The Extreme Drum Pads app is a free Android app for playing virtual pads. The app has a 4x3 grid of pads that can be programmed to 5 different presets: Brutal Dubstep, Modern Urban, Melbourne Bounce, Chip Tune and Progressive. The app was made in 2016 and works on new Android phones and tablets only (Android 4.1 and up). The app works in background and has really interesting sounds in the settings. There is a sequencer that uses a kick, a hat and a snare as well as a 4 measure timeline divided into 4 submeasures. You can change the tempo of the sequencer here that does not affect the general tempo of the app, as well as play and stop the sequencer. There are no actual settings to this app and also, no recording taking place. The best method to use when recording with these kinds of apps is to amplify the app on stereo speakers, turn the volume up and record just like you would record an acoustic only instrument. The Extreme Drum Pads app is a really well-made app that is capable of delivering quality music, as far as your creativity regarding dubstep and trap can go.
