ProChords is an app for iPhone and iPad which lets you create chord progressions in a spontaneous and intuitive way. The app works as follows. You choose a number of chords in a certain key, press the app’s record button and go jamming like crazy until something interesting occurs. After recording the jam, you download the recorded MIDI file from the ProChords server to your computer and then import it into your favorite digital audio workstation (DAW).
ProChords gives some great chord suggestions after you’ve chosen a certain key. So you can easily choose the chords you want to jam with. You can directly listen to the suggested chords via the built-in piano to get an idea how they sound together.
This app costs € 7. Curious? This video says more than words:
