iFretless Bass is a professional virtual instrument that provides bass and guitar players with an expressive fretless playing surface. The layout is like a nine 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.

1) Over 200MB of bass samples

Lots of Fun

Fat Veggie

Lots of fun to play with. For "fret oriented musicians", it's the next best thing to having a physical instrument. With midi, the sounds are unlimited. I'm using it with Sampletank right now.
Wish List: For guitar players, an option to set the 3rd string to a 3rd and leave the rest as 4ths.
For power users, an option to assign each string to consecutive midi channels, starting with channel 1 at the top. Combine that with ios apps like Midibridge or various PC/Mac apps and you'd have a huge range of performance options and tweakability.

Excellent if not for the LOUD cracks


This is a great app and I would rate it 5 stars if not for the loud CRACK that occurs often when you perform a hammer-on. I about jumped out of my chair the first time it happened. It's really, really loud. And, unfortunately, blows the whole sound out. I normally would communicate directly with the developer about this but could not find any way to do that. Please fix this so I can give it a 5-star rating and recommend it to my friends! I'd also recommend setting up a blog so we can direct problems to you instead of voicing them in a review...

Love it With Audiobus, IAA. Fired the Band


iFretless is good. VERY good. It sounds great and the playability is outstanding. It just might be THE best user interface for a stringed instrument in the app universe. You won't find a more authentic sounding bass or a more responsive and easy to play interface anywhere in the known galaxy.

As good as the iFretless apps are, what really impresses me is the regular updates and improvements. While some other apps stagnate, the iFretless apps just keep growing and getting better.
