Exactly what I needed

This is exactly the app I need to troubleshoot midi outputs of audio equipment. I am using a USB Mio plugged into my iPhone. It is simple and effective.

Great free tool

Super useful for debugging midi devices. The only thing I could really want is if column headings stayed at the top of the page when live data was scrolling. But I can memorize 3 columns. Thanks for the great app!

Does what it should!

This works great for verifying the messages coming from my various Bluetooth controllers. Simple and easy to set up, and the data is presented in a format that a relatively unskilled user like me can understand. Excellent!

Affichage message sysex limité en caractères

L’affichage d’un message sysex est limité à 9 caractères et donc impossible de voir un message supérieur à cette limitation
Dommage mais application utile quand même !!!
