Blip
Synthesizer (Android) updated to v1.5.8 22nd August 2011
Blip Synthesizer is a free fun app
that doesn’t require musical knowledge to play.
The interface is a grid where each
row is for a note in one octave, and each column
represents notes in a pair of 4-beat pattern in a
loop, and each column contains 8 polyphonic tones.
Use the slider at the bottom to
alter the playback speed – it will display the
tempo.
You can add and remove notes, change
scales, change tones, all while music is playing.
