xMod is a full-function synth designed for iOS devices. The sound engine is a polyphonic triple-oscillator cross-modulated FM synthesizer. FM is widely regarded as the most efficient way of generating complex "organic" musical sounds. The complexity of programming FM synthesizers is solved in xMod. Two sound banks contain 32 preset patches (programs), with space for 32 of your own. Copy and paste any of our preset sounds into your sound bank and modify the sound easily with a envelope, modulation, and frequency controls. xMod automatically saves your changes. Unique keyboard features include tremolo and pitch bend (vibrato) key controls.

xMod preset programs are displayed in a "sound space" that gives the player the ability to quickly move from one sound to another by simply tapping the icon.

xMod is Audiobus 3 compatible.

A great synth that need Audiobus!

The update takes this synth ALMOST next level. Advanced MIDI options, and Audiobus will make this perfect. I love this synth, and I am really happy they are still updating it. I am just beginning to learn about FM synthesis, and this is a great synth to learn on. This synth is capable of doing much more than it would at first appear. I dialed in some really great, useable sounds right off the bat with no trouble, and had fun doing it! At this point I have to applaud any developer who updates their apps. There are so many apps out there that are really not much more than toys, this is not one of those. This will get used, and that makes me happy. Thank you! I am a fan!
