5 stars and even a little bit more maybe...

Kai, this is the best midi monitor I have seen on iOS (well.. iPad OS), PLEASE bring it to the iOS system too! I would love this on my phone.

Worth every penny!

I need to see MPE Midi streams across a WiFi network and using my iPad Pro with MIDISpy is great. Very reliable as a stand-alone app, or as a plugin in AudioBus, AUM or as a AUv3.

Would like to see an option to save output but I can copy and paste so it’s not a big deal.

I really hope you port all of your apps to macOS. Please always make sure that MIDI over WiFi is solid on your end, (I’m sure that’s mostly up to the OS), and support MIDI 2.0 and MIDI.org standards. I rely on this for my living.

Bluetooth Support Non Existent

Everytime I try to connect Bluetooth midi app crashes. Using an airturn quad200, but I don’t think it’s the device because the menu isn’t even coming up. Tried closing every other app, everything. Please fix because this app is so important for what it does.
