A fully free and self-contained modular synthesizer based on the popular VCV Rack. Available in AudioUnit/CLAP/LV2/VST2/VST3 plugin formats and as a standalone app for FreeBSD, Linux, macOS, Windows and the Web.
DISTRHO Ildaeil is mini-plugin host working as a plugin, allowing one-to-one plugin format reusage. The idea is to load it as a plugin inside your DAW and then the other “real” plugin inside Ildaeil. This allows, for example, a VST3 host to load LV2 plugins and vice-versa.
The Ildaeil name comes from the korean 일대일, which means “one to one”.
Features:
The current formats Ildaeil can work as are:
JACK/Standalone
CLAP
LV2
VST2
VST3
And it can load the following plugin formats:
Internal (from Carla)
LADSPA
DSSI
LV2
VST2
VST3
CLAP
JSFX
With a few extra formats through the “Load from file…” action:
Audio files (through internal audio file player, synced to transport)
MIDI files (through internal MIDI file player, synced to transport)

DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that’s has been recorded with a multi mic setup.
Features:
Stand-alone, Lv2 and VSTi versions available
Open drumkit file format, allowing the community to create their own drumkits
Drum velocity, allowing for several different hit velocities for each drum
Multichannel output, making it possible to mix it just the way you would a real drumkit
Optional built-in humanizer, analyzing the midi notes, adjusting velocities on-the-fly
Stand-alone midi renderer, generating .wav files, 1 for each channel
Stand-alone midi input, making it possible to use DrumGizmo as a software sampler for an electronic drumkit
LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform.
Features:
Plugins available in LV2 format, native X11 UI is provided
Plugins available in LADSPA format
Plugins available in LinuxVST format, native X11 UI is provided
Standalone plugins available as JACK applications, X11 UI is provided
Highly-optimized source code for x86 and x86_64 architecture with support of SSE, SSE2, SSE3 and AVX instruction set
Highly-optimized source code for ARMv7 architecture with support of NEON instruction set
Source code and binaries are available for free download
Advanced GTK+ Sequencer is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel.
It’s designed to be highly configurable, you may add effects to its effect chain, add or remove audio channels/pads.
You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines.
In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that’s why you need at least a preemptible kernel.
Features:
save or open Advanced Gtk+ Sequencer XML files with XPath support
add or remove audio engines with adjustable audio channels and pads
link channels with property dialog
output panel, mixer, drum and matrix sequencer, soft synth and audio file player
piano roll with basic notation editing supporting copy & paste
adjustable BPM
LADSPA, DSSI and Lv2 support
export to WAV, FLAC, OGG and others
multiple sinks like Pulseaudio, JACK, ALSA and OSS
This is the community version of Element, a modular AU / LV2 / VST / VST3 audio plugin host. Create powerful effects, racks and instruments by connecting nodes to one another. Integrates with your existing hardware via standard protocols such as MIDI.
This is an OpenGL bars visualization plugin (as seen in XMMS and XBMC/Kodi). It’s adapted from the jack_glbars project by Nedko Arnaudov. glBars works as a JACK standalone and audio plugin (LV2 or VST).
Dexed is a multi-platform, multi-format plugin synth that is closely modelled on the Yamaha DX7. Dexed is also a midi cartridge librarian / manager for the DX7.
Features:
Multi platform (OS X, Windows or Linux) and multi format. (VST, AU, LV2)
144 DAW automatable DX7 parameters available from one single panel.

synthesis of melodic and percussive instruments
bundled collection of instruments
support for dynamic parameterization and automation
rigorous implementation of the MIDI standard
