The DJ Dubstep Music Maker app is a free Android app for making song sequences. This app has a 5x5 pad grid that you can use with either from the 2 sample presets and also with your own presets. This is so great, as most of the drum pads do not have an option or function for including your own sounds. What this means is that you can use the app as your own custom launchpad. It also saves .wav files that can be used professionally, as they are really accurate. The only issue is that the recorder is using the microphone of the actual device, instead of using internal recording. This means that you can sing with your voice while playing the pads, but that does not usually appeal to dubstep makers. The app is capable of playing in the background of other apps and has really good presets a d is responsive on a device with recent upgrades. A phone or tablet with at least 4.1 in Android OS and a processor speed of at least 1.5 GHz will do. The app has a screen monitor that is capable of showing the waveform of the outputted sound. This is useful when you want to track your sound so as to make sure it does not go overboard. The volume can be set on columns and it would be a great idea to set your sounds in 5 groups, so that you can set their volumes instantaneously. The app has effects for low pass filter, echo and main volume as well as a sample switcher. In order to place sounds on the pad, you have to place the mp3 files in the MySounds folder of your SD card, in the order you want to use them in. The app only knows to repeat the sound sample until you stop it, so make sure that your sound samples are as good as they can be and can be sequenced. This DJ Dubstep Music Maker app is a really functional useful app for putting your ideas together and for making dubstep songs.
