1. Caustic 2.0 for Android
This music creation tool is optimized for mobile devices and comes installed with instruments and patterns specifically, Subsynth, PCMSynth, Strings, Drone, Bassline, Beatbox and Master controls which are the most common tools for making a basic beat. The only disadvantage to this application is, Android users must ensure that along with downloading Caustic 2.0 which is free, that the 'Caustic Unlock Key' or full version is purchased to allow for external storage and sharing. Caustic 2.0 works similarly to demo versions of music-production software without the unlock key, and as such, will probably restrict saving beats produced.
2. Figure for Apple (iPhone)
Figure by Propellerhead Software AB, creators of the popular music-production software Reasons, introduced software for the iPhone for the musician or producer on the go. The highlights of the phone software are, instruments such as Drums powered by Reasons Kong drum machine and Bass and lead parts by Reasons Thor synthesizer. Though most of the details may relate to individuals in the music industry, the application offers easy-to-use interface, no experience required. Create, edit and adjust levels with the built-in mixer and save directly to your phone's memory or SD card. Or upload music or beats using mobile data to Sound Cloud Sharing, or export to iTunes for friends and family to listen and offer feedback. The app was recently updated last month and works on iPhone 4 or higher.
3. Animoog for Blackberry
Animoog by Moog Music helps users create dynamic sounds while adding motion to each note or synths (electronic instrument with wide range of sound) that can simultaneously be viewed on the computer or television monitors. A fairly new application for Blackberry 10, shows high compatibility with the Z10 models, especially with audio interface, through the use of High Definition Multimedia Interface (HDMI) cables for compact audio-visual transfer and connection to other musical equipment and screens. The app also has a built-in recorder. The application still has a long way to go with the integration of new tools and fixing bugs.
