You can set the location for your Audio Evolution Mobile Soundfont directory - the place/folder where your soundfont and SFZ instruments are stored - from within the Other section of the Settings. You can also create your own SFZ instrument from within the app and you can, of course, add other soundfont/SFZ instruments directly to the Soundfont folder in the Audio Evolution Mobile folder on your device. SFZ files are simple text files which contain all of the similar information about how the sampler should use the audio samples when triggered by midi events, but this time the audio samples are contained in a separate folder.Īudio Evolution Mobile not only has a General MIDI (GM) Default Sound Set with a full range of instruments but also has a Soundfont Shop from where you can buy a full range of professional quality soundfont instruments from Digital Sound Factory as in-app purchases. Soundfonts are single files which contain the audio samples and the format's instructions as to how they are allocated across the keyboard range and triggered by incoming midi events. You can also create your own SFZ instruments. The Audio Evolution Mobile sampler allows you to use Soundfont and SFZ instruments.
