modern precision to lo-fi,
characterful vintage motion.
These additions build on Loopino’s already powerful creative toolkit:
drag-and-drop sampling, on-the-fly recording, pitch tracking, micro-loop
generation, non-destructive wave shaping, multiple analogue-inspired
filters (Moog, Oberheim, Wasp, TB-303), modulators, vibrato, tremolo,
chorus & reverb, preset handling, WAV export in key, up to 48-voice
polyphony, and a highly flexible standalone environment with ALSA
support and command-line configuration.
New in this Release
*
High-quality time-stretching powered by *librubberband*
*
*Unison note lengths across the full keyboard range*
*
*Multiple sampler engine simulations* for different playback characters
*
Continued performance, stability & workflow refinements
Loopino is no longer just a sampler — it is a time-aware,
character-selectable, performance-ready instrument that blends sampling,
synthesis, and musical timing into one creative engine.
