I was looking to make some basic hip-hop beats. I explored what Android drum machines and sequencer apps were available. The following are some of the more useful mobile beatmakers that I found.
SoundFont Drum Machine
SoundFont Drum Machine, also known as SF Drum Machine by Volcano Mobile, is a convenient, easy-to-use drum machine and sequencing app. It includes multiple drum kits with good sample sounds and is available in both a free and paid version.
