iFretless Bass is a professional virtual instrument that provides bass and guitar players with an expressive fretless playing surface. The layout is like an eight string bass guitar with the notes colored black and white like the keys of a piano. Although it looks different from a guitar neck, bass players will find it surprisingly easy to use. The app's ability to measure the force of touches on the screen allows it to respond to dynamics and accented notes with a wide range of different tones for each instrument.
