Export midi loop function not documented enought ?

After browsing the manual… no result for “export midi loop”,
can’t find the section

so posting this as reminder and for others >

export midi loop function is working ONLY on instrument tracks,

so if you have midi on a midi track ( ie : to send to external synth / sampler…)
you have to create an instrument track >> copy the midi events to it >> and then you can save the midi loops.
