Hi Matt,
<div class=""><br class="">
</div>
<div class=""> The way to use MIDI in ChimeraX would be to include a MIDI / Qt5 library. Qt5 is the window toolkit used by ChimeraX and it controls the receiving of events from devices. I don’t know of an adequate Qt / MIDI library exists. Really we would
want PyQt5 / MIDI since all Qt in ChimeraX is done in Python. The top Qt / MIDI hit is the QMidi library</div>

<div class="">which apparently only handles output of MIDI events, and it sounds like you are primarily interested in input of MIDI events to ChimeraX.</div>
<div class=""><br class="">
</div>
<div class=""> We welcome any recommendations on what PyQt library could handle incoming MIDI events. My quick web search turned up nothing.</div>
