**MIDI Pro — Backing Tracks and Composition Ideas** MIDI Pro helps musicians practice, experiment with musical ideas, and create MIDI sequences that can serve as starting points for original compositions. Whether you're practicing an instrument, exploring chord progressions, or developing a new song, MIDI Pro provides customizable percussion and melody tracks to play along with. **Create Your Own Musical Ideas** MIDI Pro combines structured musical rules with an element of randomness to generate unique MIDI sequences based on your preferences. Choose a rhythm, key, scale, and chord progression to create music tailored to your style. Each generated sequence includes percussion and four melody tracks that can be individually adjusted, allowing you to experiment with different musical arrangements. **Practice and Play Along** Selectively enable or disable percussion and melody tracks to create backing music for your preferred instrument. Explore different combinations of rhythms, melodies, and harmonies to inspire your playing and compositions. **Built-in Instrument Tuner** Use MIDI Pro's built-in tuner to tune your instrument before practicing or playing along. The tuner detects the pitch of notes played through your device's microphone, helping you get your instrument ready to play. **Import and Play MIDI Files** Open MIDI files directly from the Files app on iPhone and iPad, or from Finder on Mac. Use MIDI Pro's built-in player to listen to imported MIDI files and navigate through them using playback controls. **Save and Continue Creating** With the paid version, you can save generated MIDI files for later use or import them into your favorite Digital Audio Workstation (DAW) to develop more complex arrangements. MIDI Pro is designed to complement your creativity, providing musical ideas and a flexible environment for experimentation, practice, and composition.
