**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.

Features
Read full description

Cab ML is both a standalone app and an AUv3 plugin that provides a neural network for impulse response generation. By moving tags in a window you can change the impulse response in an interactive way. Underlying a neural network will generate an impulse response based on the position of the tags. Instead of trying out all your impulse response files through a classic impulse response loader, you can now find the right sound interactively by moving the marks until you like what you hear. Furthermore Cab ML also provides a poweramp with many options and a microphone reverb generator. The free version allows you to test Cab ML completely, but every minute the plugin will be silent for 3 seconds. To remove these limits there is a one time in-app purchase. You need an audio interface to connect your instrument to your Mac. Known audio interface brands for guitar or bass are for instance Focusrite or iRig. If you don't have an audio interface, you can use the AUv3 plugin in a DAW such as GarageBand or Logic Pro. Any (guitar/bass) sound you have recorded can be fed through the Cab ML audio unit.
