Protoplug ~ Scriptable Audio Plugins


Create audio plugins on-the-fly with LuaJIT.

Protoplug is a VST/AU plugin that lets you load and edit Lua scripts as audio effects and instruments. The scripts can process audio and MIDI, display their own interface, and use external libraries. Transform any music software into a live coding environment!

Cross-platform: builds for Windows, Mac OS X and Linux. This means that all protoplug scripts are compatible with these platforms and can be loaded into a huge amount of audio software (glory to JUCE).

Fast: Use the speed of LuaJIT, and perform DSP tasks as efficiently as old school C implementations.

Free and open source: Want a new feature? Add it yourself. The source is MIT-licensed and available on Github.

ANMP ~ Another Nameless Music Player


ANMP aims to be a versatile but lightweight audio player, just as the other hundred thousands out there. It is written in C++11. As being only a frontend, ANMP itself doesn’t know anything about audio formats and how to decode them. That’s why it uses 3rd party libraries to decode them. By using VgmStream, GameMusicEmu, LazyUSF and supporting looped songs natively, ANMP is esp. suited to play various audio formats from video games. Moreover it supports Looped Midi Tracks.

Main Features:

  • muting multichannel audio files
  • gapless playback (for most streamed audio formats)
  • arbitrary (forward) looping of songs (i.e. even nested loops)
  • synthesizing MIDI files using fluidsynth
  • multi-channel audio rendering
  • overlapping notes do not kill each other
  • unrolling looped MIDI tracks
  • volume response compatible to N64’s software synth
  • supports an IIR lowpass filter compatible to Rareware‘s N64 games (Conkers Bad Fur Day, Jet Force Gemini)
  • support for cue sheets
  • support for audio normalization based on EBU R 128
  • exposes basic commands via D-Bus

Speedy MIDI ~ Easy MIDI Editor


Speedy MIDI is an editor designed for choirs and singers to quickly generate MIDI files for rehearsal.

Focus is on fast and easy note entry

If the quality of the sheet music is too low for scanning, Speedy MIDI is an interesting alternative to other MIDI or notation editors. Use the mouse piano for input, or an external MIDI keyboard.

Cell raster technique

Note lengths are entered in multiples of the current cell length.
Thus entering dotted notes or ties is not needed any more!
Tuplets are fully supported.

Simultaneous entry in multiple tracks

Speedy MIDI automatically distributes multiple pressed notes to multiple tracks. This helps when entering music with same rhythmic patterns in multiple voices, e.g. chorale music.

Features:

  • unlimited undo/redo
  • part extraction
  • rehearsal markers (verse, chorus etc.)
  • transpose
  • adjustable playback speed
  • swing playback
  • shortcuts for all commands
  • compatible file format: Standard MIDI File (.mid)
