MultiTone News!

I am very happy to announce a great new feature! The addition of audio sequence playback in the MultiTone Tab.

Now you can create any audio type like a tone, sweep or noise and assign a custom duration. Create as many of these elements and play them sequentially, one after the other. Like with a Playlist. Editing is supported as well. Also re-arranging of the elements is implemented. And there is a nice playback control using buttons for prev/next, play/pause and stop.

Tap on the "Play Sequence" button to get started. Three example configurations will be auto-created at the first start.
