+### MIDI
+
+The synthesizers around the perimeter of the room can be controlled by MIDI either directly or through MIDI-to-CV converters made by [Sixty-Four Pixels](https://six4pix.net/product/cvocd/). The [MOTU Micro Express](https://motu.com/products/midi/micro_usb) MIDI interface in the rack below the main (Tascam Model 24) mixer is connected to the same USB cable. You can talk to the different devices using Max/MSP or other software with the following port list:
+
