Maar Nuo 4 heeft geen midiclock als ik me niet vergis, alleen midi aansturen op rottary's en faders.. de Xone:3D heeft het wel, maar dat is ook wel een geweldige mixer alleen heb een prijs voorbij horen komen van 2000€ en dat vind ik toch wel net een beetje veel geld 
uit het NOU4 manual:
6.4.1. MIDI Clock
The NUO4 transmits a standard timing message named MIDI Clock, to synchronize one or several external MIDI
devices. The synchronization signal is the same message sent 24 times per quarter note.
To control a MIDI device, remember this device has to operate in slave mode (external Clock).
The NUO4 has no internal processor for BPM calculation. The tempo for a specific musical part has to be manually
set, repeatedly pressing the TAP button (a minimum of 5 times) to the desired tempo. The TAP button blinks to the
BPM rate you established.
A more precise BPM adjustment can be done assigning one of the MIDI controls to this function with
Ecler Control 4 Lab software.
MIDI Clock can be deactivated by holding down the TAP button more than 3 seconds. When this happens, TAP
button does not blink. Once deactivated, it will not operate until you explicitly activate it by holding down the TAP
button more than 3 seconds. The selected mode will be maintained after shutdown.
Tempo default value is 120 BPM after each shutdown or MIDI Clock activation.
6.4.2. Start, Stop and Continue messages
When an external device is synchronized by MIDI Clock, standard Start, Stop and Continue messages are used to
control the playing.
