MIDI logging, OSC monitoring, and more...
Protokol is a new utility by Hexler for the creator's toolbox: A lightweight, responsive console app for monitoring and logging control protocols.
Originally built as a MIDI monitor and Open Sound Control network checker, Protokol is designed to handle any complex message stream.
MIDI, OSC, Art-Net and Gamepad controller sources are all supported in the current version - but anything is possible given sufficient demand. Contact us if you'd like to see additional protocols added: Let us know.
