Where is MIDI on the UFX I cannot see any MIDI sockets!The 5 buttons of the transport section of your UFX mixer can send and receive MIDI data. Receive Yes,they can! In fact this means that you can switch on/off the light of each button individually by MIDIcommands from your DAW/MIDI software. But mostly you will need these buttons to send commands toyour DAW/MIDI software, for transport control of your recording engine.How to prepare MIDI operationo Set your UFX into USB- or FireWire-operation with the rear MODE switch.o Connect with the corresponding cable (USB or FW) to your computer.o Windows users > install the USB- or FireWire driver.o OS X users > select UFX as your MIDI I/O device at the Audio-MIDI-Setup utility.o Open your DAW or MIDI program (Win/OSX) and select UFX as your MIDI I/O interface.o Now you can assign the buttons via learn command in your DAW, or use the Mackie Control mode.Which MIDI modes are availableThere are 2 MIDI modes:o Standard mode (Std in the display while booting/powering on): The UFX sends note commandsand receives CC commands (for the button LEDs). Normally you will use this mode if you want toassign individual functions to the buttons or if your DAW does not support the Mackie Controlprotocol.o Mackie Control mode (MAC in the display while booting/powering on): This is the easiest way toremote control the transport section of your DAW. Just select Mackie Control mode in your DAWand on your UFX, and here we go! In this mode the button LEDs correspond to the Mackie Controlprotocol, and it doesnt matter if you press a transport button in your software or on your mixerhardware, both will work and update the button light of each other.How can I change the MIDI mode for the transport sectionThis can only be done while booting phase of the UFX. This happens after powering on the mixer or ifyou change the rear MODE switch position:o Press and hold down the >> button (Fast Forward)o Power on the mixer (or change the rear MODE to USB or FW)o Wait until Std (Standard mode) or MAC (Mackie Control mode) gets indicated at the displayo Now release the >> buttonNOTE: If you want to change from Std to MAC or vice versa, repeat the above steps.NOTE: The MIDI mode change works only in USB- or FireWire-mode, but not in STAND ALONE mode.Why doesnt the display indicate anythingIn USB- or FW-mode the transport section is a MIDI controller and the display has no function (apartfrom indicating the selected MIDI mode while boot phase).Why are the button LEDs of the transport section off if I press any button in USB or FW modeThats normal by default in Standard MIDI mode (Std). If you want to get the LEDs triggered, you haveto assign them in your DAW. In Mackie Control mode (MAC) you dont need to assign, you will see thatthe LEDs get triggered automatically if you select the appropriate protocol in your DAW.How can I assign the transport buttons in Standard MIDI mode (Std) for USB- or FW-operationHere an overview (TX = transmit, RX = receive):o Rewind button (<>): TX = note 2 (D-1) / RX = CC2o Rec button (o): TX = note 3 (D#-1) / RX = CC3o Stop button (): TX = note 4 (E-1) / RX = CC4o Play button (>): TX = note 5 (F-1) / RX = CC5NOTE: All MIDI data have to be transmitted on MIDI Channel 1.NOTE: TX (sent notes): Button down = Note On = value 127 / Button release = Note Off = value 0NOTE: RX (received CCs): CC with value 0 = button LED off / CC with value 1-127 = button LED onWhy does the MIDI communication for the transport section not work in STAND ALONE modeIn STAND ALONE mode the transport section operates as a stand alone USB recorder with externalconnected USB hard-disk drive, but not as an (audio or MIDI) interface for the computer.
