## Most critical reviews (3 lowest-rated)

### 1/5 — Save your money!

*2021-05-08*

App stops working randomly and adds latency

### 1/5 — After iOS14 update it crashes in Audiobus

*2020-11-08*

Please update this app, I use it a lot. I haven’t checked your other apps yet hopefully some of them still work.

### 5/5 — Yay, thanks for white-keys scale mapping

*2017-06-15*

For those who don't know already, this handy app is designed to go between an Audiobus 3 Midi input and output. It takes the incoming Midi notes and maps them to a scale of your choosing or creation, basically helping you to never play a wrong note. 

Now you can also make it so that the scale maps to just the white keys, so you can, say, play an F# Hungarian minor scale just as you would a C Major.

That's only the beginning of the many things this can do for you, especially when combined with the several other single purpose apps from this series. I highly recommend just grabbing the full bundle, whether you see a need for them all at this time.

(Johannes, if you're reading this PLEASE make a free-form Midi note mapper that can transform any note to any other. This would be helpful for dealing with all the different mappings used by drum apps. Thanks!)
