MusicCheck is more than a normal midi controller, with our unique Prism Composer you can systematically create or modify a melody in a 3-step process: 1. Specify chords allowed in your melody. 2. Choose a rhythmic pattern for your melody. 3. Select groups of notes you want to vary. MusicCheck runs through all possibilities, for example with 10 chords and 6 groups there are a million different possibilities!!!!!! We use a flexible prism coloured graph representation of all the different possibilities. You can further configure the possible variations by restricting groups to certain chords. Save and load Midi projects and extract the different chords with the Prism-Composer or connect your Midi Keyboard and record new songs. This mobile Midi-studio is able to load SF2 and DLS SoundFonts or you can start right away with some built-in instruments.

**MIDI Pro โ 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.

Verdict
The clearest difference is review sentiment: Music Check at 25% against MIDI Pro's 0%. Music Check also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (9.0 vs 16.0). MIDI Pro's advantage is monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.
