- Rack files
- Racks saved in the library are
.kbpreset. Racks shared with other players are .kbpatch. Both can be dragged onto the window or opened from the desktop. - What a shared rack carries
- Tracks, mixer state, MIDI settings, effects and their parameters, tempo, transpose and snaps. It never bundles the SoundFonts, and third-party instruments and effects must already be installed on the receiving machine.
- Missing files
- A rack with a missing SoundFont still opens. Relink the file and everything else stays exactly as it was.
- Sound formats
- SoundFonts:
.sf2 and .sf3. Pads: WAV, AIFF, FLAC, Ogg, MP3 and the other formats the audio engine supports. - Instruments and effects
- VST3 on macOS and Windows, Audio Units on macOS. Plugins are scanned outside the main process, so a plugin that fails to scan does not take Keys Buddy with it.
- Audio
- CoreAudio on macOS. WASAPI and DirectSound on Windows, with ASIO available in builds made against the Steinberg SDK. Device, sample rate and buffer size are all selectable.
