### 4/5 — Hmm…

*2024-02-25*

This filter possibilities are very nice. Unfortunately it does not log messages if app is in background (at least on my iPad). This way I cannot send a MIDI message (e.g. sysex) via TouchOSC and see filtered MIDI messages/response here. Of course, it would be much better to have this filter possibilities directly in TouchOSC.

### 5/5 — Fantastic

Thank you very much for this super handy app. This is how a MIDI and OSC monitor should be done!
