Stopped working

iFretless Bass doesnโ€™t work with iOS26 when using AUM

No support.

Nothing ruins an app quicker than no support. Cool app, great sound but when you save presets in Loopy Pro they save but they donโ€™t change when recalled. Have to hold the gear icon and wait for a countdown then choose preset you want. Multiple inquiries to support with zero response.

DSP usage too high

Maxed out My iPadPro 6th DSP usageโ€ฆ
I am running it in AUM and none of my apps use much DSPโ€ฆ I added iFretless bass and now my DSP is tapping out over 100%โ€ฆ. Disappointing because I love the sound

iFretless Apps open up a whole new world of Instruments + MIDI for Guitarists and Bassists!

How would you like to take your bass anywhere you go and have some AUTHENTIC bass sounds to boot?! Personally, I *LOVE* the Acoustic Bass sound selection, but they are ALL amazing! The value of this app cannot be understated if you are a bassist (or a guitarist). The app allows you to have a bass with virtually LIMITLESS strings and frets! And you can layer more than on bass sound for ENDLESS sound possibilities,

In addition to having a โ€œpocket-sizedโ€ acoustic bass with you at all times - which is a blast just to play along with Spotify/YT music/Apple Music/etc. the sounds themselves are top-notch making this app into a MIDI-controlled instrument! But wait! Thereโ€™s MORE!

This virtual bass fretboard app can also be used as a VERY flexible MIDI controller for guitarists/bassists!

You really need to check this app out!
