Looking for a creative musical composition and improvisational audio instrument that will keep your inner composer busy for hours on end? Then check out Amidio's Seline HD, a new approach at turning the iPad into a synthesizer optimized for the iPad's screen and touch interface.
Fingering the ioGrid on-screen keypad that triggers notes takes some practice, just like learning any new musical instrument for the first time. Odd notes are positioned for the left hand, while even notes sit on the right side of the split screen. Pitch bends and vibrato effects can be incorporated into the playback by manipulating the circle inside middle diamond shape on the screen. Notes can be stepped up or down using the up and down on-screen arrows accordingly.
