Fantastic

Thank you just what I needed.

Hmm…

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.

Excellent!

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