You can combine and rearrange these bars arbitrarily and edit them in piano roll. Tempo is chosen automatically, however it can be simply changed as well as key. All notes are picked by the algorithm. Currently you can choose from default rap, lo-fi, chiptune, cinematic or dance styles. Each of these styles brings unique music experience. You can also activate chord progression builder to define exactly what chords will Beatly use in the generated bars or create your own bar patterns which will be consequently used by the algorithm when building a new track. To modify already generated chord progression in the track you can change key/base chord of each beat within a bar. All notes of given beat will be transposed appropriately. Run app, tap the play button. It is that simple. Music will be different each time you hit the reload button. Once you're done editing the tune, simply save it for later, export to MIDI or record your live session to WAV audio file. You can even render separated stems or seamless loop of your entire track. You can also hook up Beatly with your favorite mixer using MIDI output. Drums too loud? Adjust the volume. Synth annoying? Mute it or try other built-in sounds. Loving the sound of piano? Solo it and make it shine. Mixer got your back! Need variation? Reload any instrument part of your track. Generated part not to your liking? Leverage the piano roll to fix algorithm's mistakes and make it awesome! Can I import my own samples? Yes! You can attach or record your very own WAV or M4A sound to any instrument track. Just bear in mind, samples tuned in C will sound best! :) If you like Beatly Pro, please, support us by rating this app in the App Store or donating via in-app purchase.
