16 July 2022 - Version 1.2.0 Released

Konfyt 1.2.0 has been released!
Get it at:

The eagle eyed viewer will notice that the version number now sports a brand new middle digit with a zero at the end. Despite an optimistic effort to make a quarterly release in April, I couldn't get the changes that I wanted to make done in time. So now here we are a few months later. There is still a lot to do, but I didn't want to miss another release opportunity.

The MIDI filter now has a note velocity map, with a pretty graph and factory as well as user presets. This replaces the velocity min/max and limits that were previously in the MIDI filter. When loading an older project, the old velocity min/max and limits will be converted to a velocity map.

Another notable pair of new features is the automatic restarting of Linuxsampler if it happens to crash, and running soundfont scans in a separate process so malformed soundfonts don't crash Konfyt and can safely be ignored.

A full changelog can be found on the release page, linked above.

Fixes: Changes: Enjoy.

23 August 2021 - Screen Lock Bug (Xfce, Light Locker)

I came across a strange bug this weekend. When the screen is locked, MIDI triggers don't work and the actions only take effect once the screen is unlocked. Normal functionality (audio, MIDI, SFZ and soundfont playing) still works. Only MIDI triggers that are assigned to actions in the GUI are affected.

This happens under Linux Mint 20.2 (so presumably all Ubuntu based systems) with Xfce using Light Locker.

This seems to be due to a Qt bug. A workaround is to set an environment variable. More info can be found at the Known Issues section in the documentation.

Aside from a few minor GUI and other tweaks, the only notable change is slider MIDI pickup - a range value can be set in the Triggers screen which will determine how far sliders will jump to match incoming MIDI values.

12 January 2021 - Version 1.1.3 Released

Konfyt 1.1.3 has been released!

Most notable changes include multiple instances sharing Linuxsampler, the ability to reorder patches, some GUI tweaks, bug fixes and behind the scenes code improvements that will hopefully improve maintainability.

2 January 2021 - New Documentation

The Konfyt documentation is now hosted at konfyt.readthedocs.io.

14 October 2020 - Version 1.1.2 Released

A lot of the code was refactored for this release in order to support per-layer MIDI indicators as well as general design improvements. The addition of global and per-layer sustain and pitchbend indicators allows the user to troubleshoot stuck MIDI problems at a glance.

This is regarded as stable (I use it daily) and will graduate to non-beta state after some more testing.

24 September 2019 - New MIDI send list feature in testing

A very handy new feature, MIDI Send List, has recently been added to the testing branch on Github.
Each MIDI output port layer now has a MIDI send list - a list of MIDI messages that are sent when the patch is activated. This allows you to switch programs on external synths when you switch to a patch.
This will stay under testing for a while until I'm sure it's stable, after which I'll move it to master and release an official new Konfyt version.

23 September 2019 - Intro Video

An introduction video is now available on Youtube: here.
The video illustrates the very basics of using the library to find sounds, creating patches, basic MIDI filtering and assigning MIDI triggers to switch pathes.

22 September 2019 - Welcome to the news

Initial commit.
Hello world.
Test 1-2.

Welcome to the new news section. I'll post some development progress here. Hopefully. I think.
