Install Procedure:

  • Navigate to the KeyKit GitHub repository (nosuchtim/keykit).
  • Open the /dist/ directory.
  • Download the appropriate archive for your system: Windows (key_nt.zip), Linux (key_linux_alsa.zip), or Raspberry Pi (key_raspbian.zip).
  • On Windows, right-click the downloaded .zip file, select “Extract All,” and extract it to a simple path such as C:\tools\keykit\.
  • On Windows, open the extracted folder and double-click key.exe to launch KeyKit and in the KeyKit console enter midiout("KeyKitPort").
  • On Linux, open a terminal, navigate to your download directory, run unzip key_linux_alsa.zip, then cd keykit, then run ./key from inside the keykit folder.
  • If Linux reports a permission error, run chmod +x key and then ./key.
  • Install a virtual MIDI driver on Windows (for example, loopMIDI).
  • Launch the MIDI driver and create a virtual port (for example, KeyKitPort).
  • Route the virtual MIDI port to a sound source such as a software synthesizer, DAW, or virtual MIDI instrument.
  • On Linux, verify MIDI devices by running aconnect -l.
  • Start a software synthesizer on Linux, for example fluidsynth -a alsa -m alsa_seq soundfont.sf2.
  • Run aconnect -l again to view available ports.
  • Connect KeyKit to the synthesizer using aconnect <keykit_port> <synth_port>.
  • In the KeyKit console, type 'c d e f g' and press Enter to test audio output.
  • Load a built-in sequencer by entering load "lib/seq.k" in the KeyKit console.
  • Optionally load a demo by entering load "lib/demo.k".
  • Ensure KeyKit is always launched from its root directory.
  • On Windows, if using a shortcut, set the “Start in” field to the KeyKit folder path.
  • On Linux, always run cd ~/keykit followed by ./key before launching.
  • If KeyKit cannot locate its libraries on Linux, set the environment variable with export KEYROOT=~/keykit.
  • Copy any additional .k scripts into the keykit/lib/ directory or your working directory.
  • Load additional scripts in KeyKit using load "myscript.k".
  • Create a startup script by making a file named startup.k.
  • Add commands such as load "lib/seq.k" and midiout("KeyKitPort") to startup.k.
  • Load the startup script in KeyKit using load "startup.k".
  • If KeyKit produces no sound, confirm MIDI devices exist and are properly connected.
  • If KeyKit fails to start, confirm you are running it from the correct directory and that permissions are set correctly on Linux.

iscream ~ MacOS Audio Recorder

Posted by tom2tec on

iScream is a free recording application for macOS. It lets you record sound from your microphone or other sound sources. The app sits in the Dock, so when you want to start recording, just click its icon. To stop recording, click the icon again. With support for hotkeys, it’s even easier to start and stop recording without reaching for your mouse. iScream is great for making voice notes, capturing quick sound bites, recording short interviews, and any other small recordings you might need. Its simple design and easy-to-use features make it a handy tool for anyone, especially those who often need to capture audio on the fly.

  • One click recording
  • Saves in MP3, AAC or WAV format
  • Hotkeys support

The modules are also available as LV2 plugins with Qt user interface. QMidiArp has been growing since June 2009 on top of Matthias Nagorni’s original arp idea.

Features:

  • Programmable arpeggio patterns, LFO waveforms and sequences
  • Modular setup of arpeggiators, MIDI LFOs and step sequencers
  • MIDI-controllable (MIDI-Learn)
  • Synchronization with MIDI Clock or JACK Transport possible
  • Optional triggering by keyboard or continuous play mode for all modules
  • Patterns can be stored and switched by MIDI control while running

AudioGridder ~ Audio & MIDI Network Bridge

Posted by tom2tec on

AudioGridder is a network bridge for audio and MIDI that allows for offloading the DSP processing of audio plugins to remote computers. This can come in handy when mixing complex projects or running CPU intensive instruments.

AudioGridder Server runs on a computer hosting your effect and instrument plugins. On your workstation, on which you run your DAW, you use the AudioGridder FX or instrument plugin to access your plugin library over the network. The plugin is looking for available servers on your network and once connected allows you to create insert chains or load instruments. Midi and audio data from your DAW will be streamed over the network, processed on the server and streamed back.

SDIF ~ Sound Description Interchange Format

Posted by tom2tec on

The Sound Description Interchange Format (SDIF) is an established standard for the interchange of sound descriptions and analysis data. This project provides libraries, SDIF (in C) and Easdif (in C++), tools, and wrappers to read and write SDIF files.

Lattice ~ CLI Toolkit For Music Collectors

Posted by tom2tec on

A high-performance CLI toolkit for music collectors who manage their own libraries. Lattice provides a suite of tools for library visualization, integrity verification, cover art extraction, and metadata auditing — all from a single, zero-dependency script.

Why this exists

Modern music players often hide your library behind proprietary databases. Lattice is built for collectors who treat the filesystem as the source of truth. It reads tags directly via mutagen, ensuring your library is portable and player-agnostic.

Features:

ModeFlagDescription
Library Tree--libraryGenerate a formatted ASCII/Unicode tree of your entire collection.
AI Library--ai-libraryToken-efficient export designed for LLM recommendation prompts.
Genre Wings--all-wingsGenerate separate library catalogs segmented by genre.
Integrity Checks--testFLACParallel verification of FLAC/MP3/Opus/WAV integrity via FFmpeg.
Art Extraction--extractArtExtract embedded covers with format-priority ranking (FLAC > Opus).
Tag Audit--auditTagsIdentify and report files with missing or inconsistent metadata.

Bitfake2 ~ Audio Tool Handler & Manipulator

Posted by tom2tec on

Bitfake was originally created to detect fake .FLAC files through spectral analysis. It has since grown into a multipurpose CLI tool for handling music more easily and efficiently.

One common problem was that getting a track’s metadata required long ffprobe commands with messy output. Converting music with ffmpeg was also repetitive. The command itself is easy to remember, but writing scripts to convert entire directories felt inefficient and slow. This project now performs metadata and conversion tasks directly through linked libraries (TagLib/libsndfile/libav*).

Features:

  • Get metadata
  • Get ReplayGain info (useful for music players)
  • Spectral analysis on 44.1 kHz .FLAC files (higher sample rates may be misrepresented, so be careful)
  • Lossy diagnosis (banding score)
  • File Conversion + VBR Support (Works for outputs like .wav, .flac, .ogg, .mp3, .aac, .opus)
  • Tagging metadata (Works for single files, but not directories yet)
  • Calculating ReplayGain and applying it to files (Works for track replay gain iterating through directories, album replay gain is a bit funky?)
  • Directory Conversion (works for all previously mentioned formats!)
  • CoverArt+ (Brings along cover art among all conversions!)
  • Organizing Files by album! (Give a dir of random music, and bitfake will organize it – ty to uncognic)
  • Directory Tagging (YAY!)
  • Album folder renaming from tags (Artist – Album (Year))
  • Spectrogram generation (in .png)
  • Version info (WOW! BEST YET!)
  • MusicBrainz Syncing data.

Ear Tag ~ Edit Audio File Tags

Posted by tom2tec on

Ear Tag is a simple audio file tag editor. It is primarily geared towards making quick edits or bulk-editing tracks in albums/EPs. Unlike other tagging programs, Ear Tag does not require the user to set up a music library folder. It can:

  • Edit tags of MP3, WAV, M4A, FLAC, OGG and WMA files
  • Modify metadata of multiple files at once
  • Rename files using information from present tags
  • Identify files using AcoustID

Network access is only used for the “Identify selected files” option.
