Almost all electronic music is synced to a sequencer and so obviously is going to have a very steady tempo.
Haha if only
Well the tempo is steady by human standards, but latency and jitter on timing signals are recurring issues in electronic music. Some devices put out very steady timing but don't like being slaved to another device, bugs can creep in at loop points or pattern switching (even on Roland's latest flagship drum machine, which costs most of $3000), things can get messy if there is too much note/controller data and so on.
Usually top electronic studios use external clock sync device which prevents that kind of issues, I’m sure that Daft Punk uses it too
Yeah, it's a really bold claim by someone who obviously never had to sync midi gear, which can become a nightmare depending on the gear. The problem is so difficult that we have specialized expensive sync gear that try to tackle it.
