sites.google.com/site/albertozin/Home/keykit

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
.zipfile, select “Extract All,” and extract it to a simple path such asC:\tools\keykit\. - On Windows, open the extracted folder and double-click
key.exeto launch KeyKit and in the KeyKit console entermidiout("KeyKitPort"). - On Linux, open a terminal, navigate to your download directory, run
unzip key_linux_alsa.zip, thencd keykit, then run./keyfrom inside the keykit folder. - If Linux reports a permission error, run
chmod +x keyand 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 -lagain 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 ~/keykitfollowed by./keybefore launching. - If KeyKit cannot locate its libraries on Linux, set the environment variable with
export KEYROOT=~/keykit. - Copy any additional
.kscripts into thekeykit/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"andmidiout("KeyKitPort")tostartup.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.

BlackPlayer is a comprehensive Android music player that helps you keep all your music files organized on your smartphone and ready to listen to. You can also equalize them for the best experience with each song. And all these features are packaged in a dark and minimalist interface, which is the stylistic hallmark of this player.
Like many other music players, BlackPlayer has several tabs to keep your music organized. At the top of the screen, there’s a list of several categories: song, artist, album, folder, and playlist. You can create your own playlists or opt for smart playlists, which add your most-listened-to songs automatically. The app also tells you how many artists are in your library, as well as the total hours of music at your fingertips. Similarly, BlackPlayer lets you create instant mixes.
Another feature offered by BlackPlayer is the ability to equalize a song’s sound depending on where and how you’re listening to it. You can also choose cover images, complete information, and even add lyrics. This music player’s style is also worth highlighting, as it features a dark theme with colors ranging from black to gray.
