<p>Many of the USB devices I have been looking at for control surfaces are midi-centric, primarily coming out of the music industry.</p>
<p><br>
</p>
<p>For simple devices, not going the midi-route is usually straight forward, although can get complex supporting cross-platform. </p>
<p><br>
</p>
<p>For complex devices such as DS1, <span style="font-size: 12pt;">midi appears to be the best method for dial boxes.</span><span style="font-size: 12pt;"> There is also economical advantages and an ongoing evolution of such devices.</span></p>

</p>
<p><br>
</p>
<p> It also allows one to take advantage of manufacturer software in configuring baseline operational conditions (setting dial colors, ranges, toggling action of buttons).</p>
<p><br>
</p>
<p><br>
</p>
<p>We have talked about midi in the event loop before. At the time it was not clear how/if this could work under chimeraX.</p>
<p><br>
</p>
<p>Any further ideas?</p>
