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.

1) 13 deeply sampled bass sounds
2) MIDI input and output
3) Audio Unit 3 support
4) Audiobus support
5) Parametric Equalizer
6) MPE multi-channel MIDI support
7) Accurate touch force sensing, even on devices that don't support 3D touch

1) Fretless bass
2) Slap bass
3) Jazz bass
4) Acoustic upright bass

This app is great to play and sounds awesome. It’s the ONLY realistic bass guitar sim in the App Store as far as I know. There are others but they are ALL crap IMHO. There is one addition that would make this app even more killer. A sustain button somewhere in the corner that you would touch and the note you hit would continue until the next one is hit. This would allow a nice even single note rhythm without the nanosecond of silence every time you lift your thumb to hit the same note over and over. Please, this would be RAD!!! Otherwise it’s worth every penny. Thank you my friend for such an easy to play and realistic sounding bass sim!

A secret trick: you can press two fingers on the same note at the same time; this allows you to trigger a new note without leaving that nanosecond of silence between them.

Amazing New Update

I didn’t think you could get any better. With this new update it sounds scary natural! I’m definitely an acoustic kind of musician and without having to spend a lot of money on bass I just use this app to do my recordings. I graduated from the Institute of Audio Research and a pretty talented singer songwriter/musician so I’m pretty picky about my sounds, that said, I have no complaints no I change anything about this app. Seriously, it’s awesome.

Very good, can be better.

I am handicapped and this allows me to be a bassist again.

Except for the Upright Bass, the sounds are very good—certainly enough for gigging which I do.

The upright bass is horrible and useless. Oh well, you can’t have everything.

I found a bug that will not bother must users. When you quit iFretless Bass, it doesn’t quit completely. If you only tap the screen, you won’t notice it but, if your keyboard is connected to your iOS device, any other sound library will be odd because your keyboard will still trigger iFretless Bass (your keys just have to be hooked up. It still happens if you tapped the glass on the bass). Drove me nuts till I figured it out. The workaround is easy enough—shut down your iOS device and restart. Time consuming and annoying at a gig. I didn’t notice this bug with the iFretless brass and wind libraries.

Except for that and the upright bass, sounds great and works fine.

Developer Response ,

Thanks for your feedback. The background audio feature is designed to allow you to play iFretless together with other synth apps. If you don't want to hear sound when it's in the background, please set the MIDI input source to NONE in the settings menu.
