--- layout: default title: Setting Up MIDI ---
CoreMIDI is the standard MIDI framework to comunicate with MIDI hardware on OSX systems. It provides drivers and libraries needed by MIDI clients. These ports do not show up in qjackctl
ALSA MIDI is the standard MIDI framework to comunicate with MIDI hardware on Linux systems. It provides drivers and libraries needed by MIDI clients. These ports show up under the "ALSA" tab in qjackctl
JACK MIDI is a framework used to comunicate between JACK MIDI software clients. It provides zero jitter and a fixed latency of 1 "period" (the same latency that exists for audio). These ports show up under the "MIDI" tab in qjackctl.
Various ways of "bridging" between the native MIDI framework (e.g. CoreMIDI or ALSA) and JACK MIDI, as described in the sections below.
