Soundx (com.xenris.sound) on Google Play
** Due to study and work commitments, progress on Soundx has been pretty well non-existent, but I do plan to get back into it when I have the time and have finished my other apps. **-Sound/music producing touchpad/soundpad/synthesizer/synthpad.I have aimed to get the smoothest and most clean sound possible (i.e. without ANY crackles or glitches between notes and volume changes).The intention is to use this in a professional musical sense as well as just for messing about with.Includes so far:Chromatic, major, minor, major pentatonic, minor pentatonic, whole tone and blues scales.Sine, square, triangle and sawtooth sound waves.Settable note range from C0 to B8.Settable vertical axis function (currently only volume or nothing).Working on now:Natural overtones.Many and varied sound effects.User settable buttons and sliders for controlling said sound effects on the fly.Better performance, particularly on low performance devices.Low performance devices will most likely get a crackly sound. (I will try to improve the sound quality for low performance devices, but can't promise anything.)The permissions are just for ads.Enjoy!
