iTunes link: Bloom – £2.39
Developed by musicians Brain Eno and Peter Chilvers, Bloom is an interactive music generation app that lets you create soothing ambient music by tapping on different areas of the iPhone’s screen. The software creates a 'bed' of soothing synth sounds over which you add your own melody.
Tapping at the top of the screen plays high notes, while tapping towards the bottom plays lower ones. The app takes the notes you enter, quantises them to fix timing errors and then creates simple loops from them. You can select different moods to adjust the feel of the music that the program creates and also adjust other settings like the sound used for the lead melody and the length of the delay (echo).
Bloom is not just a beautifully original app, it’s a very addictive one.
